¿What is a "Fixed Wireless Terminal"?

A Fixed Wireless Terminal (FWT) is best described as a base station mobile phone. It enables connection of landline devices such as a telephone handset, call control devices like the ZSSMX5, fax machine, etc., and connects using the mobile phone network. Being completely wireless, a Fixed Wireless Terminal is often used in situations where traditional landline infrastructure is not available. The unit takes any standard mobile device SIM card and sends all calls over the corresponding cellular network, allowing users to make voice calls using any standard handset or landline device.
