Powerful Antennas For Maintaining Stable Networks

GL-X300B-GPS is equipped with five external antennas, including two 2.4GHz Wi-Fi, two 4G LTE, and one GPS Antenna. The extendable wired antennas are perfect for having multiple reception placements within a vehicle, minimizing reception black spots when traveling through high network density cities.

GL-X300B-BLE is equipped with three external omnidirectional antennas for 2.4GHz Wi-Fi, 4G LTE, and BLE communication, receiving signals from all directions, and providing high flexibility in installation placement within an industrial environment.

For Wall Mounted Applications

Collie's mounting platform has screw slots for wall mounting in an industrial environment, conveniently deploy the device in a safe position with minimal physical interference for reliable wireless connection.

For DIN Rail Mounted Applications

Collie's mounting platform is conveniently designed to fit in a DIN rail along with other electrical equipment, simplifying the deployment of an organized wiring design within an electrical enclosure or in other industrial environments.


Securing Your Internet In The Background

Collie (GL-X300B) is pre-installed with OpenVPN and WireGuard® supporting 30+ VPN services. It automatically encrypts all network traffic within the connected network, including guest devices and client devices that are not capable of running VPN encryption. Collie (GL-X300B) can also act as a VPN server, redirecting traffic from client devices in remote locations to the VPN server via a VPN tunnel before accessing the public internet.

WireGuard® is a registered trademark of Jason A.Donenfeld.
