Type 1 can create more channels thanks to a more 494 compact description of the additional channels (enumeration vs exact 495 frequencies). In both cases, default channels are not modified with the 496 CFList. Default channels may be disabled with LinkADRReq or 497 modified with NewChannelReq. 498 2.3.2.1 800 MHz Fixed Channel List Definition 499 The 800 MHz fixed channel list defines 40 channels that may be created. Channel-ID 0 is 500 863.1 MHz; channels increase at 200 kHz spacing to Channel-ID 34 at 869.9 MHz. Five 501 additional channels, identified as 35 to 39, are defined at 865.0625 MHz, 865.4025 MHz, 502 865.6025 MHz, 865.785 MHz, and 865.985 MHz respectively. ChMask3, ChMask4, and 503 ChMask5 are RFU. 504 505 The end-device SHALL create an additional channel at the frequency specified by the 506 Channel-ID, numbered sequentially in order of Channel-ID, starting after the last default 507 channel, for each bit set in the CFList. 508 509 These channel definitions represent a superset of common channels in widespread use in 510 EU868, IN865, and RU864. 511 Example: If an end-device uses channel plan EU868, supports CFList 512 Type 1, and receives it equal to 0x0100_A010_0000_0000_0000_0000, 513 then ChMaskGrp0 = 0x0100 and ChMaskGrp1=0xA010. Four bits are 514 set, which correspond to valid channels, so the end-device will create 515 four channels. EU868 has three default channels, so the first created 516 channel will be for ChIndex=3. The end-device will create ChIndex=3 517 at center frequency 863.1MHz, ChIndex=4 at center frequency 518 863.1+21*0.2 = 867.3MHz, ChIndex=5 at center frequency 519 863.1+23*0.2 = 867.7MHz, and ChIndex=6 at center frequency 520 863.1+28*0.2 = 868.7MHz. 521 Note: The frequencies of the three EU868 default channels correspond 522 to ChMaskGrp1 = 0x000E. Setting these bits would create new 523 channels at the same frequency as default channels. 524 The center frequencies of the four RFID channels under ETSI EN 302 525 208 correspond to ChMaskGrp0 = 0x0020, ChMaskGrp1 = 0x4900. 526 Setting these bits would create channels with a higher risk of 527 interference. 528 2.3.2.2 900 MHz Fixed Channel List Definition 529 The 900 MHz fixed channel list defines 96 channels. Channel-ID 0 is 915.1 MHz; channels 530 increase at 100 kHz intervals to Channel-ID 95 at 924.6 MHz. 531 532
