XBee antenna installation guide

Some notes regarding the range of the XBee radios:

The MR Starter Kit lets you send corrections up to 1200m, in perfect conditions. In practice, this means with always line of sight:

  • 250m in urban environment.
  • 600m in rural environment.
  • 1200m in rural environment with perfect installation.

The LR Starter Kit lets you send corrections up to 10km, in perfect conditions. In practice, this means with always line of sight:

  • 2.5km in urban environment.
  • 5km in rural environment.
  • 10km in rural environment with perfect installation. And up to 14km if you use a high gain antenna.

The XLR radios (with 500mW configuration) let you send corrections up to 50km, in perfect conditions. In practice, this means with always line of sight:

  • 5km in urban environment.
  • 20km in rural environment.
  • 50km in rural environment with perfect installation. And up to 80km if you use a high gain antenna. But RTK corrections are not valid so far 🙂

There are 2 very good application notes done by the XBee manufacturer Digi, explaining what does “perfect installation” mean:

Note Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.
