Presentation by Andy Gowans on the EN 301 893 Harmonised Standard. Expect BRAN 32.5 in April to process comments
EN Annex D DFS parameters
Channel Availability Check 60s ‘continuous checking’ in probabilistic terms
Channel Move Time 10s
Channel Closing Transmission Time 220/260 ms ? still in discussion [the key item being measured]
99.99% probability of detection
Question about radar bandwidth of their signal – look in HS and ITU-R 8A documents
Examples of slave devices and radar detection thresholds:
Maximum transmit power
Example 1:
Slave device tx
➢ 200mW, –64 dBm
➢ 200 mW, -62 dBm
121-200mW, -55 dBm
< 120 mW, N/a
Example 3:
➢ TX >500mW, –62 dBm
➢ 201-500 mW, -62 dBm
➢ 101-200 mW, -55 dBm
➢ 51-100 mW, -52 dBm
➢ < 50 mW, n/a
Ad hoc networking threshold:
➢ 200mW, -64dBm
➢ 26-200 mW, -62 dBm
➢ < 25 mW, n/a [same in 5.8 GHz band]
➢ Radar detection is not mandated in 5150-5250
HS will have startup test
