The Ericsson W20e, W21 and W25 support 1.8 and 3V SIM while the Ericsson W20a only supports 3V SIM. 2.3 Wireless LAN (WLAN) Interface The W2x terminals act as wireless Access Point (AP) supporting IEEE 802.11b/g standards. IEEE 802.11b operates in the unlicensed 2.4 GHz band and can theoretically achieve 11 Mb/s. Practical throughput, ranges from ~7 Mb/s (using UDP) to ~6 Mb/s (using TCP). IEEE 802.11g operates in the same band as 802.11b and has a theoretical top speed of 54 Mb/s. In
