A web guy and a telecom guy talk about net neutrality

It was a nondescript bar in the American Midwest, the sort of place where working men drop in at the end of the day to unwind before they head home. You wouldn't expect to find two senior business executives there, and as I sat in the empty bar at midday I wondered if maybe my contact had given me a bad lead. But then the door opened and a general manager from one of the leading web companies walked in, followed by a senior VP from one of the US's biggest mobile network operators. I hunched down in the shadows of a corner booth and typed notes quietly as they settled in at the bar.

Bartender: What'll you have?

Telecom executive: Michelob Light.

Web executive: I'll have a Sierra Nevada Kellerweis.

Bartender: Keller-what?

Web executive: Um, Michelob Light.

Telecom executive: Thanks for coming. Did you have any trouble finding the place?

Web executive: All I can say is thank God for GPS. I've never even been on the ground before between Denver and New York.

Telecom executive: I wanted to find someplace nondescript, so we wouldn't be seen together. The pressure from the FCC is bad enough already, without someone accusing us of colluding.

Web executive: No worries, my staff thinks I'm paragliding in Mexico this weekend. What's your cover story?

Telecom executive: Sailboat off Montauk.

Web executive: Sweet. So, you wanted to talk about this data capacity problem you have on your network...

Telecom executive: No, it's a data capacity problem we all have. Your websites are flooding our network with trivia. The world's wireless infrastructure is on the verge of collapse because your users have nothing better to do all day than watch videos of a drunk guy buying beer.

Web executive: Welcome to the Internet. The people rule. If you didn't want to play, you shouldn't have run the ads. Remember the promises you made? "Instantly download files. Browse the Web just like at home. Stream HD videos. Laugh at an online video or movie trailer while travelling in the family car."

Telecom executive: That was our marketing guys. They don't always talk to the capacity planners. Besides, who could have known that the marketing campaign would actually work?

Web executive: Don't look at me. I've never done a marketing campaign in my life. I think you should just blame it on A--

Telecom executive: You promised, no using the A-word.

Web executive: Sorry. But I still don't see why this is a problem. Just add some more towers and servers and stuff.

Telecom executive: It's not that simple. The network isn't designed to handle this sort of data, and especially not at these volumes. Right now our biggest problem is backhaul capacity -- the traffic coming from the cell towers to our central servers. But when we fix that, the cell towers themselves will get saturated. Fix the towers and the servers will fall over somewhere. It's like squeezing a balloon. We have to rebuild the whole network. It's incredibly expensive.

Web executive: So? That's what your users pay you for.

Telecom executive: But most of them are on fixed-rate data plans. So when we add capacity, we don't necessarily get additional revenue. It's all expense and no profit. At some point in the not-too-distant future, we'll end up losing money on mobile data.

Web executive: Bummer.

Telecom executive: More like mortal threat. Fortunately, we've figured out how to solve the problem. The top five percent of our users produce about 50% of the network's total traffic. So we're just going to cap their accounts and charge more when they go over.

Web executive: Woah! Hold on, those are our most important customers you're talking about. You can't just shut them down.

Telecom executive: The hell we can't. They're leeches using up the network capacity that everyone else needs.

Web executive: Consumers will never let you impose caps. You told them they had unlimited data plans, that's the expectation you set. You can't go back now and tell them that their plans are limited. They won't understand -- and they won't forgive you.

Telecom executive: First of all, the plans were never really unlimited in the first place. There's always been fine print.

Web executive: Which no one read.

Telecom executive: Off the record, you may have a point. On the record, the fact is that you can retrain users. Look, you grew up in California, right?

Web executive: What does that have to do with anything?

Telecom executive: Once upon a time, there weren't any water meters in California. Now most of the major cities have them, and they'll be required everywhere in a couple of years. Something that was once unlimited became limited, and people learned to conserve.

Web executive: The difference is, I can read my water meter. You make a ton of money when people exceed their minutes or message limits, and you don't warn them before they do it. If you play the same game with Internet traffic, it'll scare people away from using the mobile web -- or worse yet you'll invite in the government. Look what happened with roaming charges in Europe.

Telecom executive: Jeez, don't even think about that. Okay, so we'll need to add some sort of traffic meter so people will know how much data they're using when they load a page.

Web executive: Great, that'll discourage people from using Yahoo.

Telecom executive: Huh?

Web executive: Oops, did I say that out loud?

Telecom executive: Then there's the issue of dealing with websites and apps that misuse the network.

Web executive: Not this again.

Telecom executive: I'm not talking about completely blocking anything, just prioritizing the traffic a little. Surely you agree that 911 calls should get top priority on the network, right?

Web executive: Of course.

Telecom executive: And that voice calls should take priority over data?

Web executive: I don't know about that.

Telecom executive: Oh come on, what good is a telecom network if you can't make calls on it?

Web executive: (sighs) Yeah, okay.

Telecom executive: So then what's wrong with us prioritizing, say, e-mail delivery over video?

Web executive: Because when you start arbitrarily throttling traffic, I can't manage the user experience. My website will work great on Vodafone's network but not on yours, or my site will work fine on some days and not on others. How do you think the customers will feel about that?

Telecom executive: Not as angry as they will be if the entire network falls over. Listen, we're already installing the software to prioritize different sorts of data packets. We could be throttling traffic today and you wouldn't even know it.

Web executive: But people will eventually figure it out. They'll compare notes on which networks work best and they'll migrate to the ones that don't mess with their applications. Heck, we'll help them figure it out. And if that's not enough, there's always the regulatory option. The Republicans are out of office. They can't protect you on net neutrality any more.

Telecom executive: You think you're better at lobbying the government than we are? We've been doing it for 100 years, pal. Besides, we have a right to protect our network.

Web executive: You mean to protect your own services from competition!

