Wi-Fi VoIP with Cicero

  1. 1. Issue 135 BluePrint Wi-Fi Volume 1, Number 1 Wi-Fi VoIP with Cicero 18 May 2005 Matt Lewis No sooner had voice over IP established itself at Commentary Wi-Fi VoIP with Cicero 1 the beachhead of the telecoms industry than wireless VoIP came a knocking at the same door - and until WiMAX or any other wide-area broadband wireless technology gains market Top Stories traction, wireless VoIP will typically be Motorola formalizes industry alliance for its 2 synonymous with voice over Wi-Fi. In the past dual-mode platform few months alone, there have been a number of announcements, by significant Vonage tests routers for mobile VoIP 3 industry players, promoting solutions to make pushing voice packets over Wi-Fi Hopes rise for UltraWideBand harmony 3 networks a commercial reality. At 3GSM in Cannes, Skype announced that its Nintendo and Microsoft beef up wireless 4 VoIP client will be leveraged on Wi-Fi enabled handsets from both Motorola and i- gaming mate; Philips has announced a cellular handset reference platform with integrated Security group warns of VPN vulnerabilities 4 Wi-Fi and support for the fixed-mobile UMA standard; and rumours surfaced this Fiberlink adds Skype to remote access 4 week that Vonage is on the verge of adding a Wi-Fi voice element to its residential portfolio VoIP service. Nokia introduces enterprise Wi-Fi platform 5 On one hand, implementing voice over Wi-Fi can be a fairly straight forward process. Whether the device is a Wi-Fi notebook, PDA or mobile phone, it simply requires the installation of a softphone client (such Xten’s softphone or the Skype Hotspots client) and an account with a VoIP service provider. In addition to a network Nextel moves into Wi-Fi with Boingo and 5 identifier, many VoIP providers will also provide each customer with a PSTN Wayport number so both incoming and outgoing PSTN calls can be made and received. Public safety hotzone planned for Oregon 6 However, without a more integrated approach to marrying client and network UK’s community wireless networks mapped 6 infrastructure technologies, it is difficult to manage issues which arise with wireless Boingo and Fatport in new roaming deals 6 voice transmissions: these include quality of service as signal strength degrades, as well as hand-off between access points as the caller moves throughout the coverage area. Integrating with cellular features on both the client and the network side also helps service providers to better monitize on offering wireless VoIP. Vendors Colubris-Avaya alliance points to anti-Cisco 7 With this room for innovation, there are a number of smaller companies attempting ecosystem to secure a seat on the wireless VoIP bandwagon. Typically, these companies have Trapeze adds Enterasys to partner list 7 developed end-to-end solutions which are offered through service providers and consist of both a network infrastructure and a client application element. Some of these companies, like Kineto, have a standards-based solution; in Kineto’s case, it is the UMA standard. Others, like Cicero Networks, have SIP and RTP compliant Standards and Regulation implementations which, in Cicero’s case, have been extended to add functionality. Moves towards open standard for WLAN 7 security policy Based in Ireland, Cicero Networks is a private start-up founded in 2002 and the company released version 2.0 of its Wi-Fi VoIP solution in March this year. Its Microsoft XP supports WPA2 security 8 target markets are fixed-line operators, alternative service providers and large enterprises looking to leverage the economic benefits of converged cellular/Wi-Fi devices. Semiconductors These economic benefits are not insignificant. In an example drawn out by Cicero WLAN chipmaker closes its doors 8 for its native Irish market, the cost of routing a three minute outbound call from a cellular/Wi-Fi device over O2’s mobile network and Eircom’s fixed network is five times more expensive than if the same call was simply routed over Wi-Fi and then Metrics onto the fixed network. ABI forecasts over 100m dual-mode 9 Ross Brennan, Cicero co-founder and CEO, acknowledges that it is the enterprise handsets by 2010 which represents Cicero’s primary audience, either as direct customers or, more typically, through a telco provider which has incorporated the Cicero infrastructure into its network. Last month, Irish Telco, Talktelecom, became the first European Deals wireline operator to offer VoWi-Fi services, deploying the Cicero solution to offer Proxim warns of bankruptcy risk 9 wireless VoIP to its corporate customers. Wayport acquires NetPoint in Denmark 10 Other customers on Cicero’s radar are cable operators and MNVOs, but Brennan believes that the cellular operators are still resistant to the idea of integrating their cellular networks with other wireless technologies. Events Although it is IP-bearer agnostic, the Cicero solution is very much a Wi-Fi voice Conferences 10 technology and it is optimised for the delivery of voice packets over a local wireless LAN onto the PSTN and visa versa. Two key optimisations are quality of service control and access point handoff. By monitoring the strength of the Wi-Fi signal and the bandwidth available within the network, the Cicero solution is able to manage QoS by dynamically adjusting the level of voice compression, using, for 1 Copyright © 2005 ARCchart ltd.

The Cicero softphone is another.

By by one of Cicero’s vendor partners, such as comparison, UMA sits at a deeper level of Colubris, the hand-off will be the handset telephony stack and must “imperceptible” to the caller. therefore be implemented by the handset vendor. This will limit the installed based of UMA devices in the market (there are still none which are commercially available) while the Cicero client can, in theory, work on any existing Wi-Fi enabled Windows Mobile and Symbian device – although this will depend on the processing capability of the device since voice compression must takes place at the software level.
