Few Internet providers Built in wifi in wimax modem(Device) , few provides a separate box pack wifi router which attaches with normal wimax modem.
If someone wants to know which one is better , answer would be EQUAL. There is no difference in wifi quality if both are reliable brand. Requirement makes difference, If a customer wants to use multiple connection on 1 wifi then his choice must be a WIFI ROUTER with normal device. So he can attach multiple connection in router. Same router even works on different connection if customer unplug the ISP connection who provided him the wifi router.
On other side builtin wifi with wimax device only works with that particular ISP who installed this connection.
It's a single unit so only one power will work both Internet + WiFi. For using multiple internet connection on that wifi + wimax device required complexed configuration.
Qubee gives WiFi router in Rs. 1200/- (As per December 2012 Tariff).
Wi-Tribe gives WiFi Device with additional Rs. 1500/- (As Per December 2012 Tariff)
