New smart repeater triples wireless sensor signal range

Pressac Communications, a UK manufacturer of smart sensor technology, has launched a wireless, low-energy repeater to triple the wireless range of EnOcean-enabled sensors over greater distances or where obstructions occur within buildings.
The Pressac smart repeater is a cost-effective way to increase a sensor’s range. It receives messages from EnOcean devices and then retransmits them wirelessly to any number of selected devices. It can extend the EnOcean wireless range from 30 meters up to 90 meters inside a building, depending on the configuration and the building.
Standard RF range for EnOcean devices is 300 meters within the line of sight (LoS). Once a device is installed inside a building, this may be reduced, depending on the building materials used. Using a repeater can double or, if two repeaters are used, potentially triple the distance of the signal, thus offering a low-cost way to extend the range of devices and collect data from a wider area within a building.
The EnOcean-compliant repeater is mains powered via 5V USB and is compatible with EnOcean products. It also has an option for selective repeating, letting you choose which sensors to repeat in order to minimize unnecessary data being transmitted.
Many other repeaters simply repeat every message they receive, which then causes issues with too many messages being needlessly retransmitted. The smart repeater doesn’t have this problem because it’s designed with the ability to select which devices are repeated.
