SkyCross Unveils iMAT Single Antenna

SkyCross unveiled its Isolated Mode Antenna Technology (iMAT) single-antenna approach providing MIMO capabilities.


SKyCross said its revolutionary antenna design will enable designers of handsets, PC cards, USB dongles, personal navigation and other wireless electronics to offer diversity or multiple input, multiple output (MIMO) communications, even in applications where such implementation has been considered impossible due to space constraints inside mobile devices. Traditionally, MIMO leverages multiple antennas at both the radio transmitter and receiver to improve communication performance. Next-generation protocols, such as HSxPA, WiMAX, 802.11x, and LTE, all of which require diversity or MIMO.


The single-antenna solution from SkyCross eliminates the need to configure multiple antennas and reduces the number of parts required to build a device. The company said its iMAT enables a single device antenna to perform like multiple antennas through the use of multiple feed points. Each feed accesses the antenna as if it consisted of multiple antennas, each with high isolation, low correlation, and high per-feed antenna efficiency. The multiple radiation patterns produced by an iMAT antenna have low correlation so they cover different spatial regions to achieve pattern diversity and signal independence. This makes the way the device is "pointed" with respect to towers and base units less crucial.http://www.skycross.com

NXP Launches Ultra-low Power Multi-band Silicon Tuner for Portable TV

NXP Semiconductors introduced a multi-band silicon tuner (TDA18292) that supports the five global TV standards for portable devices (DVB-T, DVB-H, DVB-SH, T-DMB, ISDB-T) and five prominent frequency bands (VHF, UHF, L1, L2, S-band).


NXP said the ultra-low power, low noise, small footprint and high immunity to other cellular and connectivity standards, makes the new device an ideal TV solution for notebooks, USB sticks, Portable Multimedia Players (PMP), portable DVD players, mobile phones, portable navigation systems (GPS) and other handheld devices -- at a very low cost of less than $2, for high volume quantities.http://www.nxp.com

Strix Systems Introduces Wireless Mesh Video Surveillance System

Strix Systems and Dotworkz Systems announce a high-performance Integrated Wireless Video Surveillance System (IWVS) designed for optimal IP video surveillance over wireless/WiFi mesh networks.


Strix Systems' hardware and software have been integrated into the Dotworkz D2 weatherized enclosures for IP-enabled Intelligent Pan-Tilt-Zoom (PTZ) cameras. High throughput and low latency are achieved via Strix intelligent radio algorithms that dynamically adjust to the environment. Maximum power enables the greatest signal strength, receive sensitivity and optimal channel selection for the most robust wireless connectivity and highest achievable throughput.


The IWVS includes high power 802.11a and also supports high-power 4.9 GHz for public safety deployments. 802.11a and 4.9 GHz radios provide secured/encrypted WiFi access to the wireless mesh network. IP Video is switched at high-speed between radios and the IP camera connected Ethernet port while Strix Virtual/One and Strix Priority/One provide packet prioritization and Quality of Service throughout the network. Layer 2 Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP) enable self-configuration which is fully manageable by Strix Systems Manager/One and a compliment of iSNMP (Simple Network Management Protocol) managers. Video and recording management is enabled by the IP video surveillance camera and/or client-server application of choice. The IWVS optionally includes an 802.11g radio for localized wireless client/user access supporting voice, video and data applications.

Indonesia's Global Mediacom Selects Nokia Siemens for Mobile TV

Indonesia's Global Mediacom has selected Nokia Siemens Networks to launch a commercial broadcast mobile TV service based on Digital Video Broadcast-Handheld (DVB-H) technology in the first half of 2008. The deal is the biggest DVB-H agreement signed by Nokia Siemens Networks globally to date. Financial terms were not disclosed.


Nokia Siemens Networks Indonesia is responsible for the end-to-end systems and services, which will include consulting, implementation of the entire broadcasting solution and network, systems integration and the relevant business applications. Global Mediacom is also in discussions with Nokia for Nokia to provide DVB-H integrated devices such as the Nokia N77, and work with Nokia Siemens Networks on joint marketing activities to ensure service adoption by Indonesian consumers.http://www.nsn.comhttp://www.mediacom.co.id/

Ubiquisys Offers Femtocell System for Small Offices

Ubiquisys introduced new femtocell systems for small and medium-sized businesses based on its residential product. The ZoneGate E2 modular femtocell system enables Mobile Network Operators to provide users with their own private 3G network access point for better indoor coverage.


The ZoneGate E2 is a modular femtocell system that can be used individually or or in a formation to cover various office layouts. Irrespective of the deployment formation, the femtocells dynamically adapt the coverage between them, and automatically manage handover as employees move around the office whilst on a call. The system connects to the mobile operator's core network through the existing broadband connection.


"Femtocells have long been thought of as a consumer device that provides better quality lower cost mobile coverage in the home - this is no longer the case. Mobile operators can now extend these innovative services to businesses as well." said Will Franks, CTO Ubiquisys.http://www.ubiquisys.com

NTT America Announces Carbon Offset Program

NTT America announced a program designed to offset carbon dioxide emissions generated from the use of NTTA's enterprise hosting and co-location services. The program will be offered through a partnership with TerraPass, which provides carbon offsets by investing in green technologies.


Through its relationship with TerraPass, NTTA has calculated the estimated amount of annual power and resulting carbon pollution that enterprise hosting platforms and co-location services emit in a year. All emissions calculations are based on the World Resources Institute (WRI) Greenhouse Gas Protocol, an international accounting tool for greenhouse gas emissions.


The fee charged for TerraPass carbon offsets is used by TerraPass to fund carbon reduction programs. These programs include wind farms, farm power generated from methane gas digesters and landfill gas capture.


NTTA said its customer carbon off-set program is one of several Green Initiatives being undertaken by NTTA in data centers within the United States, and globally by NTT Communications.
