What can WiMAX technology offer

WiMAX technology puts up wireless data in a concerned form as equate to WiFi but its level and speed provide to build hybrid and wireless networks, of any size, anywhere. It is made to advance conformance and interoperability of Wireless Metropolitan Area Network. WiMAX proffers a ordered technology according to its standard. WiMAX technology open could let product manufacturers make revenues of scale via producing number of WiMAX products & ingredients to single IEEE 802.16 standard, this also allow ingredient makers buy cut-rate, standards conformable components from rival component providers. This would definitely help instant wireless service providers.

WiMAX technology will offer up high data speed network connections and in this mode assist as a backhaul for WiFi LAN (WLAN) hot points, where people on the affect can approach carriers’ WiFi services on mobile technology basis, because this technology allows interoperability among different systems. And service suppliers lacking a mobile network can utilize a WiMAX technology network at comparatively low price. WiMAX technology perhaps will put up a much cheaper, lighter to build up network infrastructure other than the physical medium of WiFi backhauls that cable, T1 or DSL systems shortly offer.

Because WiMAX is situated on IEEE 802.16 Standard and HiperMAN, the IEEE and ETSI have each become accustomed it’s standard to take in many of the other’s grand features. IEEE 802.16 standard partitioned its MAC (Medium Access Control) layer into sub-layers that hold some some other transport equipments and technologies, together with Ethernet, IPv4, IPv6 and other asynchronous transfer mode. This allows for traders to use WiMAX technology and no matter what technology they hold for transmission. WiMAX technology has a wide communicating range up to 50 kilometers because principles provides WiMAX network to transfer data at high rates and because of this move towards use of directing antennas that gets persistent radio signals. WiMAX base station provide service to only 500 users at a time not more than that merely because to they are sharing bandwidthand this factor may cause lower date rates among. Technically every single station will perhaps allow for communication an area inside a 10 miles radius. To equate WiFi with WiMAX technology the last has a range of few thousand feet. while WiFi has a range of just a few hundred feet.

Moreover WiMAX network broadcasts data communication over different broad signal frequency ranges. And this exceptional capacity to work in different ranges allows for to communicate above the frequencies that will evade interference with some other wireless network applications. Also the flexibility of this system’s communication allows providers to employ different frequencies that depend on the speed and range taken for a special data communication. Expanding data content and bandwidth via dividing broad capacity channels to many narrowband channels, the WiMAX technology accomplishes higher data transmission rates in part by OFDM (Orthogonal Oftenness Division Multiplexing).Each channel uses different frequencies that can transmit some other pieces of a message at the same time.

One of the important vantages of data transmitting is that the channels do not overlap, in spite of the fact that the spaces between channels are exceedingly close. The primary IEEE 802.16 standard uses the 10 to 66 GHz frequency range And it is very fit because this frequency range shrinks the multi path distortion that arises when transmitting signals that do not follow the line of sight echoed items and finish off out of sink, thus jumbling the inbound communication and reducing bandwidth.

In theory WiMAX network can offer single channel data rates up to 75 Mbits/s equally on the downlink and uplink. Service suppliers can use individual 802.16 channels for single broadcast to offer up bandwidths of up to 350 Mb per second.

Third generation mobile network technologies will put up around 115 Kbps. The accepted IEEE 802.11b WiFi WLAN technology data rate are special to 11Mbps, on the other hand earlier 802.11a and 802.11g put up up to 54Mbps in handy conditions but practically all of the them transmit at lesser speed.

In the meantime WiMAX network is extremely scalable as it is easy to take broadcast channels to offer special bandwidth as required. And as far as security system is concerned in WiMAX technology it uses PKI (Public Key Infrastructure) authentication, which transmit via digital certificates by keying out parties over trusted authorities. The IEEE 802.16 system encrypts data by using 56 bit DES (Data Encryption Standard) keys.

The wireless services are supplied at high frequences as the line of view restraints necessary the setting up of many another antennas to cover up the equivalent area and this gains to a great extent the expenditure of setting up wireless technology. The available frequencies for new wireless standards such as IEEE 802.16 are higher as some of the other wireless technologies are more sought-after to decrease ranges that have been authorized for other use.

The WiMAX technology is forever supported by the WiMAX Forum which comprises a group of commercial-grade leaders such as AT&T, Cisco, Samsung, Intel, and some other giants. This forum takes many working groups that highly focused on regulatory, marketing, technological characteristics. Furthermore the certification working group stands for to certify interoperability among WiMAX products from manufacturers internationally.
