What is the range of a chirp?


The range of transmission varies depending on several factors. These include the volume of the transmitting device the acoustic environment and sensitivity of the listening device. Typically the range extends from a few centimetres to a few metres.

Mobile devices are usually easily capable of around ~10m at full volume, but this varies by device and acoustic conditions.

With larger loudspeakers, Chirp can broadcast data over 10s or a few hundred meters.

    would it be reasonable to expect that in an environment like a grocery checkout lane that chirp could broadcast reliably from say an iPhone within a box of 2m? 1m? 10m?, 10cm?  i think i'd be looking to move about 800 bytes of data at the most.
