MBSFN – LTE solution for MBMS
› SFN = Single Frequency Network
› MBMS + SFN = MBSFN
› The same signal is transmitted synchronously from all base-stations
within the same SFN area
– Improves performance higher bitrates possible
– The radio access technology of LTE (OFDMA) is especially well suited for
SFN (no interference between base stations)
33. © Ericsson 2010
Summary
› MBB growing exponentially -> heading towards multi-
service network
› Constant technological and regulatory innovation
needed to keep up with demand in a cost effective
manner
› Multiple antenna arrays, active antennae, wider
bandwidths all contribute to higher end user
bandwidths
› Practical market and business issues mean
introduction will be gradual
Editor's Notes Key messages:
Includes both 3GPP and CDMA networks. (3GPP is measured data, CDMA is estimated data)
Web traffic by mobile PC’s is foreseen to be dominant in the period, driven by the attractiveness of mobile broadband. Web/Mobile PC will grow very strongly and become the dominant application type, including p2p file sharing, music and film downloads etc. The fast-growing applications for data traffic in the large youth segment are web-based services such as YouTube and Facebook.
Traffic per subscriber is in a way related to the screen size available – for a 17” laptop it is relevant to download DVD-resolution movies, but for a handheld device with 2,5” screen much less resolution will suffice – and represent a faster download.
Note uncertainty of the forecast due to being in early stages of development and lack of reporting from operators, as well as operators ability to limit traffic.
Exabyte = 1018 byte

The colors represent ”area binning” over 40m, i.e. each dot represents the average of serveral measurements.
The total experience is actually well on par or better than ADSL2+ (24 Mbps). The Downlink and uplink speeds are better, and the response time is good – of the order of 26 ms (Bredbandskollen actually sometimes report 11ms).
