RedPort MCG-101

An intelligent PBX solution using Iridium to operate as a telephone, Internet portal, GPS device and SMS terminal.


RedPort MCG-101 and MCG-101MW

The MCG-101 provides a reliable and versatile Iridium communications system to remote land, aviation and maritime needs. The system presents an intelligent solution using the Iridium satellite network to operate as a universal communications hub, low-bandwidth internet gateway, and intelligent GPS device, allowing you to send and receive data and voice, and also connect to other devices through RS232 and ethernet.

The MCG-101 was designed and built using 100% digital technology. This enables the system to provide clear, true to life audio, and eliminates any internal echo problems. For external interface portions of the system, such an analog POTS telephone, echo cancellation is performed by a hardware echo canceler.

The MCG-101 can be used in a number of scenarios for both stationary and mobile needs, from enabling remote command posts, providing redundant communications infrastructure for operations bases, to enabling voice and data communications within vehicles or vessels, regardless of proximity to standard systems and telecom towers.

MCG-101 for First Responders

Reliable Communications. Anywhere.


Feature Functionality for the MCG-101 is extensive, and includes all forms of communications transmission and receiving, enabled by a number of different connection types.


You can connect any standard analog telephone directly to the MCG-101 and start using the Iridium network. All of your calls are digitally processed for the best quality. For all satellite telephony products, we recommend the use of SatCollect to reduce costs and operate with a local phone number.

GPS Tracking

The MCG-101 contains an embedded GPS receiver for GPS tracking, with 20 channels, -159dbm sensitivity, and a 2 meter accuracy. Best of all, the GPS receiver shares a single antenna with the Iridium modem, so installation is simple.


Connecting your computer to the Internet is as simple as plugging it in. Just connect your computer and go online, and the MCG-101 will automatically connect to the Internet for you. You can also configure the MCG-101 via the ethernet port.


Connect via Wi-Fi to enable phone calls directly from your mobile phone.


USB port for expansion to connect external peripherals.

SIM Card

The MCG-101 has an external SIM card slot which makes installing or changing the SIM card fast and simple.

Voice Capabilities

Connect any standard analog telephone or any SIP capable phone to the MCG-101 and you can start making phone calls. Digital audio processing gives you the best audio quality, and with Iridium, you can call from anywhere to anywhere in the world.

Data Capabilities

Connect to the Internet at 2.4K
Connect to RUDICS for custom applications
Short Burst Data for small messages
Ethernet for automatic dialup
Serial port for legacy modems or applications


The MCG-101 is a fully capable processing platform that can be easily configured for custom call routing, data applications, and special projects. The system features a full PBX that can run an entire office, and run custom software as well. An SDK is available allowing you to develop your own solutions for complex projects. By using the MCG-101 as a standard platform, the development time is shortened, allowing you to deliver finished solutions to your customers fast.

MCG-101 for Enterprise

Keep Personel and Assets Connected. Anywhere.
