Connectivity

Arm-based hardware enables IoT devices to talk to each other and transmit critical information either to the cloud or between devices.

Choose the appropriate connectivity protocol and access resources for your application.

Wi-Fi is one of the primary protocols used for internet communication. At 5GHz radio bands, Wi-Fi provides the highest speed of any standard. Because of the amount of power that it uses, Wi-Fi is typically used in gateways.

Bluetooth Low Energy (BLE) allows devices to communicate over short, physical distances with reduced power consumption compared to classical Bluetooth.

LongRange (LoRa) connectivity protocol allows IoT devices to communicate short messages over long distances with low power consumption. LoRa is the physical layer protocol as defined by the Open Systems Interconnection (OSI) seven-layer network model. This means that LoRa implements communication at the bits level. The related LoRaWAN protocol sits on top of LoRa. LoRaWAN sits at the data packet level of the stack, and allows low-power devices to communicate with internet connected devices over long ranges.

LTE-M enables your IoT device to send data like sensor readings or geolocation to the cloud using low power consumption. LTE-M is a cellular communication protocol that allows your IoT device to send information without any additional infrastructure. To use LTE-M, you need to have cellular LTE coverage in your region.

Zigbee is designed to carry small amounts of data at speeds of up to 250kbps, and over a short distance in a mesh network topology. Zigbee is ideal for many IoT applications.

NarrowBand-IoT (NB-IoT) enabled devices are typically used in rural or remote environments since they can last up to ten years on a single battery and can penetrate concrete surfaces of up to three meters.
