Thank you for the informative presentation

Iron

Thank you Fanny for informative lecture

Loging on a day late and then some. Just too busy yesterday. Making up for yesterday and today.

   please correct as I would like to know if a television transmitter can be repurpuse for cellular,

Iron

Is there a way to repurpuse a television translated to cellular use, ie with cards etc

Iron

How would you advise an older engineer to search for a new career in the LTE/WiFi Space?

Iron

I am not, only low level and local networks!

Iron

Thank you, Hear you again tomorrow. have a great day.

Iron

Thanks Fanny for a great lecture. Chat time is up, but you can join Fanny again during tomorrow's lecture. It begins at 2:00 pm Eastern.

Blogger

Thanks Franny, et.tal.

Iron

Question: If the trend is to smaller and smaller cells to serve people more closely to their location, do we expect radiated power from the nano/pico/femto cells, and from subscriber devices, to be going down as time goes on?

Iron

Want to stream video from roaming handheld cameras at an event with lots of users, eg convention, concert, etc. that attendees can then view on their devices via WiFi.  Possible to ensure video from cameras gets through to the servers?  Cameras don't have to be WiFi but battery life is a concern.

Iron

Thank you all!  I hope to 'see' you tomorrow.

Blogger

optical links can be used for base station to core network links.  

Blogger

RMRSS asks:

Are there any problems with optical tie ins and higher frequencies?

Blogger

i remember 300 baud too :)

Blogger

for LTE standards, check www.3gpp.com or our website www.octoscope.com under 'publications'.

Blogger

Fanny:

A 19.2K MODEM is a new-fangled thing -- having worked on 1200 and 2400BAUD machines...

And that's all I'm admitting to...

Iron

2G and 3G latencies are a big unkown and vary from operator to operator network.  octoScope measured around 100 ms latency on the Verizon LTE network, which is very impressive for a wide area network.

Blogger

Wonohkim asks:

Where can I get detail information on who (such as AT&T, Verizon, ...) uses what frequency? I heard that FCC web site contains info but don't know where. Does anyone know?

Blogger

??Where can we get some additional information on LTE standards?

Iron

For a single-AP network, forwardng latencies should be in single or double-digit ms range

Blogger

Thanks Rob, Fanny answered that.

Iron

CPU asks:

Question, when comparing 2G to 3G, please discuss the real-world latency. For example, sending small volumes of data, do you expect the latency from point to point to be much smaller on 3G? Say a computer with cell modem connecting to another computer on internet - the time for the packets to arrive.

Blogger

what latency figures can one expect from 802.11ac?

Iron

from a firmware development perspective, you should look into open source (sourceforge) where you can find source code for DD-WRT routers, for example.

Blogger

Thanks Fanny for the presentation. Great information.

1ifrpilot asks:

Where would you recommend to learn how to get started using WiFi radios & connecting to routers (from a firmware development perspective)?  Thanks!

 

Blogger

Sherlock, i would suggest Wi-Fi.  LTE uses licensed bands and you would need to deal with an operator, like a Verizon or ATT.

Blogger

yes - the 'pulling into the station' scenario has many challenges other than assocation.  It's like peeling an onion, but first you have to get onto the network and today assocation is a very lengthy process.

Blogger

Thank you for your answer.

Iron

Sherlock asks:

Question if we build the small area wireless image network. Just need consider wi-fi no need LTE? 

Blogger

The all-IP LTE network also has a layer called IMS (IP multimedia subsystem) sitting on top of IP and managing security, QoS, etc. during handovers.  We will discuss this in a later sessioin.

Blogger

Have a great day and see you tomorrow.

Iron

Question about all-IP networks. Does the near-future have TCP/IP and similar existing IP-based technologies on IP? Are new technologies other than TCP and UDP on the way? Does the all-IP networking just use the existing TCP and other layers? 

Iron

Question: You mentioned an example where a train pulls into a station and the local connection point sees a huge spike in traffic. Won't the real challenge be the introduction of enough latency into the traffic stream that QOS becomes an issue? Will every user start experiencing drop outs?

if you go to www.octoscope.com and click on 'publications' you will find additional white papers and other material on the wireless technology topics.

Blogger

LTE uses licensed spectrum, for which you would need operator contract, so i would look into Wi-Fi first for any small area networks.

Blogger

?? Any reference material for further learning on designing with WiFi ?

Iron

What about interference from natural sources such as lightning, solar and cme's?

Iron

Thank you for nice presentation. See you tomorrow

Iron

Higher frequencies don't necessarily require multiple radios if you use devices that only operte at these higher frequencies (e.g. a new TDD deployment in China).

Blogger

Question if we build the small area wireless image network. Just need consider wi-fi no need LTE? 

Iron

Thank you, Fanny

Nice information

 

Iron

regarding the latency question, on LTE octoScope measured in an informal test on the Verizon network about 100 ms of latency, give or take.  I don't know the latencies on 2G and 3G networks, but they are not specified or guaranteed by operators and the architecture is inherently higher latency than LTE.  We will discuss our test in a later session.

 

Blogger

Question: If smaller cells are implimented at higher frequencies, won't that require devices with multiple transmitters and receivers, there by increasing cost and complexity?

Fanny's talk will now be added to the DigiKey Education Center archive for future playback.

Blogger

Thank you very much, lots of info

I appreciate your knowledge and expertise.

Iron

Thanks a bunch.  Good lecture

 

Iron

thank you Fanny that was very informative
I am not very clear about the UNII bands? of the 5 GHz.

 

Iron

Very good lecture, thanks Fanny

Iron

Blogger

Thanks Fanny and Rob.

Iron

Very informative on a dynamic subject.  Thanks Franny

Iron

Where would you recommend to learn how to get started using WiFi radios & connecting to routers (from a firmware development perspective)?  Thanks!

 

Iron

Informative, thanks. Look forward to the future sessions.

Many thanks - a lot of info!

Iron

Morning from Portland Oregon

Iron

I like today's topic. I'm looking forward today's lecture.

Iron

I wonder how the real sprectrum looks like. Most of carriers (AT&T, Verizon, T-Mobile,...) use fixed bandwidth or varying by connection? And how about frequency hopping? Does FDD use fixed frequency until termination or keep hopping frequency?

Iron

Good Morning from GA

Iron

The slides are looking good.

Iron

I m looking forward for the lecture. I review the slide and its very interesting. Here you next week.

Looking forward to the slides and webinar.
