Various Types Of 2 Way Radios

Writen by Michael Perry

Radios that can receive and transmit communications are known as 2 way radios. Some common examples are walkie-talkies, CB radios and even cellular phones. While these products are very different in nature, they are common in that they receive and transmit communication and are classified as 2 way radios.

There are many uses for 2 way radios, including a camping trip with the family where walkie talkies help everyone to stay in touch. When in the wilderness, a cell phone is not likely to have a signal and this is why walkie talkies are so helpful. If individuals should get separated from one another while camping, having a way to remain in communication is invaluable. In order for 2 way radios to work, individuals must be on the same frequency or channel to communicate. Before separating, families should make sure that everyone is on the same channel incase the devices are needed.

The uses of other 2 way radios, such as cell phones, are more obvious. Car problems while out on the highway can be a major issue unless you have a cell phone to keep you in contact with the outside world. In addition, landline phones often have problems and may be out of service temporarily. In many of these instances, however, cell phones are still operational and can offer a way to report the outage to phone companies, stay in touch with family and friends or make emergency calls if needed.

There are a number of places to find 2 way radios, including retail and specialty stores. The internet is also a wonderful way to find 2 way radios in a variety of styles, features and price ranges. Most electronics feature a manufacturer's warranty when purchased new, so take note of any such offerings when browsing for 2 way radios. Warranties often last for 90 days to one year and cover repairs and/or replacements of any product that is defective as a result of workmanship or materials. It is best to keep any warranty information tucked away in a safe place for later retrieval.

As a final thought with 2 way radios, it is best to test the product before putting it to actual use. In other words, the best way to test a walkie talkie is not when you are already out on a camping trip. The best time would be before you leave home and always be sure to test the distance at which you can still communicate without any problem.

Onstar Satellite System For Engine Efficiency

Writen by Lance Winslow

OnStar is a cool system for any family. There is even the ability to unlock your door from Space, no kidding, so if you lock yourself out of your car you simply call a number and they unlock it from space. With this great technology and the fact it always knows where you are with GPS, that means the OnStar system could do much more, if it were designed to do so.

Recently a friend on a road trip in a mini-van had been thinking that when going up and down hills the engine had a tough time at the higher altitudes. Having Onstar of course makes drivers feel safer when traveling on road trips; for instance if you get caught in a snow bank collapse or small avalanche. As more people get GPS in their vehicles it will adjust traffic thru an area due to how the display is set on everyone's in car navigational devices.

Some GPS units suggest best routings and distances, by doing this on the more advanced units it will change traffic flows, for those who have such units. The programmer in Los Angeles could end up effecting traffic in Wyoming on a Device made in China sold with your German car. Go Figure? Currently not all GPS Navigational Systems are programmable and those which are, well like your home VCR, you may never figure out how to use all these cool options. It might be easier to learn a new language?

My friend said; "Wouldn't it be cool if the Onstar had the capability of programming ones itinerary into an onboard computer, which would then program the engine to be more efficient?"

Well with GIS information data sets figured into the GPS Navigational system it would be easy. The XML database sets can be integrated that is not a problem. Then the Onstar could tell the navigational system that the elevation is changing for a hill. The engine would change for fuel setting for a lower gear or passing gear as the driver hit was one-third up the hill. The GIS-GPS system would tell satellite where it was and the satellite would tell the car that you were at higher altitude and to lean out the mixture of gas and air. Sure, I agree this would be a fuel efficient way to increase fuel mileage and performance and it is not only a smart idea, but also easy to engineer.

I can tell you I have my generator in my motor coach set for about 1500 feet and when I am up at 7-8000' it runs with extra soot coming out. It does not adjust properly itself. If Onstar adjusted for hills or down hill too that would be smart, it can be done, you know? My friend is correct, as it makes a lot of sense. Think on it.

Gps Never Ending Improvements

Writen by Simon Wyryzowski

When you purchase a GPS system, depending on the model and configuration settings out of the box, you will get a host of life changing utilities that will make your life easier and save you time and money everyday.

However, although the benefits out of the box are tremendous, the true value comes from repeated use and adding your own configurations, shortcuts, etc.

