Learn About LMDS

Users value LMDS spectrum for a number of reasons. First, LMDS wireless links support carrier grade broadband alternative access services. Second, LMDS providers generally hold a deep supply (averaging over 1GHz/market) of high capacity LMDS spectrum providing organizations with the peace of mind of adequate spectrum supply for future bandwidth needs. Third, using licensed spectrum operators can deliver carrier grade solutions without signal interference and related issues as they would when employing unlicensed spectrum. Fourth, the radio/antenna designs in the LMDS band enable users to deliver innovative and cost effective solutions, including:

  • Municipal Networks – transmission equipment small enough to position on a street light, for example, to act as a backhaul point for WiFi and WiMax deployments.
  • Security Applications – co-locate this equipment on an outdoor surveillance post, for example, to transmit real time, bandwidth intensive high definition video feeds to remote monitoring centers.
LMDS vs. Common Carrier spectrum
LMDS spectrum can be more cost effective to deploy and manage than equivalent common carrier spectrum licensed on a link by link basis. Some important facts to take into consideration when comparing the various wireless options include:
  • LMDS radios typically use smaller antennas (1 foot diameter or less in some cases) when compared to common carrier antennas. Common carrier spectrum typically requires the deployment of radio equipment with much larger antennas (from 2 ft. up to 6 ft. in the case of 6 GHz common carrier). The deployment of larger antennas will generally result in higher roof right lease costs.
  • FCC licensing fees for common carrier spectrum can arbitrarily increase year over year, so long term business case analyses have an unknown cost variable to address.
  • Operators can request to move the location of a deployed LMDSXchange licensed link for a small processing fee (typically less than a few hundred dollars) whereas moving common carrier links requires the full FCC common carrier license fees and related spectrum coordination costs each time a new site is required.
These are just some of the benefits a network optimized using LMDS spectrum can bring to Radio Frequency network planners.
