5 Wireless Backhaul Fiber Backhaul Microwave Backhaul

6 Wireless Backhaul Alternatives Capacity (Mbps) 10,000 Fiber Capital intensive Limited availability Sourced from competitors 1, Microwave Radio Highly cost -effective Rapidly deployed No leasing conflict 10 Leased Line (Copper) Costly Sourced from competitors Distance (KM) Optimal Technology for Backhaul 6

7 Wireless Backhaul Alternatives Marconi s Radio (1907) 7

8 Wireless Backhaul Alternatives Microwave Links Cost a Fraction of the Cost of Trenching for Fiber Rural break-even Urban break-even Even Leasing fiber is too expensive In Greenfield mobile network, there is hardly any economic reason for fiber deployment 8

11 Market Trends & Challenges 6

12 Market growth drivers The next billion subscribers From Wikipedia: Between 50 to 100 million people in the world have mobile phones, even though they do not have electricity at home 12

13 Market growth drivers Explosion in mobile data Global mobile data traffic is nearly tripling every year Smart-phones 13% of handsets but 78% of global traffic. Mobile video traffic is over 50% of the world's mobile data traffic 1 3

14 Market Drivers Bandwidth Hunger is Ever Increasing Everything gets mobile - We expect wireline experience from the wireless networks Video Cloud Computing M-2-M Video applications are the key drivers From local to remote IT infrastructure M-2-M will hit $12B and 50B devices (HD, HD 3D) taking the office with you in 2020 x1000 traffic Mobile Data is Exploding Solid Connectivity Gbps Speed msec Latency 14

15 Operators Challenges Revenues & Traffic Decoupling Over The Top (OTT) Content Delivery Much more network traffic but less revenues Network that just moves bits is the hardest one to make money running 15

16 Technology Trends & Challenges - Capacity 14

17 Capacity Challenge 2012 LTE 150 Mbps 2018 LTE-A 1 Gbps * LTE 4G is the Long Term Evolution defined by 3GPP R8,9. requires a broadband state of mind 17

18 Mobile Access & Backhaul Capacity Access Technology UE Peak Rates Backhaul Required Rates per site 14.4Kbps 2G (90 s) 384Kbps 3G R4 (2002) 4Mbps 8Mbps Circuit Switching (PDH, SDH) 3.6Mbps 14.4Mbps 3G R5/6 HSPA (2005) 42Mbps 3G R7 Evolved HSPA (2008) 170Mbps 320Mbps 3G R8 LTE (2010) 10-20Mbps 20-50Mbps Mbps Packet Switching (Eth / IP) Access Technology Spectral Efficiency (bit/s) / Hz per link 320Mbps at 20MHz, 4x4 MIMO 3.5G and LTE bring huge spectrum utilization benefits in the Mobile access 18

19 Mobile Access & Backhaul Capacity How Microwave Backhaul can match access capacity needs High QAM Modulations From QPSK 256QAM to 512 / 1024 / 2048 QAM New spectrum allocation 32GHz, 42GHz, V/E-Band (60/70/80G) New channel bandwidth to 112MHz Nx250 MHz (E-band) Multi Carrier Radios 19

20 Mobile Access & Backhaul Capacity Point to Point Backhaul Spectral Efficiency (bit/s) / Hz per link X2 efficiency with XPIC Eth 1024 QAM XPIC STM1 28MHz Eth 256 QAM and beyond MW Spectral efficiency is continuously improved to match access needs 20

21 Efficient Use of Capacity Optimize Traffic Is it just me or, I am surrounded by headers Header Payload Header Payload CH Compressed Payload CH Compressed Payload CH = Compressed Header CH Compressed Payload CH Compressed Payload 21

22 Efficient Use of Capacity Improve Network utilization 22

23 Technology Trends & Challenges Evolving Infrastructure 22

24 Evolving Infrastructure Bandwidth explosion and increasing amount of users demands rethink of wireless networks and traditional technologies HETNET Small-Cells WiFi-Offload Y *CoMP Coordinated MultiPoint As defined by 3GPP LTE-Advanced. CoMP Cloud-RAN 24

25 Small cells I hear we can make it big in Telecoms

26 Small cells Urban core Overlay approach- Macro cell for voice & HSPA Small cell for high speed data Street level deployment Low cost, Plug and play Macro CoMP (3GPP R9) for efficient spectrum usage Non-technology hurdles to overcome for deployment! Small Cells Backhaul - Connect via Macro sites Any Topology Mix of backhaul technologies

27 Small Cells - Backhaul Challenge Near / Non LoS (<6G) No antenna alignment Low capacity E-Band (70-80G) High capacity Low interferences Licensed V-Band (60G) Very small form-fit Mid-High Capacity Low TCO but Unlicensed Multipoint Microwave (6-40G) Mid Capacity Licensed Large Antennas Fiber VDSL GPON Satellite Free Space Optics No single winning solution 27

28 Cloud RAN C-RAN RRH - Remote Radio Head BBU Base Band Unit Distributed approach for Small cells Sharing of processing resources between cells CoMP Coordinated MultiPoint C-RAN enables Network MIMO (Coherent TX/RX) RRH connects with CPRI (ORI) => Requires High rates & low latency CoMP with Coherent transmission / reception ( Network MIMO ) =>Requires high capacity meshed backhaul with tight timing and delay 28
