4 Subscribers and traffic growth 50 Billion Exabyte Billion 2010 Few Exabyte 2010 CONNECTED DEVICES Traffic growth Public Ericsson AB Page 4
5 Network requirements (2012) Dongles Peakrates: 100 Mbps Customer accepts: 10/2 Mbps Volume: 5 GB/month Tablets Peakrates: 40 Mbps Customer accepts: 5/1 Mbps Volume: 2 GB/month Smartphones Peakrates: 10 Mbps Customer accepts: 2/0.5 Mbps Volumes: 500 MB/month Public Ericsson AB Page 5
6 expectations increase Uplink average rate 3 Mb/s? Typical DL today: 1 Mbps Typical UL today: 500 kbps +50% per year 10 kb/s +50% per year 400 kb/s 600 kb/s? No change? Time Public Ericsson AB Page 6
7 End User Experience Challenges with existing solution Data rate Increase overall cellsite performance 2. Increase cell edge data rates 3. Increase indoor data rates Public Ericsson AB Page 7
8 The Radio Network Toolbox addressing future end user demands Data rate Evolved macro Evolved macro WiFi Micro, Pico, Relays 1. Evolved Macro advanced antennas, spectrum aggregation, advanced Rx 2. More Cells Site densification, Small cells main remote, relays, pico, WiFi 3. Dedicated indoor/enterprise solutions as part of mobile operator offering Public Ericsson AB Page 8
9 MBB User experience target European Example Assets 900/1800/2100/2600 MHz Macro & micro sites 70% indoor traffic Macro site-to-site ~350 m Macro densification (30-40% more sites) Bitrate targets HSPA devices Cell edge [Mbps] LTE devices Cell edge [Mbps] DL UL ( ) 0.5 ( ) GB / Month / Subscriber Operator requirement European Average WiFi traffic not included Public Ericsson AB Page 9
