Zigbee Range Extenders Generic Term being used by Vendors to describe devices that extend a 2.4 GHz Zigbee signal around obstacles or to large distances– (based on RF characteristics) Some vendors are interchanging the term Extender with repeater, router, relay – depending on their architecture Two connectivity characteristics: 1. Extenders that are unsecured and whose function is to extend the broadcast range between one ESI and secured devices. Typically do not have any logical functionality built into them and thus no connectivity details. These type of extenders provide neutral signal amplification between an ESI and HAN device(s) and will not occupy a HAN device allocation slot provide by a utility ESI. It provides “open” communication support. 1b. Extenders that are unsecured and whose function is to extend the broadcast range between multiple ESI’s and multiple secured devices. All other characteristics are the same as Number 1 above. 2. Extenders that are secured whose function is to extend the broadcast range between two secured devices. Extenders that require a secured trust link between an ESI and a HAN device. These type of extenders will occupy a HAN device slot provided by the utility ESI. Typically single network specific (other networks’ devices can’t hop through) Note: Vendors development focus seems to be in this group. Note: A wireless range extender works as a relay or network repeater, picking up and reflecting WiFi signals from a networks access point. The Network performance of devices connected through a range extender will generally be lower than if they were connected directed to the AP.
Texas HAN Requirements - 2009 BR-025 – Cancelled – Not Needed Ability to provision a HAN device to more than 1 ESI at a time, unless the TDSP precludes this from happening. SEP 1.0 – Only one device to one ESI at a time. SEP 2.0 – Multi-ESI in discussion only. Not approved and no development being done.
