High speed data transmission formats for radio LANs

Mobile radio research has tended to concentrate on the difficulties associated with wireless voice transmission. These signals typically require low bandwidths and are able to tolerate error rates in the region of 1 to 1000 bits. However, over the last few years, the decreasing size and increasing power of portable computers has resulted in a growing demand for a new type of wireless indoor system. This paper attempts to predict the maximum data rates for a typical network operating in an indoor frequency selective environment. To lower the error rates for high speed data transmission the impact of techniques such as diversity combining, frequency hopping and pulse shaping is also investigated.<