The more you customize the GPS unit to meet your needs, the more it "learns" about your preferences and requirements. You can add restaurants, stores, and anything you find during your travels that are not updated yet within the map systems.

Keep in mind that although not all data is one hundred percent accurate/updated all the time. That is is always accurate enough to improve your driving and traveling efficiency. In other words, having something that is accurate 90-99 percent of the time is better than not having the tool at all.

It's something that will stay with you all the time too while you are on the road for business or while on a vacation. It almost gives your vehicle an artificial intelligence dashboard that answers to you, the captain of the ship, and provides valuable support and insights so you can focus on the important thing- getting to your destination.

Car tracking device features will enable you to keep a close eye on your automobiles automatically.

How Location Based Services Are Misused

Writen by William Alexander

The Global Positions System (GPS) satellites are free for anyone to use. However, to use it, a GPS receiver is required which is not free. In recent years these GPS receivers have become very small and embedded in mobile phones. This has given rise to many location based services. Though there are many LBS applications that are very useful, there are a few applications that are misused.

One of the location-based services as mentioned at http://www.m-indya.com is Child Tracking. In a study carried out by New Media Technologies students (2005) in Australia, they have detailed how this service can be misused. They state that,

"In 1998 the US implemented the Children's Online Privacy Protection Act 1998 which limits the ways Web site operators and others may collect and disseminate information pertaining to customers under the age of 13. So far, Australia has not followed suit and does not seem to have a law, which directly protects children from technology such as the Internet. With the introduction of global positioning systems for tracking purposes, the issue of child protection needs to be addressed before this technology gets into the wrong hands and used for malicious purposes."

Some of the other consequences that may occur due to these services are the problem of parent-child relationship and also marital relationship. In their study they point out "parents should negotiate with their teenagers an agreeable form of knowing where they are whether it be GPS on their phone or just a phone call to let them know where they are. This will ensure that the relationship will not be damaged through a form of mistrust."

And even between spouses each needs a bit of their own space and privacy, which will be jeopardised by the use of this service and may cause problems in marital relationships.

In a ZDNet news by Lisa Bowman (1999) speaks of some scary scenarios where this technology can be misused such as, "Insurance companies could refuse to insure you, or charge you higher rates, unless you install a tracking system on your car. They could then tell if you drive over 55 or spend time in shady neighbourhoods where your car has a greater chance of being stolen." Or "FBI and local police officials could have access to your whereabouts by simply logging onto a database attached to a cell phone, tollbooth or GPS tracker".

In yet another case a rental car company was sued by the customer for tracking him down using GPS. "In a case that could help set the bar for the amount of privacy drivers of rental cars can expect, a Connecticut man is suing a local rental company, Acme Rent-a-Car, after it used GPS (Global Positioning System) technology to track him and then fined him $450 for speeding three times." (Robert Lemos, 2001).

A Wireless week (2003) article lists how even location based games can be misused. "In Sweden, thousands of wireless game subscribers stalk each other using cell phones and location technology. In Japan, you can use a GPS-enabled cell phone to arrange a date, an application sometimes used by teenage prostitutes. In many countries around the world, a GPS-based game called "geocaching" is growing in popularity." Ever since Princess Diana's death the perils of stalking has come to the forefront in the media. The availability of such services will only help the stalkers.

As if these are not enough there are other privacy issues related to location based services. If you need further reference visit the website http://www.m-indya.com

What You Need To Know About Xm Satellite Radio

Writen by Jim Johnson

Satellite radio is catching on like wildfire these days and as more consumers actually gain experience with it, they come to appreciate it's benefits and get on board with this new technology. There are two main satellite radio service providers and they are Sirius and XM, but for this article let's just focus on what you need to know about XM satellite radio.

First of all, satellite radio is a new way of broadcasting radio signals that eliminates most of the problems and shortcomings of standard radio broadcasts. For instance, haven't you found it annoying that after you travel about 30 - 50 miles across country, you have to change the radio station because the one you are listening to fades out and becomes unlistenable? Well, satellite radio solves that problem as the radio signal is recorded digitally and transmitted to satellites that orbit the earth high in the atmosphere. Since there are no obstacles or obstructions between them and the listeners here on the ground, you can literally travel from coast to coast and keep listening to the same radio station as you do.

