A Verizon Wireless 4G/LTE customer that managed to consume nearly 56GB of data over a two-week period has found he has temporarily lost his 4G privileges during peak usage times on Verizon’s network.

Droid Life reports Verizon’s speed throttle apparently also works on the company’s much-faster 4G network, because the customer found his 4G speeds reduced to dial-up during peak usage periods.  The throttle reduces speeds so much, even browsing web pages becomes a painful experience.  Remarkably, the customer tells Droid Life he still has regular speed access to Verizon’s more congested 3G network, which he now uses when his 4G speeds are reduced.

Verizon Wireless specifically exempts 4G customers from wholesale enforcement of their speed throttle, but the company’s standard Acceptable Use Policy still gives Verizon broad latitude to deal with customers who create an “adverse impact” on their network:

Network disruptions and unfriendly activity: Using the Services for any activity that adversely affects the ability of other people or systems to use either Verizon Wireless Services or other parties’ Internet-based resources. This specifically but without limitation includes excessive consumption of network or system resources whether intentional or unintentional. This also includes “denial of service” (DoS) attacks against another network host or individual user. Interference with or disruption of other network users, network services or network equipment is prohibited.

Such policies are commonplace at every Internet Service Provider, but they are typically enforced only in instances where a neighborhood or region is experiencing especially heavy traffic loads.  That seems to be the case with Droid Life‘s reader, because other customers report they have managed to rack up nearly 120GB in 4G usage over 10 days with no speed reductions.  Verizon reportedly told the throttled customer his speeds were reduced because his ‘excessive downloading’ was an “abuse of the network.”

To run up tens of gigabytes of usage over two weeks usually means the customer is using a tethering application or mobile hotspot app, services for which Verizon charges extra.  We don’t know if this customer is paying for those services or using one of the third-party apps Verizon frowns on.

The selective enforcement of speed throttles may be the result of an overeager Verizon employee subjectively cracking down.  It might also result from the subscriber using services on an especially congested cell site.  We cannot be certain, and Verizon isn’t commenting on the record.  The company officially claims it is standing by the terms of its original plans to throttle the top 5% of 3G users.

With the ongoing crackdowns on what providers deem to be “excessive usage,” it is safe to assume those attempting to use any wireless broadband plan as a home or office broadband replacement is risking the wrath of their providers who consider anything beyond 2-4GB of usage per month on an “unlimited data plan” to be “too much.”

Sprint, the last remaining major national wireless carrier without an Internet Overcharging scheme, will adopt one of its own on Oct. 2 when it begins limiting 3G/4G Mobile Hotspot customers to just 5GB of usage per month with a huge $50/GB overlimit fee (charged in megabyte increments).

SprintFeed shared the details in a copy of a leaked internal company newsletter announcing the changes:

It is important to note Sprint currently plans no usage limits on their tablet or smartphone customers — this usage cap only applies to customers signed up for the Mobile Hotspot option who use their phone’s Wi-Fi feature to connect other wireless devices.  Those with third-party tethering apps or other “unofficial” tethering schemes won’t face the usage cap either, so long as Sprint does not initiate a crackdown on customers without a company-sanctioned tethering plan.

Customers will automatically be “migrated” to the new $29.99 usage-limited Mobile Hotspot plan in October.  Affected customers will be notified of the changes in bill messages or postcards.  Sprint will not grandfather existing customers.

Some Sprint customers claim the company has always had a “secret 5GB cap” on the Mobile Hotspot feature, only enforced when customers considerably exceeded it, but this makes it official.

Sprint may be preparing its network for the introduction of iPhone 5, which Sprint is rumored to introduce early next month.

AT&T and Verizon: The Doublemint Twins of Wireless

Mirroring AT&T’s announcement last month that it would begin implementing speed throttles for wireless unlimited data plan customers who are among the “top 5% of users,” Verizon Wireless quietly made changes last week allowing the company to throttle its own unlimited data plan “heavy users” who consume more than 2GB of usage per month on its 3G network.

But Verizon claims it isn’t actually throttling the speeds of customers, it is simply engaging in “network optimization practices” and using “network intelligence” to reduce speeds (sometimes to near-dial-up) while connected to a “congested cell site.”

