5. 2. Existing Wireless Technologies
 3GPP(3rd Generation Partnership Project )
The 3rd Generation Partnership Project (3GPP) is a collaboration
between groups of telecommunications associations, known as the
Organizational Partners. The initial scope of 3GPP was to make a
globally applicable third-generation (3G) mobile phone system
specification based on evolved Global System for Mobile
Communications (GSM)
 HSPA(High Speed Packet Acess)
High Speed Packet Access (HSPA) is an amalgamation of
two mobile telephony protocols, High Speed Downlink Packet Access
(HSDPA) and High Speed Uplink Packet Access (HSUPA), that
extends and improves the performance of existing 3G mobile
telecommunication networks utilizing the WCDMA protocols.

Long-Term Evolution (LTE) is a standard for high-
speed wireless communication for mobile phones and data terminals. It
is based on the GSM/EDGE and UMTS/HSPA network technologies
 Wi-Fi(Wireless Fidelity)
Wi-Fi (Wireless Fidelity) is a generic term that refers to IEEE 802.11
standard for Wireless Local Area Networks (WLANs).
 Li-Fi(Light Fidelity)
Li-Fi(Light Fidelity) basically the sending of the digital signals via
light. if Li-Fi technology can be put into practical use, every bulb can
be used as an alternative to Wi-Fi hotspots

15. What is 5G Technology?
 For the consumer it will mean ultra high data speeds (upwards of
20GBPs), ultra low latency, and new devices and form factors.
 The 5G technology is expected to provide a new (much wider than
the previous one) frequency bands along with the wider spectral
bandwidth per frequency channel. As of now, the predecessors
(generations) mobile technologies have evidenced substantial
increase in peak bitrate.
 it is able to support the speed up to 10 Gbps.

16. 4. 5G - Architecture
 Architecture of 5G is highly advanced, its network elements and
various terminals are characteristically upgraded to afford a new
situation. Likewise, service providers can implement the advance
technology to adopt the value-added services easily.
 However, upgradeability is based upon cognitive radio technology
that includes various significant features such as ability of devices
to identify their geographical location as well as weather,
temperature, etc.
16

17. Cont..
 Cognitive radio technology acts as a transceiver (beam) that
perceptively can catch and respond radio signals in its operating
environment. Further, it promptly distinguishes the changes in its
environment and hence respond accordingly to provide
uninterrupted quality service.

number of independent and autonomous radio access
technologies. Each of the radio technologies is considered as
the IP link for the outside internet world.
 The IP technology is designed exclusively to ensure sufficient
control data for appropriate routing of IP packets related to a
certain application connections.

20. Open Wireless Architecture
(OWA)
 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
20

21. 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
 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)
21

22. Open Transport Protocol (OTP)
 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
22

23. Application (service) Layer

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

going on.
 The speed, this technology is claiming seems difficult to achieve
(in future, it might be) because of the incompetent technological
support in most parts of the world.
 Many of the old devices would not be competent to 5G, hence, all
of them need to be replaced with new one expensive deal.
