The WTM 4500 from Aviat Networks is an Ultra-Efficient, High Capacity outdoor microwave link that operates from 6 to 11 GHz. This radio link has an integrated space diversity receiver and provides a data rate up to 1.2 GBPS, with 4096 QAM Modulation and 112 MHz channel.
This rugged microwave link has been developed for applications that require ultra-reliable links over long and difficult paths, such as over flat desert terrains or over large bodies of water, where highly reflective conditions can play havoc with a microwave link, potentially causing extended outages. The usual method to counter these adverse conditions is to deploy links with space diversity, where a second receiving antenna enables the automatic selection of the best and error-free received signal. This normally requires the deployment of a complete second radio at each end of the link, increasing costs, tower loading and installation complexity.
