Broadcasting network is a hodgepodge.
Its TV network is its own exclusive wired network. The lines of the Internet are very complicated. In a specific community, it is its own line, but the backbone is basically renting telecommunications, Netcom, Tietong, and the network! So it's not about restricting mutual visits.
At present, there are only three major operators in China:
China Telecom (CDMA formerly Unicom, now sold together with Telecom, called Tianyi); China Unicom (GMS+ Netcom fixed line, Netcom merged into Unicom); China Mobile (GMS+ Tietong fixed line, Tietong merged into mobile).
At present, the services that can provide public broadband access are: Telecom, Netcom, Tietong, Radio and Television, China Unicom and Satcom. Other small businesses are basically rented from above.
