Update Sri Lanka regulatory domain based on the RTTE Type Approval Rules 2020 from the Telecommunications Regulatory Commission of Sri Lanka (TRC). Source: https://www.trc.gov.lk/content/files/licensing/RTTE_GAZETTE-English.pdf Key changes: - Change DFS region from FCC to ETSI (document references ETSI standards EN 300 328 and EN 301 893 as the applicable radio interface standards) - 2.4 GHz: expand to 2400-2483.5 MHz at 23 dBm - 5150-5250 MHz: 23 dBm with DFS - 5250-5350 MHz: 20 dBm with DFS (no TPC, 3 dB reduction per EN 301 893) - 5470-5725 MHz: 27 dBm with DFS (no TPC, per EN 301 893) - 5725-5875 MHz: 24 dBm with DFS (per ETSI EN 302 502) Note: The TRC gazette conflicts internally by allowing 30 dBm for 5725-5875 MHz while citing EN 301 893 (which doesn't cover this band). Lacking TRC clarification, we conservatively default to the ETSI EN 302 502 limits (24 dBm). Signed-off-by: Mohamed Aashif --- Thanks for the review and catching the TPC and ETSI standard details! Changes in v2: - Split 5150-5350 MHz into 5150-5250 MHz (23 dBm) and 5250-5350 MHz (20 dBm), adding AUTO-BW to both. - Applied a 3 dB reduction to 5250-5350 MHz and 5470-5725 MHz (now 27 dBm) to comply with ETSI limits since TPC is unsupported. - Capped 5725-5875 MHz at 24 dBm per ETSI EN 302 502. db.txt | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) diff --git a/db.txt b/db.txt index fdc2c13..12cdafd 100644 --- a/db.txt +++ b/db.txt @@ -1058,12 +1058,15 @@ country LI: DFS-ETSI # 60 GHz band channels 1-4 (ETSI EN 302 567) (57000 - 66000 @ 2160), (40) -country LK: DFS-FCC - (2402 - 2482 @ 40), (20) - (5170 - 5250 @ 20), (17) - (5250 - 5330 @ 20), (24), DFS - (5490 - 5730 @ 20), (24), DFS - (5735 - 5835 @ 20), (30) +# Source: +# https://www.trc.gov.lk/content/files/licensing/RTTE_GAZETTE-English.pdf +# Sri Lanka RTTE Type Approval Rules 2020, Table 2 - Wideband Data Transmission +country LK: DFS-ETSI + (2400 - 2483.5 @ 40), (23) + (5150 - 5250 @ 80), (23), DFS, AUTO-BW + (5250 - 5350 @ 80), (20), DFS, AUTO-BW + (5470 - 5725 @ 160), (27), DFS + (5725 - 5875 @ 80), (24), DFS # Source: # http://lca.org.ls/images/documents/lesotho_national_frequency_allocation_plan.pdf -- 2.54.0
