WiMAX TECHNOLOGY

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
