DRIVERS FOR PACKET LONG-HAUL:MARKET ENVIRONMENT

FIXED: DEMAND FOR HIGHER SPEED BROADBAND

• On-demand video and more devices driving residential demand

MOBILE: TRANSITION TO LTE/LTE-A IS UNDERWAY

• Higher capacity requirements in aggregation and backbone

• IP orientation of LTE driving shift to packet-optimized transport

4


• On-demand video and more devices driving residential demand

• Higher speed fixed access (PON, vectoring, bonding) moving bottleneck to backbone

TECHNOLOGY: PACKET EXCEEDS TDM/LEGACY TRAFFIC

• VoIP and emergence of VoLTE accelerating TDM decline

• Networks optimized for IP (not TDM) are driving efficiencies and reducing costs

DRIVERS FOR PACKET LONG-HAUL:MICROWAVE SPECIFICS

FASTER TIME-TO-MARKET

LOWER

• No heavy civil engineering work (trenching)• No complex permit requests• Easy to re-allocate equipment when traffic patterns change

• Flat deployment cost regardless of distance

Microwave vs. fiber

Transform to packet

5


CAPACITY AND LATENCY• MW provides enough capacity for today’s needs • MW offers a much lower latencyRELIABILITY • Better equipment reliability with very high MTBF• Link availability improved with advanced radio features

LOWER COST

GREAT PERFORMANCE

• Flat deployment cost regardless of distance• No recurring leasing or bandwidth charges• Easy maintenance, reducing OPEX

• Enough capacity for today’s (and tomorrow’s) needs

• Advanced radio equipment for reliability and high MTBF

• Microwave offers much lower latency

HOW TO DEFINE A LONG-HAUL PACKET MICROWAVE:CHARACTERISTICS

LEGACY

SERVICE CONVERGENCE• Transform services — the right way• One transport technology

CAPACITY SCALE• Packet and RF mechanisms toolset• Improved availability

PACKET

6


IMPROVED PERFORMANCE, HIGHER FLEXIBILITY, MORE SIMPLICITY

• Improved availability

OPERATIONAL EFFICIENCY• Provisioning based on b/s• Equipment simplification

MULTICHANNEL CAPABILITY

FULL-INDOOR APPROACH

THE MULTICHANNEL MODEL:EFFICIENT SCALING, PROTECTION

Efficient distribution of flow contents over the

N+0 bundle

PACKET FLOWS

One logical pipe whose total capacity is available to all services:

• Adaptive modulation-aware• Any channel frequency/width• Any polarization• Any modulation level

Multichannel N+0 link

7


Increased capacity and reliability over traditional

N+1 systems

SDH/SONET FLOWS

PDH FLOWS

Multichannel N+0 link

RELIABLY SCALE ALL SERVICES, INCREASE PROTECTION

THE FULL INDOOR APPROACH

Applicable to high-capacity systems• Split-mount also suitable if capacity <2–2.5 Gb/s

Equipment protected in case of difficult environmental conditions

Fully resilient and hardware protected• Easy upgradable, no traffic impact • Reduced maintenance cost, no need to climb on the tower and fewer people required

• Reduced out-of-service time

8


• Reduced out-of-service time

Single waveguide vs. many cables for connectivity to the antenna

Waveguide losses compensated by highest system gain
