Simple- it inhabits the same band almost everything else inhabits- 2.4GHz. To an extent, the reason Bluetooth is unreliable is the same reason most Wifi is unreliable in crowded areas. There's a lot of appliances that use that bandwidth over incompatible standards.
Even worse are the "spark" kind of 2.4GHz appliances that don't play nice, like wireless camera systems and baby monitors. If your strong-signal wifi or bluetooth keeps dropping, it's far more likely to be one of those at fault than anything else.
