Abstract :
With the transition to digital, the MMDS (multichannel microwave distribution system) operator will be able to economically devote portions of the currently restricted bandwidth resource to interactive services. The Internet is seen as a market driver for interactive services. A number of differing designs exist for the provision of Internet via MMDS. At its simplest level, Internet via MMDS involves converting an existing video channel to data using an off-the-shelf cable modem and providing the subscriber with a receiver and modem. The issue centres on the provision of adequate quality of service which is a function of the data-rate perceived by the user. The traffic models described indicate that provisioning Internet to a growing market will require more efficient use of spectrum, necessitating the reuse of frequencies
