1. Introduction

The SST-900 and SST-2400 are radio modems that can be
used in multiple access networking. The transmission method in­cludes peer-to-peer, multi-point structure for wireless data
communication. Based on direct sequence spread spectrum and
RF technology operating in ISM bands, 902-928Mhz for SST-900
and 2400-2483.5MHz for SST-2400.
