Answer 1

From Wikipedia:

The term wireless is normally used to refer to any type of electrical or electronic operation which is accomplished without the use of a "hard wired" connection. Some of these operations may also be accomplished with the use of wires if desired, while others, such as long range communications, are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g., radio transmitters and receivers, remote controls, computer networks, network terminals, etc.) which use some form of energy (e.g.,radio frequency (RF), infrared light, laser light, visible light, acoustic energy, etc.) to transfer information without the use of wires.[1] Information is transferred in this manner over both short and long distances.

The term "wireless" should not be confused with the term "cordless", which is generally used to refer to powered electrical or electronic devices that are able to operate from a portable power source (e.g., a battery pack) without any cable or cord to limit the mobility of the cordless device through a connection to the mains power supply. It is interesting to note that some cordless devices, such as cordless telephones, are also wireless in the sense that information is transferred from the cordless telephone to the telephone's base unit via some type of wireless communications link. This has caused some disparity in the usage of the term "cordless", for example in Digital Enhanced Cordless Telecommunications.


Good Luck....

Answer 2

Be more specific...
How to apply devices that use this technology.....
or how to design such devices.....
If you want to design these devices better brush up on
FFT and Wave Physics.....along with VLSA and Data Packet algorithms
If you want to do like "Jack Bauer" on 24 then go buy a
"wireless technology" for dummies book

Answer 3

The term wireless technology is generally used for mobile IT equipment. It encompasses cellular telephones, personal digital assistants (PDA's), and wireless networking.

Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice and keyboards, satellite television and cordless telephones.

Answer 4

Go to a library or Google and start reading. You would do well to divide your research into segments, starting with Marconi and the radio.
- Radio
- Television
- Radar
- Sonar
- Cellular
- Satellite
- RFID
- Internet
- Laser guidance systems
- Laser weapons

How soon do you need to know "everything"?

Answer 5

there are are lots of different subjects in the field... go to community colleges they have open classes for students and non students to go to and listen/ ask questions. or just look up guides online. also a website that might help is:
