another useful hook would be an ability of the device to scann all the channels and report how much activity is seen on all the available channels. this can help select the best channel of operation, for example.
Academic labs (or any new labs coming online) will need to be certified by CTIA to do certificaiton testing. Internationally, you also need GCF and PTCRB certificaiton of the certification labs.
if you can include hooks into your wireless driver so that the user can request RSSI, BSSID (association info) and some rudimentary statistics (e.g. RX and TX frames) that could be enormously helpful.
Based on your experience, are there any debug hooks you have found particularly usefull for replicating and debugging problems from the field/customers ?
please see some white papers and test reports on our website at http://www.octoscope.com/English/Resources/Whitepapers.html. i cannot think of a book off the top of my head, but there are several worth reading.
more is not always better when it comes to the size of the team, but you want to have enough people to create a good automation framework. I would say 3-5 people total, give or take. it really depends on the complexity of the software on top of the radio, too.
we need some information on the RF environment in the field and then we need to try and reproduce this environment in the lab and try to replicate the failures. that's the hard part. if you can reproduce the failures, typically fixing it is the easy part.
@FANNY: "typical problems in the field: no connection, low throughput, low quality of voice or other real-time services, roaming drops sesssion, etc."
And then when this cases go back to the lab, what type of conclusions heve been reached as far as the limitations of the lab tests? In other words what have been some learned lessons?
Fanny, I liked your comment that QA tests are developed in parallel with the product. Production and repair tests are usually an after thought. Sometimes carefully considered tests can determine parts of the product design for manufacturing and repair.
@ANN: Can you ask Fanny to tell us about typical problems that happen in which field anomalies happen even though the device(s) passed all lab condition tests?
I am involved in mobile Networks, but this measurements is made by equipment provider before sale, i was involved in this kind of measurement in Spain long time ago
If you haven't told us yet, please let us know 1) if you're involved in QA testing, and if yes, what radio technology and applications are you testing? 2) what do you use as an automation framework for your QA testing and what is the scripting language that you use: PERL, TCL, Python, or LabVIEW, for example?, 3) do you use screen rooms for QA testing?, 4) does your wireless system involve mobility and is mobility an important part of your test?

1 - yes for wifi and bluetooth, 2- Labview generally

Using almost 200 light-emitting diodes in the front and back of the new 2014 CTS, Cadillac designers are showing how LEDs can change the character of a vehicle.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
