Wi-Fi Alliance Begins Certifying Devices for Voice Over Wi-Fi

The Wi-Fi Alliance is launching a new certification program for voice-capable Wi-Fi devices in home and small office environments. The first wave of devices has passed certification. The Wi-Fi Alliance estimates that shipments of Wi-Fi/cellular converged phones will number between 250 and 350 million units in 2011.

The new Wi-Fi CERTIFIED Voice-Personal program extends beyond interoperability testing to test the performance of products and help ensure that they deliver good voice quality over the Wi-Fi link.

Voice over Wi-Fi is typically used within mixed voice and data environments, in which multiple data streams compete for the available network resources. Products that successfully achieve Voice-Personal certification prioritize voice communication over data, audio, or video traffic, and also have met strict performance levels for key metrics that ensure a quality experience in voice applications: packet loss, latency and jitter.

Products Wi-Fi CERTIFIED Voice-Personal have also passed tests for core interoperability (802.11a/b/g or 802.11n draft 2.0) and Wi-Fi Protected Access 2 (WPA2) for the strong security protections, as well as Wi-Fi Multimedia (WMM) for quality of service and WMM Power Save (access points only). Users should look for both access points and client devices that are Wi-Fi CERTIFIED Voice-Personal to ensure optimal voice quality when making calls over a Wi-Fi network.

The following are among some of the first devices to become Wi-Fi CERTIFIED Voice-Personal:

  • Broadcom BCM94704AGR High Performance Dual-Band (2.4/5 GHz) Router Reference Design

  • Cisco Systems Aironet 1250 Series Access Point (AIR-AP1252AG )

  • Cisco Systems Aironet 1200 Series Access Point (AIR-AP1231G with AIR- RM21A)

  • DSP Group Expeditor Reference Design (with XpandR 1.01 software)

  • Intel Wireless WiFi Link 4965AGN

  • Intel PRO/Wireless 3945ABG Network Connection

  • Meru Networks AP200

  • Redpine Signals Lite-Fi TGn SDIO

A list of all products Wi-Fi CERTIFIED Voice-Personal, as well as a free white paper which describes the program in detail, is available online.

RadiSys Adds Speech Capabilities to Convedia Media Server

RadiSys' Convedia media server family now supports automatic speech recognition (ASR), or converting human speech to computer data, and text-to-speech (TTS) capabilities in multiple languages for IP contact center application developers and service providers. The solution integrates standards-based Media Resource Control Protocol (MRCP) .

With the introduction of ASR and TTS support, RadiSys said its media servers can now be used in conjunction with speech servers to deliver a more cost-effective and scalable deployment model. Previously, Convedia media servers could process Session Initiation Protocol (SIP) commands and VoiceXML scripts to apply media processing against Real Time Protocol (RTP) media streams in a VoIP or IMS architecture. With the new capabilities, an ASR or TTS request written in the VoiceXML script is forwarded using a standards-based Media Resource Control Protocol (MRCP) interface to an adjunct speech server. The net result is that speech servers now can focus exclusively on ASR and TTS processing, while all other media processing is done within the Convedia media server.

J:COM Deploys DOCSIS 3.0 with Cisco

Japan's Jupiter Telecommunications (J:COM) has begun deployment of the Cisco DPC3000 DOCSIS 3.0 Channel Bonded Cable Modem for use in its J:COM NET Ultra 160M Course broadband service, which offers download speeds of up to 160 Mbps.

The Cisco DPC3000, which has received CableLabs DOCSIS 3.0 certification, uses four bonded channels for both the downstream and upstream data, enabling downstream data rates in excess of 160 Mbps and upstream data rates up to 120 Mbps. It is designed to be backward-compatible for use as a single-channel cable modem with DOCSIS 2.0, 1.1 or 1.0 networks.

In addition to DOCSIS 3.0-compliant cable modems, the Cisco downstream channel-bonding solution features the Cisco uBR10012 cable modem termination systems (CMTS) and Cisco xDQA-24 edge quadrature amplitude modulators (QAMs).
  • In April 2008, Motorola announced that Jupiter Telecommunications (J:COM), Japan's largest multiple system operator (MSO), had selected Motorola's channel bonding technology to deploy the company's first DOCSIS 3.0-based Cable Modem Termination System (CMTS) and cable modems. Specifically, Motorola said the deployment uses its DOCSIS 3.0-based BSR 64000 CMTS/Edge Router and SURFboard SB6120 cable modems. Financial terms were not disclosed. Motorola said its solution is capable of delivering up to 160Mbps throughput to residential and commercial customers.

Court of Appeals Upholds FCC Video Franchise Rules.

The U.S. Court of Appeals for the 6th Circuit ruled unanimously to support the FCC's local franchising authority rules for new entrants in video services.

