The installation, and incomplete configuration, of a new router and a fiber link failure, both in the southeast U.S., combined with software and hardware bugs to take down T-Mobile’s national phone network in June, according to a report published in October by the Federal Communications Commission. The cascade of problems that began with a fiber route going down led to a “registration storm” in Atlanta as “mobile devices repeatedly attempted and failed to register” on the network, first using 4G, 3G and 2G mobile systems, and finally trying to complete calls via WiFi connections.… More

Mobile carriers use arbitration board to debunk each other’s ads

The three major U.S. mobile carriers are fighting each other’s advertising claims via an arbitration process run by the Better Business Bureau. First, it was T-Mobile who successfully challenged AT&T’s 5GEvolution scam. The BBB’s National Advertising Division (NAD) said that putting a 5G label on 4G service was misleading, and the appeals board run by BBB agreed.

Verizon objected to T-Mobile’s wide-ranging claims of wide ranging 5G coverage and NAD agreed, albeit while blessing verbiage about the superior building penetration ability of the low band spectrum it’s using.… More

Ad watchdog says some T-Mobile 5G claims are bogus, some aren’t

T-Mobile’s ads about the wonderfulness of its 5G network and the limitations of Verizon’s went too far, according to an independent watchdog. The national advertising division (NAD) of the Better Business Bureau, which has been acting as a mobile broadband advertising referee lately, said that T-Mobile supported its claim that its 5G service is faster than its competitors and covers more ground, but was misleading about metrics and its ability to project 5G service into places where even 4g is troublesome…

NAD noted that the challenged claims also convey a message about metrics other than speed.

AT&T continues 5GEvolution scam despite advertising industry’s slapdown

A self-regulating body set up by the advertising industry slapped down AT&T’s strategy of conning mobile subscribers into thinking that they’re getting 5G service when they’re really connected to a 4G network. The National Advertising Review Board (NARB), which is run by the Better Business Bureau, concluded that AT&T’s decision to slap a “5G Evolution” label or, more confusingly, a 5GE icon, on its LTE service is misleading and that “consumers may well interpret “Evolution” in the challenged claims as signifying that AT&T’s technology has already evolved into 5G”.… More

AT&T’s 5GE scam is unravelling. Measurements taken by an independent testing company, OpenSignal, show that slapping a phony 5G label on upgraded 4G LTE service does not make the user experience any faster.

According to OpenSignal’s blog post…

Some AT&T users in the U.S. have recently seen “5G E” appear on the status bar of their existing smartphones, replacing 4G. This move has sparked controversy because AT&T is using updated 4G network technologies to connect these smartphone users, not the new 5G standard…

Analyzing Opensignal’s data shows that AT&T users with 5G E-capable smartphones receive a better experience than AT&T users with less capable smartphone models…But AT&T users with a 5G E-capable smartphone receive similar speeds to users on other carriers with the same smartphone models that AT&T calls 5G E.

AT&T’s theory of Evolution assumes its customers aren’t highly Evolved

Att customer evolution

AT&T subscribers will get 5G on their smartphones soon. No, not 5G service. Just a “5” and a “G” and a little bitty “E” at the top of their screens, where it now says “4G”. It’s a branding move, and not a particularly honest one. About a year ago, AT&T announced it was relabelling its 4G upgrades as 5G Evolution (that’s what the little E stands for).

According to a story in Fierce Wireless by Mike Dano…

AT&T…introduced the “5G Evolution” marketing label to cover markets where it offers advanced LTE network technologies…AT&T has argued that such technologies pave the way for eventual 5G services, though critics have argued that AT&T’s “5G Evolution” marketing moves only serve to sow confusion among consumers.

4G is not 4G without the backhaul to support it

“4G is not 4G without the backhaul to support it,” said Sara Kaufman, an analyst who follows mobile operator strategy for Ovum, speaking today at the CTIA Enterprise & Applications conference in San Diego. Mobile carriers have to start by connecting cell sites to fiber networks when they upgrade their networks to 4G speeds using LTE technology.

She predicted robust growth for LTE-based 4G mobile data service in the U.S., but had trouble explaining exactly why.… More

FCC chairman Julius Genachowski delivered the opening keynote at the CTIA IT and Entertainment conference today. He offered good of idea of what he has in store for the industry, and gave us a feeling for who he is.

If you take him at face value, the FCC is going to be the wireless industry’s best friend. And the consumer’s best friend. In fact, everybody’s best friend.

Genchowski unveiled what he called the FCC’s mobile broadband agenda:
