Atheros (News - Alert) Communications, a provider of innovative technologies for wireless and wired communications, announced it delivered unprecedented performance for its Ethernet-over-Coax, or “EoC,” solution which helps in last mile broadband access.
With the help of Atheros’ AR7400 powerline chipset, cable operators can deliver two-way data services like broadband access, interactive TV and video-on-demand over existing coaxial infrastructures. This chipset provides PHY rates of about 700 Mbps and up to 350 Mbps of actual throughput over coaxial cables.
The AR7400 is designed in accordance to the new IEEE (News - Alert) 1901 draft standard for powerline networking and interoperates with a vast installed base of Home Plug AV products. China’s cable operators, Jiangsu Cable Networks or “JSCN” and Oriental Cable Networks or “OCN” have already adopted this standard into their EoC specifications. These cable operators will deploy Atheros’ EoC technology to strengthen up their existing infrastructure to support next-generation digital TV and broadband services.
The AR7400 is a fourth-generation HomePlug chipset that can deliver carrier-grade broadband transmission over coaxial and power lines. It supports next generation services within the existing infrastructure.
The chipset delivers better throughput and coverage over existing coaxial infrastructures as it is based on carrier certified HomePlug AV technology, which is the baseline technology for IEEE’s 1901 draft standard.
It is currently being integrated into customer premises equipment from leading Chinese device manufacturers like H3C and B-Star.
H3C has completed performance evaluation and interoperability tests of the new Atheros solution. H3C officials commented that the AR7400-based EoC products will soon be a pivotal tool for multi-system operators in meeting the growing demands of China’s NGB requirements.
The AR7400 EoC solution’s remote management feature helps operators configure and scale systems to suit building size, range and subscriber population. It supports more than 700 meter coverage through multiple splitters and required throughput speeds.
Todd Antes, vice president of marketing, Digital Home of Atheros Communications, said, “Service providers require standardized technologies that are field-proven and cost effective. Adoption by leading carriers not only validates the performance of our AMP products for EoC applications, but demonstrates the growing momentum behind IEEE 1901 as the technology of choice for wireline networking in the home”
In February at this year’s Mobile World Congress (News - Alert), Atheros Communications showcased its latest mobile technologies, connectivity features and applications, including the single-chip 802.11n AR6003, a mobile WLAN solution; AR1520, the company’s third-generation, single-chip GPS receiver; and the AR6133, Atheros’ smart combination of mobile 11n and Bluetooth 3.0 technologies for consumer electronics applications.

Yitran’s Technology Featured Inside Smart Grid Technologies Pavilion at the Shanghai World Expo 2010
Yitran’s Powerline Communication (PLC) IT700 technology is featured by the Chinese State Grid Corp. in their pavilion at the Shanghai World Expo 2010. The pavilion shows Smart Homes and Smart Buildings as part of the smart grid vision and innovations that will be integrated into China’s future. Yitran’s PLC technology is featured in the smart sockets connected to intelligent home appliances for energy management purposes and in home displays that provide accurate real-time status, feedback and analysis of the energy usage profile in the home.
Yitran’s PLC networking chips are used to provide the networking between smart sockets and the in-home display panel. The Expo pavilion features, for example, household appliances attached to smart sockets, which measure the power consumption different devices and sends that information via PLC to a display in the home so that the consumer can easily see the energy consumed by each device used. This allows the consumer to understand their home’s energy profile, which in turns allows him/her to respond to changes in electricity prices and receive rebates from the power utilities for allowing the use of energy management system in the home. This same networking technology can also be used to send gas and water consumption information to the same in-home display, using a combination of wireless and PLC networking technologies. Please visit the Yitran site for photos from the pavilion.
Yitran currently offers its IT700 PLC modem chip, which features an extended 8051 MCU core, offering a high level of code efficiency and high speed operation. The microcontroller and the transceiver along with the analog front end (AFE) are integrated into a plastic molded QFN56 package. IT700 complies with worldwide regulations (FCC, ARIB and CENELEC bands) and is fully back compatible with the IT800 series.
The Chinese State Grid Corporation has invested a great deal of time and money over the last several years to cope with the ever increasing demand for electricity by planning to integrate various energy and smart grid technologies into China’s future. The display at the Shanghai World Expo is designed to give visitors an opportunity to learn more about the smart grid concept as well as the key areas of the State Grid Corporation’s smart grid pilot projects and their results.
