The purpose of this process is to distinguish problems between antenna and
RF circuit that cause weak RF performance. Besides, wireless test is a previous
analysis of all RF tests. Moreover, engineers utilize wireless test to confirm that
antenna performance is not affected after re-assembling.
The detail steps of process are listed as follows.
a. Put a golden sample of Halley into a shielding box and link to a tester
(Agilent 8960 or R&S CMU9020). Then, record its location and path loss.
b. At the same position that the golden sample was located, put problematic
Halley into the shielding box. After that, wait for Halley registering at the
tester.
c. After attaching to the network, make a phone call.
d. Measure maximum output power and sensitivity. The test requirements
of maximum output power and sensitivity shall not exceed the range listed in
the following table.
e. If any of previous steps (b. ~ d.) is failed, consequently enter next
process, pretest test.
f. If all previous steps (b. ~ d.) are passed, it means that nothing happens.
Therefore, need to clarify customer's complaints and try to understand user's