That will prove a distinction without much difference to customers who rely on 3G data usage using cell sites Verizon deems congested.  They may also find the time spent in Verizon’s penalty box unusually long.

“You may experience [reduced speeds] for the remainder of your then current bill cycle and immediately following bill cycle,” Verizon’s FAQ states.

That can mean customers paying $30 a month for an “unlimited data plan” may find 3G usage a very slow experience for a maximum of two months before they are off Verizon’s throttle list.

The new speed throttle policy began Sept. 15.  Verizon:

Network Optimization practices and throttling is network intelligence.  With throttling, your wireless data speed is reduced for your entire cycle, 100% of the time, no matter where you are. Network Optimization is based on the theory that all customers should have the best network possible, and if you’re not causing congestion for others, even if you are using a high amount of data, your connection speed should be as good as possible. So, if you’re in the top 5% of data users, your speed is reduced only when you are connected to a congested cell site. Once you are no longer connected to a congested site, your speed will return to normal. This could mean a matter of seconds or hours, depending on your location and time of day.

Verizon has not said exactly how many of its cell sites it deems as “congested,” at what times that congestion is most likely to occur, and admits there is currently no way customers can learn when they are connected to a congested site so they can make an informed decision about their usage.

But the company does say customers can avoid the penalty:

1. Upgrade to a 4G phone and hope for good 4G LTE coverage.  Customers using Verizon’s 4G network are not currently subject to a speed penalty for “excessive use.”
2. “Upgrade” to a tiered data plan with usage allowances.  Verizon will not throttle the speeds of customers who are not on unlimited data plans.
3. Reduce your data usage, especially in areas where congestion is likely.

Choke collars are in season at AT&T and Verizon Wireless, leaving Sprint's unlimited service looking more consumer-friendly by the day.

Those suggestions require potentially pricey new handsets, require customers to abandon their existing unlimited data usage plan, or simply get you thinking twice before launching a data session, fearing being grounded for up to two months with a dramatically reduced level of service.

The biggest impact of the network speed throttles will be among data-heavy iPhone users.  Apple’s iPhone doesn’t support 4G, and is likely to continue to rely on 3G network coverage when the next version of the popular phone is introduced in October.  Ultimately, Verizon’s new policy means iPhone devotees using more than 2GB per month may have to abandon their phone or their unlimited data plan if they want to avoid the throttle.

Verizon also found a way to keep customers from canceling penalty-free, noting contract changes that reserved the right to implement network management techniques were made in February.  The 60-day window for the “materially-adverse” contract change cancellation policy expired in April.  Verizon:

By alerting customers in February 2011, and including the notice in our terms and conditions as of February 3, 2011, we made sure customers knew we began reserving the right to implement Network Optimization practices.  In February 2011, we began alerting customers:

• Data Management – (note: now named “Network Optimization” to more accurately describe the tools) – Verizon Wireless may reduce data throughput speeds in a given bill cycle for customers who use an extraordinary amount of data and fall within the top 5% of data users.  The reduction will only apply to those using congested cell sites and can last for the remainder of the current and immediately following billing cycle.  The reductions will only apply when appropriate in locations and at times of peak demand.
• Data Optimization – (note: now named “Video Optimization” to more accurately describe its function) – Verizon Wireless is implementing optimization and transcoding technologies in its network to transmit data files in a more efficient manner to allow available network capacity to benefit the greatest number of users, and although unlikely, the process may minimally impact the appearance of the file as displayed on the mobile device.

Interestingly, AT&T’s own speed throttle penalty was estimated to kick in after 4GB of usage, not the 2GB Verizon is using as its benchmark for “network optimization.”  Verizon also says customers with their Mobile Hotspot feature will find that usage exempted from counting towards the 2GB threshold.

Verizon has opened up a new web page explaining the throttling policy.

While wireless providers currently treat Wi-Fi as a friendly way to offload wireless data traffic from their 3G and 4G networks, the wireless industry is starting to ponder whether they can also earn additional profits from regulating your use of it.

Dean Bubley has written a white paper for the wireless industry exploring Wi-Fi use by smartphone owners, and ways the industry can potentially cash in on it.

