Millimeter wave systems can meet growing indoor bandwidth requirements

The Wireless marketplace has many segments or verticals, but the two largest categories are indoor and outdoor. Indoor wireless consists of various access technologies – typically Wi-Fi and cellular small cell. In the outdoor segment there are more uses cases and hence more vertical alignments. The most common of these is cellular, which can then be broken down into macro, micro and pico, or small, cells. A smaller but also important outdoor access technology is the Fixed Wireless Access market.

Along with these access use cases, wireless has long been used to connect cell towers and buildings with point-to-point technology, all deployed in the microwave and millimeter wave bands from 6GHz to 86GHz. These systems can support connection capacities as high as 10Gbps full duplex. What has never been seen on the market until recently is the concept of using microwave or millimeter wave frequencies to perform the same function – indoors. Despite the clear attractions of using wireless in this role – cheaper, faster and more flexible to use when compared to fiber or cable, there were significant obstacles to this approach indoors, primarily the requirement that systems in these bands must have a clear Line of Site to operate. Clearly in an indoor environment with hallways, walls and unique floor plans on an almost per building basis this ends up being a barrier too high to overcome if LoS is a requirement.
