Cellular Friendly Hotspots

The rapid and widespread proliferation of Wi-Fi-

enabled devices along with the growth of hotspot

trafﬁc became the drivers for change. According to

the Informa Telecoms & Media, ﬁgures for 2011 put

the total number of Wi-Fi hotspots worldwide at over

1 million. That number is forecasted to take a huge

leap forward and grow 350 percent to nearly 6 million

by 2015.

The Wi-Fi Alliance recently announced the Wi-Fi

Certiﬁed Passpoint program (earlier known as Hotspot

2.0), designed to allow certiﬁed devices to discover

and connect to certiﬁed hotspots. With Passpoint,

a certiﬁed device would automatically discover and

select the hotspot, connect, provide security, and

support roaming agreements. Passpoint is designed to

make Mobile Ofﬂoad more seamless and encourage

increased user adoption.
