ITU’s new 4G definition ITU has determined that “LTE-Advanced” and “WirelessMAN-Advanced” should be, IMT-Advanced and is considered as “4G”, LTE and WiMax, and to other evolved 3G technologies a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed.
3G vs. 4G 3G (including 2.5G) 4GMajor Requirement Driving Predominantly voice driven - Converged data and voice over IPArchitecture data was always add onNetwork Architecture Wide area cell-based Hybrid - Integration of Wireless LAN (WiFi, Bluetooth) and wide areaSpeeds 384 Kbps to 2 Mbps 20 to 100 Mbps in mobile modeFrequency Band Dependent on country or Higher frequency bands (2-8 GHz) continent (1800-2400 MHz)Bandwidth 5-20 MHz 100 MHz (or more)Switching Design Basis Circuit and Packet All digital with packetized voiceAccess Technologies W-CDMA, 1xRTT, Edge OFDM and MC-CDMA (Multi Carrier CDMA)Component Design Optimized antenna design, multi-band adapters Smarter multi-band adapters Antennas, software multiband and wideband radiosIP A number of air link protocols, All IP (IP6.0) including IP 5.0 From : www.mobileinfo.com
4G Investment – Example #1 Initiative expands wireless coverage to 98% of Americans, reduces deficit by nearly $10 billion, invests in nationwide public safety networkFreeing up 500 MHz of spectrumfor everything from smartphonesto wireless broadband connectivityfor laptops to new forms ofmachine-to-machinecommunication within a decade
4G Investment – Example #2 TeliaSonera 800 MHz band valid for 25 years, cost for licence is 97,000,000 EUR for frequency blocks of 2x10 MHz in the 800 MHz frequency band.
4G Investment – Example #3 Yota - Russia 710-860 MHz €1.49 billion MegaFon, MTS, Vimpelcom would share the network on an MVNO basis.
