Application note

Using the BlueNRG transceiver under ETSI EN 300 328

in 2400 – 2483.5 MHz band

By Ugo Raia

Introduction

BlueNRG is a very low power Bluetooth low energy (BLE) single mode network processor,

compliant with Bluetooth specifications core 4.0. The BlueNRG can act as master and

slave.

Bluetooth low energy technology operates in the same spectrum range (2400 - 2483.5 MHz,

ISM band) as classical Bluetooth technology, but uses a different set of channels. Instead of

Bluetooth technology's 79 channels of 1 MHz band, the low energy technology has 40

channels (37 data channels + 3 advertising channels) of 2 MHz band. Within the channel,

data is transmitted using GFSK (Gaussian Frequency Shift Modulation). The bit rate is 1

Mbit/s, and the maximum transmit power is 10 mW (10 dBm).

Further details are given in volume 6 part A of the Bluetooth Core Specification V4.0.

This application note outlines the expected performance when using the BlueNRG under

ETSI EN 300 328 in the 2400 to 2483.5 MHz band.

For details on the regulatory limits in 2400 - 2483.5 MHz frequency band, please, refer to

ETSI EN 300 328 V1.8.1 (2012-06).
