I have 36 Raspberry Pi’s 3 new in the box that we have left over from a project. Willing to sell them at 50% off regular price. Let me know if anyone wants them.
In the US, there is an unregulated band at ~ 900Mhz that was used by early cordless phones. It has been of interest recently for iOT for 3 reasons: Longer distance, better penetration, and in an unregulated band (you don’t need a FCC license when deploying)

We did a bunch of investigation for longer range and better penetration. It was pretty clear early on that lower frequencies gave better distance and better penetration.

We also found that Bluetooth signals were heavily attenuated if other objects are nearby (furniture, clothing, products on shelves). So the range for Bluetooth was not 150ft but was more like 75 ft.

Both mesh and repeaters made deployment difficult since it required an AC outlet between the sensor and our bridge (battery power is hard since the devices have to be continually on).

#LoRaWAN
We developed a bluetooth “repeater” that would repeat the bluetooth signal to extend the range, but since those devices had to be listening all the time, they required AC power. We also looked at mesh.

We learned a lot in the trials and uncovered a large need: range. Bluetooth is great for inexpensive sensors that are battery powered, but the range of 150 feet or less is problematic when deploying.

We developed a line of bluetooth call buttons, motion sensors, and other sensors to detect when customers “dwell” in an area. We did successful trials at large office supply chains, box stores, supermarkets, and others.

#LoRaWAN
We started getting inquires from other customers to detect proximity without requiring customers to install an app (this was the major roadblock to larger adoption for iBeacons).

We have deployed (and are currently selling) beacons to large customers in the retail and home automation space. Our SDK is integrated into customers’ iOS apps that do the deployment locally. Customers love it.

Back in 2013, Apple released the iBeacon spec and support for iBeacon in iOS. It gave an amazing way to detect proximity on your iPhone. We developed a line of beacons that made it easy to deploy and manage a fleet of beacons without a cloud service.

Heading off to CES and wanted to give a bit of background on what my team and I have been working on/why I am heading to CES for the first time with a new LoRaWAN/Bluetooth devices in tow. This thread is a bit long so hold on.

#LoRaWAN
Our CEO Tim Perfitt @TPerfitt will be in Las Vegas at #CES2018 to meet with customers and partners about Proxidyne hardware, software & services in #IoT, #LoRaWAN, #Bluetooth, #iBeacon & #buttons.
