Thanks Alex and Fanny. The topic is very ineresting for me as a FAE for wireless product. HOwever, this audio archive is wrong. It stops in half way about 17 minutes only. Can you help to fix it?
BY THE WAY MY INTEREST IS TO APLY WIRELESS CONTROL INTO NUCLEAR GLOVEBOX TECHNOLOGY TO REDUCE THE NUMBER OF PENETRATIONS AND THEIR INHERENT LEAKAGE THROUGH THE GLOVEBOX WALLS.
ANSWER: FOR TOMORROW, FOR OUR WRAP-UP CLASS IN THIS TRACK, WHAT ISSUES IF ANY WOULD YOU LIKE EXPLORED OR DO YOU STILL HAVE QUESTIONS IN?
I'd like to see some charts that include the ranges of various means of wireless standards.Do I choose Wifi, ZigBee, Bluetooth, etc.Some examples of what equipment that would be needed for developing would be good.Chart forms would be nice for these items.I know it would be large/extensive, but so is the wireless field.
Also, an acronym listing would be nice.It would have been nice to have such a listing on day one of this week.
ANSWER: ARE YOU INTERESTED IN THE INTERNET OF THINGS? WILL YOU SUPPORT IT AND WHERE DO YOU SEE THE MARKET OPPORTUNITY?
Most definitely.Nearly everything is being connected via the Internet.Designing without knowing how to connect via the Internet will be the death of a design career.I realize that not everything will have connectivity, but not having the knowledge will lead to certain death of an otherwise career.
ANSWER: WHAT PROTOCOLS DO YOU NEED TO KNOW MORE ABOUT?
I don't think I would restrict my interests on any single specific protocol, but rather on a comparison of protocols.What protocols are used where and why they are chosen for their applications.What the pros and cons are for each that support their choice for a given application.
PLEASE ANSWER: WHAT ABOUT THE SMART GRID ARE YOU INTERESTED IN LEARNING? ALSO, WHERE ALONG THE SMART GRID IS YOUR MAIN POINT OF ENGAGEMENT, from power plant to home.
I'd be more interested in the development of the equipment used within the infrastructure of the smart grid.
DO YOU SUPPLY UTILITIES OR COMPANIES WORKING ON SMART GRID? WOULD YOU LIKE TO AND WHAT WOULD IT BE?
I do not work on supplying the utilities or companies working on the smart grid, but I would enjoy working on the development of the various tools used by the utilities for the smart grid.Any of the HW/SW/FW would be a pleasant challenge.
Sorry I missed today.It couldn't be helped.I'm not sure if in addition to using the .ppt and listening to the presentation if I should be posting.I don't know if my posts will be archived and if anyone will read the posts, but I'll proceed as though I were here at the normal time.
Thanks Alex, Fanny, and all! Although I learn RF and have used in some of my projects, this week program humbled me, with so much to know. I am glad that so far I have kept myself busy with wired infrastructure and software. There is so much out there to learn. :o)
Fanny, which standards are being considered for vehicle-to-vehicle networking (such as along a highway). And similarly, what's being looked at for vehicle (cars, etc) trackig along streets and highways? Sorry if this is a double post.
Nice Presentation today. Is there anything that you can share about how the move to PTC (Positive Train Control) will fit in with the Smart Grid when it becomes fully deployed?
reducing the clock rate refers to reducing the sampling rate - the rate of actually generating the samples so narrower channels require no extra logic in the chipset
Thanks Fanny for the great introductory information. Today, and the past few days have given me a good start to understanding and preparing for the variety of wireless systems.
It also may have revieved an interest in RF again.
•IBM's Cognossoftware and other analytics products determine power consumed by appliances (e.g. air conditioners) and analyze power consumption trends among households.
@FANNY: On Slide 6, OFDM Considerations: "Narrow band operation is achieved by lowering clock speed (in the DSP, I think you said)": Are you talking about reducing both the sampling rate (I assume you are sampling the carrier baseband?), and the DSP processing rate, i.e. running the same processing code at a slower rate to match the sampling rate? Seems like there are some unstated assumptions about the processing mechanism. Thanks for a great course.
Question for Fanny for tomorrow: Interest in techniques and low-cost test equipment to check for radio interference that could occur in 802.11 or other wireless standards. If Wi-Fi network is experiencing interference or impairment, how can we capture, observe, quantify this?
@JM Ashcraft: 802.15.4g was appproved by IEEE on Mar 29th. 802.15.4k and 802.15.4m are WPANs currently at task group stage (http://www.ieee802.org/15/). 802.15.11ah and 11.ag sub-GHz WLAN
Question for tomorrow: wireless standards for handset (mobile phone) compatibility? aside from the obvious wifi and bluetooth, any other standards poised for wide deployment (ex, ANT)?
some public safety 911 centers had a problem tracking or determining the caller's location who are moving and using their cell phones, as they upgrade their equipment will this solve this problem?
It appears to me that the "heart" of the smartgrid from the perspective of an individual or business is their power meter. According to the smartgrid concept, the power company would be changing power rates dynamically and providing that information via the meter base for user-side devices to behave accordingly for. Is that true? Is there more to it? If so, the two critical pieces of information for design are how to get that information from the meter, and how to avoid colliding with your neighbor's information (sharing airspace as well as keeping all the devices in the correct network). Where do I find information about those two items.
ACHRONYM DICTIONARY: I begining to look at developing an achronym dictionary in Telecom and IT. Any one intereste in contributing is welcome to send e-mail to luizcosta@sbcglobal.net
think i remember seeing several years ago a refrigerator that would allow you to either scan a bar or enter information about its contents. you would then be able to generator a shopping list.
QoS: This is the biggest challenge, for the industry has abandoned solid telecom ATM (asynchronous transfer mode) technology, and embraced shared ethernet. What is your take on that?
I don't trust having all devices in my home/work/vehicle to be in constant communication and control to the outside environment. Too many ways for things to go wrong.
Sub GHz is going to be a better medium than 2.4 GHz for FAN / AMI and probably has advantages for HAN. Look at 802.15.4g and 802.15.4k for utility endpoint FAN / AMI.
Slide #3 EU ISM band is 863 - 870 MHz (Annex 1g of ERC 70-03) PRC ISM Bands 470 - 510 MHz, 702 - 787 MHz (15.4g targets 779 - 787 MHz of this upper band)

QUESTION: Chip level of off the shelve choices mayl depend on the scale of deployment. If I have 5 years to deploy a smart grid application, would it be economical to go custom design for 55,000 homes?
Last discussion about Smart Grid communication net was halted with security up to HV transmission system. Any new trends in this matter / security barriers?
Yes, would like to supply irrigation water level flow meters to irrigation company via periodic measuring devices. Long distances are involved with low accessibliity to power and maintenance.
Long distance people --- (>2miles), how are you planning on doing that? WRT regulations and power consumption. Do some of those standards account for up to 25 mile transmissions?
I am a graduate student. My interest in radio communications is for robotics communications and also home area networking. Currently no large area networks planned.

With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
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.
