IEEE 802.16e (Mobile-WiMAX) for rural deployment

Abstract

The IEEE 802.16e (or simply 16e) is an emerging global standard targeted for broadband services to mobile/nomadic users within urban areas with macro cellular type deployment. Other applications of 16e can be micro cell indoors and outdoors serving hotspots and enterprises. The 16e promises wideband operation with high spectral efficiency. Net throughputs up to net 70 mbps peak and 20 mbps average are possible in 10 MHz channels. The 16e standard for urban mobile applications is expected to be ratified in Sep. 2005. The WIMAX forum has approved two profiles wave 1 and 2. The former is entering Korean deployment in mid 2006. Wave 2 profiles address more advanced features will begin trials in late 2006. Clearly, 16e is a very flexible standard capable of multiple applications. In this paper the author argues that the flexibility in 16e also makes it suitable for efficiently supporting rural applications also. Requirements for rural deployment and a possible rural profile for 16e are discussed. Also it is shown that it can be configured to offer attractive performance and cost advantages.
