SpectraNet has been doing microwave backhaul design for the major US cellular carriers and enterprise service providers for over 15 years. Using judicious choice of network topology, radios, frequencies, and antenna sizes, we find the right balance to exceed service level agreement requirements while minimizing network costs. Microwave backhaul links can be imported into Google Earth to show line-of-sight potential which includes a visual look at Fresnel zone obstructions–this greatly decreases time spent in the field doing site and path surveys. We use 3D building data for urban deployments, and a combination of 1/3 second terrain elevation data with clutter for suburban and rural point-to-point designs. Clutter can be high resolution/high accuracy LIDAR data to accurately depict tree and building heights. SpectraNet has extensive databases of tower and building information for the US, and a large database of radio, antenna, and waveguide/coax specifications. We provide detailed site survey and path survey forms based on link designs, and also provide target receive signal levels (RSL’s) for installers.
