A portable wireless network gateway aggregates bandwidth demand of different devices operating under different communications protocols. Network connectivity is provided by encapsulating data from the different devices to make the data appear to be data native to a single network. For example, the single network is a cellular wireless network. The different communications protocols include but are not limited to IEEE 802.11, IEEE 802.3, USB, cellular wireless protocols, Bluetooth, RS-232, and IEEE 11.1R.
