6.5 Energy Detection (ED)
The Energy Detection (ED) module is characterized by:
? a dynamic range of 87 dB
? a resolution of about 1 dB
? a measurement time of 8 symbol periods for IEEE 802.15.4 compliant data rates
6.5.1 Overview
The receiver ED measurement (ED scan procedure) can be used as a part of a channel
selection algorithm. It is an estimation of the received signal power within the bandwidth
of an IEEE 802.15.4 channel. No attempt is made to identify or decode signals on the
channel. The ED value is calculated by averaging RSSI values over 8 symbol periods,
with the exception of the High Data Rate Modes (refer to section 7.1.4).
6.5.2 Measurement Description
There are two ways to initiate an ED measurement,
? manually by writing an arbitrary value to register 0x07 (PHY_ED_LEVEL), or
? automatically after detection of a valid SHR of an incoming frame.
Manually:
For manually initiated ED measurements, the radio transceiver needs to be
either in the state RX_ON or BUSY_RX. The end of the ED measurement time
(8 symbol periods) is indicated by the interrupt IRQ_4 (CCA_ED_DONE) and
the measurement result is stored in register 0x07 (PHY_ED_LEVEL).
In order to avoid interference with an automatically initiated ED measurement,
the SHR detection can be disabled by setting register bit RX_PDT_DIS
(register 0x15, RX_SYN), refer to section 7.2.
Note that it is not recommended to manually initiate an ED measurement when
using the Extended Operating Mode.
Automatically:
An automated ED measurement is started upon SHR detection. The end of the
automated measurement is not signaled by an interrupt.
When using the Basic Operating Mode and standard compliant data rates, a
valid ED value (register 0x07, PHY_ED_LEVEL) of the currently received frame
is accessible not later than 8 symbol periods after IRQ_2 (RX_START) plus a
processing time of 12 μs. For High Data Rate Modes (refer to 7.1.4), the
measurement duration is reduced to 2 symbol periods plus a processing time of
12 μs. The ED value remains valid until a new RX_START interrupt is
generated by the next incoming frame or until another ED measurement is
initiated.
When using the Extended Operating Mode, it is useful to mask IRQ_2
(RX_START), thus the interrupt cannot be used as timing reference. A
successful frame reception is signalized by interrupt IRQ_3 (TRX_END). In this
case, the ED value needs to be read within the time span of a next SHR
detection plus the ED measurement time in order to avoid overwrite of the
current ED value.
