More compacted construction in cities combined with better isolation of concrete walls reduce penetration of radio signals. Especially in larger buildings, this development leads to a situation of little or almost no radio reception.
Establishing an in-house supply increases radio coverage to even levels within buildings. This solution distributes radio signals through repeaters within the whole building complex. ErvoCom realized such an in-house supply solution for MainTower. The solution is based on GSM and LTE technology.
