Making Zigbee wireless modules smaller, cheaper, better

Moscow, Russia – MeshNetics is working with Atmel on an half inchsquare IEEE802.15.4/ZigBee OEM module that it claims is half the sizeof comparable products, opening up the way to lower cost, more portableand easier to use implementations of the wireless control networktechnology.

According to Vasiliy Suvorov, Managing Director and CTO of Meshnetics,as the IEEE802.15.4/ZigBee market grows, OEMs fuel demand forIEEE802.15.4/ZigBee modules and single chips. “Developers are facedwith a choice in wireless connectivity implementation: either add amodule to the system, or integrate a single chip to the boardcircuitry,” he said.

“The module approach offers numerous advantages. The module alreadycontains the complex RF design with the necessary passive componentsincluded, freeing the OEM from the time-consuming development. Themanufacturer can instead focus on its core business without the need ofhaving an RF expertise.”

Measuring 1.88cm x 1.35cm (0.74″ x 0.53″), the Zigbit¬† module isbased on an 802.15.4 hardware platform being developed by Atmel.It is supported by MeshNetics software containing the company's eZeeNetnetworking stack software, based on IEEE802.15.4 MAC layer and isZigBee network capable.

Suvorov said the eZeeNet stack allows the module-based wireless sensordevices to form self-healing, self-organizing mesh networks that arewidely used inindustrial monitoring, HVAC control, automatic meter reading, and more.A power-management feature, included in eZeeNet stack, is crucial, hesaid, inextending the battery life of wireless devices.

 The ZigBit module will have three antenna options, i.e.integrated chip antenna, antenna connector, and balanced RF output foruse with the PCB antenna. An evaluation kit, to be available nextmonth, will contain interface boards, accessories, and softwarepackage, including network configuration tools and a sample dataacquisition application.
