What is it |
What is changing |
GSM / GPRS / 3G |
Mobile network technologies; GSM for voice traffic and GPRS and 3G for data connectivity. |
The networks themselves aren’t converging but the devices are. Single device solutions are key to many of the latest handset ranges. |
Fixed and mobile convergence |
Uses a local GSM connection to route mobile calls through your PBX to achieve cost efficiencies. |
Many fixed and mobile network operators have invested in local GSM licences but we’ve only seen limited product solutions so far. |
Mobile private links |
Routes office to mobile calls directly to the mobile networks to reduce costs. |
Also virtual private mobile networks allow you to select the right mobile network to avoid mobile interconnect charges. |
WiFi / WiMax |
Removes the wires altogether. WiFi can be used privately, for corporate network access in the office, or publicly from a hot-spot. |
WiMax is a larger scale version of WiFi. Any users within a WiMax district can connect wirelessly. In the future we could be seeing offices in WiMax areas needing no cabling at all. |
