Those which survived the slower than expected roll-out of outdoor small cells are now looking at a belated, but real, windfall as operators pursue densification programs, putting real pressure on authorities to ease siting and other obstacles to deployment. And of course, many of the early pre-5G trials are focusing on high frequency bands, and so of necessity on small cells. One of the start-ups which devised wireless backhaul solutions for small base stations deployed close to the floor and the radio ‘clutter’ was Tarana Wireless, which has now gained a partnership with Nokia, a trial…
