This is the first winter since we launched the ePMP™ platform, and it has been a particularly rough winter in many regions. Network operators considering deploying affordable ePMP to Connect the Unconnected™ are asking about system performance in harsh cold weather so that they can select a solution that meets their performance expectations.

We use commercial grade parts on all ePMP modules. All of the radios on the market that we have seen that sell below $100 take the same approach. Commercial grade parts are rated to operate between 32° F to 185° F (0° C and 85° C). This is the temperature inside the radio housing, not the ambient temperature surrounding the radio. The other products in our PMP and PTP portfolios utilize industrial grade parts which are rated from -40° F to 185° F (-40° C to 85° C). Check out all of the ePMP modules’ performance specifications:

–  GPS Synchronized Radio
–  Integrated Radio
–  Connectorized Radio

In order to improve the performance of ePMP in cold temperature environments, we added circuitry to the ePMP modules that acts as a heater. This is different from the approach that we have seen in other sub-$100 radios. In addition to the ePMP heater circuitry, there is a small microcontroller on the radio that continuously measures the internal temperature. The purpose of this controller is that if the radio does what is called a “cold start” – powers on when the temperature within the radio housing is too low – the radio will not begin operating until the temperature within the radio reaches acceptable operating temperatures.  We believe that this approach to arming ePMP with what it takes to bear winter’s brunt is unique among the sub-$100 radios on the market and that it will operate better at cold temperatures than other radios.

We are always interested in hearing your stories of how and where you are deploying ePMP to connect the unconnected, and how your network is performing. Send us your stories and photos to Show off Your Network
