2. Mobile VoIP - Technologies
Unlicensed Mobile Access|UMA — the Unlicensed Mobile Access Generic Access Network allows VoIP to run over the GSM cellular backbone.

3. LTE (telecommunication) - Voice calls
The lack of software support in initial LTE devices as well as core network devices however led to a number of carriers promoting VoLGA (Voice over LTE Generic Access) as an interim solution.[ VoLGA whitepaper] The idea was to use the same principles as Generic Access Network|GAN (Generic Access Network, also known as UMA or Unlicensed Mobile Access), which defines the protocols through which a mobile handset can perform voice calls over a customer's private Internet connection, usually over wireless LAN

4. Generic Access Network
'Generic Access Network' or 'GAN' is a telecommunication system that extends mobile voice, data and IP Multimedia Subsystem/Session Initiation Protocol (IMS/SIP) applications over IP networks. 'Unlicensed Mobile Access' or 'UMA', is the commercial name used by mobile carriers for external IP access into their core networks.

5. 802.21 - Similar technologies
Generic Access Network|Unlicensed Mobile Access (UMA) technology is basically a mobile-centric version of UMA is said to provide roaming and handover between GSM, UMTS, Bluetooth and IEEE | networks. For more information on UMA you can go to

6. 802.21 - Similar technologies
Since June , UMA is a part of the ETSI 3GPP standardization process under the GAN (Generic Access Network) Group.

7. IP Multimedia Subsystem
Alternative and overlapping technologies for access and provisioning of services across wired and wireless networks include combinations of Generic Access Network, Softswitch|soft switches and naked SIP.

8. Triple play (telecommunications) - Quadruple play
Typical Generic Access Network services of this kind, such as Rogers Home Calling Zone, allow the caller to enter and leave the range of their home Wi-Fi network, and only pay GSM rates for the time they spend outside the range

9. Mobile data offloading - Cellular and Wi-Fi network interworking
3GPP based Enhanced Generic Access Network (EGAN)[ 3GPP TR ] architecture applies tight coupling as it specifies rerouting of cellular network signaling through Wi-Fi access networks

10. Windows Mobile - Windows Mobile 6
320x320 and 800x480 (WVGA) screen resolution support (The S01SH or Em One by Sharp was the first and only device to have a 800x480 screen on WM5), Improved Terminal Services|Remote Desktop access (Available for only certain Pocket PCs), Customer Feedback option, Smartfilter for searching within programs and Generic Access Network|Unlicensed Mobile Access (UMA) support for select operators

11. BlackBerry Curve 8530 - BlackBerry Curve 9350/9360/9370
All the phones include Near field communication|NFC, Generic Access Network|Wi-Fi Calling and FM radio with the OS 7.1 upgrade. The 9370 has more eMMC memory than its siblings at 1GB as compared to 512 MB.

12. Handover - Vertical handover
The 3GPP Generic access network|UMA/GAN standard enables GSM/UMTS handoff to Wi-Fi and vice-versa.

13. Fixed-mobile convergence - Carrier FMC compared
Carrier FMC normally uses one of two technologies to implement session continuity, Voice call continuity|VCC or unlicensed mobile access, also known as Generic Access Network or UMA. UMA is an older technology, which transports GSM packets through the IP network; the handset uses the same GSM signaling stack for Wi-Fi calls as for cellular. With the predicted conversion of the carrier networks to all-IP, UMA has been superseded by VCC, which uses SIP signaling.

14. List of Nokia products - Nokia 6xxx – Classic Business series (1997–2010)
Nokia 6136 UMA is the first mobile phone to include Generic Access Network|Unlicenced Mobile Access. Nokia 6131 NFC is the first mobile phone to include Near Field Communication.

15. Evolved Packet System - Voice calls
The lack of software support in initial LTE devices as well as core network devices however led to a number of carriers promoting VoLGA (Voice over LTE Generic Access) as an interim solution.[ VoLGA whitepaper] The idea was to use the same principles as Generic Access Network|GAN (Generic Access Network, also known as UMA or Unlicensed Mobile Access), which defines the protocols through which a mobile handset can perform voice calls over a customer's private Internet connection, usually over wireless LAN

16. In iOS 8, Apple integrated Generic Access Network|Wi-Fi calling

17. Wi-Fi Calling
'Generic Access Network' or 'GAN' is a telecommunication system that extends mobile voice, data and multimedia (IP Multimedia Subsystem|IMS/Session Initiation Protocol|SIP) applications over IP networks

18. Media independent handover - Related Standards
Another standard that can be used for handover from one wireless technology to another is UMA, Unlicensed Mobile Access, which provides handover between WiFi and GSM/GPRS/UMTS. It was originally developed by an independent industry consortium and was incorporated into the 3GPP standards in 2005 under the name GAN (Generic Access Network).

19. Windows Mobile 2003 SE - Windows Mobile 6
