Introduction……
WiFiber is a wireless technology which is used for data transmission between two points.
It is used now for high specific data transmission.
WiFiber operates in the 71-76, 81-86, and 92-95GHz frequencies to avoid interference.
It also transmits in a tight beam to avoid overlap.
WiFiber technology supports of data rate 2.7 Gbps.
Why Wifiber…..?
As Optical Fiber lacks in:
(i) Price
(ii)Fragility
(iii)Affected by chemicals
(iv)Opaqueness
(v)Requires special skills
Almost all wireless technologies uses the data transmission frequency around or lesser than 5 GHz. Hence, there is a huge traffic forms in such a range.
We need a better and advanced technology which is capable of high data transmission and can be used in high specific delivery conditions.
Contd……
It exploits a different part of the electromagnetic spectrum.
GigaBeam spend less time routing data, and more time delivering it.
The tight beams of data having directional nature will rarely, if ever, cross each other's paths, data transmission can flow without interference.
Its Working…..
Full duplex & point to point line of sight.
Wireless transmitters that send traditional signals are made of silicon
It permits high-speed data rates, where molecules in the atmosphere absorb energy at certain frequencies.
It exploits those frequencies that are less susceptible to absorption by air and water molecules.
TECHNICAL & H/W Info…..
System: Frequency Range: 71-76 GHz
(paired with 81 ± 86 GHz.)

System Noise Figure: -7 dB.
Antenna: Size and Type: 2 ft (60 cm)
Weight: 37 lb (17 kg).
Gain: 50 dBi @ 73.5 GHz.
Beam widths: 0.4´ @ 73.5 GHz
Electrical: Input voltage range: -48 V DC 25%.
Power Consumption: 28 W.
Dual Power Supplies: Redundant, single or independency connected.
Operating Environment:
Operating temp. range: -33 to + 55 ºC.
Altitude: To 15,000 ft (4,500 m).
Humidity: to 95% non-condensing.
Application…..
Contd…..
Merits…..
Companies are using products developed for the E-band frequencies (71-76GHz, 81-86 GHz, 92-95 GHz)
Government Offices: Federal, State, and Local Department of Homeland Security
Enterprises and Businesses
Wireless Service Providers, both mobile and fixed network ( Wi-Fi , Wi -Max) operators
International Enterprises and Service Providers
Educational Institutions
Microwave Satellite technologies, Inc (MST), has purchased 5 Wifiber wireless fiber links from GigaBeam
Plans deployment of future products capable of 10 Gigabits-per-second
Wifiber G-2.7 series of wireless fiber links is designed to operate at 2.7 Gigabits-per-second, the highest speed currently available for commercial licensed spectrum wireless links.
