Jennic has introduced JenNet, a free proprietary wireless networking stack for its range of 32-bit single-chip wireless microcontrollers.

Based on the IEEE802.15.4 standard, it is specially designed to be easy to use and is fully scalable from just a few nodes to large networks of up to 1000 nodes.

Complementing the company’s existing ZigBee stack which provides interoperability with other ZigBee devices and mesh networks, it addresses a wide range of applications, including street lighting systems with long strings of nodes and large building management systems.

JenNet addresses many of the issues found by developers when creating wireless sensor networks, including the ease with which this functionality can be added to their products. It does this by providing users with an easy application development path through its two simple programming interfaces, Jenie and AT-Jenie.

With its small memory footprint, which can be as low as 16 kB, JenNet ensures that up to 80 kB application space is available for a 100-node network.

A range of network topologies is possible, including star, tree or linear formations that can accommodate long strings of nodes. Self configuration and automatic healing ensure that networks constructed using JenNet are tolerant of node failures.

It also supports sleeping end devices for multi-year battery life, encryption of packets for secure data transmission and over-the-air download for easy updating of nodes. Since it is based on the IEEE802.15.4 standard at 2.4 GHz, it offers coexistence with Wi-Fi and Bluetooth.
