DJF was appointed to provide on-site support for a UK IoT System Integrator for ongoing connectivity issues. Intimate knowledge of cellular module & LoRaWAN packet forwarding behaviour allowed DJF to implement improved configuration leading to higher reliability across the system.

DJF accompanied staff from a well known BMS Company onsite to develop a remote connectivity solution for HVAC control panels installed in the field. The process was tried, tested and documented within a single working day.

"I have had the pleasure of working with David on several M2M and Connected Solutions projects. I was always impressed with his depth of technical knowledge which he was fully able to put in practical terms where it related to my projects. David was also able to see the bigger picture and help guide me beyond the immediate scope of the task at hand"
