GIGABEAM called a Virginian telecommunication startup introduced a new technology called WiFiber. This is a wireless technology which is used for data transmission between two points. This is a true substitute for fiber technology. It is used now for high specific data transmission. It actually succeeded to sit on the place of fiber optics in our world. WiFiber operates in the 71-76, 81-86, and 92-95GHz frequencies to avoid interference and so that the signal is less impeded by light rain or fog than current high-speed wireless competitors. It also transmits in a tight beam to avoid overlap, but you still need a line of sight, so heavy rain can spoil your day. If conditions are right, though, GigaBeam's signal can make it for 10 miles, and is already shooting data from the Trump towers in NY and from a few other metro sites. Unfortunately, it's mainly for business links right now, since it's currently $30,000 for a set of radios (but that price should drop soon).But when we compare its price with fiber installation price it is less costly than other. And further improvement in WiFiber technology reduces its cost again. In earlier days WiFiber technology supports of data rate 1.25gbps only and now it is improves to 2.7gbps. Similarly these changes can be viewed in its ownership costs also. That means its overall costs reduced when technology improves.

WiFiber can be used in Local Area Network also. WiFiber in LAN will create WiFiber local loop. This concept is very important in LAN.WiFiber is a true substitute for optical fiber technology. Because, this can be used instead of optical fiber and it can transmit data at higher rate than fiber optics. Some of the other important features of this technology are:

•Full Duplex sustained GigE throughput (Layer 1, low latency, all jumbo frames including 64KB).
Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second, as defined by the IEEE 802.3-2008 standard. Half-duplex gigabit links connected through hubs are allowed by the specification but in the marketplace full-duplex with switches are normal.

•Typical one mile transmission at 99.999% weather availability.
Using this technology we can transmit data up to 1 mile without depending upon the environmental conditions. In the arid conditions we can transmit data maximum up to 10 miles.

•High reliability design with dual input/internally redundant power supplies
Redundancy is the duplication of critical components of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe. This makes the WiFiber better in data transmission.
