RF Mesh Technique

1. According to Wi-SUN FAN specification allows seamless interconnections between smart-grid devices produced by different suppliers.

2. Wi-SUN based wireless equipment operates in frequency bands below 1GHz, even in the presence of interference and some types of obstacles.


3. A big advantage of Sub-GHz wireless communications is that it can be implemented with extremely low levels of power consumption compared with other wireless communications.

Wi-SUN wireless adopts the IEEE802.15.4g standard for physical layers, and can maintain communications even in environments that have over 1000 nodes. Its MAC layer conforms to IEEE802.15.4e.


4. It achieves improvements in throughput and security compared to wireless networks based just on IEEE802.15.4.


5. It has long-distance transmission and low power consumption to meet the demand of smart grid and IoT market

6. It supports IPv6, effectively improving interoperability and security in IoT applications

Willfar’s wireless RF mesh architecture offers utilities a cost effective and simplified path towards upgrading field communications to enable more demanding utility field automation applications.




The WFET-7000E/S gateway support at least the following functionalities:


a) Auto-detection of new meters in the grid

Automatically discovering new meters and ready to dynamic topology changes.


b) Meters network management

Able to manage the link and control all associated meters. Besides, DCU shall have the ability to get the node RF network status (online, offline) and the FAN network topological graph.


c) Time synchronization

Support synchronization of the RTC from the centralized server like NTP or HES.


d) Gateway functionality

Able to provide a direct transparent link to the end meters from HES. This function allows HES to get a real-time data directly from any meter it connected to, by end-to-end secure gateway functionality.


e) Automatic collection of meters data

The Gateway forwards meter consumption data to HES in an automated manner. This function allows an automatic meter reading delivery to up level AMI elements to exchange. Automatic data sending should be based on Schedule, Events and Requests.


f) Alarm management

It manages meter tampering or inform about any event and alarm regarding the service. Alarms and Messages especially fraud detection, rewiring, and power off and on shall push to HES automatic.
