  30. 31 Basic Architecture of 5G 5G Mobile Phone Concept
  31. 32 The 5G terminals will have software defined radios and modulation schemes as well as new error-control schemes that can be downloaded from the Internet. The development is seen towards the user terminals as a focus of the 5G mobile networks. The terminals will have access to different wireless technologies at the same time and the terminal should be able to combine different flows from different technologies. Basic Architecture of 5G
  32. 33 OSI Layers in the 5G Mobile Terminal Design
  33. PHYSICAL LAYER : Physical and Medium Access Control layers i.e. OSI layer 1 and OSI layer 2, define the wireless technology. For these two layers the 5G mobile networks is likely to be based on Open Wireless Architecture(OWA). NETWORK LAYER: • 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 • Separation of network layer into two sub-layers: (i) Lower network layer (for each interface) (ii) Upper network layer (for the mobile terminal)
  34. 35 • 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 • 5G mobile terminals have transport layer that is possible to be downloaded & installed – Open Transport Protocol (OTP) Open Transport Protocol (OTP): Application (service) Layer: Provides Quality of Service (QoS) QoS parameters, such as, delay, losses, BW, reliability, will be stored in DB of 5G mobile Presentation layer + Application layer = Application
  35. 36 Where we are....... On 12 May 2013, Samsung Electronics stated that they have developed the world's first "5G" system. The core technology has a maximum speed of tens of Gbit/s (gigabits per second). In testing, the transfer speeds for the “5G” network sent data at 1.056 Gbit/s to a distance of up to 2 kilometres.with the use of an 8*8 MIMO In July 2013, India and Israel have agreed to work jointly on development of fifth generation (5G) telecom technologies. On 1 October 2013, NTT (Nippon Telegraph and Telephone), the same company to launch world first 5G network in Japan, On 6 November 2013, Huawei announced plans to invest a minimum of $600 million into R&D for next generation 5G networks capable of speeds 100 times faster than modern LTE networks On 8 May 2014, NTT DoCoMo start testing 5G mobile networks with Alcatel Lucent, Ericsson, Fujitsu, NEC, Nokia and Samsung. At the end of September 2014, Dresden university inaugurates a 5G laboratory in partnership with Vodafone
  36. 37 5G Hardware Uses UWB (Ultra Wide Band) networks with higher BW at low energy levels BW is of 4000 Mbps, which is 400 times faster than today’s wireless networks Uses smart antenna
  37. UWB (Ultra Wide Band) Uwb is an advanced transmission technology that can be used in the implementation of 4G network . The secret to uwb is that it is typically detected as noise . This highly kind of noise does not cause interference with current radio frequency devices But it can be decoded by another device that recognizes uwb and can reassemble it back to a signal. It uses a frequency b/w 3.1 to 10.6 GHz. Uwb uses frequency from high to low. There by passing through objects like sea or layers of rocks , nevertheless because of the weakness of the signal
  38. Smart Antennas Multiple “smart antennas” can be employed to help find, tune, and turn up signal information. Since the antennas can both “listen” and “talk,” a smart antenna can send signals back in the same direction that they came from. This means that the antenna system cannot only hear many times louder, but can also respond more loudly and directly as well. There are two types of smart antennas:-
  39. 1.SWITCHED BEAM ANTENNA Switched beam systems have several available fixed beam patterns. A decision is made as to which beam to access, at given point in time, based up on the requirements of system. 2.ADAPTIVE ARRAY ANTENNA It represent the most advanced smart antenna approach to date using a variety of new signal processing algorithms to locate and track the user, minimize interference, and maximize intended signal reception.
