Toppan Printinghas enhanced its communication module for the Zeta IoT low power wide area networking protocol with over the air (OTA)updates.

The Zeta protocol was developed by ZiFiSense in Cambridge and Shanghai and combines a bidirectional Ultra Narrow Band (UNB) link and distributed access with a self-healing mesh topology.

Toppan sees Zeta gaining attention as a form of communication infrastructure for low-data-volume sensor devices, such as those for temperature, humidity, and voltage. The mesh network enables stable wireless communication in locations in which connection using other LPWA networks can be problematic, such as factories with complex layouts and office buildings with underground facilities.

Toppan’s TZM902 module is approximately 25 percent smaller than the previous model as the result of a redesign around a system on a chip (SoC) to reduce the number of components, use of smaller components, and removal of the antenna connector. The Zeta Alliance is working with chip designerSocionextSoC设备的协议。
