Abstract: A wireless communication system, a communication method, and a portable transceiver device are provided. The wireless communication system includes a server, a plurality of gateway devices and user-end portable transceivers that are interconnected by a wireless WAN protocol, e.g. LoRa. Each portable transceiver connects a user device via a near-end wireless communication protocol that allows the user device to connect with the server via a gateway device. After the user device sends a message through the portable transceiver, the server discovers another portable transceiver and another gateway device according to a destination address. Thereby, the message can be transmitted via this connection, or a direct voice communication can be performed via a communication channel over this connection. The communication system therefore provides a communication service under the wireless WAN protocol that is an alternative to traditional mobile communications.