Telecom executive: Parasite!

Web executive: Monopolist!

Telecom executive: That's it! It's go time!

They both stood. The telecom guy grabbed a beer bottle and broke it against the bar, while the web guy raised a bar stool over his head. Then the bartender pulled out a shotgun and pointed it at both of them.

Bartender: Enough! I'm sick of listening to you two. Telecom guy, you're crazy if you think people will put up with someone telling them what they can and can't do on the Internet. The Chinese government can't make that stick, and unlike them you have competitors.

Web executive: See? I told you!

Bartender: Shut up, web guy! You keep pretending that the wireless network is infinite when you know it isn't. If you really think user experience is important, you need to start taking the capabilities of the network into account when you design your apps.

Web executive: Hey, he started it.

Telecom executive: I did not!

Bartender: I don't care who started it! Telecom guy, you need to expose some APIs that will let a website know how much capacity is available at a particular moment, so they can adjust their products. And web guy, you need to participate in those standards and use them. Plus you both need to agree on ways to communicate to a user how much bandwidth they're using, so they can make their own decisions on which apps they want to use. That plus tiered pricing will solve your whole problem.

Telecom executive: Signaling capacity too. Don't forget signaling.

Bartender: That's exactly the sort of detail you shouldn't confuse users with. Work it out between yourselves and figure out a simple way to communicate it to users. Okay?

Web executive: I guess.

Telecom executive: Yeah, okay.

Bartender. Good. Now sit down and start over by talking about something you can cooperate on.

Telecom executive: All right. Hey, what's that guy doing in the corner? Is that a netbook?

Web executive: He's a blogger!

Bartender: There's no blogging allowed in here!

Telecom executive and web executive: Get him!

I ran. Fortunately, the bar had a back door. Even more fortunately, the web guy and the telecom guy got into an argument over who would go through the door first, and I was able to make my escape.

So I don't know how the conversation ended. But I do know that I wish that bartender was running the FCC.

Mobile data: Be careful what you wish for

The consensus around the industry seems to be that mobile data is starting to take off. Text messaging is still the leading data function, accounting for about 65% of total data revenue, according to Informa (link). But Nielsen reports a steady rise in the number of mobile Internet subscribers (link), and a faster increase in revenue (implying that those who do use the mobile web are increasing their online activity). Young people are apparently important drivers in the increase, with 37% of US adults age 18 to 24 using their phones to access the web, according to the Mobile Marketing Association (link).

The cause is supposedly not just the iPhone and other smartphones; what I'm hearing from multiple companies is that web access and other data usage is rising even on feature phones.

This increased activity is creating an uncomfortable problem for some mobile operators: it's apparently overloading their networks. There have been predictions for years that this could happen -- a report from 2005 pointed out that the typical 3G network would be overloaded if 40% of subscribers used video just eight minutes a day (link). It predicted potential traffic overload by 2007. There have been charges that service problems on the AT&T network in the US have been caused by the iPhone (link).

In the UK, the BBC's popular iPlayer streaming video service is supposedly threatening the economics of even wired ISPs (link -- very interesting article), so it's easy to imagine what it could do to mobile networks if broadly deployed. Supposedly the mobile version of iPlayer for Nokia S60 is set up to stream only over WiFi, but the discussion here (link) points out that restriction is likely to be evaded by enterprising users.

It's very hard to confirm exactly what mobile data is doing to the networks because the operators don't like to discuss this sort of thing in public. But the number of data-capable phones is definitely growing faster than network capacity, so overload is just a matter of time. I've gotten several off-the-record comments from friends in the industry saying that the operators are worried about the problem and are quietly trying to throttle traffic, especially to online multimedia services that consume a lot of bandwidth.

The problem is complicated by the all-you-can-eat data plans that have been adopted by many operators. If you're charging people for the amount of data they consume, their data use becomes self-limiting. But limited plans are unpopular with users, who get practically unlimited data on their PC web connections. When you tell people that they can have the web on their mobiles, they expect to be able to use it like the web they already know.

So the operators are stuck with either throwing out people who use the "unlimited" network heavily, or covertly degrading the quality of their service so they'll stop using so much data. Both practices are very dangerous to their long-term prospects.

The problem is that the people who use a lot of data aren't just the freakish fanatics that the industry would like to imagine them as. They are Internet power users, a group that we labeled the Most Frequent Contributors (MFCs) when we recently researched Internet usage patterns at Rubicon (link). They don't just use a lot of video -- they are generally very involved in all sorts of online activities. Most importantly for the operators, they write the majority of the reviews and user comments posted online.

So, if you kick a power user off your network, or throttle their performance, they are extremely likely to write about you online. Extensively. Where their complaints will be read by most other Internet users. Check out the comments here and here if you want a sample.

Systematically punishing your noisiest customers is not the way to build a sustainable business.


What else can the operators do?

I wish there were some magical formulation that would make users happy and operators financially sound. But there isn't, because the problem is inherent to the way a wireless network operates. And as the installed base of smartphones grows, and video and other multimedia services increase in popularity, the problem is only going to get worse.

The most damaging approach is that one that operators seem to be leaning toward now, covertly throttling traffic. They can probably get away with that for a while, but eventually people online will compare notes, figure out that network performance is being systematically distorted -- and then the class-action lawyers (in the US) and government regulators (in Europe) will be unleashed.

Honesty is the best policy. Ultimately I think there's no alternative to moving to pricing plans that acknowledge the physical limits on the wireless Internet. That, and the operators need to resist the temptation of advertising their Internet as identical to the wired Internet. The MFCs are technically sophisticated, and capable of understanding the need for tiered pricing if it's explained to them clearly and honestly. What causes endless friction is the hypocrisy of calling something "unlimited" and then limiting it.
