Examples of RAN types are:
- GSM
- GERAN: essentially the same as GRAN but specifying the inclusion of EDGE packet radio services
- UMTS
- latency
It is also possible for a single handset/phone to be simultaneously connected to multiple RANs. Handsets capable of this are sometimes called dual-mode handsets. For instance it is common for handsets to support both GSM and UMTS (a.k.a. "3G") RATs. Such devices seamlessly transfer an ongoing call between different radio access networks without the user noticing any disruption in service.
RAN in the United States
According to research company New Street, mobile providers
Verizon primarily uses South Korean provider Samsung. Nokia is the minority vendor for all major US wireless providers. According to EJL Wireless Research, Verizon is also using Ericsson.[2]
