Ezubere usoro Kingtone JIMTOM® Fiber Optic Repeaters iji dozie nsogbu nke akara ekwentị na-adịghị ike, nke dị ọnụ ala karịa ịtọ ntọala ọdụ ọhụrụ (BTS).Isi ọrụ nke sistemu RF Repeaters: Maka njikọ ala, akara sitere na BTS na-enye nri na Master Unit (MU), MU wee gbanwee akara ngosi RF ka ọ bụrụ akara laser wee nye nri na eriri iji bufee na Remote Unit (RU).RU wee gbanwee akara laser ka ọ bụrụ akara RF, wee jiri Power Amplifier mee ka ike dị elu na IBS ma ọ bụ antenna mkpuchi.Maka njikọ elu, Bụ usoro ntụgharị, a na-enye akara sitere na ekwentị mkpanaaka na ọdụ ụgbọ mmiri MU nke MS.Site na duplexer, mgbama na-abawanye site na ụda mkpọtụ dị ala iji kwalite ike mgbaama.Mgbe ahụ, a na-enyefe akara ngosi na RF fiber optical module wee gbanwee gaa na akara laser, mgbe ahụ, a na-ebufe akara ngosi laser na MU, akara ngosi laser sitere na RU na-atụgharị gaa na mgbaàmà RF site na transceiver RF.Mgbe ahụ, a na-ebuli akara ngosi RF ka ọ bụrụ akara ike ọzọ enyere na BTS.
Emebere RF Repeater iji kwalite mkpuchi netwọkụ ekwentị ma mejupụta ntụpọ kpuru ìsì.Isi ọrụ nke onye na-emegharị ihe bụ ịnata akara ngosi dị ala site na Base Station (BS) site na nnyefe ugboro redio (RF) site na antenna onye nyere ya, usoro, gbasaa na zipu mgbaàmà na Mobile Station (MS) na mpaghara mkpuchi mkpuchi site na ọrụ ya. antenna.
