Laird Technologies published a new white paper, Moving Beyond Zigbee for Star Networks. The technical paper addresses the requirements of star networks, and the need of finding the correct wireless solution beyond traditional means. The white paper details the data flow through a network, and how most networks that are point-to-multipoint (or multipoint-to-point, depending on the perspective) form a star topology. The technical paper also presents possible solutions and features a model comparison of some of the key attributes of a Laird Technologies LT2510 100 mW transceiver versus a typical Zigbee 10 mW transceiver.
Moving Beyond Zigbee for Star Networks Introduction
Multi-hop mesh protocols, such as Zigbee, are getting a lot of press for their ability to link together low data-rate Machine-to-Machine (M2M) applications. Zigbee, in particular, is targeting itself as the standard bearer for wireless, low-power meshing protocols. Many of the features of a Zigbee solution touch on the requirements for expanding wireless M2M markets. Low data rate, low power, enhanced range through the mesh and automated on-demand routing of packet data are the key aspects of Zigbee which are responsible for creating such a buzz in the M2M market space.
Moving Beyond Zigbee for Star Networks Summary
Star networks present unique challenges, from managing the number of end nodes, ensuring connectivity, and balancing data from and to the source point. These challenges are enough without adding the unnecessary overhead from a multi-hop mesh solution. Star networks can benefit from a simpler, more effective solution. Zigbee has some great features which make it a powerful protocol for M2M communications, but that does not mean it is optimized for all networks. Identifying the key requirements and selecting a wireless solution which is optimized for star networks can reduce the time to market and also provide for a more robust solution.
