Abstract

A techno-economic analysis of the 5G eMBB (enhanced Mobile BroadBand) scenario in dense urban areas has been accomplished by radio capacity modelling of probable 5G technologies within a 1km2 grid representing central London. Different density networks were modelled at: 700MHz (macro network), 3.5GHz (micro network) and 24-27.5 GHz(hot spots) – together with 802.11ac access points. Using published data on network costs various deployment options have been evaluated for capacity, headline rate and CAPEX/OPEX.

It has been shown that reaching headline rates of 64-100Mbps everywhere is possible with a number of different technology options. Massive increases in capacity (in excess of 100Gbps/km2 ), however, can only be realistically achieved with millimetre wave (outdoor) and WLAN (internally). The cost of deploying such capacity, however, will be several times that of LTE – we estimate a 4 to 5 times increase in costs for a 100Mbps everywhere network that has x100 capacity increase over existing LTE networks.

The cost of rolling out 5G is becoming an important issue and this work provides one of the few published estimates of the economics of ultra-high capacity networks.
