There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF.
- 1x Raspberry Pi board
- 1x RHF0M301 LoRa Gateway based on Semtech SX1301
- 1x RHF4T002 adapter for Raspberry Pi and RHF0M301
- 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz
- 3x RHF76-052 STMicro STM32L0 + Semtech SX1276 module
- 1x USB to UART adapter
- 1x 4- pin dual female splittable jumper wire
- 1x SD Card
- 1x Adapter
- 3x USB cables
- 1x Ethernet cable
- 2x Antenna
So that’s looks like a complete kit to get started with LoRaWAN using the Raspberry Pi boards, and several RF modules powered by Semtech solutions as most competitors do. The main downsides right now are that it does not seem available for sale (even in China), and the Wiki is password protected. The company website also points to OpenLORA and LPWAN IoT technology forums, where it might eventually be possible to get support about the kit, and other IoT products. Some minimal information can be found in the setup guide.
I’m expecting more information on RisingHF IoT Discovery page, and the opening of the Wiki once the product is launched. [Update: The kit is sold for $385 US (FOB Shenzhen). Sadly, the company only opens the Wiki to people who purchase the kit]
Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011.

It is surprising how much adoption lora is getting.
Things seems to be going well for LoRa. Why is it surprising? Are other alternative better solutions in practice?
I got an answer from the company:
I’ve added the “product brief”, actually more like a setup guide in the post.
Just unexpected to see so much support for a proprietary standard by a single silicon vendor which has small data rates, potential capacity issues if widely adopted, and isn’t dirt cheap. The narrowband market is the alternative, but it seems more fragmented.
The narrowband market seems to be focusing around Sigfox which provides seamless coverage in 21 countries already.
In terms of market offering it’s LoRaWAN that actually seems too fragmented, each country, even each city seems to be getting it’s separate network and there are already 100s to pick from, some commercial, some free. Good luck creating a product around that technology to do something a useful, easily, for end users across the world.
Link Labs has a LoRa gateway board too, with built in GPS and no need for adaptor board, it is raspberry pi HAT compatible
Or you can follow my tutorial to make a even cheaper LoRa gateway
Actually you should be able to do a Lora receiving station on one channel (to start with) with a simple RTL-SDR dongle. Those Semtek chips have different 3 channels for reception, but you should be able to do the same with 3 RTL-SDRs:
Lora is mostly a patented “standard” with one vendor, and Semtek is becoming the Microsoft of IOT.
For a LoRaWAN gateway have a look at https://shop.thethingsnetwork.com/index.php/product/the-things-gateway/
It’s hard to beat the value – it’s a full LoRaWAN gateway with everything you need Antenna, WiFi, and even has nice extras like Bluetooth on top – ready to connect out of the box (and shipping soon) and join (optionally of course) the Things Network which is, even before the official launch, probably the biggest free LoRa network.
Yes there is sigfox if you want a fee-based network provider, but nb-iot seems like it will have more support in that role. But if you want to manage your own network or use a public or shared network lorawan is designed to let you pair end nodes to any network. Though that is what could lead to capacity/density issues. So it would be nice to have an open narrowband solution with hundreds of available channels to run private networks on in unlicensed bands and supported by multiple groups and vendors.
