From the beginning, SenzaNET was designed with standards adherence and customer investment protection in mind. SenzaNET is fully compliant with the IEEE 802.15.4 standard, which is stable and widely accepted in the industry. IEEE 802.15.4 defines the physical and MAC layers of the system, but does not specify topologies. Different topologies require different routing protocols, and even within the same topology class, routing, networking, and transport schemes vary due to the existence of multiple upper layer standards. ZigBee, WirelessHART, ISA100, and 6LoWPAN are examples of existing and future standards that build on IEEE 802.15.4.

As the architectural foundation of E-Senza’s products, the SenzaNET framework is therefore designed to not only conform to its own mesh routing algorithm, but to allow for plug-ins for WirelessHART and 6LoWPAN. This provides customers with choices to appropriately balance technical and time-to-market requirements. The SenzaStack (SN100) version delivers a “WirelessHART lite” solution with lower algorithmical complexity. It therefore requires less memory resources, is easier to analyze and troubleshoot, and provides better performance in areas such as mesh formation time. For those requiring a fully compliant WirelessHART solution, the SNH7 stack and a WirelessHART API are offered. All SenzaNET system components are firmware upgradeable for easy migration to the latest mesh technology, as it becomes commercially available.  

E-Senza is an active member of the HART Communication Foundation, and also welcomes and supports the standards efforts of the Internet Engineering Task Force (IETF).
