==PCS network in the United States==
In the United States, [[Sprint Corporation|Sprint PCS]] was the first company to build and operate a PCS network, launching service in November 1995 under the ''Sprint Spectrum'' brand in the [[Baltimore-Washington metropolitan area]].  Sprint originally built the network using [[GSM]] radio interface equipment.  Sprint PCS later selected [[CDMA2000|CDMA]] as the radio interface for its nationwide network, and built a parallel CDMA network in the Baltimore-Washington area, launching service in 1997.  Sprint operated the two networks in parallel until finishing a migration of its area customers to the CDMA network.

After completing the customer migration, Sprint PCS sold{{when|date=August 2022}} the GSM radio interface network equipment to Omnipoint Communications in January 2000.{{Sfn|Cambridge Telecom Report|2000}}  
Omnipoint was later purchased by VoiceStream Wireless{{when|date=August 2022}} which subsequently became [[T-Mobile US]].

In August 2022, T-Mobile US announced [[cellular dead zone|dead-zone]] cell phone coverage across the US using "midband" (1900 MHz) PCS spectrum<ref name="tmus-midband">{{cite web |url=https://www.lightreading.com/5g/t-mobile-is-winning-race-to-100mhz-for-midband-5g/a/d-id/773516 |title=T-Mobile is winning the race to 100MHz for midband 5G |publisher=Light Reading |date=2021-11-15 |access-date=2022-08-25 |archive-date=2 June 2022 |archive-url=https://web.archive.org/web/20220602044824/https://www.lightreading.com/5g/t-mobile-is-winning-race-to-100mhz-for-midband-5g/a/d-id/773516 |url-status=live }}</ref> and [[Starlink]] Gen2 satellite<!-- in [[low-Earth orbit]] --> cell coverage, to begin testing in 2023.
