Its wireless communication system.
Was Morse code used in World War I?
Morse Code requires less transmitter power and/or a less sensitive receiver to successfully send a given signal over a given path both of which can be an advantage, for example in mobile communications. Conversely, for the same transmitter power and receiver sensitivity, a Morse Code signal may be sent successively over a longer distance or under noisier conditions, for example when "Jamming" is in use. Finally, with the technology available in WWII it was much easier to send encrypted messages with Morse Code, since voice scramblers and computers were generally unavailable. That is, all that was necessary was to encode a text message with some encryption scheme, often by hand, and send the encrypted characters otherwise "in the clear" by Morse Code.
How do you transfer an att cell phone number to a land line?
Just call them up and ask for a number port. It's that simple :)
Hotel telephone call conversation about reservation?
good morning sir,is this is reception could u provide information about luxierious rooms in our hotel,and i would like to know about how much ur charging?
Who is the actress in the ATT dead zone commercial?
If you are referring to the scary neighbor lady, I thought she may be the actress who played Nina on the t.v. series "Just Shoot Me".
Can you track a cell phone from your PC?

Interference - If intermittent and difficult-to-diagnose wireless communication errors occur, interference might be the culprit.
What happened to the Morse code operators when the telephone was invented?
First of all; It would be "What happened after Morse code was invented" and Second of all; do your own stupid work.
Morse Code provides a letter-based method of communication by means of any type of signal that can be switched on and off ... light, sound, etc. As such, it can accomodate messages in any language that uses the familiar Roman (English) alphabet. While using the simplest possible transmitting and receiving equipment, it is highly immune to noise, and can succeed over very noisy 'channels'.
How can you use your ATT SIM card in a tracfone?
"first you have to read your sim serial number remember that or write it down. now go to tools scroll all the way down and go to sim app ignore all that stuff that pops up and put in the last 8 digits of your sim serial number. if that doesnt work i cant help you.
it worked for me."
Nobody reports this as being potentially successful, and members of Tracphone discussion groups are unaware of this workaround.
In reality, TF chaingangs the SIM to that phone and the provider they choose in that locality, by zip code. SIM swaps, porting, even transfer of minutes and air time usually involve inputting codes into the phone given by Customer Service, and the first level of Customer Service usually follows a scripted pattern which too often does not resolve all the issues. If you have more than 1100 minutes to move, it will have to be elevated to another supervisory level.
TF does this because the phones are so inexpensive that resellers could basically purchase a significant number and then jailbreak them, eliminating their future profit selling their airtime. In most cases, the phones aren't leading edge technology - usually old models from manufacturers that are middle of the road in features. Buying a new one is cheaper than investing the average wage in hours it takes to get it done.
For example, a $40 purchase will get you a Double Minutes For Life phone, under $20, and a $19.99, 60 minute, 90 day airtime card. Combined with the start up minutes and time, you net 140 minutes, and 150 days air time. Two phone purchases a year totalling $80 just about cover all you need. 3G service runs $75 a month in comparison - on contract.
Tracphone leases airtime from ALL the major providers, Tracphone users rarely hang on long enough while moving to transition from one to another. It's a pay as you go phone service, not an unlimited plan. Treated that way, it's quite successful.
Considering the huge difference in service and models available, there really is no point in jailbreaking a Tracphone. It's like stealing an old used Yugo, it's practically it's own punishment.
Name an application of the total internally reflected of light in the world of telecommunication?
It allows fibre optic cables to work thus transferring data over huge distances very quickly. That said it's not perfect and the signal strength still needs to be boosted at set intervals depending on the quality of the cable.
What is the evolution of data communication?
The 1970s and 1980s saw a merger of the fields of computer science and data communication which has profoundly changed the technology and products . The revolutionary merger has resulted in a new combined computer communication industry.
What is a telephone communication service provider?
It is a company that offers phone services either residential or commercially. They provide local calling and can offer long distance calling as well. They are usually called phone service providers.
When was the World Wide Web first introduced?
