In communications history, there was a big buzz when analog technology was invented. People were so excited with this new invention that it started the new age of communications. We can now hear our loved ones who are thousands of miles away through the humble analog telephone. Then occurred the advancement of digital technology. Contrary to analog which takes an audio or video message and turns it into electronic pulses, 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.

Since the humble telephone, communications technology has come a long way. Technology is now gearing towards wireless communications, rather than wired technology. Expressed 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 set up 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 only body that orders these transmission frequencies is the International Electrotechnical Commission or the United States’ FDA. Your wireless signal is good as sent as long as the radiated power cannot exceed the constraints determined by the IEC. 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 accommodate wires or cables. This comprises 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.

To maximize the power of wireless technology, it needs a little extra help from fiber optics itself. Fiber optic transceiver modules may be used to connect the Uplink/Downlink equipment to the transmission towers. This greatly adds 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. It is positive that telecommunications technology really depends on a glass or plastic fiber that sends light along its path, whether wired or wireless. Fiber optics technology is sure to remain valuable in the advancement of how the world will communicate.
