With thousands of beacons in field, monitoring for their battery levels and replacing them as battery drains can be a significant undertaking. It is therefore desirable to use beacons with longer battery life.īeacons are small battery powered devices. The backend cloud server processes the information and performs further analysis guiding specific location based behaviors in the mobile device.īeacons consist of four primary components which we detail below: The signal is picked up by the phone, and often transmitted to a cloud server via the internet. The hardware consists of a microcontroller with a Bluetooth LE radio chip and a battery. New radio chips are optimized for Bluetooth LE, whereas older versions were designed for Bluetooth Classic which had higher power consumption. #Battery type for radbeacon dot Bluetooth The radio chip is commonly manufactured by two major companies: 1) Texas Instruments and 2) Nordic Semiconductor. These batteries are dense Lithium Ion cells and provide up-to 1,000 mAh of stored power in a very small form factor.Ĭompanies such as BlueGiga and Gimbal use the underlying hardware from Texas Instruments (TI) but with their custom firmware before selling them to beacon vendors.Ĭoin cell batteries are the most popular choice for most beacons. Commonly available coin cell sizes are 240 mAh (CR2032, small size), 620 mAh (CR2450, medium size) and 1,000 mAh (CR2477, large size). Coin cell batteries are otherwise commonly used in key fobs and digital watches. Some beacons also use Alkaline AA batteries, which are commonly used in digital cameras and TV remotes. A typical AA battery provides around 2,000 mAh power but at a significantly larger size than coin cell batteries. Lastly, some beacons are externally powered. They can be installed in a wall outlet or a USB outlet. #Battery type for radbeacon dot Bluetooth.#Battery type for radbeacon dot android.
