Thanks  Fanny for Presentations.

Iron

Wow  Excellent Presentation

Iron

Thank you fanny and Ann, for the very well done presentation.

Iron

Thank you for presenting this seminar.

Thank you Digikey for archiving and having these programs.

Iron

Thank you Fanny, it was great seminar!

Thank you for this whole series

Iron

Got time to finsh this one.

 

Iron

@Ann - yes, used to do antenna selection and radio coverage prediction (BTW, it's a job of a systems engineer... and has nothing to do with testing. if you select antennas at the time of deployment, it's too late - something is really wrong in your process)

Iron

@Ann - licensed bands

Iron

Slide 3 generalizes too much - many steps are outside of the deployment _test_ process (they are related to the system design)

Iron

@Ann - used to be involved in wireless deployment, optimization, ATPs, etc... for CDMA 1X

Iron

Great to have access to the recorded sessions!

Iron

Missed the live lecture due to travel...

Iron

better late than never

Iron

Thanks again. Good informative session.

Iron

Thanks a lot. All these five sessions were very informative. They made me realize how little I know.
 I may, now, understand wireless test methods and techniques...

Iron

good weekend, and thanks

Iron

thank you all for joining!  I appreciate the warm feedback.  I hope you all have a nice weekend.

Blogger

chipset vendors will typically focus on R&D and production test.  however, they are also responsible for roaming funcitonality and other system related functions that would be part of QA test.

Blogger

So for the modem chip vendor , which of the test categories you outlines before (R&D/QA/Production/Deployment) are they expected to perform ?

Iron

utually it's either the service provider or IT departiment that manages the deployment and deployment test

Blogger

@blogger: Yes, the AES encryption are present for both.

 

So who gets invloved in the deployment tests. Is it the carrier that does all the deployment testing, or do they also bring in the device (cellphone) maker and/or the modem chip vendor too ?

Iron

encryption is byte by byte encoding while authentication only happens at the beginning of the session

Blogger

encryption is AES for both WPA and WAP, I believe

Blogger

@ricardo.medeiros: different security wrappers (encryption schemes) will demand different overyead. WPA is a more complex algorithm, and thus will have implications on packat loss. WE{ authentication is retransmitted "in the clear" while WPA hides it. So, I would say, WAP's overhead is greater.

Iron

So for LTE,  if you want to deply your radio internationally, is there a small sweet spot of frequencies that would cover every where, our would you have to create a different flavour of the hardware (FEM) to cover the different areas (e.g one for north america, one for asia, one for africa, ...) ?

 

Iron

TD LTE will be deployed in Asia and expected to be in the 2-3 GHz range

Blogger

LTE spectrum worldwide ranges from 700 MHz to about 3 GHz.  I don't know off the top of my head where the international deployements are in frequency.

Blogger

It's hard to explain signal level difference between WEP and WPA2 since encryption is the same for both and data rates should have been the same... could be some anomaly in the equipment?

Blogger

Thanks much Fanny for your wonderful coverage of wireless testing.  I'm very happy to have attended this course.  Hope you get some trinkets for your effort :-).

How about the frequencies world wide ? asia, europe, africa  ...  ?

 

Iron

Dear Fanny, I've experienced different signal quality in some differents point far from an AP, just changing the security function from WPA2 to WEP.
With WEP I got much better signal quality (level) then with WPA2. What is the explaination for that. Thanks. Ricardo.

today 700 MHz LTE deployments are most common - both Verizon and ATT deployed LTE at 700 MHz

Blogger

Thanks a lot for the very valuable and interesting lecture series.

 

Iron

Thanks alot fanny for sharing your considerabke knowledge with us.

Whqat are the most common frequencies deployed for LTE and for 802.11ac ?

Iron

Thank  a loy for your lectures,

Iron

I side with Mr. E. Well said.

Iron

Thank yo for this interesting series

Iron

Thank you so much fanny. Very valueable data.

Iron

@octoScope: another fantastic and informative week. Thank you so much, not only for your thorough preparation, deep subject knowledge, and in-the-trenches practical insights, but especially for your willingness to share it all so freely with this audience. Great job! Wow!

Iron

Thanks for a great week - I'm encouraging some of our people to view the archives to get oriented on RF testing.

Thank you for a most invormative series Fanny.

Have a well deserved restfull weekend if there is such a thing

Iron

Thanks Fanny and Ann. See all next time.

Iron

Fanny,

Thanks for an excellent week of lectures.

LOTS OF GREAT INFO FOR DESIGN AND TROUBLE-SHOOTING PROBLEMS. THANKS FANNY.

Thanks for everything

Ann and Fanny, this has been an invaluable week of information.  Thanks to both!

Gold

thank you Ann and DigiKey...look forward to next session

Iron

Thank you Fanny, Ann and Digikey for excellent week of presentations. Very informative and a lot to digest. Thanks again.

Iron

Thank you Fanny for providing an interesting and usefull week. The test requirements and techniques look like they apply to applications other than wireless.

Iron

Thank you Fanny - a great week of presentations full of valuable information

Iron

Thank you for this week of informative presentation!

Iron

Thanks Fanny,

a great week of discussion on wireless

Thank you for a good series.

hello Fanny and Ann, and a shout out for all

Iron

Ann - Each day this week your audio has been very faint while Fanny's is loud and clear.  I've seen several other attendees note the same - so I'm not the only one with a problem.  Is there anything you can do on your end to increase your volume?

Iron

Good morning Fanny, Ann and all. Happy Friday 13.
