Wireless LAN design alternatives

We have discussed several alternatives in wireless LAN design: media choice, operating frequency, operating mode, network topology, and access method. Although each technical choice presents both advantage and disadvantages, we argue that there is a design point that provides the best fit with present and future wireless LAN user needs. Considering all factors - including robustness, regulatory considerations, and interference avoidance - using a product based on the slow frequency-hopping spread-spectrum, in the 2.4 GHz ISM band, relying on a base station remote station network topology and using a TDMA-based access method (Fig.4) is the best way to meet the needs of radio-frequency wireless LAN users.
