Downstream will exceed upstream traffic levels on 3G networks by a factor
of more than two - reports
December 10, 2003
A new report from The UMTS Forum into the potential impact of real-world
mobile multimedia applications on use of 3G mobile radio spectrum has
concluded that at least twice as much data traffic will flow to customers
on radio downlinks as will be carried "upstream" from users' mobile devices
to 3G networks.
Available free to UMTS Forum web site visitors, Report #33 - titled "3G
Offered Traffic Characteristics" - examines the nature of traffic driven
by internet, content and other services that is likely to flow across
UMTS networks.

Traditionally, traffic studies for the purpose of spectrum requirement
calculations have only considered the technical characteristics of a mobile
service or application rather than any likely asymmetry in the traffic
characteristics. Mobile multimedia services, therefore, introduce new
challenges driven by the wide variety of multimedia-based activities available
to the user.
Unlike two-way voice communications that are essentially "symmetric"
in their use of radio up- and downlinks, many 3G mobile service categories
- such as web browsing or streaming live video - place greater demands
on the radio downlink than the uplink, with more traffic coming to the
user (downlink) than from the user (uplink). Parameters assessed in the
report that will have an impact on overall traffic flows include: file
sizes for non-real time sessions; expected data rates over up- and down-links
of the air interface; session frequency and duration; "busy hour" traffic
characteristics; and mobile subscribers' adoption of individual 3G services.
Concluding that data traffic on downlinks will exceed uplink traffic
by a factor of 2.3, the report also observes that the possibility exists
for mobile operators to control this asymmetry through their choice of
pricing plans, traffic shaping and service definition.
"There is little historical experience of the varied multimedia, content,
messaging and internet/intranet services that will be supported by UMTS",
comments UMTS Forum Spectrum Aspects Group Chair Anne-Tuulia Leino. "This
is the first cross-industry study that has examined the real-world factors
shaping customers' demand for 3G services and the impact that this is
likely to have on operators' technical, operational and marketing plans."
