Think of E-Band as the city-loving younger member of the 5G backhaul family
Downtown, where all the lights are bright. In this blog I am singing the praises of E-Band, which sits in the 70-80 GHz range. It’s the newest member of the microwave transport tribe and it’s being rapidly taken up by operators to meet their 5G backhaul needs, especially in urban and suburban areas.
Sales of E-Band products are booming, with a Compound Annual Growth Rate (CAGR) of 39% being predicted to 2024*. Happily for me, Nokia has been leading the charge with Dell’Oro Group’s recent Microwave Transmission report identifying Nokia as the only vendor of the large manufacturers to grow its Q1 2020 microwave revenue year-over-year and gaining market share.
Why is E-Band seen as an important solution for 5G? It is clear that the traditional microwave bands alone won’t be able to provide the multiple Gigabit per second capacity that 5G requires. Instead, E-Band, used alone or with other bands, will be the pillar of 5G backhaul.
E-Band for urban
E-Band is very well suited to urban and suburban areas where high capacity is needed over relatively short backhaul distances. E-Band alone can provide very high peak capacity over distances up to around 3 km, while aggregating E-Band with microwave reaches further, out to about 10 km, yet still providing the capacity that 5G demands. Beyond 10 km, microwave with microwave carrier aggregation can meet the needs of rural areas not needing the highest levels of capacity.
E-Band products offer superb support for operators deploying 5G in urban areas. With E-Band, operators can connect small cells and macro cells with fiber-like speed in areas where fiber is impractical or slow and costly to deploy. In addition, Nokia offers the most compact solution on the market, with integrated antennas that blend with urban environments and simplified installation.
Most sites in urban areas require backhaul of less than 1 km, making them great for E-Band with integrated antennas that are 80% smaller than conventional products. There will also be a need to backhaul sites more than 2 km away, and for these situations Nokia has its high power Wavence product coupled with a high gain antenna for +20 dBm output power. With Cross-Polarization Interference Cancelling (XPIC) technology, the receiver threshold can be further increased by up to 4 dB.
E-Band has a bright future in the 5G world. This is driving rapid development of products and Nokia offers a wide range of options in its Wavence portfolio to meet every operator backhaul need.
