NEXT GENERATION WIRELESS TECHNOLOGY
[attachment=40079]
ABSTRACT:
Gi-Fi will helps to push wireless communications to faster drive. For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt, introduction of Wi-Fi wireless networks has proved a revolutionary solution to “last mile” problem.However, the standard's original limitations for data exchange rate and range, number of channels, high cost of the infrastructure have not yet made it possible for Wi-Fi to become a total threat to cellular networks on the one hand, and hard-wire networks, on the other. But the mans continuous quest for even better technology despite the substantial advantages of present technologies led to the introduction of new, more up-to-date standards for data exchange rate i.e., Gi-Fi.
INTRODUCTION:
,Wi-Fi (ieee-802.11b) and WiMax (ieee-802.16e) have captured our attention.As there is no recent developments which transfer data at faster rate..as video information transfer taking lot of time.
This leads to introduction of Gi-Fi technology.it offers some advantages over Wi-Fi, a similar wireless technology.In that it offers faster information rate(Gbps),less power consumption and low cost for short range transmissions.
Gi-Fi which is developed on a integrated wireless trnsceiver chip.In which a small anteena used and both transmitter- receiver integrated on a single chip.which is fabricated using the complementary metal oxide semiconductor (CMOS)process. Because of Gi-Fi transfer of large videos,files will be with in seconds.
WHY Gi-Fi ?
The reason for pushing into Gi-Fi technology is because of slow rate,high power consumption,low range of frequency operations of earlier technologies i.e.,Bluetooth and Wi-Fi. see the comparisons and features of those two technologies.
FUNDAMENTAL TECHNOLOGIES IN 802.15.3C:
It is fundamental technology in digitital TV. It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference. It is also supported in the WPAN standard.TG3c is developing a millimeter-wave-based alternative physical layer (PHY) for the existing 802.15.3C. The millimeter-wave WPAN will allow high coexistence (close physical spacing) with all other microwave systems in the 802.15 family of WPANs.
4. Cost-effective:
Gi-Fi is based on an open, international standard. Mass adoption of the standard, and the use of low-cost, mass-produced chipsets, will drive costs down dramatically, and the resultant integrated wireless transreceiver chip which transfers data at high speed,low power at low price $10 only.
