Regulatory compliances, Yes

missed it but its a good presentation

 

Iron

no qa testing, no cleanrooms

 

Iron

no automaintion testing.  bash.

Iron

I am not involved in qa testing. 

Iron

good QA testing overview...

Iron

I sometimes do QA testing...

Iron

Thank you for your time Fanny.

Iron

@Ann - re. mobility... YES, mobility is one of the most important aspects

Iron

@Ann - not for the particular type of testing I was involved in... mostly just cabled RF

Iron

@Ann - mostly in-house automation tools, for scripting - Perl, shell scripts, C

Iron

@Ann - used to be deeply involved in QA testing for CDMA, EVDO

Iron

Great to have access to the recorded sessions.

Iron

Missed the live lecture due to travel...

Iron

SATELLITE Communications Receivers

Iron

Thanks Fanny 

Some Good Comments

yes we do regulatory complice testing just not on wireless yet

Yes it does involve some mobility

no I am not involved in QA testing

Looking forward to some more good info on wireless

Hello picking up another one a few days late

Seems to me, that this is yesterday's lecture...

Iron

I would like to see more courses int he future.

Iron

Keep up the good work.

Iron

Thanks for sharing knowledge. Very interesting Lecture

Iron

Thanks to Fanny and all.

Iron

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.

Blogger

Thanks Fanny and Ann, see all next time.

Iron

Thanks for  the Lecture, Fanny, it was veey interesting,  I ´ll see you tomorrow

Iron

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.

Blogger

many thanks for the great presentation Fanny... see you tomorrow

Iron

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.

Blogger

Are academic labs able to do the certification as well?

Iron

thanks

Based on your experience, are there any debug hooks you have found particularly usefull for replicating and debugging problems from the field/customers ?

Iron

labs for wirless cert include TUV, 7layers, CETECOM, AT4 and others.  they may also do pre-certification.

Blogger

@FANNY: Thank you for your wisdom!

Iron

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.

Blogger

@Fanny, you got any suggestions where I can find a list of places where I can do pre-certification testing?

Iron

@FANNY Are these FCC test reports available?

Iron

Is there any reading material your particulary recommend, e.g. a book or a white paper ?

Iron

we have examined the FCC reports on Apple iPhone and these were interesting.  I don't know how they tested in their lab.

Blogger

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.

Blogger

@FANNY: Very interested in knowing about Apple plaaning tests and field test requirements. Any info you can share?

Iron

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.

Blogger

yes - planning ahead brings important benefits - faster time to market and better products

Blogger

Thanks, what size team is that assuming ?

 

Iron

@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?

Iron

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.

Iron

a typical radio test cycle should take 1-2 months

Blogger

@FANNY: Sorry I cut and paste "ANN" from the previous time the question was posed.

Iron

From your experience, once a new design is in the prototyping, how long does it take fully test it and start production ?

Iron

typical problems in the field:  no connection, low throughput, low quality of voice or other real-time services, roaming drops sesssion, etc.

Blogger

@ANN: Can you tell us about typical problems that happen  in the field even though the device(s) passed all lab condition tests?

Iron

Thank You, good session

Iron

Lecture very informative and interesting.

Iron

Thank you, nice presentation..looking forward for tomorrow session!

Thank you for another interesting presentation

Iron

Thanks Fanny and Ann. This session provided many good things to consider when designing tests for QA, not necessarily just in wreless testing.

Iron

Interesting presentation, thank you.

Iron

Thank You for a very interesting lecture!

Iron

thanks Ann ... see you tomorrow

Iron

Thank you, excellent presentation!

great presentation Fanny!

Thank you Fanny - great information, well presented.

related to  Power or other emission  we have a  local standard for each service in my Country, based in UIT, FCC, ETSI standards

Iron

Very informative presentation. I learned a great deal! See you tomorrow.

Iron

Thank you Fanny, need to leave.

Iron

A reminder, if you've got additional questions for Fanny, she will answer them in the second part of the show on the comments page.

Blogger

here we install  equipement  and the Provider(Ericsson , Huawei, ALU) has to acomplish with  GSm association or 3GPP   Reggulation bodies

Iron

@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?

Iron

FCC and UL pre compliance testing

Yes, new products need to conform to regulations.

Iron

No, only precompliance testing of EFT, ESD, Surge, Conducted Immunity, Conducted Emission, radiated emission, ...

Iron

The latest question is are you involved with regulatory compliance testing?

Blogger

Yes on regulatory compliance testings

Iron

Yes, test and certify to standards, via 3rd party cert lab.

Iron

yes, our products must meet many regulations for electrical safety in hazardous locations and FCC

Iron

Yes, CSA and CE regulatory compliance testing.

Iron

@Ann: not involved with regulatory testing.

Iron

Not at this time, but have been in previous positions.

Iron

I'm not involved in regulatory compliance testing

right now I am not involved to this kind of testing.

Iron

@Ann - no regulatory compliance testing involvement

Iron

Yes, involved with CE approvals, but use 3rd party for the actual testing

no, but I am a regulator...so I am interested in the topic

No on reg. compl. testing

Iron

Yes on regulatory compliance testing

Iron

I'm missing graphics on slide 17

Iron

What is a typical anechoic chamber size? and what kind of material they are made of?

Iron

For LTE,   I think so

Iron

which slide are we at now?

Iron

no mobility currently.

Iron

Hi All..Sorry I am late.

Iron

Most recent wireless testing was between two stationary medical devices, neither was mobile.

Iron

Testing in real time.

Iron

what is anechoic chamber?

Iron

No mobility currently, but we design our test devices to support mobility should it be requested.

Iron

no will be fixed locations.

Iron

Yes we require mobility and and need testing.

 

 

Iron

short range Bluetooth only, no mobility involved.

Iron

@octoScope: interesting to see that Azimuth also scripts with Tcl. Very versatile platform.

Iron

Hi all, Sorry i'm late.

Iron

Mobility is important

Iron

Mobility - yes, but not always tested

Iron

The latest question is does your wireless system involve mobility and is mobility an important part of your test?

Blogger
