Mobile operators were out in full force at the International Consumer
Electronics Show in Las Vegas last week, promoting their improved data
networks and unveiling new devices. But with their marketing efforts in
overdrive, the operators may confuse rather than attract users.
AT&T, for example, started calling its current upgraded HSPA+
network 4G instead of 3G. It's not the fastest major network in the
country -- that's Verizon's LTE, based on advertised
speeds -- but AT&T says it has a better transition path to its
next-generation network.
"Today, we're seeing 4G on HSPA+ in markets with enhanced backhaul, with
speeds up to 6Mbps," said Ralph de la Vega, AT&T Mobility's
president and CEO, during his company's developers' summit held at CES.
"We have the best transition path to 4G and we're the only U.S. company
with this plan," de la Vega said.
He is arguing that AT&T's plan is better than Verizon's because once
AT&T starts launching LTE, users will be able to fall back onto the
HSPA+ network, which can deliver as fast as 6 Mbps download speeds. At
CES, AT&T said it will advance its timeline for rolling out LTE,
with launches starting in the middle of this year.
Verizon, however, is going straight from its existing 3G network to LTE,
without an interim step like HSPA+. That means users who aren't in the
LTE coverage areas will drop down to Verizon's slower 3G EV-DO Rev. A (Evolution-Data Optimized) network, which offers
download speeds of around 600 kbps to 1.4 Mbps.
Still, even if Verizon doesn't have AT&T's "4G" HSPA+, it has a head
start on the pack with the faster LTE. Verizon launched LTE in 38
markets in December and last week said it is speeding up its upgrade
path so that another 140 markets will come online this year. Currently, Verizon's LTE network
covers 100 million people, and in 18 months it will reach 200 million
people, Tony Melone, chief technology officer for Verizon, said at CES.
He said the network should offer 5 Mbps to 12 Mbps download speeds.
Further confusing matters, T-Mobile last week also announced new plans
for its own "4G" HSPA+ network, saying that it will double the speed so
that it's capable of delivering an astounding 42 Mbps. That, however,
would be the download rate if just one person were connected at a time
to a cell tower. Operators typically try to offer users a more realistic
approximation of the speed they'll get in a real-life situation when
sharing the network with other people.
To make the situation even more complicated, the International
Telecommunication Union has flip-flopped on what technologies should
officially get the 4G moniker. In November, the ITU's Radiocommunication
Sector said the
only technologies that qualify as 4G will be a future version of
LTE, called LTE-Advanced, and the next generation of WiMax, known as
WirelessMAN-Advanced.
However, in early December it seemed to relent
from that stance. Buried in a press release, it said that LTE and
WiMax may be called 4G since they offer improved performance over 3G.
Consumers may also be confused because the data rates they get
ultimately will depend on whether they have a device that works on the
fastest networks. Currently, the only way to access Verizon's LTE
network is using a USB dongle with a laptop.
Countless new devices were announced last week, few of which are yet
available, to run on all the faster networks. AT&T said it plans to
launch 20 new 4G devices this year, with the first appearing in March.
One of the new phones is the Motorola Atrix, which runs on
HSPA+. The
Atrix can be paired with a docking station that looks like a laptop
but has no CPU.
Verizon
showed off 10 new devices that will run on its LTE network,
including one of the first tablets to run the Honeycomb version of
Google's Android operating system. That tablet, the Xoom, will come from Motorola. The
first version will run on Verizon's 3G network, but buyers will be
eligible for a hardware upgrade later that will make it compatible with
the LTE network. Verizon isn't yet explaining the logistics of such a
hardware upgrade.
