Antenna Considerations

For models with internal antenna the characteristics of the antenna should be considered
when choosing the placement and orientation of the Bridge II Serial.
Required Distance Between Devices
For optimal reception, wireless devices require a zone between them clear of objects that
could otherwise obstruct or reflect the signal. To avoid signal interference, a minimum
distance of 50 cm between the devices should be observed.

3.5. When to Use Bluetooth or WLAN
Use Bluetooth when:
• The wireless link has an Anybus Wireless Bolt or Anybus Wireless Bridge II at both ends.
• An interruption-free connection is more important than data throughput speed.
• Interference robustness is important, e.g. in an industrial environment.
Use WLAN when:
• Connecting to other types of wireless devices or a WLAN infrastructure.
• High data throughput speed is more important than connection reliability.
• Large file transfers are expected.
• WLAN channel frequency planning is possible.
