Transcript of "Deploying LTE Femtocells in Order to Achieve Coverage in Rural Areas"

  1. 1. Deploying LTE Femtocells in Order to Achieve Coverage in Rural Areas Arief Hamdani Gunawan
  2. 2. The Core Business As of June 30, 2009 :
  3. 3. Penetration in Telco Industry As of June 30, 2009 :
  4. 4. Agenda Deploying LTE Femtocells Achieving Coverage in Rural Areas •Optimizing •Traffic approach through Femto •Adoption of technologies •Deployment scenarios •Possibility •SAE capability for 700 MHz
  5. 5. Traffic Approach traffic •equipment capacity •optimistic traffic LTE urban •optimistic revenue HSPA+ / EV-DO Rev A/B •pessimistic traffic suburban HSPA / •pessimistic revenue EV-DO Rev A rural time The decouple of traffic and revenue is bigger in higher traffic
  6. 6. Different Deployment Scenarios for LTE Scenarios Today LTE Deployment Important Prerequisites: GSM GSM GSM to LTE LTE •Technology maturity •Demand 3G1X •Frequency allocation 3G 1X EV-DO Rev A/B 3G 1X LTE CDMA Pessimistic Scenario Optimistic Scenario to LTE Other: 3G 1X 3G 1X •Efficient EV-DO Rev A/B EV-DO Rev A LTE •Scalable GSM GSM GSM UMTS UMTS UMTS LTE W-CDMA Pessimistic Scenario Optimistic Scenario to LTE GSM GSM UMTS UMTS LTE The LTE introduction for wireless operator
  7. 7. The Right Time - Relative Adoption of Technologies 3.9G 3G 2G Rysavy Research projection based on historical data. Saturation of 2G < LTE Introduction Timing < Saturation of 3G (after 2010) (before 2020)
  8. 8. System Architecture Evolution 3GPP IP Access (HSPA, HSPA+) S3/S4 LTE / SAE S2 EUTRAN EPC S1 S2 non 3GPP WLAN 3GPP IP Access IP Access (EV-DO Rev A/B) The S2, S3, S4 interface enable SAE to provide flexibility
  9. 9. System Architecture Evolution Support to Achieve Coverage in Rural Areas 3GPP Suitable to support: IP Access Existing GSM/W-CDMA in rural areas (HSPA, HSPA+) LTE / SAE EUTRAN EPC Suitable to support: •(Optimizing) current wireline infrastructure •High reliability non 3GPP •New wireless deployment WLAN 3GPP IP Access IP Access (EV-DO Rev A/B) Suitable to support: Suitable to support: Existing CDMA in rural areas Existing GSM/W-CDMA in rural areas FEMTO, X2 interface, and SON architecture able to serve un-coverage area, remote area and isolated area
  10. 10. Why (Optimizing) current wireline infrastructure through Femto • Basic coverage: provide Femto as the main infrastructure in the ‘blank spot’. • Data coverage: provide Femto as the main infrastructure in the low speed area or no data area (ex: GSM only area), in fact the indoor is become more critical. • Capacity expansion: the ‘independent individual BTS’ able to reduce congestion in BTS. • User experience: provide xDSL experience in the home user/building user • Cost reduction: Reduce backhaul cost and maintenance

A Typical Femto Solution D’ AAA HLR ISP Network (ADSL) Uu Iu or CS/PS UE FAP SEGW FGW A/Gb CN IPsec tunnel Option 1 Option 2 Option 3 Service Network AAA = Authentication, Authorization, and Accounting CS/PS CN = Circuit Switch / Packet Switch Core Network FGW = Femto Gateway HLR = Home Location Register SeGW/Sec =GW Security Gateway UE = User Equipment IEEE Communications Magazine .

  14. 14. Frequency Allocation Candidate in UHF Band (470 – 806 MHz) • Current condition: – Capacity: 42 Analogue Channels (22 to 61). – Jakarta condition: 29 trans, 37 tpi, 39 tvri, 41 ivm, 43 rcti, 45 sctv, 47 antv, 49 dvnm 51 dlob, 53 latvm 57 metro, 31 tvri, 35 ivm, 27 spcet (Source: RANCANGAN KEBIJAKAN PENATAAN PITA FREKUENSI TV SIARAN UHF (470 – 806 MHz)) • Future approach: – 502 to 606 MHz: Band IV and V (lower): 16 channels (25 to 41) and bandwidth/channel 8 MHz for DVB-T free-to-air. – 606 to 806 MHz: Band V (upper) : 20 channels (42 to 62) and bandwidth/channel 8 MHz for mobile multimedia.
  15. 15. Achieving Digital Dividend for LTE Deployment • Fixed Broadcast – Modulation: 64 QAM and capacity: 48 Mbps. – High Definition TV (HDTV) : 4 programs – SDTV (per program 2 Mbps) : 24 programs – Audio content 64 kbps: 750 programs • Mobile Broadcast – Modulation: 16 QAM and capacity: 12 Mbps – SDTV: 8 programs • Time and license constraint: – Digital TV Trial – Analogue moratorium and simulcast – Analogue Phase Out • More to SDTV rather than HDTV. • More to frequency efficiency.
  16. 16. Closing Deploying LTE Femtocells to achieve coverage in rural areas • So, what is the main consideration to deploy LTE (in rural)? – Technology maturity • Why LTE Femtocells able to achieve coverage in rural areas – Through the X2 interface, LTE able to utilize existing wireless access / cellular infrastructure – Through the Femto interface, LTE able to optimize the infrastructure. FEMTO can be suitable for providing basic coverage, data coverage, capacity expansion, user experience and cost reduction. – FEMTO, X2 interface, and SON architecture able to serve un- coverage area, remote area and isolated area – Demand • The uncertainty of decouple in urban is higher rather than in rural. • The scalable solution of technology and/or the capability to optimize the current infrastructure might be important to serve in rural areas. – Frequency allocation • The digital dividend is very interesting for LTE deployment in many countries • The other considerations are efficiency and scalability
