As the data capacity demand on mobile phone and other wireless operator networks booms, their telecom backbones, or backhaul infrastructures, have struggled to keep pace. To get high volumes of data from coast to coast, operators have in more recent times relied on fiber optic technology for their voice and data traffic. However, for these long-haul operations, fiber lacks practicality, flexibility, cost effectiveness, security and quick time-to-market. Increasingly, operators are turning to the original long-haul telco solution to meet all these needs: microwave radio.

7. AVIAT NETWORKS
In many cases fiber is
just not an option:
 Too expensive
 Not practical
 Too vulnerable

Long Haul, or
Trunking Microwave
has formed the
backbone of
networks around the
world.

HIGH CAPACITY, GUARANTEED
• Multi-channel microwave systems are
key for providing guaranteed high
capacity links for long-haul and
aggregation applications
• New techniques can help, but don’t fit
the application:
• Higher modulations >1KQAM
• MIMO
• Ethernet Optimization, eg: Header
Compression, etc
• Asymmetric links

ALL-INDOOR TRUNK RADIOS
• All-indoor trunking radios were originally
designed for N+1 SDH applications
• Supported features generally lag the rest
of the microwave market by >12 months
• Consist of a full equipment rack, with
additional clearance needed for
waveguide connections
• Connected to antenna(s) by semi-rigid,
elliptical waveguide – requires
pressurization, dehydration and regular
maintenance

BEASTS…

18. AVIAT NETWORKS
SPLIT-MOUNT ACCESS RADIOS
• Split-mount access radios can be used
for high capacity applications
• Usually much more cost effective than
indoor trunking radios
• Compact indoor unit, suitable for
installation in outdoor cabinet
• Simple coax IDU-ODU connection
• However, combining multiple channels
using couplers introduces significant
path losses

SPLIT-MOUNT TRUNKING RADIOS
• Combines the best of both worlds
• Environmentally sealed OBU, containing
channel-specific filters and branching
• Low-loss combining of 4x ODUs onto a
single- or dual-polarized antenna
• Mounted close to antenna – no
waveguide loss
• No pressurization needed
• ODUs easily removed and replaced for
maintenance

OUTSOURCING/SHARING
• Network outsourcing or
sharing becoming common for
operators seeking to reduce
costs and focus operations
• Active - spectrum, switches,
antenna, etc
• Passive - tower, shelter,
power supply, batteries,

• Backhaul – leased capacity
(over fiber and/or microwave)
