The tent enclosure should be really waterproof to allow the tents to be washed in the restaurant. The tent beacon has an accelerometer to extend battery life by trigger on accelerometer event. The idea is to redesign the electronics to use a larger battery.

This is because the signal to noise ratio will be lower.įull disclosure: I am Chief Engineer for Radius Networks.User Manual RadBeacon Locator Tent Model: RBT-003 Bluetooth Smart 5.0 proximity beacon powered by 1 CR2477 Lithium battery with tent form factor for extended battery life and a waterproof enclosure. You should note, however, that by lowering the transmitter power, you will also increase the amount of variation on your distance estimates. The apps have a slider control to increase and decrease the transmitter power.

Using Radius Networks' RadBeacon USB and RadBeacon Tag models, you can adjust the transmitter power using the free RadBeacon configuration app for iOS and OSX. If it helps your use case, you can also lower the beacon transmitter power so that devices only detect the beacon when they are relatively close. For this reason, you must design your app so such variation is acceptable. However, the best you can hope to do is reduce the variation as much as possible. When possible, place your beacons where there is a clear line of sight to the receiving devices. The stronger the signal, the lower the noise level will be (relatively speaking) from source 1 above. Use as high of a transmitter power setting on your beacon as possible. More transmissions mean more statistical samples of the signal level, which when averaged together help mitigate errors from sources 1 and 2 above. Use a beacon that transmits as frequently as possible, preferably at 10Hz or more. There are a few things you can do to minimize the error: This means that when you rotate your phone or the beacon, you will see a slightly different signal level.

The bluetooth radio waves reflect off of some objects and are absorbed by others, making the actual signal strength change at different positions the same distance away, and when other objects in the vicinity move around.There is error on the analog to digital converter inside the bluetooth radio, which also causes individual signal strength measurements to vary.There is always background radio noise (like the static on an old AM radio) which causes individual signal strength measurements to vary.This technique is imperfect, and there are several reasons for fluctuation: If the signal is a little bit weaker than -56dBm, such as -65dBm, the formula might estimate that the distance is 2.5 meters. A formula inside the mobile phone then tries to make a guess of how far it is away based on the signal level at any given time. The beacon transmits a reference value of its expected signal strength at 1 meter, saying in effect "If you are one meter away, you should see my signal level as -56 dBm". A stronger signal means that the beacon is closer, where a weaker signal means the beacon is further away. Beacon distance estimating works by starting with a measurement of the radio signal strength using the bluetooth radio on the mobile device. You will always see fluctuation on beacon distance estimates, so you have to set your expectations appropriately.
