The Links With Fiber Optics And Wireless Communications

In communications history, there was a big news when analog technology was conceived. People were so happy with this new development that it pioneered the new era of communications. We can now listen our family and friends who are hundred of miles away through the unassuming analog telephone. Then came the development of digital technology. Digital breaks the signal into a binary format where the audio or video message is corresponds to a series of "1"s and "0"s in comparison with analog which takes an audio or video signal and converts it into electronic pulses.

Since the humble telephone, communications technology has come a long way. Rather than wired technology, technology is now gearing towards wireless communications. Defined by IEEE standard 8.02.11, wireless refers to the telecommunications technology, in which radio waves and microwaves carry signals to connect communications devices. These devices include pagers, cell phones, portable PCs, computer networks, GPS, satellite systems and handheld personal digtal assistants (PDAs). The idea that a network detached from wire with a transmission scheme that consists of voice and data quickly whizzing through the air from point A to point B is quite something.

The need to develop wireless networks lies in the ease of installation, and the rapidity of its technological advances. Wireless technology permits a network to go practically anywhere without having to install cables and wires under the streets. On top of this, over-air wireless transmission is free because wireless fiber optics uses the 300 GHz spectrum and above, which includes infrared frequencies, a range that remains unlicensed. The International Electrotechnical Commission or the United States' FDA is the only body that regulates these transmission frequencies. On the condition that the radiated power doesn't go above the constraints set up by the IEC, your wireless data is good as sent. It will not be long when the United States is expected to adopt the IEC standard, creating a global wireless transmission standard.

Wireless technology is widespread where local area network (LAN) can't hold wires or cables. This includes the following: (1) Last-Mile Access: High-speed links that connect end-users with Internet Service Providers or Satellite services, (2) Metropolitan Area Network extensions: Use to connect new networks, their core infrastracture, to complete, (3) Enterprise Connectivity: Use to connect LAN segments housed within buildings that do not have easily accessible right-of-ways for fiber, (4) Fiber Backup: Act as a backup for a fiber based system, (5) Backhaul: Wireless sytem used to carry cellular phone traffic from antenna tower back to facilities wired into the public switch telephone, and (6) Service Acceleration: Use to provide instant service to fiber optic customers while the fiber infrastracture is being laid.

Wireless technology requires a little extra help from fiber optics itself to make the best out of its power. Fiber optic transceiver modules may be used to connect the Uplink/Downlink equipment to the transmission towers. This greatly increases the distance between the base station and the wireless transmission towers. By incorporating fiber optic links such as Ethernet converters, the system's EMI sensitivity is greatly reduced while reliability and signal quality is increased.

From analog to digital, these technologies greatly depend on wires and cables to send your message to the other end. And whether wired or wireless, it is certain that telecommunications technology deeply relies on a glass or plastic fiber that transmits light along its way. Fiber optics technology is certain to stay invaluable in the developement of how the world will communicate.
