Product Description

The GDCA05 is an SRM serial wireless modem that provides the highest level of reliability for antenna serial data transmission.  It works well in any mode, such as point-to-point wireless bridges, point-to-multipoint and interrupter modes, making it ideal for short and long distances in the harshest industrial environments.

Nowadays, the demand for wireless modems is gradually increasing. In order to ensure cost-effective and reliable manner ways of transmitting data in the form of voice and video, infrastructure with less modem requirements is used to facilitate communication.

Multi-modem wireless modem
