3. 4th Generation (4G)
DatarateDownload- 3Gbps,Upload -1.6 Mbps for LTE-Aand 100-200 Mbps Mobile Wi-
MAX
AccessTechnology:LongTerm Evolution Advanced (LTE-A),Wi-MAX(Worldwide
Interoperability for MicrowaveAccess)
FrequencyBand:1.8-2.6GHz
Bandwidth:1.4-20MHz
Switchingtechnology:Packet Switching
Application:Voice and Data +Video calling, Multimedia
Messaging Service (MMS), Digital Video Broadcasting etc.

4. 4G Architecture

5. 4G Advantages
Reduceddelays for both connectionestablishmentand transmission latency.
Increased user DataThroughput.
Increased celledgebit rate.
Reducedcostper bit implying improved spectralefficiency.
Simplified networkarchitecture.
SeamlessMobility including between different Radioaccesstechnology.
Reasonablepowerconsumptionfor the mobile device.
It provides integratedsecurityservices.

10. Why move to 5G????
At present, 4Gis latencyup to 40ms and 60ms, which is low-latencybut not enoughto
provide real-time response.5G’s prospective ultra-low-latency could range between 1msand
10ms.
Userincreasein exponentially
More network coveragehigher
available spectrum
Datarate,frequencyband
More securethen 4G
UninterruptedServices

11. Type 4G 5G
Data Rate Data rate Download - 3Gbps,Upload

(BDMA) and Non-and quasi-
orthogonal or Filter Bank multi-
carrier (FBMC)multiple access.
Frequency Band 1.8-2.6GHz 1.8-2.6GHz and 30-
300GHz.(expected)

12. Specs!

13. Physical layer Infrastructure / Short-Term Learning Technologies
• 5G NOMA
• NFV/Network Slicing
• 5-NR
• mMC (Massive Machine type Communication)
• Active User Detection
• PRACH (Physical random Access channel)

14. Conclusion
• 5G standards are still under development within 3GPP
• Final technical contributions for the initial 5G standards are being
discussed (Release 15)
• 5G will support enhanced Mobile Broadband (eMBB), Ultra-
Reliable and Low Latency Communications (URLLC) and massive
Machine Type Communications (mMTC)
• 5G RAN will be different from previous iteration of C-RAN and
D-RAN
• NGFI will likely be implemented for 5G and eLTE - exact
functional splits tbd
• There is significant complexity to manage in the core network,
including inter-working with and migration to NGCN
• BT is pro-actively developing 5G solutions…