“It is becoming increasingly clear that Wi-Fi access will be a strategic part of mobile operators’ future network plans,” Bubley writes. “There are multiple use cases, ranging from offloading congested cells, through to reducing overseas roaming costs and innovative in-venue services.”

Bubley’s paper explores the recent history of some cell phone providers aggressively trying to offload traffic from their congested 3G networks to more-grounded Wi-Fi networks.

Among the most intent:

• AT&T, which acquired Wayport, a major Wireless ISP, and is placing Wi-Fi hotspots at various venues and in high traffic tourist areas in major cities and wants to seamlessly switch Apple iPhone users to Wi-Fi, where available, whenever possible;
• PCCW in Hong Kong;
• KT in the Republic of Korea, which has moved as much as 67 percent of its data traffic to Wi-Fi;
• KDDI in Japan, which is planning to deploy as many as 100,000 Wi-Fi Hotspots across the country.

America's most aggressive data offloader is pushing more and more customers to using their Wi-Fi Hotspots.

Bubley says the congestion some carriers experience isn’t necessarily from users downloading too much or watching too many online shows.  Instead, it comes from “signalling congestion,” caused when a smartphone’s applications demand repeated attention from the carrier’s network.  An application that requires regular, but short IP traffic connections, can pose a bigger problem than a user simply downloading a file.  Moving this traffic to Wi-Fi can be a real resource-saver for wireless carriers.

Bubley notes many wireless companies would like to charge third-party developers fees to allow them access to each provider’s “app store.”  Applications that consume a lot of resources could be charged more by providers (or banned altogether), while those that “behave well” could theoretically be charged a lower fee.  The only thing preventing this type of a “two-sided business model,” charging both developers and consumers for the applications that work on smartphones, are Net Neutrality policies (or the threat of them) in many countries.

Instead, Bubley suggests, carriers should be more open and helpful with third party developers to assist them in developing more efficient applications on a voluntary basis.

Bubley also ponders future business strategies for Wi-Fi.  He explores the next generation of Wi-Fi networks that allow users to establish automatic connections to the best possible signal without ponderous log-in screens, and new clients that can intelligently search out and connect to approved networks without user intervention.  That means data traffic could theoretically be shifted to any authenticated or preferred Wi-Fi network without users having to mess with the phone’s settings.  At the same time, that same technology could be used to keep customers off of free, third party Wi-Fi networks, in favor of networks operators run themselves.

Policy controls are a major focus of Bubley’s paper.  While he advocates for customer-friendly use of such controls, sophisticated network management tools can also be used to make a fortune for wireless providers who want to nickle and dime customers to death with usage fees, or open up new markets pitching Wi-Fi networks to new customers.

Bubley

For example, a wireless carrier could sell a retail store ready-to-run Wi-Fi that pushes customers to a well-controlled, store-run network while customers shop — a network that forbids access to competitors or online merchants, in an effort to curtail browsing for items while comparing prices (or worse ordering) online from a competitor.

Customers could also face smartphones programmed to connect automatically to a Wi-Fi network, while excluding access to others while a “preferred” network is in range.  Wireless carriers could develop the same Internet Overcharging schemes for Wi-Fi use that they have rolled out for 3G and 4G wireless network access.  Also available: speed throttles for “non-preferred” applications, speed controls for less-valued ‘heavy users,’ and establishment of extra-fee “roaming charges” for using a non-preferred Wi-Fi network.

Bubley warns carriers not to go too far.

“[We] believe that operators need to internalize the concept of ‘WiFiNeutrality’ – actively blocking or impeding the user’s choice of hotspot or private Wi-Fi is likely to be as divisive and controversial as blocking particular Internet services,” Bubley writes.

In a blog entry, Bubley expands on this concept:

I’m increasingly convinced that mobile device / computing users will need sophisticated WiFi connection management tools in the near future. Specifically, ones that allow them to choose between multiple possible accesses in any given location, based on a variety of parameters. I’m also doubtful that anyone will want to allow a specific service provider’s software to take control and choose for them – at least not always.

We may see the emergence of “WiFi Neutrality” as an issue, if particular WiFi accesses start to be either blocked or “policy-managed” aggressively.
