Heterogeneous Networks Move Indoors

  1. 1. Heterogeneous Networks Move Indoors Martin Ljungberg, Product Mananger Small Cells Solutions
  2. 2. Application Coverage @ SMS 10 Mbps 1 Mbps 0.1 Mbps >10 Mbps PERFORMANCE DRIVES LOYALTY Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 2 Source: Ericsson Consumer Lab “Global network performance study 2013”
  3. 3. Mobile Networks in Enterprise › Bring your own device – Security: private devices connected via Internet › Workforce – Mobility: access company’s information from anywhere via Internet › Partners/Suppliers – Share: partners accessing company’s information via Internet Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 3 Mobile Broadband Internet available everywhere Cloud Centralized services delivery
  4. 4. 1 2 3 Indoor solutions do not meet future demand Today’s solutions are built mainly for coverage and voice Lack of deployment flexibility Not cost efficient to cover majority of building sizes Limited scalability Costly to add capacity, frequency and new technology e.g. LTE, MIMO Number of buildings The Indoor Challenge Building size ? Outside-in Pico No optimum solution DAS Source: Ericsson. Illustrative picture Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 4
  5. 5. Macro base station Architecture Antenna Radio Unit RF (3GPP) Digital Unit, Baseband CPRI Packet Backhaul Feeder RF power and Band defined by Radio Unit (RU) Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 5 Fiber Capacity defined by Digital Unit (DU), Baseband
  6. 6. Antenna Integrated Radio architecture Antenna and Radio Unit Digital Unit, Baseband CPRI Packet Backhaul Fiber RBS architecture optimized for high power RF performance Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 6
  7. 7. Radio Dot System Architecture Radio and Power CPRI Packet Backhaul CAT 5/6/7 Cable New architecture optimized for low power indoor configurations Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 7 Fiber
  8. 8. Comparing Complexity Radio Dot System … Typical Coax Based DAS Radio Dots (RD or Dots) … Active Power Amplifier – Not a Radio Unit Passive Antenna Indoor Radio Unit (IRU) Baseband/ Radio Digital Unit (DU) Interim - Passive Interface Module Fiber cable LAN cable (CAT5/6/7) Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 8 Feeder cable
  9. 9. Hitting the Sweet Spot Medium to Large Buildings Subtending nearby RBS DU and IRU centrally co-located with star configuration to Radio Dots DU baseband resources shared with nearby rooftop RBS or wall mount mRBS Common configuration for single tenant enterprise buildings Enables advanced LTE coordination between outdoor and indoor coverage Large to Very Large Buildings DU centrally located in the building IRU distributed to floor or building segment level Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 9 Campus or Large Venues Multiple installations cover multiple buildings or a large venue (university, enterprise campus, stadium) Centralized DU baseband can be shared among facilities, supporting expansions over time DU IRU Dot Fiber cable LAN cable (CAT5/6/7)
  10. 10. 100% Network Integrated › 3G and LTE outdoor and indoor networks evolve and grow in lockstep › Common processes and tools drive operational efficiencies › Network optimization benefits accrue to users wherever they are LTE Combined Cell High Order Modulation 3G soft handover VoLTE and HD voice FUNCTIONAL PARITY AND SYNCHRONIZED EVOLUTION ACROSS RADIO PORTFOLIO Interference management Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 10 Carrier Aggregation
  11. 11. Connecting the Dots Elegant, ultra compact and high capacity indoor small cell Quick and easy deployment 100% integrated with existing radio network Broadband World Forum 2013 | Ericsson AB | 2013-10-22 | Page 11
