1 ISEM 3410 Telecommunications and Networking Group Chan Chun Yin Choi Man Hei Wong Wai Mei MOBILE NETWORKING SYSTEM

2 Agenda 1. Mobile usage phenomena 2. Mobile networking system concept 3. Case: Yahoo! HK 4. Transformation from 1G to 4G 5. Advantage of 3G/4G 6. Disadvantage of 3G/4G 7. Application 8. Future expectation ISEM 3410 Telecommunications and Networking 2

3 1. Mobile usage phenomena (1/4) Asia – World leader Mobile data consumption = 659 MB/month up by 10% in the last 6 months North America Internet data usage is up by 120% Europe YouTube represents more than 20% of peak period downstream traffic on mobile networks ISEM 3410 Telecommunications and Networking 3

4 4 1. Mobile usage phenomena (2/4) Phone checking >6 per hour <18: 58% 18-30: 52% 31-40: 45% Phone purpose Whatsapp: 35%

5 ISEM 3410 Telecommunications and Networking 5 1. Mobile usage phenomena (3/4) Whatsapp trend makes people feel uncomfortable without phones. Checking phones >30 times even in washroom

6 Interesting Fact (4/4) 87% American adults who own a cell phone 84% Cell phone owners who could not go a single day without their device 81% Growth of smartphone usage in % Growth of global mobile data traffic in % Traffic on mobile devices from video in % American adults who own a smartphone 44% Cell phone owners who have slept with their phone nearby because they didnt want to miss a notification ISEM 3410 Telecommunications and Networking 6

7 7 2. Mobile networking system concept (1/2) Mobile phone = portable telephone receives or makes calls through a cell site/base station/transmitting tower. Digital cellular technologies: Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), cdmaOne, CDMA2000, Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/TDMA), Integrated Digital Enhanced Network (iDEN). Cell phone = Mobile phone Cell - Radio frequencies = limited, shared resource. Achieve both coverage and capacity for their subscribers Cell site range: ~ ½ mile, (Rural areas ~5 miles) Satellite phones

8 ISEM 3410 Telecommunications and Networking 8 2. Mobile networking system concept – Structure (2/2) A network of radio base stations forming the base station subsystem. The core circuit switched network for handling voice calls and text A packet switched network for handling mobile data The public switched telephone network to connect subscribers to the wider telephony network This network is the foundation of the GSM system network. There are many functions that are performed by this network in order to make sure customers get the desired service including mobility management, registration, call set up, and handover. Any phone connects to the network via an RBS (Radio Base Station) at a corner of the corresponding cell which in turn connects to the Mobile switching center (MSC). The MSC provides a connection to the public switched telephone network (PSTN). The link from a phone to the RBS is called an uplink while the other way is termed downlink. Radio channels effectively use the transmission medium through the use of the following multiplexing & access schemes: frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), and space division multiple access (SDMA).

9 ISEM 3410 Telecommunications and Networking 9 3. Case: Yahoo!HK (1/2) Working at Yahoo!HK Enjoy free smartphone Can choose any kind of smartphone and Yahoo!HK is responsible for the bill

10 ISEM 3410 Telecommunications and Networking Case: Yahoo!HK (2/2) Why Yahoo!HK is offer smartphones to employee? Yahoo!HK is developing the Mobile Platform Experience as an end user in order to know more what they really need 24 hours on call (No excuse not receiving calls/ s )

11 4. Transformation from 1G to 4G (1/6) 1st Generation AMPS (Advanced Mobile Phone Service) analog signals + dynamically assigned channels Limitations: no support for encryption, poor sound quality inefficient use of the spectrum ISEM 3410 Telecommunications and Networking 11

12 4. Transformation from 1G to 4G (2/6) 2nd Generation Referred as PCS (Personal Communication Systems) 2G technologies can be divided into: Time Division Multiple Access (TDMA)-basedTime Division Multiple Access Code Division Multiple Access (CDMA)-basedCode Division Multiple Access The main 2G standards: GSM(Global System for Mobile Communications) CDMA NA-TDMA(North American TDMA) D-AMPS(digital AMPS) ISEM 3410 Telecommunications and Networking 12

13 4. Transformation from 1G to 4G(3/6) 2.5th Generation 2G-systems implemented a packet-switched domain + circuit-switched domain 2.5G technologies: -High Speed circuit switched data (HSCSD) -General packet Radio Service (GPRS), -Enhanced Data Rate for GSM Evolution (EDGE) used for WAP, SMS & MMS services, Internet access ISEM 3410 Telecommunications and Networking 13

14 4. Transformation from 1G to 4G (4/6) 3 rd Generation Main technologies: UMTS (Universal Mobile Telecommunications System) – also called Wideband CDMA In the US, CDMA2000 In China Time Division-Synchronous Code Division Multiple Access (TD-SCDMA). ISEM 3410 Telecommunications and Networking 14

15 4. Transformation from 1G to 4G (5/6) 4 th Generation two technologies are supposed to be the based features of 4G:features of 4G WiMAX WiMAX stands for Worldwide Interoperability of Microwave Access previously worked as fixed wireless facility under the e band. Now the modified standard m has been developed with the properties of speed, wide spectrum, and increase band. ISEM 3410 Telecommunications and Networking 15

16 4. Transformation from 1G to 4G (6/6) LTE Advanced IMT-Advanced standard, formally submitted by the 3GPP organization to3GPP target is to reach and surpass the ITU requirements. an enhancement to LTE. improvement on the existing LTE network ISEM 3410 Telecommunications and Networking 16

17 5. Advantages of Cellular Networks (1/1) flexible enough to use the features and functions of almost all public and private networks increased capacity reduced power use larger coverage area reduced interference from other signals ISEM 3410 Telecommunications and Networking 17

18 6. Limitations Of Cellular Networks (1/1) o Wireless Access Medium o Limited Bandwidth o System Complexity o Limited Power o Limited Processing Power o Relatively Unreliable Network Connection ISEM 3410 Telecommunications and Networking 18

19 8. Future expectation 8. Future expectation (1/6) ISEM 3410 Telecommunications and Networking 19

20 ISEM 3410 Telecommunications and Networking Future expectation (2/6)

21 ISEM 3410 Telecommunications and Networking Future expectation - 5G Technology (3/6) 5th Generation Mobile technology Use cell phones within very high bandwidth All type of advanced features which makes 5G mobile technology most powerful and in huge demand in near future

22 ISEM 3410 Telecommunications and Networking Future expectation - Feature of 5G (4/6) High resolution for crazy cell phone user and bi- directional large bandwidth shaping. The advanced billing interfaces more attractive and effective. Providing subscriber supervision tools for fast action. Avoid error Large broadcasting of data in Gigabit which supporting almost 65,000 connections. Transporter class gateway with unparalleled consistency.

23 ISEM 3410 Telecommunications and Networking Future expectation - Feature of 5G (5/6) The traffic statistics more accurate. Remote management a user can get better and fast solution. Remote diagnostics also a great feature of 5G technology. Providing up to 25 Mbps connectivity speed. Support virtual private network. All delivery service out of business prospect The uploading and downloading speed of 5G technology touching the peak. Offering enhanced and available connectivity just about the world

24 ISEM 3410 Telecommunications and Networking Future expectation - Feature of 5G (5/6) Application to Yahoo!HK Main purpose: Interconnection between employers and employees Application to general public: Main purpose: Whatsapp If they could have used a faster, safer networking system, things would have gone even better.
