Application note
Using the BlueNRG transceiver under FCC title 47 part 15
in the 2400 – 2483.5 MHz band
By Placido De Vita
Introduction
The BlueNRG is a very low power Bluetooth low energy (BLE) single mode network
processor, compliant with Bluetooth specifications core V4.0. 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’s 79 channels in the 1 MHz band, low energy technology has 40 channels (37
data channels + 3 advertising channels) in the 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 transmitting power is 10 mW. 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
FCC title 47 part 15 [2] in the 2400 to 2483.5 MHz band.
For details on the regulatory limits in the 2400 - 2483.5 MHz frequency band, please refer to
the FCC title 47 part 15 regulations [2]. These can be downloaded from
