The bandwidth limitations of spread spectrum RF technology are easily removed by use of optical carriers. A variety of wireless connectivity system applications have been achieved using IR LED (not laser) at data rates up to 125 Mbps and with low frequency corners below 100 Kbps. By use of the UWIN^TM principle it is possible to achieve wireless communications which are protocol independent. Thus, an urgent installation which must serve today as an Ethernet or Token Ring wireless connection in the future can be used at FDDI, Fast Ethernet, 100 VG Anylan or ATM without any modification to the original installation. In this paper we describe three separate applications of this principle where there are significant trade-offs between range and angular coverage.
