Short Range Devices

Short Range Devices (SRD) are radio devices that offer a low risk of interference with other radio services, usually because their transmitted power, and hence their range, is low.

Short Range Devices are used for a vast amount of applications, e.g.:

Short-range devices in most cases operate on a license exempt basis. Generaly, they share spectrum with another (primary) radio service. Short Range Devices generally may use the band on the basis of two conditions:

There are a number f bands used for Short Range Devices. The primary bands that are available globally, are the 13,56 MHz (mainly used for RF ID), 40 MHz, 433 MHz, 2.4 GHz and 5.8 GHz band.
