Drivers
The CC1100/CC1101/CC2500 radios are pin and driver compatible. Dual-radio platforms are easily achievable.
Range vs. Frequency
The lower the frequency, the longer the range. The CC1100 sports the lowest frequency.
Frequency vs. Antenna Size
The lower the frequency, the larger the antenna. The 2.4 GHz radios, CC2500 and CC2420, require the smallest antenna.
Throughput vs. Current Consumption
The higher the throughput, the less energy it takes to transmit the data. In terms of raw throughput, the CC1100 and CC2500 can be more energy efficient than the fixed-rate throughput of the CC2420. However, at a lower throughputs, the maximum current consumption decreases. Although the maximum current consumption decreases (helping you match to a particular battery better), the total energy consumption increases because it takes longer to send the same amount of data.
Throughput vs. Range
The CC1100 and CC2500 can decrease their throughput to achieve longer range. With the CC1100 radio at 315 MHz, for example, we've achieved a maximum of ~700-800 feet transmission range on the ground.
Accessories
- The CC2420 includes hardware AES-128 encryption.
- The CC1100 and CC2500 include hardware Wake-on-Radio (low power listening) functionality.
