Strix Scales Wireless Mesh Networks

Strix Systems introduced a new, third-generation Outdoor Wireless System and a new High Performance Modular Architecture for large-scale mesh networks.



The new OWS 2400-30 offers increased user density, provides enhanced transmit power and receive sensitivity, a 30% smaller form factor and lower cost per radio compared to earlier products. The new design doubles from 64 to 128 the number of WLAN associations permitted per radio, allowing up to 768 concurrent users per node. Modularity lets the OWS 2400-30 scale to up to six radios as needed (802.11a/b/g/j, 802.16d/e, 2.4 GHz, 4.9GHz and 5 GHz in any access and backhaul configuration.



The new High Performance Modular Architecture offers Scalable Mesh Fast Re-route (SMFR) capabilities for distributed localized node intelligence, network topology-independent fast re-route, instant roaming, zero throughput loss, and zero latency over multiple hops. Strix said it is able to deliver cero throughput loss and zero latency for over 10 hops, enabling real-time applications and lowering OPEX costs for the number of wired connections needed for a given area.



When networks are turned up, every node automatically scans to locate all other network nodes and selects the best path to the wired node based on round-trip delay (RTD), signal-to-noise ratio (SNR), and other criteria. The nodes continue to scan and evaluate the best path and alternate paths to the wired node, automatically self-healing to the next-best path within milliseconds if the criteria of the best path drops below the set threshold or the path is blocked.



Strix also noted that in mobile applications, its Scalable Mesh Fast Re-route can deliver hand-offs for trains traveling at up to 200 mph.



SMFR also supports real-time node-state status indication, real-time backhaul path analysis, a congestion-avoidance algorithm, and an optimal channel re-use algorithm.

Which
Mesh Architecture is Best for Delivering VoIP?


by
Cyrus Irani
For
wireless data networks, voice is a "killer app." This article
will first look at the four key mesh network performance requirements for
real time applications; the three mesh architectural options when
deploying wireless voice over IP (wVoIP) over a WiFi mesh network; how a
multi-radio, multi-RF architecture positively impacts the capital cost to
deploy; and the operating expenses involved to properly operate such
networks.

DiVitas Develops Enterprise FMC Platform

DiVitas Networks, a start-up based in Mountain View, California, is developing an enterprise-class fixed-mobile-convergence (FMC) platform that would enable seamless roaming between Wi-Fi and cellular networks. The platform is being designed to work with in any corporate WLAN environment, with any PBX, and over any type of fixed, mobile, or wireless network. A light, client application would run on the dual-mode handset.



DiVitas said thekey mission for its forthcoming platform is to provide the cost advantages of seamlessly bridging cellular calls over to lower cost WLANs while enabling enterprises to retain control of this process. This would include the ability to monitor media quality in order to specify when and how handoffs should occur, and the ability to implement advanced security. Security capabilities include application-layer authentication, authorization and access control, session-layer end-to-end encryption, packet filtering and bandwidth policing, network-layer STUN, NAT/Firewall Traversal and automatic pre-authentication.



The platform is currently in beta testing. Full product details have not yet been disclosed. DiVitas has conducted interoperability testing with Trapeze Networks' WLAN Mobility System to enable enterprise campus mobility with fixed mobile convergence. DiVitas has also entered into a relationship with G-Tek Electronics Group, which supplies a dual-mode SIP Wi-Fi handset that integrates GSM/GPRS and Wi-Fi modules.



DiVitas was founded by president and CEO Vivek Khuller and CTO Venkat Kalkunte. Khuller was previously a venture partner at Clearstone Venture Partners, entrepreneur in residence at Matrix Partners, and an executive at Sycamore Networks and Verizon. Kalkunte formerly worked at Cisco, and was founding engineer of Transmedia Communications, which Cisco purchased in 1999. He also worked at Alteon, Stratacom, and other technology companies.

Force10 Debuts 10 Gbps Security Platform

Force10 Networks introduced a security appliance that inspects, monitors, captures and blocks traffic at line-rate 10 Gigabit speeds. Force10 Networks said its security platform leverages a Dynamic Parallel Inspection (DPI) architecture for signature processing. The technology employs multiple hardware-based engines to simultaneously process thousands of rules on a single packet. The P-Series directly embeds security rules and signatures into hardware to ensure line-rate processing, inspection and monitoring of traffic on the network. The ability to write new signatures directly to hardware in real time provides IT managers with deterministic, predictable performance regardless of traffic conditions.



The Force10 P-Series family of security appliances includes the P10, a 1RU appliance the offers two line-rate 10 Gigabit ports for an aggregate inspection throughput of 20 Gbps. As a complement to the P10, the two-port Force10 P1 delivers inspection at line-rate Gigabit speeds. The Force10 P-Series supports open source network security applications, enabling customers to specify policies from public domain signatures or standard network monitoring libraries. An open application program interface also allows IT managers to develop custom signatures for firewalling, denial of service attacks and packet and flow analysis applications.



