reading the title of this post, you might jump to
the conclusion that someone has finally created
technology to effectively control rush-hour
traffic. Sorry, but (so far as we know) that
hasn't happened yet. No, this post is about
continuously steering wireless Internet traffic
back and forth between Wi-Fi and cellular
networks. If things work out as expected, someday
we may no longer make any distinction between
cellular and Wi-Fi networks, but instead talk
about "heterogeneous networks" (HetNets). Nobody
seems to know what this will mean for current
Wi-Fi hotspots.

traffic steering that moves cellular to Wi-Fi

(TechHive/Stephen Lawson) "Software now in the
works will use real-time knowledge about network
conditions to make lightning-fast decisions
about the best system for each user to be on at
a given moment. The idea is that just because
there's a Wi-Fi network nearby, doesn't
necessarily mean your smartphone should start
using it. If every subscriber near that hotspot
got switched over to it, the Wi-Fi experience
could suffer."</li>

(GigaOM/Kevin Fitchard) "HetNets have three
major components. The first is an umbrella - or

mobile broadband coverage. The second is a dense
network of small cells that supply enormous
quantities of bandwidth in the high-traffic
areas its most needed. The final component is a
network intelligence that ties those networks

"The goal is to create better heterogeneous
wireless networks that give users a consistent
experience as they seamlessly shift from 3G and
4G networks to WiFi. Mobile devices often will
shift from broadband to WiFi when an authorized
hotspot is available, which helps lessen the
amount of traffic on already congested broadband
networks and lowers the costs for mobile device
users."</li>
