Title of the Talk Small-cell Challenges for Mobile Networks' Wireless Backhaul
Higher data rates in mobile networks imply smaller distances from base-station to mobile user. Number of network elements increase while the cost pressure is high. For economical purposes wireless connections are preferred in mobile backhaul infrastructure in several cases and millimetre-wave bands are the only option to carry the needed multi-gigabit capacity. New kind of network topologies are needed. The author will present this challenge from mobile networks' wireless backhaul point of view, bring out possible solutions and the consequences for wireless technology.