Force10 said it already has more than 20 government organizations, Internet exchanges and national laboratories using P-Series security platforms. Among these are the Amsterdam Internet Exchange, Oakridge National Laboratory, Oxford University, Pacific Northwest National Laboratory, SRI International, Seaton Corp, the Air Force Research Laboratory and the Peter Kiewit Institute.

QUALCOMM and DOJ Reach Settlement in Flarion Gun-Jumping Case

QUALCOMM reached an agreement with the U.S. Department of Justice (DOJ) resolving "gun-jumping" allegations arising from QUALCOMM's acquisition of Flarion Technologies earlier this year. The acquisition was cleared by the DOJ's Antitrust Division and closed in mid-January.



QUALCOMM said that during the Hart- Scott-Rodino review of the transaction, it and Flarion called the DOJ's attention to provisions of the acquisition agreement that required Flarion, in the period before the closing, to obtain QUALCOMM's consent to enter into certain types of intellectual property licenses and other agreements, and to make certain types of customer proposals. QUALCOMM and Flarion said they voluntarily modified some of the provisions to eliminate or reduce the consent requirement. The DOJ has asserted that the provisions effectively gave QUALCOMM an inappropriate level of control over Flarion's business prior to Hart-Scott- Rodino clearance in violation of the Hart-Scott-Rodino Act. The companies disagree with the DOJ's position. The settlement involves the simultaneous filing of a civil complaint by the DOJ under the Act and the entry of a stipulated final judgment. The judgment contains no finding or admission of wrongdoing by QUALCOMM or Flarion. The companies will pay $1.8 million to the DOJ.

TiVo Prevails in Patent Case with EchoStar

A jury in the United States District Court in the Eastern District of Texas ruled in favor of TiVo in its lawsuit against EchoStar Communications. TiVo said it was pleased that the jury found that its time warping patent is valid and that EchoStar has been infringing its
intellectual property. TiVo intends to seek a permanent injunction against EchoStar's DVR products. The jury also awarded $73 million in compensation to TiVo.



In a statement, EchoStar said "This is the first step in a very long process and we are confident we will ultimately prevail. Among other things, we believe the patent - as interpreted in this case - is overly broad given the technology in existence when TiVo filed its patent. We believe the decision will be reversed either through post-trial motions or on appeal. Additionally, the Patent Office is in the process of re-examining TiVo's patent, having determined there is a substantial question concerning the validity of the patent.



DISH Network subscribers can continue to use the receivers in their homes, including their DVRs. Furthermore, TiVo dropped their claim that EchoStar's Dishplayer 7200 DVR infringes their patent. "http://www.tivo.comhttp://www.echostar.com

Intelsat Previews "Super Head-end" for MPEG-4

Intelsat introduced its "Ampiage" -- a new satellite-based, open-architecture, super head-end for North American multiple system operators (MSOs) seeking to upgrade to MPEG-4 and telcos looking to enter the IPTV market.



Intelsat's Ampiage service will handle the acquisition, aggregation, encoding, encapsulation and encryption of licensed TV programming from content providers and has the ability to redistribute it in MPEG-2 or MPEG-4 format to cable and telecom service providers. Intelsat plans to offer hundreds of video and audio channels in full digital quality. Ampiage will leverage Intelsat's Americas' satellite fleet, including its IA-8 satellite, enabling reception in antennas as small as 3.7 meters and providing ample margin for variable environmental conditions.

"Ampiage represents a 'super head-end' that service providers can use to offer the highest quality, reliable content transport, distribution and content management. A small telco would find it difficult to build an infrastructure that has the suite of capabilities afforded by Ampiage at a cost that would yield a profitable business case," said Stephen Spengler, Senior Vice President, Sales and Marketing at Intelsat.

Key Ampiage features will include:

  • Full IP-multicast capability employing the latest advanced video codecs;


  • Hundreds of all-digital video and audio programming channels;


  • Tailor-made solutions for local affiliate stations and regional sports networks;


  • Integrated conditional access solution;


  • Compatibility with existing access networks;

  • Multiple set-top box integration.


Ampiage will be equipped with an open architecture to enable operators to either leverage existing equipment (including set top boxes) or choose new equipment from multiple CPE providers.

http://www.intelsat.com/special/ampiage/index.asp
  • Intelsat's IA-8 satellite, which was launched in June 2005, carries 28 C-band and 36 Ku-band transponders, as well as 24 Ka-band spot beams and will have total end-of-life power of 16 Kw -- making it one of the most powerful communications satellites to date. The satellite will provide coverage of North and South America, Alaska, Hawaii and the Caribbean from its orbital slot at 89 degrees West longitude.
