2、an impressive rate.By the end of 2021 more than 210 communications service providers had launched commercial 5G services,and the 5G share of mobile network traffic is expected to be 60 percent by 2027.Backhaul networks will need to be able to cater for high bandwidths to support 5G,but also to be fl

3、exible to serve the large variations in different markets and deployment types.Over the last 5 years,E-band has increased by an impressive 500 percent,to 6 percent of the total installed microwave base,proving to be a key player for 5G backhaul.E-band is now also available in India,and the usage of

4、E-band will continue to grow globally in coming years,reaching 25 percent of new deployments in 2027,with both standalone and multi-band solutions.In 2023,the upper 6 GHz band is up for consideration as a future 5G NR band.Since 6 GHz is a vital fixed service band for rural application,it is imperat

5、ive to coordinate those links on a national level with 5G in countries where this band is used for fixed service.The use of carrier aggregation in long haul systems makes it possible to increase capacity by around 50 percent Executive summaryThe continued strong growth of 5G puts a focus on power ef

6、ficiency and maximizing capacity in spectrum-limited networks.with the same number of radios.This is especially useful when only narrow channels are available,achieving increased capacity with the same availability,while reducing hardware footprint,power usage and total cost of ownership compared to
