There
are numerous manufacturers of R/F mobile terminals. As to be
expected, some are better than others. Generally speaking the
more expensive terminals are in fact a better investment. When
evaluating wireless terminals several factors should be considered:
Durability - This is perhaps the single most important
consideration. Terminals that appear to be functionally
equivalent, may in fact be quite different. In a
warehousing/manufacturing environment the terminals may be subjected
to a very harsh environment. Such things as water, humidity,
dust, heat, cold, shock, and impact are a few of the common causes of
equipment failure.
Battery Life - The size and type of battery is very important
to the successful use of a handheld terminal (vehicle mount devices
can be powered from the vehicle battery). Battery life varies
greatly based on the type of battery, radio, scanner, and amount of
scanning performed.
Keyboard Layout - There are a variety of keyboards available
for the various terminals. It is important be have a keyboard
that suites the type of R/F transactions be performed.
Scanner Specifications - Having the correct scanner is critical
to the acceptance and success of the initiative. Not all
scanners are the same, and if you have the wrong one your workers will
quickly become frustrated and perhaps be unable to use the equipment.
Support
- As good as the current generation of R/F terminals is, the fact is
they will still fail on occasion. In addition to terminal
failure there is also the potential for network disruptions and/or
blind spots in the R/F coverage. Very important to be working
with an integrator and terminal manufacturer who will be there when
there is a problem.
Cost - Generally speaking the more expensive the terminal the
better it is. While a "high-end" terminal may not be in the
budget, the total cost-of-ownership may be quite different when repair
cost and down-time are considered.
There are many other factors to consider, such as display size and
type, touch screen, color or monochrome, etc. For this reason it
is important to work with an integrator who will help you avoid the
pitfalls in hardware selection. |
