Why use high bit rate for low rate applications?
Works from 100Kbps to 1Mbps
Improved Robustness and Coexistence
128 bits are transmitted in 128Sec
Capable to receive an ACK and retransmit twice within a single Bluetooth hop
Low latency
Lower power consumption
Shorter transceiver on time
As long as the cost is low…

Power Consumption
Peak current consumption of the radio module is 23mA
This includes full cycle of transmitting or receiving at 1Mbps
Transmitting or Receiving 1Kbps at 1Mbps bit rate results in 23A current consumption
No standby current, Wakeup time of 10Sec
Operating voltage of 2.7-5V improvable to 1.5V

Cost
Due to cellular technology – SAW is a mainstream process
5mm2 of SAW – one mask process
1.3mm2 of silicon (Bi-Polar or CMOS process)
Simple module architecture
