Wi-Fi and Specialty Wireless

We survey, design, build and integrate Wi-Fi networks (802.11n, ac etc). These services are provided either separately or as integrated solutions to create a flexible, cost effective package.

We work extensively with Cisco, Ruckus and Meraki equipment, and our experience spans all commonly used product lines. Our customers include hospitals, industrial sites, retailers, malls, medical and legal offices, airports, ports, warehouses, military bases and financial institutions. We utilize Ekahau and Airmagnet professional survey tools.

Our wireless services include point-to-point telemetry, special-to-type radio communications solutions, and complex networks. These have substantial experience in Smart Grid, and large scale transportation networks.
