FortiOS Carrier

Radio Access Technology (RAT) type

The RAT type represents the radio technology used by the mobile device. This can be useful in determining what services or content can be sent to a specific mobile device. FortiOS Carrier supports:

  • UMTS Terrestrial Radio Access Network (UTRAN), commonly referred to as 3G, routes many types of traffic including IP traffic. This is one of the faster types.
  • GSM EDGE Radio Access Network (GERAN) is a key part of the GSM network which routes both phone calls and data.
  • Wireless LAN (WLAN) is used but not as widely as the other types. It is possible for the mobile device to move from one WLAN to another such as from an internal WLAN to a commercial hot spot.
  • Generic Access Network (GAN) can also be called unlicensed mobile access (UMA). It routes voice, data, and SIP over IP networks. GAN is commonly used for mobile devices that have a dual-mode and can hand-off between GSM and WLANs.
  • High Speed Packet Access (HSPA) includes two other protocols High Speed Downlink and Uplink Packet Access protocols (HSDPA and HSUPA respectively). It improves on the older WCDMA protocols by better using the radio bandwidth between the mobile device and the radio tower. This results in an increased data transfer rate for the user.
