Frequency hopping NO.: 40 channels will be used in a select group of channels 12、Power DC 1.5V*4 cell ”AA” alkaline battery frequency hopping spread spectrum (FHSS) system works by hopping from one frequency channel to another in a unknown sequence out of a select group of channels. The system frequency hops between 40 channels. If it is determined that one of the 40 hopping channels is found to be noisy or poor due to other RF interference, then a new channel is selected from the 40 unused channels, This repeats whenever a noisy or poor channel is detected,.The sequential hops is no any order can follow, is completely random. Pseudorandom Frequency Hopping Sequence Table as below: Channel: 08, 24, 40, 26, 42, 09, 01, 33, 41, 35, 23, 43, 19, 06, 22, 04, 20, 36, 38, 46, 50, 28, 21, 29, 10, 44, 15, 13 etc. The system receiver have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shift frequencies in synchronization with the transmitted signals. 13 、Channel List Channel List Channel Frequency (MHz) Channel Frequency (MHz) Channel Frequency (MHz) 01 2405 18 2422 35 2439 02 2406 19 2423 36 2440 03 2407 20 2424 37 2441 04 2408 21 2425 38 2442 05 2409 22 2426 39 2443 06 2410 23 2427 40 2444 07 2411 24 2428 41 2445 08 2412 25 2429 42 2446 09 2413 26 2430 43 2447 10 2414 27 2431 44 2448 11 2415 28 2432 45 2449 12 2416 29 2433 46 2450 13 2417 30 2434 47 2451 14 2418 31 2435 48 2452 15 2419 32 2436 49 2453 16 2420 33 2437 40 2454 17 2421 34 2438 51 2455
