RAK Wireless Introduces Feature-Rich LoRa Gateway Kits

With the rise of the Internet of Things came the ability for devices to interact and exchange data. Currently, the majority of these devices operate in the 2.4GHz ISM band — the same frequency band Wi-Fi operates in. Additionally Bluetooth, microwave ovens, and almost any device labeled as “smart” are all blasting away signals at 2.4GHz. This is mainly due to the fact that operation in the ISM bands are free. Indeed, most frequencies require a license to operate in and are all regulated by the Federal Communications Commission (FCC). The drawback of operating at 2.4GHz is that communication range is limited due to propagation loss. In fact, the additional Wi-Fi band, 5.8GHz, suffer even more severe propagation loss due to the higher frequency.

Propagation loss of the Wi-Fi ISM bands highlighted the need for a means of longer range communication for smart devices. These can be smart sensors and devices in remote and rural locations. Out of this need, LoRa was born. LoRa is an acronym for “long range.” It is a patented technology currently owned by Semtech. (Read more about LoRa after this link.) To make longer range communication possible, it uses a mix of proprietary technology as well as lower operating frequencies. At the time of this writing, LoRa is making use of free sub-gigahertz frequency bands at 433MHz, 868MHz, and 915MHz.
