The Mobile Network Operators (MNOs) such as Vodafone and EE use an entirely separate set of networks for their services compared to Wi-Fi and computer networking. On an event site devices such as mobile phones can use any onsite Wi-Fi for data but not natively for their calls. Some operators are now releasing applications which facilitate this but it depends on the operator and specific contract. The coverage and capacity of the mobile networks on an event site is entirely controlled by the mobile operators and there is no legal way to improve this without their assistance.
