Microwave Backhaul
SpectraNet has designed point-to-point microwave backhaul networks for the major US cellular carriers and enterprise service providers for over 15 years. Judicious choice of network topology, radios, frequencies, and antenna sizes finds the balance that exceeds service-level agreement requirements while minimizing network cost — with frequency coordination and licensing handled end to end.

Representative work
Designed, coordinated, licensed — and measured.
Port-security video links
Gigabit Ethernet 70–80 GHz millimeter-wave links for high-speed video, alongside 23 GHz links at 300 Mbps, for a Homeland Security project. All designs, frequency coordination, and licensing by SpectraNet.
Spatial diversity on a 50-mile path
Microwave link design for a 50-mile over-the-water path, using spatial diversity to hold availability through severe multipath conditions.
Line-of-sight validation
Links and Fresnel zones exported from the microwave design package into Google Earth to validate line-of-sight before anything is built.
Terrain & clutter path profiles
Path profiles built from 1/3-second terrain elevation data combined with high-resolution LIDAR clutter.
Multipath fading — theory vs. measurement
Fade-depth predictions versus K-factor, checked against measured receive power during over-water VHF fade events. Peak measured fades landed in the theoretically predicted range.
Network reliability engineering
Vigant-Barnett fade statistics, average fade duration versus margin, and automated multi-hop reliability summaries for hub-and-spoke designs.
MMW / FSO hybrid links
Maximum distance versus availability modeling for hybrid millimeter-wave / free-space-optics links, including FSO up-time share when the MMW radio is primary.
FSO deployments worldwide
Free-space-optics installations in Puerto Rico, Singapore, and Rio de Janeiro — and the disaster-recovery link connecting Merrill Lynch's NJ and NY offices after 9/11.
Radome ice attenuation
Attenuation versus antenna-radome ice thickness, calculated from the measured complex permittivity of ice across microwave frequencies.
