STRIKE: spectrally efficient fixed wireless network based on dual standards

One of the major challenges of the telecommunication community for the coming years will be to make multimedia services available to everyone, even to those who are in remote places. Broadband fixed wireless access (BFWA) is one of the best positioned radio access technologies to provide broadband access with performances that surpass current 3G mobile data rates and are similar to wired xDSL systems. The paper addresses the solutions which are proposed and demonstrated in the frame of the IST-STRIKE project to enhance spectral efficiency for BFWA and to guarantee end-to-end quality of service (QoS) through a dual mode HiperMAN/HiperLAN system. The first aspect is covered by the use of multi-transmit multi-receive (MTMR) techniques. Indeed, as it is foreseen that the data rates available with the studied standards will be sufficient for the majority of single user needs, the best way to increase the capacity and lower the deployment cost is to multiply the number of simultaneous transmissions. Besides, it is shown that to ensure QoS for high data rate and time constrained services (such as video streaming), interworking is provided at the data link control (DLC) level.
