NTT Develops 60 GHz Transceivers Delivering 15 Gbps

Researchers at Nippon Telegraph and Telephone Corporation (NTT) announced the world’s smallest wireless transceivers that cover all four of the channels*1 allocated in the 60-GHz band.

The 60 GHz transceivers have a maximum transmission rate of 3.8 Gbps per channel. Simultaneous four channel transmissions makes the transmission rate about 15 Gbps.

NTT said the 60 GHz technology could be used in kiosks located in public venues that would wirelessly download of gigabyte-class content (e.g., a DVD of 4.7 GB) in about 10 seconds,

In Japan, as per the revisions to the Radio Act in September 2011, four channels without licenses can be used for such an application.

The miniaturized transceivers are packed in a wireless module in which a broadband antenna and MMICs are integrated in the multi-layer LTCC substrate. It can cover all four channels.

Crossbeam and Spirent Emulate More Than 1 Million Mobile Users

In tests conducted by EANTC, Crossbeam and Spirent Communications were able to emulate more than a million simultaneous mobile subscribers using their smartphones and tablets. The significance of the test is that the companies were able to simulate the effectiveness of network security devices and how they perform under real-world conditions.

Specifically, the test replicate the traffic loads that carriers experience at the mobile Internet gateway (Gi/SGi). Spirent's Avalanche plat form was used to emulate more than 1 million users concurrently accessing the mobile data network with their connected devices. The traffic was sent through a single Crossbeam X-Series X80-S platform running Check Point software, where it underwent a series of firewall and IPS (intrusion prevention system) inspections, as well as network address translation (NAT). The real-world traffic model included using a 95 percent majority of HTTP sessions representing a range of user profiles. In addition, email (SMTP and POP3) connections were emulated alongside Smart Phone OS over-the-air updates.

“With so much misleading information about security product performance and the unpredictability of threats and traffic demands, there has been no clarity around what to test for and what methodology to use,�? said Chet Gapinski, vice president, product development at Crossbeam. “Any single measurement, such as network throughput, is meaningless unless tested and measured in combination with other metrics under real-world conditions. We saw an important opportunity to work with Spirent and EANTC on a set of real-world tests to move the industry forward to provide more accurate, uniform guidance."

SOPA Internet Strike -- January 18th

A collection of websites, including Wikipedia's English language pages, Mozilla, TwitPic, BoingBoing, and Reddit, are conducting a one-day blackout to voice their opposition to the proposed "Stop Online Piracy Act and the Protect Intellectual Property Act," which is under consideration by the U.S. Congress. Organizers argue that SOPA imposes unwarranted restrictions on free speech across the Internet and that it will enable major corporations to assert copyright claims without any due process in the courts.
  • Much of Wikipedia's content is likely to still be accessible during the strike via Google's cache.

China Mobile and Clearwire to Hold Joint TD-LTE Device Testing

China Mobile and Clearwire, in conjunction with the Global TD-LTE Initiative (GTI), announced an agreement on common test specifications and joint interoperability testing (IOT) for TD-LTE devices in the global band configurations, including 2.3GHz to 2.7GHz. Plans call for establishment of 4G mobile broadband labs featuring a joint test platform and IOT environment for TD-LTE devices. The labs will allow for the evaluation and qualification of commercial TD-LTE devices simultaneously in the U.S., China, and other promising markets, using common testing methodology, equipment, and infrastructure.

The collaboration is expected to accelerate development of the TD-LTE device ecosystem, especially in multi-mode, multi-band LTE devices. The carriers said the expected availability of the Quad-Band LTE 2.3-2.7 GHz spectrum range, in addition to certain other bands like 1.9GHz, as well as FDD and TD-LTE mobility interactions, makes it an ideal global configuration for mass 4G marketing worldwide.

“The unmatched spectrum portfolio underlying Clearwire’s planned LTE network has the potential to deliver faster speeds and with greater capacity than any current or proposed 4G network in the United States,�? said Dr. John Saw, chief technology officer of Clearwire. “Close collaboration with global wireless leader China Mobile accelerates the development of multi-mode multi-band TD-LTE and LTE FDD devices and provides the common test specifications OEMs, ODMs, chipset vendors and other critical component manufacturers need to rapidly develop and commercialize products to serve this massive global marketplace.�?

“Converged with LTE FDD, TD-LTE has become the major global 4G technology for unpaired spectrum,�? said Mr. Li Zhengmao, Vice President of China Mobile. “Our goal is to build efficient, low cost common infrastructure and terminal for different global markets with different spectrum to support mobile internet. By closely working with global operators such as Clearwire, we could leverage the experience, expertise, and scale to achieve this goal. This is also the reason why we create GTI and promote it jointly�?.

Clearwire plans to conduct its TD-LTE common IOT in Phoenix, AZ and Herndon, VA. China Mobile’s testing will be carried out in Beijing and other TD-LTE trial cities.
  • In September 2011, China Mobile and Clearwire announced a collaboration to accelerate the development of TD-LTE devices. Specifically, the carriers will work jointly to further accelerate the time-to-market availability of high volume TD-LTE chipsets and devices that should be commercially available starting in 2012. In addition, the two companies will collaborate to enable worldwide data roaming among TD-LTE, FDD-LTE and other 2G/3G networks. Both carriers support the global 2.5 GHz spectrum band for 4G deployments along with many other operators around the world. To date, both China Mobile and Clearwire have conducted successful TD-LTE trials and tests using commercially available/production-ready TD-LTE devices from numerous vendors.

  • In August 2011, Clearwire confirmed its intention to deploy "LTE Advanced-ready" technology in its 4G network while restating its commitment to its existing 4G WiMAX network, which covers approximately 132 million people while serving 7.65 million retail and wholesale customers. The company expects to end 2011 with approximately 10 million 4G customers. Clearwire said the initial LTE deployment will target densely populated, urban areas of its existing 4G markets where current 4G usage demands are high. Clearwire said its LTE network will be "LTE Advanced-ready," meaning that it will use spectrum configurations capable of 100+ Mbps downlink speeds.

Sensory Networks introduces DPI Software for Low-end Device Market

Sensory Networks has extended and optimized its "HyperScan" pattern matching and deep packet inspection (DPI) acceleration software to provide high-speed content inspection on a range of low-cost, low-power processors used in networking and security products. The HyperScan pattern matching software has now been optimized for Intel Atom, Broadcom MIPS and ARM architectures. The DPI technology can now be extended to SMB and SOHO products that include Wi-Fi routers, Firewalls, IPS/IDS, UTM appliances and other network access devices.

“We now have several customer engagements where HyperScan is being used for DPI in low-end and ultra low-end devices, said Sab Gosal, CEO for Sensory Networks. “The low-end market segment has become so cost sensitive that equivalent hardware solutions simply cannot meet the price/performance requirements.�?

"HyperScan scales well to this class of device, delivering 400-500Mbps of scanning throughput per core, for a range of IPS and Anti-Virus use-cases, using a 1.6GHz Intel® Atom™ 230 processor", said Geoff Langdale, CTO of Sensory Networks. "Content inspection throughput improvements on resource challenged machines are only one part of our advantage. We have also aggressively reduced compiled byte code size and provided the ability to serialize and cross-compile pattern databases across different architectures. This ensures that it is practical to use our DPI technology for devices with very low provisioning of memory, storage and CPU cycles".
