 GHz frequency bands and optimized for micro cell backhaul. The product can operate at 5, 3.5 and 2.3-2.7 GHz bands in TDD mode. The low band enables non-LOS operation. The product can use licensed or unlicensed spectrum. The unlicensed spectrum facilitates fast and easy deployment and savings on the license fee. Dragon Wave Harmony Radio Lite is outdoor capable, has an integrated antenna and has a standard Ethernet interface. It provides synchronous Ethernet and IEEE 1588v2 support for the base station frequency and time synchronization. 6.10 Summary This chapter introduced small cell product categories including all-in-one micro and pico cells for outdoor and indoor public premises as well as offices, low-power RF heads with high-capacity front haul for outdoor and indoor use and femtocells for homes and small office premises. New small cell solutions will take market share from traditional passive and active DASs. Wi-Fi small cells provide a means of offloading traffic from mobile networks in homes, offices and public premises. Small cell base station products offer high capacity with an output power ranging from tens of milliwatts to a few watts in very compact packages of a few litres in volume and a few kilograms in weight. Wireless backhaul products with near-LOS or non-LOS capability were also presented offering capacity of more than 200 Mbps in sub-6 GHz bands. 3GPP specifications support different base station categories by offering separate RF requirements for the low-power small base stations.
