HALT test, Power up test,benchmark

Yo Rob Spiegel, that name Mlinarsky, it's easily just leave out the capital "M"

then it is lin-AR-ski , OK.

Iron

Thank you. Hear you tomorrow. Have a great day.

Iron

Thanks, Fanny, for a great program. Thanks everyone for attending. See you again at 2:00 Eastern tomorrow.

Blogger

Sorry - not off the top of my head, but smallnetbuilder.com may have some security test results published.

Blogger

Do you have any recommended websites that address the topic of methods of "Data Security Testing" for Wireless Devices  ?  

 

 

Iron

As mentioned, what you measure for isolation depends on how you measure it and most vendors don't include the data lines in their isolation specs.  We do.

Blogger

isolation is guaranteed to be better than 80 dB with data lines going through filters, which is the worst case.

 

Blogger

Feed through caps work well for power lines, but you need fairly sophisticated feed through filters for gig Ethernet and USB and HDMI

Blogger

Thanks. On the transmission loss, I was asking about the isolation from outside interferring signals, that would propagate through the walls.

Iron

Are the filtered connections coming into the box using feed-through capacitors, or something else?

Iron

Return loss is better than 20dB from 1 GHz to 6 GHz and better than 15 dB down to 700 MHz.  The loss is typically associated with antennas.  The signal is fed in through barrel connectors, so no loss there.  Test frequencies supported are from 700 MHz to 6 GHz.

Blogger

Thank you for today.  My two questions are: what is the average transmission loss of your test chamber from the outside of the box to the inside at a typical DUT frequency. And secondly, what is the ballpark worst case return loss of the interior walls at a typical DUT frequency?

Iron

802.11ac will dominate in the future in iPAD and other devices.  Chip vendors will drive the prices down with volumes.

Blogger

Thanks, I will look at your MPE product.

Iron

Will future IPADS use 802.11ac so that it might be possible to stream high definition video ( over wireless) to an IPAD ?

Iron

The MPE is a broadband device and works from near DC up to 6 GHz and beyond.

Blogger

for SISO you can use programmable attenuators to measure range and a base station emulator and some VSA/VSG instrumentation to measure TX and RX integrity.  you can also use the MPE in a SISO mode.

Blogger

So this MPE, I would want to use it simulate the OTA environment to test and understand the behavior of a 2G/3G cellular device. Is it suitable for that type of work? At this point we would not be using it for studying MIMO, and not for 802.11 (yet).

Iron

infotainment systems tend to use wi-fi or bluetooth.

Blogger

For aviation cockpits, my understanding is that custom wireless technology has been used but that the industry is looking more at commercial technologies like Wi-Fi now.

Blogger

a programmable channel emulator for 802.11ac today costs on the order of $300-400k.  it's an expensive beast.  Our MPE is a tenth that cost.

Blogger

Do you know what wireless standards will be used for commercial aviation cockpits and infotainment systems ?

 

 

Iron

We sell a 4x4 MIMO multipath emulator (MPE).  This is a low-cost fader that emulates a typical home environment.

Blogger

you can find Wi-Fi test data on www.smallnetbuilder.com

 

Blogger

We are currently testing a 3G/2G device. The connectivity is impaired by low signal level that is further reduced by fades. Does octoscope sell a channel emulator? If so, what is the approx cost? This is not a MIMO system.

Iron

you can perform EMC testing in an octoBox but you would need to calibrate the absolute levels to a certified lab

Blogger

I was hoping to find existing data (like you shared regarding Verizon LTE in the Boston suburbs).  Thanks for the presentation

Iron

octoBox configured with typical filters and accessories typically sells for around $9.5k

Blogger

You can use controlled OTA test chambers to test more than one device in the same airlink

Blogger

What is the approx cost of a basic octobox, say one that is roughly the size of a case of beer or window air conditioner?

Iron

?? Fanny I wonder if also perfom EMC testing at octoScope ?

Iron

Do you test (or know of testing) with more than one device at a time to see how well bandwidth is shared?  It would be useful to see how the different technologies (WiFi, LTE, ...) compare.

Iron

thank you Fanny !

I am talking this up other Avionics Engineers

What do they do at MKS/ENI?

Iron

We're now on slide 26.

Blogger

Is this a testbed for design characterization/validation?  Production?

Iron

There is an RF test chamber with an absorptive end (anechoic?) at MKS/ENI Rochester, NY.

We're now on slide 25.

Blogger

We do not have an anechoic chamber here.

Iron

We're now on sldie 24.

Blogger

Have not done this test.

Iron

We've used Faraday cages during test and validation

Iron

Haven't do testing on radio layer.

Iron

Don't have anything like this.

Iron

Yes, we have a testbed similar to the one described

We do not have a formal test environment like this. I wouold like to have one.

Iron

Don't have in-house test bed.

Iron

Yes, I've configured this kind of testbed

Iron

 Fanny's question:

Do you use a testbed that is focused on radio layer test?
