+ Reach up to 50 meters in lab conditions

+ Recommended distance is 30 meters (Transducer4 to Transducer4 looking straight at each other and other transducers are off)

+ Reach up to 1000 m2 with the Starter Set configurations

+ Coverage for larger territories is similar to cellular networks

+ Absolute: 1–3% of the distance to the beacons

+ Differential precision: ±2 cm

+ 05–45Hz

+ Can be set manually

+ Depends on the distance between the mobile and stationary beacons (shorter distance — higher update rate)

+ Depends on the number of mobile beacons: for example, update rate of 25Hz for 1 mobile beacon will result in update rate of 25Hz/2 for 2 mobile beacons, and 25Hz/3 – for 3 mobile beacons, etc

+ Depends on the radio interface profile (500kbps vs. 38kbps)

+ Slightly depends on the number of stationary beacons—different than for mobile beacons

+ LiPol battery 1000mAh

+ Battery lifetime depends on usage

+ Stationary beacon with 16Hz update rate => up to 72h (tested)

+ Stationary beacon with 1Hz update rate => ~72h*16 => 1 month

+ Mobile beacon with 8Hz update rate – 12h (tested)

+ microUSB – recommended for permanent use

+ 59 grams (including battery 1000mAh and housing and antenna 50mm)

+ 27 grams (bare board w/o battery)

+ 55x55x33 mm (with 50mm antenna: 55x55x65mm)
