Colt Technology Services in partnership with NEC, announced that it is conducting the first ever live trials of small cells using Femto-as-a-Service (FaaS) with a leading, large-scale European mobile operator, using a multi-operator small cell (Femto) gateway. The FaaS offer from Colt breaks down the investment barrier for mobile operators to start their own Small Cell service as it eliminates the need for mobile operators to have a dedicated Femto Gateway in the operator core.
