When dealing with wireless sensor networks, there are a lot of factors that affect the quality and reliability of transmission signals between your sensors and the gateway (receiver). We have compiled a list of useful tips to improve your wireless sensor network.
Position your Wireless Gateway in a central location
Whenever possible, position your wireless gateway in a central location within your facility or home. If the gateway is against an outside wall, the signal will be weak on the opposite side of your building.
Position your Wireless Gateway off the floor and away from walls or metal objects.
Floors, walls and metal structures such as heating ducts and file cabinets, interfere with your sensor network’s wireless signals. By avoiding these structural “Signal Killers” when placing your wireless gateway and sensors, you can ensure optimal performance of your network.
Use a Wireless Repeater.
Repeaters allow you to extend the coverage area of your wireless sensor network by repeating the signals between your wireless sensors and the wireless gateway. Place a Monnit Wireless Repeater / Range Extender halfway between your wireless sensors and the wireless gateway, and you will get an immediate boost in your wireless signal strength. The repeater will also act as a central access point for all of the sensors that are within it’s range.
Reduce wireless interference.
If you have cordless phones or other wireless electronics in your facility or home, your gateway might not be able to “hear” your sensors over the noise from the other wireless devices. To quiet the noise, avoid wireless electronics that use the 900MHz frequency. Instead, look for cordless phones that use the 5.8GHz or 2.4GHz frequencies.
