LONDON – Xsilon Ltd., a 2008 startup, has announced it is offering in-home machine-to-machine powerline communications technology.
Xsilon (Bath, England) is developing a physical layer circuit to operate in the 2- to 30—MHz carrier range. The technology is named Hanadu from HAN standing for home-area network.
Key application areas for Hanadu include smart meter connectivity in mainstream environments as well as in difficult building deployments, in-home energy management solutions, appliance monitoring and maintenance applications, and telemedicine services.
Ad hoc topologies are supported with auto-discovery routing algorithms, and the bandwidth scales to support many dozens of connected end-points within a single home or building. Xsilon claims it can achieve radically lower power consumption for a powerline modem, a tenth of the typical 4 to 5-watts, and a small form factor that would allow it to be included within an electricity plug or small consumer equipment. The Hanadu system includes network security to maintain householders' privacy, the company said.
Xsilon said it has generated its own intellectual property in designing Hanadu, and it will be opening the technology up to standardization activities in the near future.
First products will allow vendors and service providers to evaluate the connectivity advantages of Hanadu technology, followed by connectivity modules for integration into OEM products. Dual-mode solutions are also being designed, allowing deep integration with other connectivity solutions such as WiFi, ZigBee and Ethernet.
The HAN9000 Connectivity Evaluation Kit will be ready for shipment to customers in 3Q12. It uses a modular design to accommodate the varying needs of different customers. Each CEK unit is approximately 27-cm by 13-cm in area, which encompasses all the network interface technology, power supplies and data processing modules. Accompanying software allows connection throughput and link integrity to be logged, monitored and analyzed. Early applications will be addressed by Xsilon’s first connectivity product, the HAN1250 module which will launch in 2013.
Xsilon person, There is no technical data on your web site and consequently it is impossible to determine what issues you have taken into account to minimise the ever increasing pollution of the HF spectrum with no consideration for existing users. Technically I am certain that your product may work. Can you be more specific about how your product works and as to what steps have been taken to minimise interference to existing users of HF resulting from mains cable radiated RF.
John.Nowell and Master Ice can rest assured about RFI in HF. We're well aware of these issues, and we've taken them into account. We benefit from not having to support/interoperate with a legacy product set, so our hands aren't tied. Moreover, we designed our modem after the RFI problems of older powerline became clear, so we were able to design around those problems.
If wireless did the job, we'd let it get on with it ! Fact is, wireless really struggles in the home, especially in the nooks and crannies where we tend to hide our appliances out of sight. Setting up wireless connectivity in those positions is a real challenge, which is why we've opted for powerline. And we're no more expensive than ZigBee. And we're good citizens on the RF front.
