Telecommunications
Telecommunications refer to the transmission of information over distances for the purpose of communication. In the modern age of electronics and electricity, telecommunication includes the use of electrical devices, radio and microwave communications, fiber optics, orbiting satellites and the Internet.

You don't need to connect wire between the wireless device it is easy to set than cable devices.
use anywhere with Wi-fi availability
use in any room in your house
What are military and mobile applications of Optical Fiber Communications?
optical fibre milatary applications
What was the second telephone?
hi guys the second telephone ever invented was the telephones for the deaf invented around 1880. then was the candlestick telephone invented in the year 1900. i hope that helps.
What is the difference between Telecommunication and Mobile communication?
the difference between Telecommunication and Mobile communication that , tele related to wire communication and mobile related to wireless communication
What is the range of laser communication?
There's no set limit, it depends on the power of the laser and the sensitivity of the receiver.
What are five major components of telecommunication system?
A communication system can be represented by the following flow:
Transmitter --------> Channel ---------> Receiver
The transmitter is input or source component. It is also responsible for any encoding of the information if applicable.
The channel is responsible to transfer the information from the source to the destination without distortion or loss of information. Channels tend to be affected by external signals or noise. To achieve this a variety of "protocols" or rules are used.
The receiver is the output or destination component. This responsible for receiving the message in the form transmitted, decode it if applicable and render the original information.
Where exactly is the Morse code in Wii Sports Resort Island Flyover?
There are three different messages which are cycled.
#1:
Morse code takes forever.
It sure does.
#2:
Does anyone out there know Morse code?
Sorry. Use your radio.
Yes, people are still chatting away in Morse code.
Check out http://www.arrl.org
#3:
Why does anyone use Morse code anymore?
Good question.
It's cheap and efficient. It gets
through in bad conditions. In fact some aviation
beacons are in morse.
The DB25 connector was designed by Bell Labs to connect a variety of different modems to terminals. At the time the phone company owned all the wires and everything that connected directly to them, thus they owned your phone and any modem you used with a terminal to connect to tymeshare services. The 25 pin cable that connected the DB25 (DCE) on the modem to the DB25 (DTE) on your terminal was owned by you. Thus the DB25 connector on the modem was the property line that allowed you access to use the phone line for digital data via a phone company owned modem. This was eventually standardized as RS-232.
It was your responsibility to set the DIP switches on your terminal to be compatible with the phone company owned modem that they supplied. The most common early modem was the 300 BAUD asynchronous full duplex modem but the 1200 BAUD asynchronous half duplex modem was also available. Both used the same DB25 but the half duplex modem used some additional wires for handshake to switch line direction, under control of the modem. There were also higher speed synchronous modems that generated clocks for your terminal, the clocks used more additional wires. All 25 pins are preassigned some modem related function in RS-232.
After the law was changed to allow third party devices to connect directly to the phone line, there was much innovation and much faster modems (most asynchronous full duplex). The DB25 was still usually used to connect to these modems but it no longer defined a property line, it was just the connectors on the cable. Eventually modem companies started making cards that plugged into desktop computers and the phone line plugged into the card, making the DB25 obsolete.
The DB25 and the RS-232 standard have been much misused, to connect all sorts of devices that are not modems to computers... who is the "modem" and who is the "terminal". These devices often use handshake lines in ways that are illegal by RS-232, or use lines that RS-232 reserves for special but rarely used modem functions.
Can you give me resume sample for electronics and telecommunication engineer?
Yes I can. Put your e-mail address on my message board and I'll send you a resume sample. senthil.ece89@gmail.com
How do you enter character on telephone keypad?
You can enter a character on a telephone keypad by depressing a number multiple times until the desired character is chosen. For example, to enter the letter B, you would need to press number 2 three times.
What are the advantages of wireless communications?
A: The advantage is that no wires are needed to communicate. Example printer to computer. Obviously there are some disadvantages the power output is very limited in range. Why because if not limited it may interfere with other hubs or worst stealing info with a receiver.
What you can do after degree in electronics and telecommunications?
You could go into teaching or you could get a job manufacturing circuits/circuit boards.
Original ASCII codes were 7 bit or 8 bit?
ASCII is a 7 bit code. There are many nonstandard extensions of ASCII to 8 or 9 bits by various computer companies.
ASCII was developed to replace the obsolete 6 bit BAUDOT teletype code and was never originally intended for use on computers.
What is last mile solution mean?
The last leg of providing connectivity from a PSTN operator, ISP owner or Cable TV operator to a customer. Also called "First Mile" from subscriber point of view. Traditionally it is done by copper wires, you may find that connects your old telephone set to nearest telephone exchange. Copper wires carry analog signals generated by telephone equipment, including fax machines. Analog technology is by nature a less precise signaling technology than digital technology. Increasing demand for information access it became a big question to reach the unreachable.
Most subscribers, however, log on to this network through copper lines with limited capacity. This creates a bottleneck for advancing technologies that increasingly require greater bandwidth. Last-mile technology represents a major remaining challenge because the cost of providing high-bandwidth services to individual subscribers in remote areas can be higher than the service provider would like. Laying wire and fiber optic cables is an expensive undertaking that can be environmentally demanding and require high maintenance. Wireless networks will eventually provide the solution. Existing last-mile solutions are:
* Plain Old Telephone Systems (POTS), fixed copper wire.
* ISDN, a somewhat faster technology than regular phone service. Not so popular.
* Digital Subscriber Line (DSL) (or ADSL) over existing telephone twisted pair lines. very popular
* cable and the Cable modem, for data, using the same installed coaxial cable that already is used for television
* wireless (WLL, Wi-fi, Wi-Max) and including satellite services such as Direct TV * Optical fiber and its transmission technologies, therefore FTTH/FTTB (fiber to the home/Fiber to the Building).

Can you put metro pcs service on a att phone?
Yes you can. The Samsung Infuse is a particular ATT favorite.
It is material made from extremely fine fibers of glass. It is used as a reinforcing agent for many polymer products; the resulting composite material, properly known as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), is called "fiberglass" in popular usage. Glassmakers throughout history have experimented with glass fibers, but mass manufacture of fiberglass was only made possible with the invention of finer machine tooling. What is commonly known as "fiberglass" today, however, was invented in 1938 by Russell Games Slayter of Owens-Corning as a material to be used as insulation. It is marketed under the trade name Fiberglas, which has become a genericized trademark. A somewhat similar, but more expensive technology used for applications requiring very high strength and low weight is the use ofcarbon fiber.
