This value is for wireless networking between the scanner and the host terminal. The communications range varies with
the equipment used and the operating environment.
Wireless networking requires a stable radio environment. Not all operating environments provide this. In particular, note that
•
Using the scanner in close proximity to other wireless LAN equipment operating in the same frequency band (2.4 GHz)
risks radio interference that can reduce throughput or even entirely block wireless networking.
•
Microwave ovens, industrial heating equipment, high-frequency medical equipment, and other equipment using the 2.4
GHz band can sometimes block wireless networking.
•
Electromagnetic noise from computers, refrigerators, and other home appliances can sometimes block wireless networking.
•
The following environments can sometimes block wireless networking.
- Metal objects or particles in the vicinity
- Metal walls around the area
- Excessive vibration
•
The communications range of 10 m given above is merely a reference value assuming a clear line of sight. Reliable wireless
networking is by no means guaranteed at 10 m for all combinations of equipment used and operating environments. Some
combinations might even work for greater distances, but be sure to confirm that the scanner link operates properly before
introducing the link operation.
NOTE:
To System Designers:
•
Before developing applications, make sure that the intended environment is free of the interference factors above
and thus actually capable of supporting link operation.
•
When introducing the scanner into an environment where equipment using radio waves in the 2.4 GHz band
operates or when introducing such equipment after the introduction of the scanner, be sure to confirm that the
scanner radio link operates properly with all equipment being in operation beforehand.
•
If the environment of the radio communications system is changed after the introduction (e.g., newly installed
household appliances and movement/addition of shelves or objects), then confirm that the radio link operates
properly again before the actual use.
