Not really, the service , IMO, depends on the number of people using the same tower..the quality of connection entirely depends on the tower, unless there was some hardware problem with the CPE, but that's usually either rare and/or easily fixable by rotating etc.
In my area, the tower is used by more than 400 people. According to the engineer who installed the connection in my area, it's the only tower covering many colonies together. So it's obvious that they'll have to keep their service up otherwise they risk losing the loyalty of 400+ customers.