"Over the last ten years, cable rates have more than doubled. Consumers need greater choice and more competition to help address the soaring price of cable television. This ruling helps ensure that new competitors to cable are not subjected to unreasonable delays, build-out requirements and fees when trying to compete with the incumbent cable operators," stated FCC Chairman Kevin Martin.
  • In December 2006, The FCC voted 3-to-2 to approve new rules that prohibit local franchising authorities from unreasonably refusing to award competitive franchises for the provision of cable services. The vote was seen as a victory for A&T, Verizon and other telephone providers seeking to enter the market for video services.

    The majority of FCC commissioners concluded that the current franchising process required by local municipalities constitutes an unreasonable barrier to entry that impedes the achievement of the interrelated federal goals of enhanced cable competition and accelerated broadband deployment.

    The new rules prohibit towns or cities from engaging new market entrants in drawn-out local negotiations with no time limits; unreasonable build-out requirements; unreasonable requests for "in-kind" payments that attempt to subvert the five percent cap on franchise fees; and unreasonable demands with respect to public, educational and government access.

Comcast Completes 100 Gigabit Ethernet (GE) Router Test with Cisco

Comcast has completed a 100 Gigabit Ethernet (GE) technology test over its existing backbone infrastructure between Philadelphia and McLean, VA using the industry's first 100GE router interface developed for the Cisco CRS-1 routing system.

The Cisco CRS-1 100GE interface uses Comcast's existing optical infrastructure to enable transmission of 100GE over DWDM fiber optic networks. Cisco said the use of 100 Gigabit Ethernet router interfaces enables greater bandwidth per wavelength by a factor of 10 over the initial deployed capability. It also creates efficiencies by simplifying routing and operations through the use of statistically multiplexed 100GE links, in comparison to carrying the same amount of traffic split over more commonly used 10GE links.

Cisco also noted that the implementation tested by Comcast is consistent with the emerging IEEE 802.3ba 100GE standard and validates the use of 100GE and IPoDWDM technologies over Comcast's own production network, which was the first, and is currently the world's largest 40G IPoDWDM network.
  • In March 2008, Comcast conducted a test of Nortel's 100 Gbps line rate optical transmission solution at the 71st meeting of the Internet Engineering Task Force (IETF) conference, which was held in Philadelphia. The 100G solution ran over Comcast's existing fiber network. The test network was comprised of Comcast's existing Common Photonic Layer DWDM solution with 50GHz enhanced Reconfigurable Optical Add/Drop Multiplexer (eROADM) and photonic components, augmented with prototype 100G interfaces installed in Nortel's Optical Multiservice Edge 6500. The 100G cards utilize Nortel's 40G/100G Adaptive Optical Engine, with integrated dispersion compensation and dual-polarization Quadrature Phase Shift Keying (QPSK) modulation, the same technology used in Nortel's present 40G solution. The 100G trial runs from Philadelphia to McLean (Virginia), traversing Comcast's metro and long-haul fibers. The companies said Comcast's network trial was the first time real traffic is run over a 100G wavelength on its existing network. The network also carried live 10G and 40G links. The trial ran in parallel over the same optical infrastructure that supports a combination of high definition or HD video, Internet and voice traffic on Comcast's 40G national backbone network.

New Forum Established to Address Network Security -- ICASI

A new Industry Consortium for Advancement of Security on the Internet (ICASI) has been founded by Cisco, IBM, Intel, Juniper Networks and Microsoft, with the aim of enhancing global IT security by proactively driving excellence and innovation in security response.

ICASI's mission is to provide a forum for global companies committed to proactively addressing complex, multi-product security threats and to better protecting enterprises, governments and citizens, as well as the critical IT infrastructures that support them.

The founding companies said their action is necessitated by the increasing sophistication of Internet attacks and the integration of applications, now common in IT environments, that pose real challenges for IT vendors. Online attacks occur more frequently and in more rapid succession, while often spanning international boundaries.

ICASI does not seek to respond to every product security issue that emerges, but rather the consortium is designed to respond to and ideally reduce the potential customer impact of global, multi-vendor cyber threats. The organization is organized around four guiding principles.

  • Customer security - Through ICASI's collaboration and leadership, IT vendors will be better able to identify and resolve multi-vendor security threats quickly, thereby helping to reduce the security threat impact and improve customer security.

  • Agility and effectiveness - ICASI is committed to improving the efficiency and effectiveness of multi-vendor threat resolution and security response practices.

  • Collaboration and trust - ICASI creates a unique environment where information, necessary to quickly solve security-related threats, can be shared, as appropriate.

  • Leadership and innovation - ICASI includes leading IT companies from around the world and leverages their expertise to innovate security response excellence, which it shares with the industry.
