Improving Radio Coverage
Wireless connectivity between radio-equipped portable terminals and host
computers is unique and maintaining this wireless connectivity over a wide
area is fundamental to the usefulness of the network. As such, the scope and
reliability of radio coverage is a primary concern. Therefore, one of the most
important features of the wireless network is the degree of radio coverage
provided. Coverage is influenced by terrain, buildings or a crowded room.
There are many things that can be done to improve coverage depending on
location.
In any location
1. Performance can vary significantly at different times of the day.
2. Weather can affect performance.
On the street
1. Try all sides of a building to see which side provides the strongest radio
signal.
2. Move from under trees. Pine needles absorb radio signals more than
leaves.
3. Move away from overhead electrical wires.
4. Radio signals reflect off other buildings. Even in the signal shadow, the
signal could be reflected back by another building.
5. Try not to hold the unit. If possible, place it in vehicle, on a cabinet or
desk.
6. If holding the unit, turn the unit in 90-degree increments to avoid
shielding it with your body.
7. The signal is 1 - 2 feet across; therefore, moving several feet in any
direction may give different results.
