We propose a new type of wireless system, which is to provide for multimedia, bandwidth upon demand and quality of service (QoS) to the user. The system proposes to disable the problem caused by the unavailability of wired access by providing large bandwidths upon demand to individual users. The scheme proposes the use of optical beams in interconnecting mobile-telephone-switching-offices (MTSO) with each other using distinct WDM measures in a multihop scenario. Small microcells capable of growing themselves and reducing back to their macro size are employed. Traffic is dealt with by the anomalous expansion and contraction of these cells. A high data rate to individual users is provided by a FH-CDMA based system whereby the chip rate becomes proportional to the channel quality. This ad-hoc method of adaptive coding helps the user maintain a uniform data rate throughout time. The benefits of this approach are dealt with in great detail and issues of reliability and hand-off as well as system diversity are dealt with. As a further approach the authors suggest the interaction of this system with an ail-optical underlaying network.
