  6. 6.  In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the IMT- Advanced.  Set peak speed requirements for 4G service at 100 Mbit/s for high mobility communication and 1 Gbit/s for low mobility communication.  The peak bit rate is further improved by smart antenna arrays for multiple-input multiple-output (MIMO) communications.  A 4G system does not support traditional circuit switched telephony service, but all-Internet Protocol (IP) based communication such as IP telephony. 7Mobile Computing and Wireless Communication
  7. 7.  4G is the fourth generation of mobile phone mobile communication technology standards.  It is a successor to the third generation (3G) standards.  A 4G system provides mobile “ Ultra Broadband speed” – to be counted in gigabytes per second.  This technology is currently available in some countries but it is still being perfected. 8Mobile Computing and Wireless Communication
  8. 8. 9Mobile Computing and Wireless Communication TECHNOLOGY 3G 4G Developed 2001 2010 Services voice quality & always on Broadband Data data & voice over IP, LTE Standard IMT-2000 (UMTS, WCDMA, CDMA2000) Single Standard based on LTE Advanced Architecture Circuit & Packet Switched Packet Switched Multiplexing CDMA OFDM+ MIMO, W-OFDM, MC-CDMA Core Network PSTN & Some IP Networks Completely IP based Data Rates 384 Kbits/s to 3.1 M bits/s 100 M bps to 1G bps
  9. 9.  System key components of 4G 10Mobile Computing and Wireless Communication
  10. 10. a) System standards  LTE Advance , WiMAX 2 b) Multiplexing and access schemes  OFDM+ MIMO, W–OFDM, MC-CDMA c) IPv6 SUPPORT d) Advanced antenna systems  Multiple antenna technologies are used to achieve high rate, high reliability and long communication range. e) Software-defined radio (SDR)  Standards constituted by a 4G device can be realized using SDR 11Mobile Computing and Wireless Communication
  11. 11. 7TH MOBILE COMM STANDARD 12Mobile Computing and Wireless Communication  Long Term Evolution (LTE) is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth.  LTE uses Orthogonal Frequency Division Multiple Access (OFDMA) on the downlink, which is well suited to achieve high peak data rates in high spectrum bandwidth.
  12. 12. 13Mobile Computing and Wireless Communication  Orthogonal frequency-division multiplexing (OFDM) is a frequency division multiplexing (FDM) scheme that uses a digital multi-carrier modulation method.  OFDM uses the spectrum more efficiently by making all the sub-carriers orthogonal to one another, using fast Fourier transform (FFT) to prevent interference between the closely spaced sub-carriers.  In OFDM, the guard band is reduced by the orthogonal packing of the subcarriers, improving the spectral efficiency .

  20. 20. 21Mobile Computing and Wireless Communication (OTP) (OWA)
  21. 21. 22Mobile Computing and Wireless Communication  OSI layer 1 & OSI layer 2 define the wireless technology.  For these two layers the 5G mobile network is likely to be based on Open Wireless Architecture (OWA).  Physical layer + Data link layer = OWA
  22. 22. 23Mobile Computing and Wireless Communication  All mobile networks will use mobile IP  Each mobile terminal will be FA (Foreign Agent)  A mobile can be attached to several mobiles or wireless networks at the same time  The fixed IPv6 will be implemented in the mobile phones  Separation of network layer into two sub-layers: (i) Lower network layer (for each interface) (ii) Upper network layer (for the mobile terminal)
  23. 23. 24Mobile Computing and Wireless Communication  Wireless network differs from wired network regarding the transport layer.  In all TCP versions the assumption is that lost segments are due to network congestion.  In wireless, the loss is due to higher bit error ratio in the radio interface.  5G mobile terminals have transport layer that is possible to be downloaded & installed – Open Transport Protocol (OTP).  Transport layer + Session layer = OTP
  24. 24. 25Mobile Computing and Wireless Communication  Provides intelligent QoS (Quality of Service) management over variety of networks.  Provides possibility for service quality testing & storage of measurement information in information database in the mobile terminal.  Select the best wireless connection for given services.  QoS parameters, such as, delay, losses, BW, reliability, will be stored in DB of 5G mobile.  Presentation layer + Application layer = Application
