EDR 900: Event Driven Radio

EVENT DRIVEN RADIO
900MHZ TRANSCEIVER
DESCRIPTION
The event driven radio offers a superior low cost wireless solution
for applications with stringent battery life time requirement. The
transceiver operates at 900MHz ISM band. Thus applications can
further benefit from longer communication distance with a
minimum power budget.
To achieve ultra low power consumption, the receiver is based on
envelope detection to avoid many power consuming blocks, such as
VCO and PLL. A unique two-tone modulation architecture is
adopted to overcome the drawback (limited selectivity) inherent to
this type of envelope detector based architectures. Therefore, good
interference robustness is remained in this ultra low power design.
To cater for application scenarios with different power budget and
communication distance requirements, the receiver is highly
configurable.
There are four RF gain modes, which leading to the active power
consumption ranging from 65 to 150 μW.
Corresponding variety in sensitivity levels covers communication
distance from a few meters to hundreds of meters in a most efficient
way.

The event driven radio offers a wireless link
solution with state-of-the-art lowest power
consumption, catering for low data rate, short to
long distance communication.
The configurable receiver consumes less than 150
μW active power enabling latency sensitive
communication.
Configurable operating modes cover different
application needs with different power budgets.
Complete evaluation kit offers flexibility to
application development building on this radio
solution.

EVALUATION KIT
To offer the end user high flexibility in developing applications
based on this ultra low power radio, an evaluation kit can be
provided. This evaluation kit integrates transmitter and receiver
event driven radio chips, FPGA where the baseband runs, and
microcontroller on the same PCB board. Users can easily define and
develop their own application stacks on top of the radio, which
means MAC layer and/or above. It is also possible to connect this
evaluation kit to other sensor interfaces. This kit helps a quick
development of an application demonstration.

APPLICATION SETUP EXAMPLE
Typically the radio can be adopted in one of the two setups:
O
Transceiver as a standalone radio solution. The event
driven transceiver offers an ultra low power wireless
solution for a low data rate communication (≤100kbps),
such as remote control, tracking, and monitoring.
O
Ultra low power receiver to assist another high
performance radio as dual radio solution to

The event driven receiver is operating as a wake up receiver. It
detects the event, and wakes up the high performance main
radio. The dual radio system is suitable for applications with very
low power budget, high data rate, and stringent latency
requirement.
