Popular IoT Protocols
The Internet of Things (IoT) is a network of physical objects such as sensors, actuators, and devices that are connected to the Internet. These devices communicate with each other and with the cloud to provide various services to users. To enable this communication, several IoT protocols have been developed so far, each with its own unique features and characteristics. In this blog post, we will explore five popular IoT protocols: Bluetooth, BLE, ZigBee, Thread, LoRa, LoRaWAN and LTE-M.

60GHz Regulations in Canada
Wi-Fi, as most of us know, operates on the 2.4GHz or 5 GHz band. But there are, actually, others 802.11 protocols utilizing other frequency bands (900MHz, 60GHz,…). Today, we will be talking about the regulations of using the 60GHz frequency band in Canada. This band is used for the 802.11 protocols known as 802.11ad (now 802.11-2016 Clause 20) and 802.11ay.
