Factors Reducing Wireless Range
• Wireless range is affected when metal obstacles are in the
line of transmission.
• A solid sheet of metal and some rebar reinforced concrete
present the greatest obstacles.
• Try to note the following objects and avoid them in the line of
transmission:
- Hollow lightweight walls filled with insulating metal foil
- Office equipment and furniture such as book shelves, file cabinets,
metal partitions, computer racks
- Metal reinforced concrete walls, pillars and columns
- Glass walls with metal coating
- Plumbing and electrical risers
- Elevator shafts and stairwells
- Mechanical and electrical equipment rooms
The bigger the metal obstacles in the transmission path, the shorter the wireless range.
