This chapter provides information about the RIM 902M that will be useful in
determining the physical positioning of the radio modem within an application.
Environmental properties and testing, physical properties, mounting methods,
and connector information are presented.
Environmental properties
During environmental testing, RIM takes samples of its radio modems and
subjects them to a variety of harsh conditions. We measure over a hundred
digital RF calibration parameters, once before and once after each test. The
difference between these measurements precisely reveal any performance
degradation. Each unit in the sample is also inspected visually after testing.
This experience allows us to fine-tune our design and manufacturing process.
Environmental testing ensures that our products are able to withstand both
typical and extreme real-world conditions in which they will be used. RIM does
not sell units that have been subject to environmental testing.
