US
: Wi-Fi connectivity in the cellular handset will be key to seamless
handoffs between wide and local area networks. Today, we see only
a few handsets that support Wi-Fi. Barriers exist, but when they are
overcome, both mobile operators and consumers will reap the rewards.
The high cost
of the chipset is one inhibitor. But according to ABI Research, that
cost will drop to around US$6.00 by the end of 2004.
Designers face
challenges when building these chipsets into cellular phones, both
in the shrinking physical form factor of the handset, and in light
of signal interference.
Phil Solis, an
ABI Research senior analyst, adds another difficulty: VoWi-Fi uses
more power. But Wi-Fi IC vendors such as Texas Instruments are successfully
working to decrease power consumption.
Some mobile operators
have no clear strategies for extending their data networks using Wi-Fi
hotspots, nor do they see a clear incentive to support Voice-over-Wi-Fi,
because having Wi-Fi in a handset for data could also hurt subscriptions
to cellular data services.
Says Solis, "cellular
providers will bundle multiple wireless services to provide the customer
with access, no matter what the technology is. In ABI Research's opinion,
Wi-Fi and cellular data service are complimentary."
T-Mobile is probably
the most active in promoting Wi-Fi services, but at least a couple
of dozen others have either taken the plunge, or are planning to do
so.
Operators that
bundle Wi-Fi with cellular services will win over consumers. By offering
value-added services, operators can use Wi-Fi in the cellular handset
to retain customers and keep ARPUs level, instead of seeing them drop.
These and other
topics are discussed in ABI Research's report, "Handset Integrated
Circuits Quarterly Service."
