Document Definition:
It defines the specifications (i.e., introduction, technical features,
deployment, and maintenance methods) of the WiSenMeshWAN® Smart Gateway, which
is one of the key components in the WiSenMeshWAN® Low Power, Intelligent,
Wireless Sensor Network (WSN) Monitoring system. It is responsible to:
- Form a time-synchronized WSN with all the nodes in the system;
- Receive the data packets from all the nodes including sensor nodes and interface nodes;
- Issue network command in order to optimize the network reliability, such as sampling interval, frequency hop, relay period, RSSI threshold modifications, etc.;
- Forward data and system information to a Windows laptop.
Scope:
Customer Site Project Managers and Engineers, Wisen Service Engineers, etc.
Product Introduction
ABC The WiSenMeshWAN® Mini Smart Gateway is one of the key products in
our patented WiSenMeshWAN® geotechnical safety monitoring system. Working
together with the WiSenMeshWAN® Node products, it intelligently collects,
converts, and delivers real-time information from nodes to a local PC via a
standard USB connection. The WiSenMeshWAN® Mini Smart Gateway is powered by a
USB port (5VDC).
This product operates using our core technology, i.e., WiSenMeshWAN® Low
Power, Intelligent, Wireless Sensor Network protocol. This product satisfies
the three fundamental identities of the system:
A. Network Life Span: to maximize battery life across the mesh network as a
whole;
B. Network Data Arrival Rate: to minimize data packet loss;
C. Single Node Environmental Coverage: to maximize radio coverage.
Our product is small in size, reliable in performance, easy for maintenance, and has a strong immunity to radio interference.

Gateway Terminologies
Operation Procedures
Gateway Location Choices
Location: There are two fundamental considerations that are used by Wisen to identify an available location for a Gateway:
- Firstly, mesh coverage is the primary factor to be considered. It is vital to arrange the wireless mesh topology so that all the nodes in the system are connected. The recommended location of a Gateway is in the center of the network;
- Secondly, Mini Smart Gateway should be closed to the PC or industrial computer. Make sure the USB cable is as short as possible to reduce interference;
- Serial Numbers of a Unit must be recorded against their site references; Once the location is chosen, you are ready to deploy your WiSenMeshWAN® system.
Deployment Procedures
- Antenna Installation: screw the antennas firmly onto the Mini Gateway;
- Power on: Connect the USB cable between Mini Gateway and PC; LED flashing sequence: You should see three Mesh LEDs flashing 3 times, then the green LED on for 1s, then a quick flash on the 3 LEDs, then Off. If not, unplug the gateway (to power off), and leave it fully discharged for 180s before the next powering-on.
- The gateway should have its antennas point upwards;
- Open WISENMESHNET Standard Serial Port Monitoring Software on Windows PC to validate the gateway data.
General Maintenance and Notification
- Once the WiSenMeshWAN® Smart Gateway is installed and working, please do not interfere with it unless it is absolutely necessary;
- The Gateway relies on radio signals to communicate with the nodes. It must be deployed before the nodes and please ensure that it is not covered by any materials, which would block the radio signals, for example, chicken wire, aluminum sheet hoardings, etc.;
- If no data is received from the Gateway, then please carry out investigations in the following two stages:
A. Remote Inspection of historical data, to identify:
a) Whether the heart-beat message has been sent back successfully at each time
interval;
b) Whether the voltage in the heart-beat message is as expected, if not,
please check the USB power supply;
c) Whether the signal strength has become significantly weaker, if yes, please
check the antenna has been screwed on firmly;
B. On-site Inspection: if all above are good, please arrange for an on-site
inspection to check:
a) Whether the Mini Gateway has visible external damage;
b) Whether the antenna is bent or damaged and the node (gateway or sensor
node) is not blocked by new construction, e.g., hoardings;
c) When it is possible, check that the signal strength is normal by using a
spectrum analyzer;
d) Whether any connectors are loose.
Notices :
i. Case One: If any change has been made from the list above, please inspect
the data from the remote server;
ii. Case Two: If all the actions from the list above have not cured the
problem, please contact Wisen. We will be happy to help.

communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
