The default values of AS923_FREQ_OFFSET are chosen to minimize their 1450 total number and cover a large number of countries. Four different groups are defined below 1451 according to the AS923_FREQ_OFFSET default value. 1452 Group AS923-1: AS923_FREQ_OFFSET default value = 0x00000000, 1453 AS923_FREQ_OFFSET_HZ = 0 .0 MHz 1454 This group is comprised of countries having available frequencies in the 915 – 928 1455 MHz range with common channels in the 923.0 – 923.5 MHz sub-band. These are the 1456 "historical" AS923 countries, compliant to the RP2-1.0.0 specification and previous 1457 versions. 1458 Group AS923-2: AS923_FREQ_OFFSET default value = 0xFFFFB9B0, 1459 AS923_FREQ_OFFSET_HZ = -1.80 MHz 1460 This group is comprised of countries having available frequencies in the 920 – 923 1461 MHz range with common channels in the 921.4 – 922.0 MHz sub-band. 1462 Group AS923-3: AS923_FREQ_OFFSET default value = 0xFFFEFE30, 1463 AS923_FREQ_OFFSET_HZ = -6.60 MHz 1464 This group is comprised of countries having available frequencies in the 915 – 921 1465 MHz range with common channels in the 916.5 – 917.0 MHz sub-band. 1466 Group AS923-4: AS923_FREQ_OFFSET default value = 0xFFFF1988, 1467 AS923_FREQ_OFFSET_HZ = -5.90 MHz 1468 This group is comprised of countries having available frequencies in the 917 – 920 1469 MHz range with common channels in the 917.3 – 917.5 MHz sub-band. 1470 There are no other specific default settings for the AS923 band. 1471 1472