XM radio offers over 100 channels of radio programming too that runs the gamut from every kind of music you can imagine, to talk radio, sports programming, and much more. You can always find something good to listen to on XM radio, and they keep adding even more popular programming content as they go on. For instance, XM has recently added a channel called "Oprah & Friends" that will feature Oprah herself and many of the popular personalities from her show. They have also brought Bob Dylan on board to host a weekly show for music fans across the country. And more of this kind of original programming can be expected to arrive on XM in the near future.

One of the big advantages of XM satellite radio though is the ability to listen to it generally free of commercial interruptions. Because it is a subscription based service, there is no need to sell on-air advertising, and that simply means that listeners get more of what they really want, the programming that they signed up for. The service is very inexpensive at only $9.95 a month, so it's affordable by almost everyone.

You will have to purchase the receiving equipment necessary to decode the radio signal, in order to listen to it, but there is a wide array of electronics products that cater to XM radio. You can find units specifically made for your car, your home stereo, and even those that can be switched back and forth whenever you want. In fact, XM is also leading the industry by providing portable units from Samsung and Pioneer that can play XM radio wherever you are and also play MP3s, WMA files, and even recorded XM content too.

So why not consider joining the almost 6 million subscribers that are currently already on board and enjoy the breakthrough radio broadcasting technology from XM satellite radio?

The Facts You Need To Know About Satellite Radio Part 2

Writen by Jim Johnson

In Part 1 of this report, we discussed how the technology of using satellites to broadcast radio signals from over 20,000 miles above the earth results in great reception throughout the US everywhere and all the time. But there is more.

Satellite radio is not free radio. It is subscription based, meaning that you pay a monthly fee for the service. The costs are very nominal though as Sirius costs $12.95 a month and XM is $9.95 a month. Neither of the subsciptions can be said to be expensive, but initially you may recoil from thwe idea of paying for something that you have gotten for free for so many years.

However, think about this. You weren't actually getting anything for free all this time. Think of how much time in your life has been wasted listening to ads or commercials on the radio instead of the programming that you tune in for. If you added it all up, it would no doubt be a huge chunk of time, and if your time is worth anything, you were definitely paying a price for tuning in. The radio stations have no other way of making radio broadcasting a profitable business, so you are stuck with putting up with ads for so many minutes of every hour just to be able to listen to the programming you want in between the commercials.

Satellite radio is following the proven business model example of cable television and instead of inundating you with ads, they just provide high quality programming all the time. No ads, no commercials, no wasting your time.

And what kind of programming do you get? Just about anything that you can imagine, and it's growing all the time. Your selections include music, talk radio, sporting events, kids programs, news and more. There are several celebrities that have set up shop in the studios of the satellite radio companies, including the high profile case of Howard Stern. But you can find even more celebrity specific programming from others like Martha Stewart, Jimmy Buffet, Eminem and more.

There are around 65 channels of music listening alone on each provider's service, and they cover almost every conceivable kind of music that is found in the US including rock, jazz, country, blues, reggae, and more. And there are several different kinds of each music genre as well, For instance, rock has channels devoted to hard rock, early rock, soft rock, heavy metal, and many more. Just pick your favorites and tune in for solid good music that you like to listen to wherever you go.

Be sure to read Part 3 for even more satellite radio facts.

An Overview Of Gps Systems

Writen by Chris Simons

GPS stands for global positioning system, a system that has been established and is managed by the Department of Defense. The GPS system utilizes satellites that have been put into orbit that help people determine their exact location whether it be for the purposes of personal navigation, military activities, or any type of enterprise that requires an exact global positioning by latitude, longitude and altitude. GPS systems are installed in automobiles, motorcycles, some PDAs, Airplanes, dog collars, fishing boats, and so many other products.

GPS systems all started out in the army in the year 1970. In the army, many soldiers needed navigation systems to know their directions around other countries. Without this device it would be really hard for them to find their way around. This device has saved soldier's time in war and has also saved many lives. GPS systems are very powerful devices and are a great navigation system to use to get around.

