Testing of Win CE would seem to indicate that you are looking at testing the UI of a wireless device. TestQuest has a tool that works for that situation. The second half "test ... and wireless protocol", seems to indicate that you are actually performing RF testing. In that case, you would have to look at some of the network emulators dependent on your protocol. Spirent, Racal, Aeroflex, Agilent, etc. would be places to start for a wireless protocol tester.
I think your question may need a little context. Are you perhaps talking about testing a wireless network connected Win CE based laptop? In any case you need to explain what devices you try to use so that we can at least take a stab at giving you an answer.
