1 C-RAN: A New Perspective on Mobile Network Infrastructure to Address Todays Connectivity Challenges and Exploding Mobile Traffic Growth

2 Agenda Introduction Mobile Wireless Growth and Densification Mobile Network Evolution C-RAN & Base Station Hotels Fronthaul Network What is it? Closing

3 The Data Storm Exponential mobile data growth is driving the need for densification of the mobile network. o Global Mobile Data grew by 69% in 2014* o Projected data growth from 2.5 exabytes/month in 2014 to 24.3 exabytes / month in 2019 o 7.4B mobile devices by YE 2014 o Average smartphone will consume 4GB of traffic by 2019, up from 819MB in 2014 o New spectrum is scarce, costly and subject to long regulatory delays

4 Network Densification This becomes This High Power Macro Site DAS Small Cells RRH - cwifi 4

5 Mobile Networks Today Outdoor DAS In-Building DAS Split Macro Base Band Unit (BBU) at tower or rooftop is connected to Remote Radio Head with fiber C O A X Cell Site Cabinet Base Station Small Cell Backhaul Network Head End / Equipment Room Base Station Cell Site Cabinet Base Band Unit (BBU) Distributed Base Station Model 6 R R H R R H R R H F I B E R

6 Next Gen Mobile Network C-RAN Architecture Moves parts of the mobile network control function from the cell site to deeper in the network - Base Station Hotel. Introduces a new transmission network into the overall mobile network infrastructure Mobile Fronthaul. 8

7 C-RAN Today - Centralized Centralized RAN Benefits Speed-to-Market Ready to go Head-End Space Economies of Scale Less of Everything Shared hard-infrastructure - space, power, cooling, security Aggregated backhaul Less energy consumed Centralized dispatch, maintenance & sparing 7

8 BTS Hotels for odas Centralized Base Stations connected to Outdoor DAS Remotes with metro fronthaul fiber Old news! Base Station Hotel Base Station 1 Base Station n METRO FRONTHAUL FIBER 9

9 BTS Hotels for idas? Centralized Base Stations connected to Indoor DAS Remotes with metro fronthaul fiber Why not? Base Station Hotel Base Station 1 Base Station N METRO FRONTHAUL FIBER 9

10 BTS Hotels for Macro Sites? Base Band Unit at base station hotel connected to Remote Radio Head with metro fronthaul fiber Why not? D-RoF RRH RRH RRH Up to 10km for LTE Base Station Hotel Base Station 1 Base Station N Backhaul Network METRO FRONTHAUL FIBER 9

11 C-RAN Tomorrow - Cloud Cloud RAN Benefits Base station resource pooling On-Demand resource allocation Dynamic resource sharing & resiliency Virtualized software definable and tunable architecture Lower cost general purpose hardware 11

12 Cloud-RAN Scalability RRH RRH RRH D-RoF RRH RRH RRH Cell Site Cabinet D-RoF D-RoF RRH RRH RRH Cell Site Cabinet Cell Site Cabinet D-RoF D-RoF optical distribution network D-RoF Central Office Load Balancing Base-band Pool BBU System Module X2 Virtual BS Cluster Virtual BS Cluster IP/MPLS Network Virtual BS Cluster Fronthaul Load balancer & Switch Load balancer & Switch Optical Transmission Network 12

13 C-RAN Fiber Challenge Placing antennas close to users wherever they are and moving new protocols: Fiber Availability (Legacy Networks will Break) o Antennas Everywhere = Any-Pair-Anywhere o Capacity o Access New Protocols (capacity, latency, management) o Digital Radio over Fiber (CPRI, OBSAI) o High Bandwidth 600 Mb/s to 10Gb/s Capacity o Near Zero Jitter & Bit Error Rate o Low Latency < 100 µs 15

14 C-RAN Fiber Opportunity New Network Architecture needs to be deployed... A Network of Neighborhood Networks Neighborhood Networks - Fronthaul Distributed Neighborhood Colo Resilient Core Network - Backhaul

15 Closing - ZenFi Launched in 2014 to support the C-Ran evolution in the New York Metro Area New type of network designed to support densification requirements of C-RAN Critical barrier to C-RAN on today s infrastructure: Current networks weren t built to support the fragmentation and access that the transition to C-RAN requires The ZenFi network is built for access anywhere 15