GPS systems have gone for beyond just serving the army. They now serve just about everyone. These navigation systems help drivers find there way through city streets and help hikers find their way through the rough terrains of the mountains. They also help pilots find their way around the skies as well as helping mariners find their way around the great sea. The GPS systems technology can help serve anyone in need of it. GPS systems can also be purchased for motorcycles, and hikers sometimes use such systems to determine where they are while walking. Cyclists should not be left out of the mix, and runners, joggers, and skiers use navigation systems to prevent themselves from becoming lost in an unfamiliar area. Some PDAs - personal digital assistants - are equipped with built in navigation devices, while some Palm devices also include such systems.

Navigation systems are sold with a variety of features and what kind of features you should look for is solely dependent on two factors - price and need. The most basic of navigation systems will provide you with a route from one point to another point or to multiple points, depending on your destination and trip plan. A benefit of such navigation systems is that they not only serve as a guide to your preplanned destination, they also serve as guide back to where you started. Any route you plan in a navigation system is completely reversible thanks to the innovative design of such systems.

Alternatively, you may pay more money for a navigation system that has voice capabilities. You can purchase a navigation system that will guide you to your destination vocally and while speaking to you it will offer up a turn-by-turn dictation of your journey. Conversely, those individuals that spend the majority of their time traveling - like a delivery man may find that they prefer a navigation system that they can preplan many destinations at one time and then move from one set of directions to another. Thus, such individuals require a uniquely designed navigation system -one that possesses multi destination capabilities. Finally, there are different navigation systems for boats, motorcycles, cars, and joggers so you will need to be sure to purchase the product you require for your intended use. The most popular GPS Systems are made by: Navstar, Magellan, Garmin, Slim Trak, Cobra, Holux, Suunto USA, and Timex.

Most Electronics Stores Offer Great Deals To Those Who Buy Digital Radio Receivers

Writen by Keith Londrie

Satellite radio still has not caught on in the United States of America. Despite the hundreds of channels XM Satellite Radio and Sirius Satellite Radio offer, there are still two major drawbacks. The first is that someone who would want to buy digital radio equipment will have to pay for an expensive receiver and will also have to pay a monthly subscription fee. It is yet to be seen if satellite radio will catch on in the United States. I predict that the monthly subscription fees will also come down and be more in line with a traditional reciever.

Secondly, while it is great for some people that the stations are exactly the same everywhere in the country, many people like some variety to their music and will want to hear a different disk jockey playing different sets of songs instead of the same guy day after day. Even though you have hundreds of stations to choose from, chances are they will only be playing certain songs over and over. Despite the setbacks, in an attempt to drum up business for the satellite companies, electronics retailers like Best Buy and Circuit City offer great deals to those in the market to buy digital radio receivers. And these deals will get even "sweeter" as the retailers embrace innovative new markeing tactics.

Someone looking to buy digital radio receivers from XM Satellite Radio's store for example will actually have to try to pay full price. At XM's own digital radio receiver store, prices are slashed all over the place. Almost every receiver, including the incredibly popular Delphi SkyFi 2, contains tons of mail in rebate offers. XM is also offering special deals on bundle packages so people can enjoy purchasing the receiver, a car kit and a home audio kit all in one package for less than the manufacturer's suggested retail price of just the receiver.

The otherwise very pricy Delphi MyFi portable receiver is slashed even more with XM's store offering the regular $225 US item to customers for only $175 US. These amazing deals are offered in a way to make people forget about the monthly fee associated with satellite radio subscription. For those looking to buy digital radio listening equipment, almost any store you visit will have excellent markdowns on receiver products. The nature of having a montly subscription fee warrants the lower prices on recievers. This is probably the only way in which the retailers are able to sell these recievers.

Xm Satellite Radio Has One And Now So Does Sirius The Unveiling Of The Sirius Starmate

Writen by Scott Fish

Note: Author is not associated with Sirius or Howard Stern in any way and this article is meant to be an analysis of the move to Sirius Satellite Radio by Howard Stern and events surrounding it.

Sirius unveiled its new Portable Satellite Radio Digital Player Combo recently. Now you can record and use the playback function in your car! Weighing in at less than 4 ounces, the Starmate replay is only 5 inches by 1.9 inches and allows recording of up to 44 minutes of Sirius Satellite Radio Programming. The new product comes with a car mount and is available to consumers in October 2005 for a reasonable price of $129.99. In addition, an option home kit is available for $39.99 and allows users to record at their leisure in their own homes.

