Bus connection

Radio frequency 315 MHz (Asia), 868 MHz (EU countries

and China), 902 MHz (USA and Canada)

and 928 MHz (Japan)

Ranges

… dependent on the

nature of the building

Range reduction due to wall materials

against free-field propagation (300 m):

• Wood, plaster, uncoated glass,

without metal 0 – 10%

• Brick, pressed wood 5 – 35%

• Concrete with iron reinforcement

10 – 90%