I'm not sure exactly how the web was created, but you might want to try going to www.greatachievements.org for some help. I hope that helps!
AnswerThe Internet itself began in the 1960's as a Defense Advanced Research Projects Agency development intended to allow universities and research facilities to communicate and share data. Email, newsgroups, and file transfers were it's primary uses. In 1990, hypertext was developed for use on the Internet, as well as the first browser, with the first web page being published in December of that year. So that would technically mark the beginning of the WWW, but at that time use of the Internet was still restricted to the US government, universities, and other research facilities. In April of 1993, the Internet was released for public/commercial use.Answer
The internet was available prior to 1993 - I used it myself in1975 (at 300 baud over an accoustic coupling - slow!), but you had to use ftp and other 'technical' commands to do stuff. The hypertext protocol developed at Cern allowed simple interaction and linking to take place. Incidently, the DARPA project was more to allow the military to keep computers talking via multiple network paths for resilience in time of war, rather than to facilitate university research collaboration.
What are the att uverce remote control code for dynex tv?
Hope this helps anyone like myself that was trying to set the remote codes on a Yamaha Receiver remote for a Dynex TV. I have a 32" Dynex in a second viewing area that I wanted to control with the RAV367 remote from my Yamaha RX-V1800 AV Receiver. I went through dozens of codes gathered from numerous websites, all with no luck. I finally decided to try programing it directly remote to remote with Yamaha's "Programing codes from other remote controls" chapter on page 104 of the RX-V1800's owner's manual. To my delight it worked perfectly and I now have most of the remote commands I use most often. The only alteration I made was to use the "TV Mute" control button on the RAV367 to set the TV input from the Dynex remote while using the "TV Input" button on the RAV367 to control the HDMI input. Other than that slight alteration every function I normally used on the Dynex remote I can now control with the Yamaha remote. I hope this helps.

What is wireless communication media?
Wired transmission media is media used to transfer information over a network, such as Twisted Pair cable. This is opposed to wireless transmission media which uses radio waves to transmit information. There are many types of wired transmission media such as coaxial cable, telephone lines, etc. Basically any form of wire used to transmit information over a network is considered a wired transmission media.
What kind of telephone line do you need for DSL?
Any standard phone line will do. My daughter lives in a house with 50-year old wiring, and her DSL works fine. What is really important is how close you are to a call center. That is a cenral routing station, owned and operated by the phone company. If you live further than 1/2 mile, the service degrades proportionally. One good way to find out if you are close to one is to go to say, SBC, (or your phone provider) and apply for DSL service. Before you commit, they will analyze your phone number and tell you if you qualify.
What is the major factor that makes coaxial cable less susceptible to noise than twisted-pair cable?
A coaxial cable is shielded from electrical interference signals whereas UTP (Unshielded Twisted Pair) cable is not. The random twisting with which UTP is manufactured works very well, however, in locations where the interference levels are relatively low, because its method of construction ensures that any interference affects both wires in the pair equally. It should also be mentioned that STP (Shielded Twisted pair) cable is also available and is sometimes specified for LANs (Local Area Networks) instead of coaxial cable. But the much greater volume of coaxial cable sold means that coaxial cable prices have been kept very competitive with STP. As STP tends to be more tricky to install - its shield has to be very carefully and correctly terminated at each end - coaxial tends to be used more than STP where noisier-than-normal interference conditions are present at a particular site. Since the 1990s NIC (Network Interface Card or Component) equipment has had extra logic cicuits within it to reject ambient interference much more effectively than equipment which was designed in the previous 20 years, so nowadays UTP can be used more extensively in locations where only STP or coaxial cable would have had to be used before. So, in relation to LANs in normal non-industrial office and domestic buildings, this exam question is now almost obsolete! However coaxial cable is still necessary to carry LANs in difficult environments such industrial plants; hospitals; undergound railway and road tunnels and mines; on board ships and aircraft, etc. and must also be used to carry signals for radio, televison, video and other applications which run at much high frequencies and bandwidths than LANs.