Sirius One, the new car radio which was also unveiled recently is the same size of the Starmate, but weighs 5 ounces and costs considerably less, $79.99, what a steal in comparison! The busy holiday season for Sirius is crucial for the company; they are banking on increased customer base and increase sales of their receivers and accessories. "The Starmate Replay and Sirius One offer an easy and inexpensive way to get Sirius," said Bob Law, senior vice president and general manager of Sirius's Consumer Electronics Division.

Sirius reported to have 1.8 million subscribers and they are looking to increase this base dramatically. Its only real rival, XM Satellite Radio Holdings Inc reported 4.4 million subscrivers during the second quarter of this year. Both companies are strongly pushing advertising and are expected to take a huge advantage of the holiday season in order to increase sales and subscriber base.

Gps Trackers And Their Most Popular Uses

Writen by Chris Simons

GPS became available in the 1980's. For a long time the technology was only used by the military. It then became popular as a tracking system in cars. GPS Trackers are used for a variety of purposes, such as in cars, trucks and cell phones. Companies that have a large fleet of vehicles, such as a trucking companies or taxi cab and limousine services use GPS to track the locations of their drivers. They are also used as a safety precaution in the event that one of their vehicles is stolen or if a driver radios in that they are hurt or in danger, the problem of figuring out their location will be eliminated. The most common consumer use of GPS tracking systems is seen in automobile digital maps - a good resource for planning trips or helping drivers find new places without getting lost.

The use of GPS trackers is not limited to digital automobile street maps. GPS trackers are now being anonymously used to track a people. This is especially popular in families where a teenager drives the family car, and the teenager is suspected of doing things or going places they have been told not to go.

Choosing a GPS tracking system can often be overwhelming. Google's directory lists over 200 companies that provide GPS systems. Here are some brand names to consider when buying a GPS unit: Garmin, Navam, Magellan, Tele Type, Rocky Mountain Tracking, GPS Tracker. Many popular cell phone brands now have GPS functionalities built in.

Science is also beginning to use GPS trackers as a way to help conduct experiments and learn more about animal movements. Researchers can put collars with GPS trackers on nearly any kind of animal ranging from a bear to a mountain goat. Dog owners are also starting to buy dog collars with GPS trackers built in, to make it easy to find their pet in the event it gets lost, stolen or runs away. They are also being used as safety devices to track young children and even older patients suffering from Alzheimer's and other similar physically disorienting diseases. Even the GPS built into cell phones come in handy in search and rescue missions for emergency personnel, who can use a GPS tracking device to locate anyone whose cell phone has GPS built in.

Gps What Is It

Writen by Michael Russell

GPS, or Global Positioning System, is the latest thing in keeping from getting lost when trekking out to visit your Aunt Louise. Years ago you had to rely on landmarks, your handy compass or the guy at the corner gas station, assuming he knew where everything was. Today for about a hundred bucks you can get a little gadget that will tell you exactly where you are, any place on Earth. By using some basic mathematical calculations and a rather complex system, you can be in the middle of the desert, lost as can be, push a button and have your GPS tell you exactly where you are so that you can hopefully find your way back home.

So what exactly is GPS and how does it work?

GPS is actually a very complex and expensive system but the fundamental concepts of the system are very simple.

The GPS system is a group of 27 Earth orbiting satellites. Twenty-four of them are in operation and 3 are backups in case one fails. The system was originally created for the US military but was eventually opened up to everyone else.

Each one of these satellites, weighing in at about 4,000 pounds, circles the Earth at about 12,000 miles per hour and makes 2 complete rotations everyday. The orbits are arranged so that at any one point in the day 4 of these satellites are visible from any place on Earth.

The complimenting receiver that was created to receive signals from these satellites has the job of locating 4 or more of these satellites, figure out the distance to each and from that information determine where on the planet the receiver itself is located. It then transmits this location back to the person who happens to be in possession of the receiver. The operation is based on a simple mathematical principal called trilateration. To simply explain how this works, let's say someone tells you that you are 10 miles from Newark, NJ, another person tells you that you are 15 miles from Maplewood, NJ and a third person tells you that you are 20 miles from Woodbridge, NJ. By taking those three facts you can figure out exactly where you are because each radius of each distance when linked together will intersect at only one point. That point is where you are located.

