We had a great discussion at the Fog Computing conference about the use of millimeter technology, and agreed that 60 MHz in particular is catching people’s attention. Mark Kelley of OpenRan and Gabriel Desjardins of Broadcom led the discussion, pointing out the issues we are facing in deploying the necessary backhaul to support all of the data requirements. While some customers expect to be serviced by cellular operators, the same technology for backhaul beam-forming can be used by municipalities and multi-location companies to support their requirements. Millimeter technology is lightly regulated by the government because candidly, the chance for interference is limited. What is problematic is keeping the beam on track as heat, wind and other environmental issues distort the location of the signal.
The use of Aoptix Intellimax is an interesting solution since it used both optic laser line of sight and millimeter microwave to transmit at 2GB over 10 Km. The use of both optics and millimeter beam-forming means that adjustments to weather can be properly accounted for on the system. Beam Forming needs to be dynamic since the tower can have a two percent deviation, but fortunately, combing the optics with the wireless gives the system the opportunity to point and adjust. Once the adjustment is done the system tracks the impact of the deviation and adjusts appropriately.
As the use of small cells outside the office continues to grow the use of backhaul will increase, and as per OpenRan’s Mark Kelley will start to require backhaul mesh networks. This fits in nicely to the ideas associated with Network Functions Virtualization [NFV]..Read More .
