At Least They Didn't Blame the Wi-Fi

Prime Video's stream of the 49ers-Cardinals NFL game received plenty of bad reviews on social media. While most of the negativity focused on stream quality, Wi-Fi largely escaped blame.

There is one application type that confounds networks above all others, and it is live video. Pick your poison: voice, location tracking, on-demand video, cloud-hosted apps... None of them cause problems as consistently or predictably as the livestream.

The issue is a simple one: broadcast vs. two-way. Packetized data networks are a two-way communication medium. Receiver must acknowledge sender. Live video has, since its inception decades ago, been a broadcast technology. Your television doesn't send anything to the local broadcast tower. Same with cable boxes. Same with satellite dishes.

Pushing against this immutable scientific fact is commerce. Sports leagues see the billions of dollars being spent by streaming services, and they want some. Streaming services see the millions of eyeballs tuned into major sporting events, and they want those. The physical limitations of the universe are simply and obstacle to overcome.

The streaming quality issues for Amazon's Twitch & Prime Video broadcast of Saturday's San Francisco 49ers vs. Arizona Cardinals football game were not novel. For years, Major League Baseball's streaming service, MLB.tv, suffered from middling video quality every Opening Day. WWE Network and Disney+ both had signup issues on their respective launch days. 

"You don't build your church for Easter Sunday," is an old Southern proverb. The economics of creating a system designed to handle capacity during extreme outlier events simply don't work. It applies to houses of worship. It applies to networks of data.

For Wi-Fi folks, the good news about Prime Video's problems is that it was a black eye for internet communications, not Wi-Fi. Football fans blamed Amazon. Amazon blamed local internet providers. Nobody -- except the odd Twitter replier -- blamed Wi-Fi.

The bad news for Wi-Fi folks is that our technology faces similar demands as Prime Video's football stream. The economics of most Wi-Fi networks dictate a design for everyday use, but outlier events must be supported.

Your friendly blogger has no silver bullet on bridging the gap between everydays and outliers. Just the advice to keep it in mind. "People will forget what you said and did; they'll remember how you made them feel," is an old Northern proverb. It is also a fine reminder that user anger can have consequences, and few things make Wi-Fi users angrier than an outage at an important time.

    So Ben, in such a scenario, what exactly IS the problem?

      Difficult to say. My guess is local ISPs. Some of them probably do not have networks designed for that much simultaneous live-streaming video.

Go To Sleep, Go To Sleep, Go To Sleep Little iPhone

In some circles, Apple Wi-Fi devices are knows to have problems with lost connections.  iPhones and iPads will unexpectedly miss incoming calls, have delays in receiving push notifications and even be forced to reauthenticate. There is a solution to Apple devices' connection problems, and as with most "device problems", the fix resides on the infrastructure.  The DTIM setting needs to be increased.  ( Apple recommends a setting of 3 or higher .)  Here's why: Some Apple Wi-Fi connection problems stem from Apple iOS devices' use of 802.11 power management.  To understand what Apple devices are doing with power management, one must first understand how 802.11 power management works. Let's start with unicast data.  The 802.11 standard allows devices' Wi-Fi radios to enter the Doze state in order to conserve battery life.  Wi-Fi radios in the Doze state are unable to receive data from the AP, so APs buffer all unicast data that has a destination MAC addr

Why Are You Slowing Down My WiFi, Apple? To Make Things Better?

Image
I defend Apple a lot.  When Network World wrongly accused  the original iPhone of flooding Duke University's network, I defended Apple .  (It was later found to be a Cisco problem.)  When a health care provider I was doing some work for blamed SIP-enabled iPhones for a VoIP problem, I eventually found out that the APs were to blame .  (The APs were failing to respond to WiFi frames tagged as "Background" QoS.)  Time and time again networking folks blame device makers like Apple, and time and time again the problem ends up being the network. There are times, however, when it really is Apple's fault.  When the network is operating just fine.  This is one of those times.  The problem is that I just don't know why. 802.11n (HT) and 802.11ac (VHT) networks operate in co-existence with first generation (802.11a/b/g, that is) WiFi a lot.  When that happens, the HT or VHT access point operates in mixed mode. There are all sorts of ramifications when a WiFi network

Why You Should Stop Disabling Low Wi-Fi Rates, Illustrated

Image
The last Sniff Wi-Fi post; on why Wi-Fi professionals should stop disabling low data rates, was met some resistance.  Be it in the comments  or  on Twitter , several experienced Wi-Fi folks disagreed. All arguments in favor of disabling low rates  (the ones that were presented to me, at least) were refuted in the text of the Leave, Leave, Leave My Rates Alone blog post.  But text is a less accessible messaging method.  "A picture is worth a thousand words", as the old saying goes. If pictures will get the message across better, then pictures are what I'll use.  What follows is an illustrated look at why disabling low data rates is a bad idea. It's gauche to begin an illustrated work with text, but to understand the problem with disabling low Wi-Fi data rates one must first accept some facts about Wi-Fi devices (smartphones, laptops, etc.): 1. Wi-Fi devices -- not APs -- control associations and roaming. 2. Wi-Fi devices roam based on low received signal str