In order to actually do the calculation from space the GPS receiver needs to know 2 things. The location of at least 3 satellites above you and the distance between you and each of those satellites. The reason that only 3 satellites or spheres are needed is because the Earth itself can act as a fourth sphere. The GPS receiver itself works by radio waves which are a kind of electromagnetic energy and travel at the speed of light The receiver can actually figure out how far the signal has travelled by timing how long it took for the signal to arrive from each of the satellites.

In the next article on GPS we'll go over exactly how this system works to measure distance.

The Future Of New York Radio Howard Stern Sirius Style

Writen by Scott Fish

Note: Author is not associated with Sirius or Howard Stern in any way and this article is meant to be an analysis of the move to Sirius Satellite Radio by Howard Stern and events surrounding it.

Howard Stern's move to Sirius Satellite Radio will really make a huge difference for New York Radio. With listeners making the move to Satellite Radio and away from New York City, what will happen to the radio stations broadcasting in New York City? Does radio continue on a good course or does it need a wake up call? – Is this it's wakeup call?

The Daily News, has said that New York City radio "faces its last great wakeup call" and is being forced to deal with changing technologies, and the ever changing consumer tastes. The biggest threat, obviously to New York Radio is the changing of radio formats, from terrestrial to Satellite Radio. The Hollywood Reporter has outlined several new changes that Sirius Satellite Radio has made to its radio channel line up in order to take away market share from New York Radio and this is a huge threat to the terrestrial format.

Howard Stern isn't the only one whom is making the move to Satellite Radio, there are several shock jocks that are in some areas, the flag ship of Clear Channel and several other networks. Stern will now have two stations via Sirius Satellite Radio and there are more in the works. Sirius also has plans for upto five family and kids channels as well as three difference Christian channels. Sirius is covering all its listeners wants and desires, New York radio has failed to do that, and Sirius is answering the call of its subscribers for better content!

Gps Know Your Exact Position Anywhere In The World

Writen by Sharon Albright

GPS [global positioning system] is a worldwide radio-navigation system formed from the constellation of 24 satellites and their ground stations. It is a system mainly used to locate the user's position at a time. Although GPS was originally intended for military applications, but now it is mainly used in marine, location-based services and terrestrial navigation. GPS can work for 24 hours in any type of weather condition, irrespective of sun and rain.

Working of GPS system

GPS works in a wonderful way. The GPS satellite circles the earth twice a day in a precise orbit and transmits signal information to earth. GPS receivers take into this information and use "triangulation method" to calculate the user's exact location. The meaning of "triangulation" is receiving radio signals from a distance. Along with knowing the distance, you also need to know exactly the position of the satellites in space. This is done with the help of high orbits and carefully monitoring the instruments for locating the satellites. Finally you also need to correct any type of delays that the signal can experience as it has to travel for a long distance through the atmosphere.

Importance of GPS system

GPS is important as it helps you to figure out where you are and where you are going when you are traveling from one place to another. Navigation and positioning are important but cumbersome activities, which GPS makes it easier. Once GPS locates your position, then it starts tracing other factors like speed, bearing, tracks, trip distance, sunrise/sunset time, distance to destination and several other details. GPS uses "man-made" stars as reference points to calculate positions accurate to a matter of meters. However, with recent forms of GPS you can make measurements much better than centimeter readings. So it is with the aid of GPS that you can give a unique and specified address to every square meter on the planet.

You can get GPS services without any subscription fees and set up charges. So these days GPS finds its way into cars, planes, boats, construction equipments, farm machinery, laptop computers and movie making gears.

Modern GPS systems

With the world advancing rapidly everyday, there are recently discovered Newer Garmin GPS receivers with WAAS [Wide Area Augmentation System] that can improve the quality and accuracy of location of any one at any time. Although no additional equipment is required, yet users get the advantage of Differential GPS [DGPS] to get correct signals within the distance of three to five meters. So use GPS systems to get the maximum benefits of modern technology.
