Hvordan utfasingen av 2G og 3G vil påvirke IoT-kommunikasjon

IoT-kommunikasjon er et område i konstant utvikling, og den nært forestående utfasingen av 2G- og 3G-nettverkene kaster en skygge over økosystemet for IoT (tingenes internett).

I takt med den raske utrullingen av 4G- og 5G-teknologier, nærmer pensjoneringen av eldre nettverk seg med stormskritt. I denne bloggartikkelen utforsker vi implikasjonene utfasingen av 2G og 3G vil ha for IoT-kommunikasjon, og gir deg tips til hvordan du kan forberede deg på dette teknologiske skiftet.

Forberedelser til utfasingen: et globalt skifte

Det er en stund siden 4G gjorde sitt inntog, og siden 4G- og 5G-nettverk nå er blitt utbredt over hele verden, er utfasingen av 2G og 3G allerede i gang i flere land.

Tidspunktet for nedstenging av nettverkene varierer fra region til region, og er drevet av teleselskapenes overgang til nyere, mer avanserte teknologier som 4G og 5G.

Siden 2G-nettverkene har vært i drift i mer enn tretti år, vil overgangen få store konsekvenser for IoT-utstyr som bruker disse teknologiene. Mange IoT-løsninger med livssyklus på ti år eller mer er fortsatt avhengige av 2G, noe som vil kreve strategisk handling for å sikre fortsatt drift etter utfasingen av 2G- og 3G nettverkene.

Et geografisk lappeteppe av utfasingsdatoer

Takten på utfasingen av 2G/3G er svært varierende rundt om i verden, med mange ulike utfasingsdatoer avhengig av markedenes egenskaper. I henhold til opplysninger fra GSMA Intelligence vil mer enn 55 2G- og 3G-nettverk stenges ned mellom 2021 og 2025. Interessant nok vil ikke 2G og 3G nødvendigvis stenges samtidig, og i noen markeder forventes det at 2G-tjenestene vil videreføres for spesielle behov, som f.eks. mobilbetaling i Afrika og nødanrop i biler i andre regioner.

Utfasing av 3G i Europa: en planlagt overgang

Utfasingen av 3G startet for flere år siden, og flere land er allerede i mål med omstillingen. Europa skiller seg ut ved at det har vært flere utfasinger av 3G enn 2G, og det er 19 operatører i 14 land som planlegger å slå av 3G-nettverk innen 2025. Imidlertid er det langt fra like mange nedstenginger av 2G-nettverk: Åtte operatører i åtte land planlegger utfasing innenfor samme tidsramme.

Innvirkning på IoT-utstyr: navigering i et komplekst landskap

Utfasingen av 2G- og 3G-nettverk kan være en utfordring for IoT-utstyr, ettersom mange enheter fortsatt kun støtter 2G/3G og bare er halvveis i sin forventede levetid. Utskifting av utstyr vil føre til økte kostnader og ha negativ innvirkning på forretningscaser på IoT-området, basert på en forutsetning om lang levetid på single-mode maskinvare.

Begrense konsekvenser for kunder og forberedelser for migrering

Det er avgjørende å handle så tidlig som mulig for å begrense konsekvenser for kunder etter hvert som 3G i stadig større grad blir en nisjeteknologi. Et eksempel er et kommunalt kollektivsystem i San Francisco, som kan bli nødt til å stenge ned på grunn av sin avhengighet av 2G etter at nettverket slås av. Dette viser at det er behov for nøye planlegging og en trinnvis omlegging fra 2G og 3G.

Omlegging til framtidsrettet kommunikasjon

En strategisk gjennomgang av installerte enheter er første skritt for IoT-bedrifter når det gjelder å forstå hvilke enheter som må oppgraderes. Det er viktig å velge framtidsrettet maskinvare og vurdere alternative teknologier som LTE-M (Long Term Evolution for Machines) og NB-IoT (tingenes internett på smalbånd). For å unngå en såkalt "midtlivskrise" må man se nøye på teknologiens levetid og hvor lenge enhetene kan utplasseres.

Etter utfasingen: innføring av 4G og 5G

Utviklingen av alternative teknologier som 4G og 5G, i tillegg til spesielle IoT- løsninger som NB-IoT og LTE-M, har gjort det mulig å ta steget videre fra 2G- og 3G-nettverk. Disse teknologiene gir mulighet for globale løsninger med utvidede funksjoner, åpner for nye muligheter innen landbruk, vann- og energiverk, logistikk og andre næringer.

Com4s forpliktelse til og støtte for IoT

Vi i Com4 har omfattende global erfaring på dette området, og står klare til å støtte våre kunder gjennom dette teknologiske skiftet. Samarbeid med kunder og partnere, strategisk planlegging og evaluering av muligheter for modernisering vil sikre en god overgang til 4G og 5G, som kan åpne for nye funksjoner bygget på IoT-baserte nettverk.


Under følger en oppdatert liste over utfasinger som er annonsert eller allerede har skjedd. Selv om vi prøver å holde denne listen så korrekt som mulig, gjør vi oppmerksom på at vi ikke har full oversikt over alle oppdateringer på alle nettverk verden rundt. Nettverk som ikke står i denne tabellen har kanskje ikke gått ut offentlig med sine planer for nedstenging av 2G- eller 3G-nettverk. Det er viktig å merke seg at nettverkene kun er pålagt å gi tre måneders varsel til kundene sine om nedlegging av nettverkstjenester.
