Fiber optic technology

Fiber optic is transmission data transfer which made from glasses or plastic. It’s shape very small and this tool can transfer light signal.  The technology development very good, can bring out side this technology. The speed of transfer use fiber optic very fast, because it is made from plastic or glasses, so that the light signal if want spring back, will be back again, so there is no lose signal. The light from fiber optic will not go outside because drift index from glasses is bigger than drift index from air. So, fiber optic technology is very good for use as street communicate.

In principle, fiber optic spring back and extend in there. The light in the fiber optic will bring the data from one place to another place. And this technology has been there from for years ago, people have known about this technology. But this technology is not use. For the first generation, the system of fiber optic still simple and can be base for the next generation. The second generation, this fiber optic have capacity of speed ten times bigger than the first generation. For the next generation, it happened complete for that capacity of transmission and fiber optic always get some development.

Wireless Evolution

Your phone has been equipped with Wi-Fi? Of course, almost all new telecommunications products output is its Wi-Fi facilities. With this facility you can be accessible to the internet without having to spend your credits; you just need to find a place that it’s Wi-Fi available. 

But do you ever think about the evolution of wireless access technology based on this? This technology is initiated from PSTN or ISDN evolved into a home phone that is still based wire line and then headed to the DSL as a broadband communication anticipation, while wireless technology has evolved from first generation (1G) is analogue to a digital 2G systems to fame with GSM (Global System for Mobile ) evolved into the GPRS (General Packet Radio System), then spreads to the 3G (W-CDMA) with a technology known as UMTS (Universal Mobile Telecommunications System), then to the HSDPA (High Speed Downlink Packet Access) and LTE (Long Term Evolution) . Last one or LTE technology is still evolving toward the target Advance LTE (4G). This is the future of network technology, let's wait how the application.

Implementation of Wi-Fi technology

Current network technology has grown rapidly. Various technologies have been developed to assist humans in communicating. If we remember the era of 80-year, computer networking technologies rely on cable based network technologies, but currently the technology started many left because of some limitations, such as the costs which must be issued by the company when using this technology (wired network), besides that this technology is also not flexible because it is very dependent on the cable. You can imagine how many millions of feet of cable will be used to transmit data from one island to another island. It is a waste of time and inefficient.

Currently, if we consider as companies begin implementing wireless technology (wireless) or commonly called the Wireless Fidelity (Wi-Fi). This we can see there are many companies now that offer hotspot areas (areas that have Wi-Fi based Internet network) which can be accessed by everyone whether for free or by way of registration to the service provider.
