Wireless kutaurirana muhupenyu hwezuva nezuva
Wave:● Mhedzisiro yekukurukurirana ndeyekufambiswa kwemashoko, kunyanya nenzira yemafungu. ● Masaisai akakamurwa kuita masaisai emagetsi, masaisai emagetsi, masaisai ematter uye masaisai egiravhiti (quantum communication). ● Mhuka nezvinomera zvakadzidza kushandisa masaisai eruzha, infrared uye chiedza chinooneka kuburikidza nekuongorora kwekushanduka-shanduka.
electromagnetic waves:
Parizvino, inonyanya kushandiswa electromagnetic wave ndeye electromagnetic wave, iyo inogona kukamurwa kuita zvikamu zvakati wandei zvakajairika:
●Radhiyo (R) (3Hz~300MHz) (TV, redhiyo, nezvimwewo)
●Microwave (IR) (300MHz~300GHz) (radar, zvichingodaro)
●Infrared (300GHz~400THz)
● Chiedza chinooneka (400THz~790THz)
●UV
● X-ray
● gamma mwaranzi
Zuva Nezuva Application:
Mabhendi akapatsanurwa uye anoshandiswa kune zvinangwa zvakasiyana, senge AM, FM, nhepfenyuro yeTV, satellite kutaurirana, nezvimwe, unogona kutarisa kune magwaro epamutemo edzimwe nyika.GSM, 3G, uye 4G ese ma microwaves.
Satellite zvakare microwave kutaurirana.Iyo yakanyanya kufanirwa frequency yekutaurirana setiraiti ndeye 1-10GHz frequency bhendi, kureva, iyo microwave frequency band. Kuti usangane nezvido zvakawanda uye zvakawanda, mabhendi matsva akadzidziswa uye akaiswa, akadai se12GHz, 14GHz, 20GHz uye 30GHz.Huhutong is satellite TV, inoshandirwa neZhongxing 9 satellite.Mune mamwe mazwi, kurongedza kweiyo live nhepfenyuro system ine simba chaizvo, ingoenda kune yepamutemo webhusaiti kuti uione.Nharembozha dzesatellite (dzekufamba uye ngarava) dzatove saizi ye smartphone.Bluetooth uye wifi ma microwaves.Air conditioners, mafeni, uye ruvara TV remote controls infrared.NFC iredhiyo (Near Field Communication ipfupi-renji, yakakwirira-frequency radio tekinoroji inoshanda pa13.56MHz pachinhambwe che20cm).RFID tags (yakaderera frequency tags (125 kana 134.2 kHz), yakakwirira frequency tag (13.56 MHz), UHF tags (868~956 MHz) uye microwave tag (2.45 GHz)
