Conventional in-building network: The inefficient network of the past
The conventional in-building cellular networks are the remains of the past. On this system, each and every Cellular Service Providers are working independently in approaching target buildings, and installing their own network infrastructure.
Because of that approach, this type of network is also known as "Single Provider in-building system". Simply said, one network serves one service provider. Two networks for two providers, and so on.
This type of network is highly inefficient. Imagine a building with four or more service providers providing their service there. There would be a lot more number of unnecessary backbones (the big cables on the cable shaft), as each provider will install their own set. And there would be a LOT of antennas. If one provider needs 100 antennas, there would be 400 antennas installed. The vast number of antennas will make the building's ceiling look cluttered and ugly. Furthermore, there would be massive amount of cables, usually totalling several kilometers long to cover the whole building and the number of kilometers multiplies according to the number of providers providing service in the building.
The below is typical installation of Conventional, or Single-Provider in-building system :
