BridgeWave Communications, a supplier of gigabit wireless solutions, describes how their unlicensed 60 GHz radios are used to provide several hospitals with gigabit connectivity.
Franciscan Health System, based in Tacoma, Wash., has five hospitals linking to its main business offices called the Service Center. When their two licensed 100 Mb/s microwave radios began to fail, the Service Center was often left with one link and unreliable network connectivity.
Moonblink Communications, a value-added distributor, recommended a gigabit wireless solution using BridgeWave’s 60 GHz, AR60. In addition, the ultra narrow beamwidth of these links provide an added level of security and interference immunity that other wireless solutions do not offer.
In a matter of days, BridgeWave’s 60 GHz AR60 was purchased and installed, restoring network connectivity. Franciscan Health System decided to install additional BridgeWave 60 GHz links creating a gigabit ring between facilities to ensure a highly-available, secure network, bypassing the costs associated with leasing Metro Ethernet services.
Bridgewave’s AdaptPath solution pairs a primary path BridgeWave 60GHz or 80GHz GigE radio with a lower speed, highly rain-tolerant secondary path. The resulting dual technology solution allows gigabit links to be deployed over longer distances, while maintaining up to 99.999% service availability.
BridgeWave’s AdaptRate mode switching, switches single path transmissions from GigE to 100 Mb/s data rates, using a temporary increase in link budget. AdaptRate reduces the over-the-air signal bandwidth rather than changing modulation, delivering increased signal to noise when required (such as in a violent rain storm).
