Orange's multi-national Unik/Unique HZ2.0 service
offer, based on DMH and Wi-Fi, is among the most
successful worldwide. Deployed for more than a year in
France, Orange's Unik service has delivered a 10% increase
in average revenue per user (ARPU), and 15% of subscribers
who take the service are new to Orange mobile.
In more recent months, the US has seen the industry's
first femtocell-based HZ2.0 offer. Sprint's Airave service is
currently in limited production, available in just two cities,
but offers a promising glimpse at a femtocell service offer.
Sprint's femtocell is available for a one-time fee of
$49.95. For an additional $15/month, subscribers receive
unlimited calling when in their Home Zone. This offer
compares very favorably with competitive unlimited call-
ing packages. Vonage, for example, offers unlimited in-
home calling for $25/month.
It is interesting to compare Airave
with the US's other HZ2.0 service
offer. T-Mobile's HotSpot @Home
offer is a Wi-Fi-based plan that was
rolled out nationwide in June 2007.
The HotSpot @Home plan offers
unlimited calling from within the
zone for $20/month. A T-Mobile-
branded Wi-Fi access point is avail-
able for $49.95, but subscribers are
able to use their own access points.
One advantage of the HotSpot @
Home service is subscribers can at-
tach to any access point anywhere
in the world and receive discounted
calling. This has made HotSpot @
Home particularly attractive for in-
ternational travelers.

UMA
(Universal Mobile Access) is the
3GPP standard behind the vast
majority of DMH and femtocell-
based HZ2.0 services. With UMA,
mobile operators can now deploy
low-power, low-cost Wi-Fi or
femtocell access points directly into
subscriber homes for dedicated
coverage and capacity, as well as
leverage broadband access and the
internet for low-cost mobile service backhaul.
UMA supports both 2G and 3G core network services.
UMA network controllers can typically support either DMH
or femtocell services, offering flexibility and protection for
operators investing in a Home Zone infrastructure.
Stéphane Téral, principal analyst with Infonetics
Research, recently completed an exhaustive report on the
fixed-mobile convergence (FMC) market. In the report,
Infonetics forecasts the FMC market, including UMA
network controllers, multi-access convergence gateways,
and dual-mode cellular/WiFi phones will grow to $46.3
billion by 2010. At the conclusion of his analysis, Teral
commented: "For those who still believe UMA will be
short lived, it can now support 3G, is backed by the 3GPP,
has a clear migration roadmap to IMS and is becoming the
default case for femtocells."
