Convergence: The Merging of Wireless & Wireline Start from shared assets and work towards fully integrated systems

•  Densification of the wireless network & fixed broadband deployments

•  Leverage existing footprint and locations for multi-use, multi-service delivery

•  Plan and build wireless/wireline simultaneously

•  Common hardware for SDN/NFV •  Applications run on COTS •  Similar processes

•  Network functions converge •  Common credentials & policies •  Containerization

Efficiency, agility, scale, and time-to-market all improve when networks and systems are converged.

Converged Access Network Architecture Overview

•  Networks should to be designed and constructed keeping cost, flexibility and capacity in mind

•  Media installation is a cost driver, resulting in a parallelization to serialization conversion

•  Multiple Fibers

•  Multiple Wavelengths •  Converged Residential/Business/Mobile Services

•  Higher Data Rates

•  Resembles a small data center: power, cooling, cabling, COTS

•  Incorporates SDN, NFV, virtualization

•  Supports a smaller number of sectors •  Leverages existing sites – huts, shelters,

cabinets •  Increased requirements for power and fiber

Virtualization will lead to commoditized equipment, Centralization will also drive demand for flexibility in the physical layer, more fiber between the RRH & BBU, and different types of RRHs

RAN Fronthaul Transport Options

Microwave For situations where CPRI transport between RRH and BBU is required over short distances and fiber is not available, microwave transport is an attractive option.

+ Flexible Deployment + Cost effective - Bandwidth limited - Distance limited

Dedicated Fiber An attractive option for scenarios where an operator has a large installed base of available fiber. Also an option for scenarios where it is more cost effective to lease/install fiber than to deploy an optical transport element at the cell site. + Simplicity + Grey SFP’s - Large use of fiber - Cost prohibitive

Active Wavelength Based Systems Utilizing OTN for CPRI transport does require careful consideration as a number of the highly valuable features of OTN also add latency.

+ Use of Grey SFP’s + Enables rings & mesh - High Latency - Powering Requirements

Passive Wavelength Based Systems Passive WDM offers a good combination of characteristics for CPRI transport. In particular, CWDM supports low propagation delays and high data throughout. It is an economical choice, both in equipment costs and in its use of fiber resources. + Increases fiber capacity + No increase in latency - No native OAM - Coloured SFP’s needed

Passive Optical Network PON is a potentially attractive option for CPRI transport as it can provide access to an existing fiber plant located in high-traffic areas, where small cell deployment are most likely to occur.

+ Additional revenue stream + Access to fiber in high density

areas - Limited footprint - Coloured SFP’s needed

ALL FRONTHAUL OPTIONS WILL NEED TOBE CONSIDERED
