Etross GSM-188B is a Fixed Wireless Terminal designed to provide better wireless connectivity between POTS (plain old telephone set) and existing GSM 850/1900Mhz (or 900/1800Mhz) network with high sensitivity to receive signal and large transmitting power to expand extensively the effective coverage of GSM service. It can be used not only in communication for vehicles such as automobiles, trains, floating vehicles, etc., but also in communication for construction sites, isolated islands and rural areas where hardwire-line telephone service is unavailable. So they are widely used in home &office, public phone, rural areas, steamer, railway etc.
