Backhaul Trends PtP All outdoor radios (AOR)
PtP Traditional frequency bands: 6 – 38 GHz. New “traditional” band: 42 GHz. Unlicensed band: 60 GHz. Light-licensed band: 70 – 80 GHz (E-
band or millimeter wave)
PmP Traditional frequency bands: 2.3 -3.5GHz Unlicensed band: 5 GHz. Microwave band: 10.5, 26, 28 GHz
All-outdoor Radio
Ethernet

Backhaul Trends PmP
PtP and PmP• PmP architecture lowers CAPEX for both access and backhaul
• PmP will grow mostly in the urban regions, lots of testing in cities
• Optimum backhaul solution for aggregation Points of Presence (PoPs) in urban and dense urban areas

Small Cells Trends Reachability is the key - driving solutions
closer to the consumer
Macro derived pico cells are more expensive, larger format, and have higher power consumption than femtoderived metro cells.
High capacity – up to 1 Gbps
Low cost (CAPEX & OPEX)
Short deployment lead time
From macro and micro to pico, femto
indoor or outdoor serving different needs

Challenges for backhaul vendors
Quick and simple site deployment
Compliance with SLAs and technical requirements
Focus on continuous service availability
Cost effective solutions
QoS and monitoring – effective links management is required

Microwave Market Overview
BROADBAND WIRELESS INTELLIGENCEwww.maravedis-bwa.com © Copyright All Rights Reserved 2011 Maravedis Inc.
Summary Vendors requirements and operator needs will help the
microwave and other backhaul technologies meet its challenges
PtP vs PmP will still be a challenge for some operators
Some validation still needs to be done to meet operators’ requirements, especially on PmP or coexistence with PtP
LTE network’s capacity, reliability, speed will depend on mobile backhaul

Driving you to the
All-IP evolution !
Designing in and out of the box
Transmission challenges and drivers for
architectural changes
Options, architectures and alternatives
Design examples, unconventional
approaches, benefits and savings

2. Capacity expansion
Systems that reach the limits of
their capacity should be replaced
Adaptive Modulation
Payload compression
RLA, XPIC
3. Functionality
Functionality should be added to
the network that is not currently
supported in the transport network
Point-to-Multipoint
IP radio
4. End-of-Life
Hardware and software reaches the
end of their technical lifetime. This
could mean that the system is just
too old, but it could also mean that
the vendor has ended support for
the system.
1. Cost reduction
The introduction of new technology
for a specific area of the network
allows Operator to reduce the costs
per bit transported
Point-to-Multipoint
Nodal Point-to-Point
End-to-End Service Provisioning
LTE triggers a multi-faceted modernization of backhaul networks
Changing the network is a complex process
A webinar designed exclusively for Maravedis
Cellular Architecture & Migration to LTE
The main path to the LTE era is to extend the existing GSM/CDMA networks of macro-cell structure with an
underlay network of micro/pico cells
Independently of the network migration path, the need to deploy additional equipment in various form factors
(macro/micro/pico LTE base stations) to increase capacity is a reality
Independently of the selected LTE network deployment approach, a need for extended backhaul connectivity in
distributed locations arises

Designing out of the box: use Point to MultiPoint
Applicable for the Low RAN transport
Best fit for high Peak to Average traffic ratio
Advantageous over Point to Point for edge backhauling
Low CAPEX/OPEX: Less equipment leads to less initial and running
costs
Rapid Deployment: Only add Terminals at customer premises
Ethernet Functionality: Advanced features and QoS guarantees end-
user SLAs
Legacy Support: E1 for legacy routing / switching CPE

Unrestricted backhaul capacity using PMP
technology

From 2 hub sites one can have 1.2Gbps of backhaul capacity
A webinar designed exclusively for Maravedis
Using inherent instability to create a stable
network
Adaptive modulation makes use of excess fade margin when not needed, to increase the link
capacity
Multiple links flows share a common, wide-bandwidth pipe
The maximum rate required by any one link is seldom used, other links may use it on demand
System bandwidth is not allocated permanently to each link, but only as required

PtMP vs. PtP: Connecting Two Points

Radio Performance (Link Equivalent):
PMP: 38 Mbit/s (4 TS), 155 Mbit/s (Peak)
PTP: (7MHz, 256 QAM): 50 Mbit/s (Flat)
PTP: (14MHz, 256 QAM): 100 Mbit/s (Flat)
PTP: (28MHz, 256 QAM): 200 Mbit/s (Flat)
Spectrum (4 Links):
PMP: 28 MHz
PtP: 28 - 56 MHz
VS.
PtP: Good for Flat Traffic
PMP: Ideal for Bursty LTE Traffic
