Wifiber

Prepared By:- Bhatt Drashti H.(6th C.E.)

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.

Application…..

WiFiber links with an existing fiber links provides fiber optic backbone diversity and disaster recovery.

WiFiber links provide campus connectivity and fiber optic backbone access. Due to this, it is flexible, fast and safe

Contd…..By alternative access to remote data storage we can ensure that the data transmission is secure, protocol independent, and means have very low time delay.

WiFiber links enable increased date and voice traffic for hard to reach antennas. This increases the data transmission speed, data rate, clarity etc.

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 BusinessesWireless 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.

Current users……. Future Scope……!!!!!!!!!!!
