Moreover WiMAX network proclaims data communication over several broad signal frequency ranges. And this exceptional potential to work in several ranges allows to communicate above the frequencies with a purpose to steer clear of interference with other wireless network applications. Also the versatility of the program's communication allows providers to hire the several frequencies that remember on the rate and diversity needed for a distinctive data communication. Amplifying data potential and bandwidth by means of dividing broad potential channels to many narrowband channels, the WiMAX technology attains greater data transmission rates in part by OFDM (Orthogonal Frequency Division Multiplexing).Every channel uses the several frequencies that can transmit the several pieces of a message at an identical time.

In principle WiMAX network can offer single channel data rates up to 75 Mbits/s equally on the downlink and uplink. Service providers can use several 802.sixteen channels for single broadcast to offer bandwidths of up to 350 Mb per second.

WiMAX technology offers wireless data in a associated diversity as compare to WiFi then again its level and speed let to build hybrid and wireless networks, of any size, anywhere. It is formed to encourage conformance and interoperability of Wireless Metropolitan Area Network. WiMAX offers a fixed technology according to its general. WiMAX technology open could let product manufacturers make revenues of scale by means of producing number of WiMAX products & parts to single IEEE 802.sixteen general, this also let portion manufacturers buy low in charge, standards compliant parts from rival portion providers. This would real help existing wireless service providers.

Because WiMAX is stylish on IEEE 802.sixteen Standard and HiperMAN, the IEEE and ETSI have each changed into accustomed it's general to absorb many of the other's crucial tendencies. IEEE 802.sixteen general partitioned its MAC (Medium Access Control) layer into sub-layers that hold some the several transport equipments and technologies, along with Ethernet, IPv4, IPv6 and other asynchronous transfer mode. This allows traders to use WiMAX technology and whatsoever what technology they support for transmission. WiMAX technology has a wide communication diversity up to 50 kilometers because principles allows WiMAX network to transfer data at greater rates and brought on by this circulate in opposition to use of directional antennas that generates  power radio signals. WiMAX base station provide service to only 500 users at a time not more than that just because to they could be sharing bandwidthand this element also can cause lower date rates among. Technically every single station will possibly provide communication an area inside a 10 miles radius. To compare WiFi with WiMAX technology the ultimate has a diversity of few thousand feet. at the same time WiFi has a diversity of only a few hundred feet.

WiMAX technology will offer high data speed network connections and in this manner serve as a backhaul for WiFi LAN (WLAN) sizzling spots, whereby people on the circulate can access carriers' WiFi services on cellular technology foundation, because this technology allows interoperability among the several systems. And service providers lacking a cellular network can use a WiMAX technology network at comparatively low price. WiMAX technology possibly will offer a much cheaper, easier to build network infrastructure other than the physical medium of WiFi backhauls that cable, T1 or DSL systems presently offer.

In the meantime WiMAX network is particularly scalable because it is simple to come with broadcast channels to offer extra bandwidth as required. And as far as security is in contact in WiMAX technology it uses PKI (Public Key Infrastructure) authentication, which transmit by means of digital certificates by choosing parties over trusted authorities. The IEEE 802.sixteen system encrypts data through the use of 56 bit DES (Data Encryption Standard) keys.

One of the genuine advantages of data transmission is that the channels do not overlap, in spite of the truth that the spaces between channels are particularly close. The simple IEEE 802.sixteen general uses the 10 to 66 GHz frequency diversity And it is very relevant because this frequency diversity shrinks the multi path distortion that arises when transmitting signals that do not observe the line of sight echoed items and finish off out of sink, consequently jumbling the inbound communication and reducing bandwidth.

Third generation cellular network technologies will support around 115 Kbps. The accepted IEEE 802.11b WiFi WLAN technology data rate are limited to 11Mbps, on the other hand newer 802.11a and 802.11g provide up to 54Mbps in favorable circumstances then again practically all of the them transmit at lesser speed.

The WiMAX technology is always supported by the WiMAX Forum which comprises a group of industrial leaders such as AT&T, Cisco, Samsung, Intel, and some other giants. This forum involves many working companies that incredibly focused on regulatory, marketing, technological tendencies. Moreover the certification working group intends to certify interoperability among WiMAX products from manufacturers internationally.

The wireless services are supplied at greater frequencies as the line of sight constraints required the putting up of many antennas to canopy up the equivalent area and this increases to an awfully good extent the expenditure of putting up wireless technology. The available frequencies for new wireless standards such as IEEE 802.sixteen are greater as some of the other wireless technologies are more sought-after to decrease ranges that have been approved for other use.
