WiMax Chip: Replacing the Role of Modem in Broadband Connections

Nextel is one of the communication giants in the United States to adopt WiMax technologies.  The Nextel WiMax deployment was designed to provide subscribers faster wireless connectivity in order to maximize the broad range of communication applications available in the market. 

Through Nextel WiMax deployments, subscribers will not only get crisp communication signals but will enable them to use their different gadgets to use modern web technologies and applications.  Mobile Internet connections would be more convenient and productive because WiMax solutions can provide faster data transfer rates.  Users will also be able to get connection speeds that are twenty times faster than 3G networks.  The technology will enable companies to adopt virtual office environments for their employees because of enhanced connections.

Before adopting WiMax technology for its network, Nextel ensured that it could meet its critical requirements for mobile telephony.  First, Nextel required providers to give them a wireless connectivity solution that will be economical and over-head cost efficient.  Second, the provider must meet the speed and reliable connectivity requirements of Nextel.  And the provider should enable Nextel solutions to interoperate with different suppliers and networks.  The capability of WiMax technology met all these requirements thus leading to its adoption.  WiMax also provided Nextel a first in the market solution for its communication services and devices. 

Nextel’s frequency allocation band of 2.5 GHz is also compatible with WiMax technology.  By deploying WiMax, Nextel has been able to provide subscribers with connectivity speeds reaching 4 megabytes per second on a highly portable network.

A WiMax chip serves as the communication exchange device acting the role of a modem for wireless WiMax connection.  Most designs of WiMax compliant chips have a MAC microprocessor or the media access point and Radio Frequency components.  It should be installed on the WiMax base transmitter and on the customer premises device.  Communication takes place between the two WiMax chips and performs dual functionalities both as sender and receiver of data transfer.

The first roll out of WiMax chips coincided with the formal standardization of WiMax wireless technology.  Chip makers raced to meet standards and offer WiMax chips both for end user devices and for the base stations of WiMax carriers and service providers.  As WiMax technologies developed and standards for mobile wireless connectivity have been established, the WiMax chip also evolved.   Today, computer makers are integrating WiMax chips into laptops to make them WiMax enabled.  There are also WiMax chips on PCMCIA cards that users can insert into their system.  This enhances the mobility of devices because they will not be dependent anymore on external antennas.

The development of mobile WiMax chip reduced the cost of the wireless broadband system.  For one, the integration of the chip on the actual user device will eliminate the need for an outdoor communication device.  There will be no need for an extra installation as the chip is fully integrated into the computer system.  This also paves the way for the development of WiMax chip that can be integrated into more mobile communication devices such as PDAs and smart phones.  These devices can access WiMax services and get broadband connection using the micro WiMax chip.
