Do Usage Caps for Wireless and Mobile Broadband Make Sense?


Consumers say 60 percent of the wireless broadband decision is based on two factors: monthly recurring charge and existence or size of a usage cap. For that reason, "data caps" are a particularly unfriendly way to manage overall traffic, says Yankee Group analyst Philip Marshall. 

A better approach, from a service provider perspective, is to offer unlimited usage and then manage traffic usingreal-time, network intelligence-based solutions like deep packet inspection and policy enforcement, Marshall argues.

Some would argue that fair use policies that throttle maximum speeds when policies are violated is no picnic, either. But temporary limits on consumption, only at peak hours of usage, arguably is more consumer friendly than absolute caps with overage charges. 

To test consumer preferences, Yankee Group conducted a custom survey that included a "choice-based conjoint analysis," which allowed Yankee Group analysts to estimate the relative importance to consumers of key wireless broadband service attributes. The survey was taken by 1,000 mobile consumers who also use broadband access services. 

From the conjoint analysis, "we found that, on average, 59 percent of a wireless broadband purchase decision depends on two factors: service price, and the presence or absence of a 2 GByte per month usage cap," Marshall says. 

The results also indicate that 14.5 percent of a typical purchase decision is affected by service bandwidth, and that the implied average revenue per user lift when increasing bandwidth from 768 Kbps to 2 Mbps ranges between $5 and $10 per month.

The results also indicate, however, that there are diminishing returns for service plans that offer speeds above 3 Mbps, though speed increases might be useful for other reasons, such as competitive positioning. 

"Our price elasticity analysis implies that consumers are willing to pay $25 to $30 more per month for plans that offer unlimited usage, compared to plans that have a 2 GBytes a month usage cap," says Marshall.

"In a competitive operating environment, consumers will tend to migrate toward higher bandwidth services, all else being equal, but they are not necessarily willing to pay a significant premium for the added performance capability," says Marshall.

Our most recent survey results indicate that consumers require 2 Mbps to 3 Mbps bandwidth for their broadband service. This is likely to increase dramatically over the next two to three years, but the consumer survey suggests dramatically-higher bandwidth does not affect decisions as much as recurring price and existence of bandwidth caps. 

For example, when offered a choice between one package featuring a 2 GByte per month usage cap with 6 Mbps bandwidth, and another package with unlimited monthly usage but just 2 Mbps service speed, 63 percent of consumers opted for the 2 Mbps service with no cap.

Even when the choice is between an unlimited package offering only 768 Kbps bandwidth, compared to an alternative plan with 6 Mbps bandwidth and a 2 GByte per month usage cap, 57 percent preferred the 768 kbps package.

Service providers still must manage bandwidth demand though, with or without usage caps
Usage caps work to regulate demand, but users do not like them.

The other approach is not to impose the usage caps, but instead to use policy managment and deep packet inspection to manage traffic flows.

If such solutions are implemented in a non-discriminatory manner, so that all like services are treated equally, they can be implemented irrespective of network neutrality regimes currently under consideration, Marshall believes.

But did those surveyed even know what MBPS they are getting now?

Mike's right. With converged BSS and policy management (incl. real time content adaptation) it's now possible to get away from flat-priced, undifferentiated data bundles and marketing appropriately priced mobile data services, e.g. low priced email/browsing or high priced video streaming.
