Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Skupni vmesnik (CI) - 3. del: Plast krmiljenja dostopa do prenosnega medija (MAC)
Ta dokument je eden od delov specifikacije skupnega vmesnika (CI) za digitalne izboljšane brezvrvične telekomunikacije (DECT).
Ta dokument določa ureditve fizičnega kanala. Fizični kanali digitalnih izboljšanih brezvrvičnih telekomunikacij so poti radijske komunikacije med dvema radijskima končnima točkama. Radijska končna točka je del fiksne strukture, tj. fiksni del (FP) v zasebni lasti – običajno bazna postaja, ali prenosni del (PP) – običajno slušalka. Dodelitev enega ali več določenih fizičnih kanalov klicu je opravilo, ki ga izvajajo višje plasti.
Fizična plast (PHL) je povezana s plastjo krmiljenja dostopa do prenosnega medija (MAC) in entiteto upravljanja nižjih plasti (LLME). Na drugi strani fizične plasti je medij za radijski prenos, ki je namenjen obsežni skupni uporabi več uporabnikov digitalnih izboljšanih brezvrvičnih telekomunikacij in različnim radijskim storitvam. Opravila fizične plasti je mogoče združiti v pet kategorij:
a) modulacija in demodulacija radijskih nosilcev z bitnim pretokom določene stopnje za ustvarjanje radiofrekvenčnega kanala;
b) pridobivanje ter vzdrževanje bitne in režne sinhronizacije med oddajniki in prejemniki;
c) oddajanje ali prejemanje določenega števila bitov ob zahtevanem času in na določeni frekvenci;
d) dodajanje in odstranjevanje polja sinhronizacije in polja Z, ki se uporablja za zaznavanje trka v zadnji del vozila;
e) opazovanje radijskega okolja za sporočanje moči signala.
Ta dokument vključuje novo generacijo digitalnih izboljšanih brezvrvičnih telekomunikacij, nadaljnji razvoj standarda za digitalne izboljšane brezvrvične telekomunikacije, ki uvaja širokopasovni govor, izpopolnjene podatkovne storitve, nove tipe rež in druge tehnične izpopolnitve.
