Neul Launches First White Space Radio System
Cambridge UK company Neul and California partner Carlson today launched the first commercially available white space radio system created for wireless internet service providers.
RuralConnect unveiled in Florida is the first radio networking system to deliver the full promise of TV white space broadband to the providers.
Sales of RuralConnect are being managed in the US by Carlson, the hardware partner, and shared internationally with software aces Neul.
The product launch follows the announcement of a global partnership in last October and is aimed at bringing affordable broadband to millions around the world.
The system will give users up to 16 Mbps of bandwidth for each available vacant TV channel and unmatched ability to make long range, non-line-of-sight links.
Designed specifically for the needs of wireless Internet service providers (WISPs), RuralConnect has been priced to make it immediately commercially viable. Samples and development kits are available now, with volume shipments of the new system to start as soon as Q2, 2012.
Thanks to the extension of the Payroll Tax Bill, passed in February 2012, white space radio is now fully available in the US, opening up a host of opportunities and new markets that are currently difficult to serve without expensive licensed spectrum or extensive infrastructure.
This has piqued the interest of many investors and venture capitalists looking to tap in to the unlimited possibilities of this emerging technology.
RuralConnect technology, jointly developed by Neul Business Weeklys newly-chosen Wireless Business of the Year and Carlson, uses white spaces, (unused portions of UHF spectrum), for digital communication.
Due to its outstanding propagation characteristics, UHF signals can travel through walls and other obstacles: Line of sight is not needed to the subscribers home.
But it is not enough just to be able to send a signal a long way. On long-range links reflections from buildings and terrain cause signals to travel via many different routes from the transmitter to the receiver. These multipath signals interfere can with each other, potentially causing unreliable, slow connections.
RuralConnect uses state of the art SCFDE technology to cancel the effect of multipath allowing reliable long range connections, whatever the terrain.
As a result WISPs using the new system can offer superior coverage over wide areas with limited base-station sites. It also enables the transfer of more data at higher data rates, driving additional revenue with minimal additional investment. Depending on the area, up to 20 channels are available, increasing the amount of non-line-of-sight capable spectrum available by a factor of 10.
Concurrently, Carlson is launching a line of omnidirectional and sectoral, high-gain, base-station antennas designed specifically for TV white-space broadband. The first of their kind, these antennas are powerful, affordable and energy efficient, says Neul CEO James Collier.
“RuralConnect marks a major milestone in the realisation of white space technologies, which have been in development for a while,” commented Luke DArcy, VP of Marketing at Neul.
“The outstanding propagation characteristics of white space signals means that operators can to serve customers they cannot reach with existing wireless technology.
“The capacity available allows pioneering WISPs to offer all customers faster plans that beat ADSL based competition. And this is possible without investing in new tower sites, spectrum licenses or high priced network equipment, boosting profitable growth.”
Carlson and Neul are showcasing the new product at ISPAmerica in Florida, until March 30.

HDBaseT in HDMI Extenders Over Cat5e/6/7 Cable
The main drawback of HDMI as an A/V connection standard, when it comes to high definition video distribution, is cable length limitation. Installation costs quickly add up when you consider HDMI cables, control cables and HDMI repeaters for solving distance limitation. To cope with this limitation, a multitude of HDMI extenders over standard cat5e/6 cable became available each of them providing proprietary solutions to support HDMI extension along with different control signals including CEC, IR, RS232, USB. The downside in all these implementations is that 150 feet proved to be the maximum distance for 1080p/24bit/60Hz resolution, with full HD support guaranteed well under 100 feet. With growing popularity of 3D formats, the need for a new technology became apparent.
HDBaseT is a new connectivity technology optimized for home and commercial multimedia distribution promoted by HDBaseT Alliance. The cornerstone of HDBaseT technology is the “5Play” feature, which means transmitting full uncompressed high definition video, audio, 100BaseT Ethernet, power, and various control signals through a single standard 100m/328ft Cat5e/6 solid cable. HDCP is also handled by the technology.
HDBaseT supports TV and computer video formats including standard, enhanced, high definition and 3D video, as well as all audio standards. HDBaseT delivers full HD/3D and 2K/4K uncompressed video in a point to point connection or a single to multipoint distribution supporting both daisy chain and star topologies. When cascading, extension limits can go beyond 100m/328ft up to eight additional 100m/328ft runs can be combined. This flexibility makes HDBaseT an ideal commercial technology for applications such as digital signage.
HDBaseT supports 100Mb Ethernet, enabling televisions, hi-fi equipment, computers and other devices to communicate to each other and to access stored multimedia content. Different types of control signals are also supported by HDBaseT technology, starting from Consumer Electronic Control (CEC) that operates basic functionality such as power-on, power-off play and stop, to RS232, USB and infrared (IR) that operate remote equipment even when located in a different room. This large variety of control signals gives equipment manufacturers and integrators the flexibility to choose the solution that best meets their needs.
The latest addition to the HDBaseT 1.0 specification is Power over HDBaseT or PoH. This enables the transfer of DC power, along with data signals, over a single Ethernet cable in a manner similar to Power over Ethernet (PoE). PoH safely delivers up to 100W over four pairs of Ethernet cable, which allows power to be supplied to the attached devices through the cable, requiring no additional power supplies. The latest Energy Star 5.3 Specification restricts all TVs to 108W of power consumption, regardless of screen size. Energy Star 6.0 Specification targets a cap of 85W for all TVs. At these levels, HDBaseT has ample power delivery capabilities for supporting even large displays.
Network Technologies Inc (NTI) integrates the HDBaseT technology into its new line of HDMI extenders. The ST-C6HDMI-HDBT extender supports full HD/3D extension to 328ft, HDCP, CEC, IR and optionally SPDIF. The ST-C6USBHE-HDBT supports all of the features listed for ST-C6HDMI-HDBT, plus 100BaseT Ethernet, RS232, and USB support for USB keyboard/mouse and an additional USB device, such as a USB touch screen monitor, USB CAC card reader or USB whiteboard. Both extender models require only one power supply to power the local and remote units, which can be attached at either end. SPDIF audio and USB are not standardized in HDBaseT technology; therefore NTI employs proprietary solutions in its extenders. The way power is delivered through the Ethernet cable is also a proprietary approach tailored to extender applications and provides flexibility at a lower cost.
