Go to 1:50 to skip the intro.

What is the difference between the DSSS (or DSM) and FHSS (or FASST) 2.4GHz modulations? Which modulation is best for you? I think you will find that FHSS/FASST systems are preferable to DSSS/DSM systems, at least when considering the RC hobby.

The FHSS 2.4GHz modulation has better interference resistance, range, and a smaller price tag than the DSM and DSSS 2.4GHz modulations.

The following brands use the FHSS 2.4GHz Modulation:
Airtronics
Futaba (Also has a FASST 2.4GHz Modulation which attempts to utilize the best features of both FHSS and DSSS)

The following brands use the DSSS 2.4GHz Modulation:
Spektrum
RadioPost

I got much of my information about these 2.4GHz Modulations from this source (PDF):

The newest wireless routers are starting to implement a WiFI standard called 802.11ad, which is way faster than N WiFi and even AC WiFi. The AD WiFi uses an incredible 60 GHz frequency, and speeds up to a whopping 4.6 Gbps. However, there are significant drawbacks, such as WiFi range, because that high of a frequency cannot even pass through walls! So, you would have to put any 802.11ad router out in the open, or else the WiFi signal would not propagate. Though I do think there are several uses for this WiFi standard, such as wireless Virtual Reality, which could take advantage of the huge bandwidth and speed of 802.11ad WiFi.

I'm certainly no Salman Khan of the Khan Academy, but I've been doing my little animated presentations for some time and Khan has giving me some inspiration to use YouTube to keep trying the video form factor. I was asked to explain the concept of network latency to someone who found this article on Wall Street's speed wars fascinating using something other than geek talk, so I created this tutorial explaining what is bandwidth, latency, and jitter.

The following is a short 7 minute video I posted on YouTube. As always, feedback and comments are welcome.

Sorry about three places towards the end where audio was recorded too loudly and clipped. The recording software didn't filter out the clipping and these are some of the minor issues I need to hammer out next time. Also note that the 123 miles per millisecond for the "speed of light" quoted is the speed of light in fiber optic cabling. Light travels significantly faster in air and space, around 186 miles per millisecond. And of course, my delivery is certainly not as smooth as Mr. Khan, but I'm hopeful that you'll find the information simple to understand.

One other interesting note is the YouTube switches to a very low bitrate even for the 1080P...

In this video I'm trying to explain why you can't get 100% bandwidth utilization in Ethernet networks. The RFC2544 is pretty old standard using 10Mbit examples, but the results scale up to higher speeds.

For example: During Throughput test using a Smartbits/Ixia test equipment the result of 76.19% would show up as 100% PASS

The example assumes using a test equipment which tests RAW Ethernet throughput and results that you can expect.

The example only focuses on standard Ethernet frames and excludes VLAN frames and Jumbo frames.

Also, there are some transmission equipment that compresses or eliminates certain overhead frames which can skew the results.

I will try to make another video focusing on TCP throughput.

What is 802.11ac?

Avril Salter, Wireless Deployment Specialist, Next Direction Technologies

AC is a new radio. We've had B, A, G, N, and we've now got AC. Why it's really exciting is it's going to go up to much, much higher data rates. It's also going to allow you to have much higher capacity of wireless traffic across your network.

How does it do that? It has several key features. One of the main features is it goes to wider bandwidths. In N, we've go 20 and 40 megahertz, and now we're going to 80 and also an option to go to 160 megahertz, significantly increasing your data rate.

It's also introducing spatial multiplexing up to an 8x8 MIMO. There are 8 antennas, which is pretty amazing if you think about using 8 antennas on this equipment now.

The very first products you're going to see 2013 in the enterprise environment we anticipate will be a 3x3 MIMO. What that one may be able to do is get up to data rates which is over a gigabit per second. We're looking at 1.3...
