RF Frequency, Output Power Levels and Data Rates
The following table shows the RF channels as defined by the IEEE 802.15.4 standard.
RF channel Frequency
11 2405 MHz
12 2410 MHz
13 2415 MHz
14 2420 MHz
15 2425 MHz
16 2430 MHz
17 2435 MHz
18 2440 MHz
19 2445 MHz
20 2450 MHz
21 2455 MHz
22 2460 MHz
23 2465 MHz
24 2470 MHz
25 2475 MHz
26 2480 MHz
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.
