WiMAX

ABSTRACT
Imagine a single wireless technology that can:
• make portable Internet a reality by extending public WLAN hotspots to
metropolitan area coverage for mobile data-centric service delivery,
• connect enterprises and residential users in urban and suburban
environments where access to copper plant is difficult,
• bridge the digital divide by delivering broadband in low-density areas.
Thanks to its innovative technology, WiMAX will offer broadband wireless
access at data rates of multiple Mbit/s to the end-user and within a range of
several kilometers. The same radio technology will also offer high-speed
data services to all nomadic terminals (laptops, PDAs, etc.) with an
optimized trade off between throughput and coverage. Ultimately it will
enable the "Portable Internet" usage replicating on the move the same user
experience as at home or at the office.
Given its huge benefits, WiMAX will develop as a powerful radio access
solution with many integration synergies in mobile or fixed network
architecture. WiMAX will also enable end-users to benefit from an "Always
Best Connected" experience when accessing their applications via the best
available network, at home, on the pause, or on the move. WiMAX
particularly fits in Alcatel's vision for a User-Centric Broadband World in
full complementarity with the other broadband access technologies: from
ADSL to UMTS and their evolutions towards higher speed and data
efficiency
