Abstract

A portable access point comprises a wireless LAN transceiver that selectively establishes a plurality of Ethernet wireless links with a plurality of wireless client devices, respectively. A wireless WAN transceiver establishes an Ethernet data connection with an Internet Service Provider (ISP), receives and forwards Ethernet data packets from at least one of said wireless client devices to said ISP and receives and forwards Ethernet data packets from said ISP to said one of said wireless client devices. A routing device routes Ethernet data packets between said wireless LAN transceiver and said wireless WAN transceiver. A control module controls operation of said wireless LAN transceiver and said wireless WAN transceiver. A first storage device stores operating system and application instructions for said control module.
