alt="" height="82" width="128"></a>The
continuing explosive growth in the amount of data
being transmitted to and from mobile devices is
causing headaches for wireless carriers. One
option for dealing with this demand is to offload
as much data as possible onto Wi-Fi access points,
which are more efficient than connecting devices
through 3G, 4G, LTE, or other cell phone
technologies. This year, the Wi-Fi Alliance is
working to develop a standard called Passpoint
that would let mobile devices connect
automatically to Wi-Fi hotspots, possibly
including hotspots in public libraries, just as
they now automatically connect to cell phone
towers. How this would work is not exactly clear
yet - would carriers pay libraries for handling
some of their customer traffic, for instance? -
but it's a development that certainly bears
watching.

Passpoint could make Wi-Fi hotspots more like
cellular data services</a> (Network World/Brad
Reed) "Known as the Wi-Fi Certified Passpoint
program, the initiative essentially creates a
database of Wi-Fi hotspots and allows you to
access any in your area that take part in the
program. What's more, any hotspots that take
part in Passpoint will allow you to connect
without entering in any login or billing
information since the program supports
Subscriber Identity Module (SIM)-based
authentication that cellular networks currently
use to grant users seamless handoffs between
cell sites."</li>

Passpoint standard could end hotspot sign-on
hassles</a> (Computerworld/Stephen Lawson)
"The most obvious advantage of the Passpoint
standard may be doing away with the browser
'splash screens' that greet visitors to most
public hotspots. Instead, admission to the
network will happen in the background, through a
variety of mechanisms that can include an SIM
(Subscriber Identity Module) card and
certificate-based methods."</li>
