For proprietary solutions (non-IEEE 802.15.4), the RF transceiver can be programmed in

steps of 1 MHz.

The output power level can be configured from the firmware in the range -25 to 0 dBm.

The RF transceiver uses direct sequence spread spectrum (DSSS) with 2 Mchip/s chip rate,

giving a raw data rate of 250 kbit/s. The modulation format is Offset – Quadrature Phase Shift

Keying (O-QPSK). The DSSS makes the communication link robust in noisy environments

when sharing the same frequency band with other applications.

The use of RF frequencies and maximum allowed RF power is limited by national regulations.

The RC2200 series is complying with the applicable regulations for the world wide 2.45 GHz

ISM band.

Specifically it complies with the European Union R&TTE directive meeting EN 300 328 and

EN300 440 class 2. It also meets the FCC CFR47 Part15 regulations for use in the US and

the ARIB T-66 for use in Japan.
