I am currently a AT&T subscriber and am thinking of switching my home service but don’t want to go the VoIP route. And does Verizon require a commitment?

I’ve been tasked with setting up our Emergency Operations/Command Center and need to determine the best phone system to have in place. We have 67 seats, what’s the best way to go about this?

I live in austrailia and i want me and my family to call each other whenever for free using voip. how can i do this? i don’t want to use skype or any other ip telephony program just voip.
I was told if i buy the same brand routers here and in lebanon and make virtual numbers then it would work is that true?

Whenever we hear the term “GPS”, what would instantly come to our minds is a digital device with maps and other features that tells us our exact location on this planet. But do you know that such a device is just one part of GPS? The device is called a GPS receiver, and while it is indeed an important GPS device, it is just a part of a very large and complex system that allows us to measure our exact location on earth.

The three-lettered term “GPS” stands for Global Positioning System. It is a satellite based navigation system that has the ability to measure an object’s precise location on earth. The system was developed by the United States’ Department of Defense (DOD) and was officially called in the US military as the NAVSTAR GPR (Navigation Signal Timing and Ranging Global Positioning System). It was intended to be used for military operations only but has been opened for civilian use since the 1980s.

The Global Positioning System is a very huge and complex system that can be divided into three segments: space, control, and user. The “space” segment of the GPS refers to its network of satellites that transmit the signals used for location identification. The “control” segment, on the other hand, refers to the various stations on earth that maintain and control the system. The “user” segment refers to the GPS receivers—the actual unit that we often mistake as the system.

SPACE

The “space” segment of the GPS is a constellation of 27 satellites that orbits the earth at some 12,000 miles above its surface. 24 of these satellites are in operation while the other 3 are on “standby” mode and will be used in case one fails. Each of the satellites orbits the earth twice in less than 24 hours, traveling at a speed of approximately 7,000 miles per hour.

Each of the satellite used in the GPS constellation weighs about 3,000 to 4,000 pounds. All of these satellites are solar-powered, although all have backup batteries onboard to be used in the absence of solar power (i.e., solar eclipse). Small rocket boosters are also used to keep the satellites flying on the correct path.

The signals being transmitted by the GPS satellites are low powered radio signals. These signals contain three different bits of information—a pseudorandom code, ephemeris data, and almanac data—that are deciphered by the GPS receiver to obtain a precise measure of its location. The pseudorandom code tells the receiver which satellite is transmitting the signal while the ephemeris data provides information about the satellite’s position. The almanac data, on the other hand, contains information like the status of the satellite, current date and time.

CONTROL

The “control” segment of the GPS refers to the various ground stations run by the US Department of Defense that controls various aspects of the system. In particular, these stations monitors the flight of the GPS satellites, synchronizes the satellite’s onboard atomic clocks, and uploads the data to be transmitted by the satellites.

USER

The “user” segment of the GPS refers to the GPS receivers, whether they are used for military or civilian purposes. The GPS receiver is basically an electronic device that picks up the signal transmitted by the satellites and uses the information on those signals to figure out its precise location. Now that sounds simple! In reality, however, this function is a lot more complex.

The GPS receiver actually needs two things for it to figure out its location. First, it needs information about the location of at least three GPS satellites. Then, it would need to measure the distance between it and each of the three GPS satellites. The first information can be deciphered from the signal transmitted by the satellites while the second can be obtained by measuring the speed at which the signal was received.

ALL IN ONE SYSTEM

Combining the space, control, and user segments, we have a Global Positioning System that can tell us about our precise location here on earth.

You see, the GPS is not just the GPS receiver alone. It is a very big system, and a very complex one at that. But because every other part of the system is well maintained by the Department of Defense, we will never have to worry about those parts. All we have to do is to secure a GPS receiver and in an instant, we’ll receive information about our current location and other things that the receiver may want us to know.

Have you ever wanted to find where an old friend is living is now?  Or have you ever wanted to find out whom your daughter is talking with?  Or maybe you just wanted to send a Thank You or Christmas card to a client, and all you have is their phone number?  Well, these are all reasons a reverse telephone lookup directory exists. 

My first time doing a reverse telephone search certainly was an eye opening experience.  Since the telephone number that I was searching was a wireless number I had no luck consulting White Pages or any other online public directory.  These directories are solely for the use of landline home and business numbers, which are a matter of public information.

So, after resigning myself to having no luck there I decided to try searching the phone number in the major search engines.  I typed the number in Google, MSN, and Yahoo.  All three directories came up with nothing in relation to that number.  So, the next thing I did was type “reverse cell phone lookup” in the search tool bars of these 3 search engines.  To my delight, I saw sites that offered a “free” cell phone search and figured my problem was solved.  But after going through 4 of these sites, I found out the search was “free”, but the results were not.  Feeling misled, I wasn’t about to trust the validity of their data.  So I moved on to my next step. 

I searched why I had to pay for information associated with cell phone numbers.  What I found is that these numbers are not considered public information.  This data is owned by the major wireless carriers like Verizon, Sprint, and Nextel.  You can’t access their phone directories, so the only way to retrieve this data is through one of the reputable online sites that resell this data.  Fortunately, if you are determined to get the data, the cost is about the same as a pizza and the information you’ll obtain is pretty extensive. You’ll be able to find the owner’s name, billing address, map location of the address, what cell phone carrier the owner uses, and a history of that cell phone number, including previous owners of the number, if any.  Also, many times you’ll be able to find out the owner’s age and occupation. 

This information is obtained is easily and virtually instantly.  Good online sites also offer a money back guarantee and operate customer service departments that are responsive to any questions or problems you may have. 

So, next time you find yourself in a position where you need to find out personal information about someone and all you have is a phone number to work with, you’ll know what your options are.  Doing a reverse telephone lookup with one of the few reliable and trustworthy online websites is an option increasingly more people are turning to as a great resource in searching cell phone numbers.  One of the best and most popular directories is referenced below.

Those GPS systems that tell you when to turn and stuff, do you just pay the couple hundred for the system and that’s it, or do you have to pay money per month for the satellite service? If you do, how much is it? Thanks!
