5 Best Practices for Smartphone Support
The technology is designed to operate with WiFi enabled cellphones to enable them to both make and receive calls, via VoIP over WiFi and an IP PBX when within an organisation's office and via a cellular network elsewhere. Calls to a user's fixed line office number will be routed via WiFi to the cellphone if the phone is on the premises and via the cellular network if it is not. Eventually in-progress calls will be able to be handed over seamlessly from WiFi to cellular and vice versa as the user moves off the premise and out of range of the WiFi network or enters the premises. Telarus managing director, Jules Rumsey, told iTWire: "Aruba has a roadmap to full fixed mobile convergence. The next stage is the most critical: the enterprise integration. There is some software that goes into the Aruba controller and some integration with the phone system and a plug-in that goes on the handset. "When the devices reaches the edge of the network to the point that call quality starts to suffer it will be able to hand off to the cellular network. The cellphone and the phone system signal to each other through the Aruba controller. When the WiFi signal falls off the mobile initiates a cellular call and then the WiFi call is dropped. That is going live at the end of this calendar year." He added: "Aruba have been working closely with Avaya on the phone system side and with Nokia on the handset side." Handoff from cellular to WiFi is somewhat further down the track. "The next stage Aruba is working on, probably about early 2008, is the carrier integration side. They are working with the carriers to tighten up the signalling between the WiFi devices and the carrier network so that they can do a really good job of seamless integration," Rumsey said. At present a number of Nokia handsets support the Aruba plug-in. "But you can expect them to roll this out across other models once they get through the development phase," Rumsey said. Critical to an FMC service operating reliably are a WiFi network and corporate LAN with the necessary coverage, capacity and service quality. To help customers implement these, Telarus has released a wireless network design and audit service, which, it claims is being particularly well received by its channel partners. "Many systems integrators and value-added resellers do not have these specialist skills so we are engaging with our channel partners to support them in successfully enabling next generation services for their clients," Rumsey said.{moscomment} |
