Reliance provides two main ways for employees to connect to the office while mobile: data cards and fixed wireless phones/terminals. Both connect to the internet or a VPN for access to office servers. Reliance's wireless network covers most of India, providing uninterrupted connectivity even in remote areas at speeds up to 144 kbps. Customers can use their mobile phone as a modem. The VPN option (WDVPN) uses MPLS networking to securely connect remote locations and mobile users to central offices. Case studies show banks and lottery companies using over 100 and 19,000 WDVPN connections respectively across multiple cities.
