Considerations

and

Guidelines

14.31.1 SRD regulations

International regulations and national laws

regulate the use of radio receivers and

transmitters. SRDs (Short Range Devices)

for license free operation are allowed to

operate in the 2.4 GHz band worldwide.

The most important regulations are ETSI

EN 300 328 and EN 300 440 (Europe),

FCC CFR-47 part 15.247 and 15.249

(USA), and ARIB STD-T66 (Japan).

14.31.2 Frequency hopping and multi-

channel systems

The 2.4 GHz band is shared by many

systems both in industrial, office and home

environments.

CC2430

uses

direct

sequence spread spectrum (DSSS) as

defined by [1] to spread the output power,

thereby making the communication link

more robust even in a noisy environment.

With

CC2430 it is also possible to combine

both DSSS and FHSS (frequency hopping

spread spectrum) in a proprietary non-

IEEE 802.15.4 system. This is achieved by

reprogramming the operating frequency

(see

the

Frequency

and

Channel

Programming section on page 183) before

enabling

TX.

frequency

synchronization scheme must then be

implemented within the proprietary MAC

layer to make the transmitter and receiver

operate on the same RF channel.

14.31.3 Data burst transmissions

The data buffering in

CC2430 lets the user

have a lower data rate link between the

CPU and the radio module than the RF bit

rate of 250 kbps. This allows the CPU to
