Backhaul Trends PtP
 All outdoor radios (AOR)
 PtP
 Traditional frequency bands: 6 – 38 GHz.
 New “traditional” band: 42 GHz. Ethernet

 Unlicensed band: 60 GHz.
 Light-licensed band: 70 – 80 GHz (E-
band or millimeter wave) All-outdoor Radio

 PmP
 Traditional frequency bands: 2.3 -3.5GHz
 Unlicensed band: 5 GHz.
 Microwave band: 10.5, 26, 28 GHz


Backhaul Trends PmP

• PmP architecture lowers CAPEX for PtP and PmP
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 Maravedis PmP backhaul report
(PoPs) in urban and dense urban
areas in progress….

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 femto
derived 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

4. Ethernet priority

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


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

Agenda

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 Driving you to the
All-IP evolution !
Conclusion

2 A webinar designed exclusively for Maravedis

Changing the network is a complex process

1. Cost reduction 3. Functionality

 The introduction of new technology  Functionality should be added to
for a specific area of the network the network that is not currently
allows Operator to reduce the costs supported in the transport network
per bit transported  Point-to-Multipoint
 Point-to-Multipoint  IP radio
 Nodal Point-to-Point
 End-to-End Service Provisioning

4. End-of-Life

2. Capacity expansion  Hardware and software reaches the
end of their technical lifetime. This
 Systems that reach the limits of could mean that the system is just
their capacity should be replaced too old, but it could also mean that
 Adaptive Modulation the vendor has ended support for
 Payload compression the system.
 RLA, XPIC

 LTE triggers a multi-faceted modernization of backhaul networks


Cellular Architecture & Migration to LTE

Macro/Pico, Layered Cell Green-field Micro-Cell Network
Architecture Architecture in Urban Areas

 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

 Applicable for the Low RAN and High RAN
 Suitable for various applications
 Dedicated High Capacity per link


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
 Shared High Capacity per Base Station Sector


Unrestricted backhaul capacity using PMP
technology

 From 2 hub sites one can have 1.2Gbps of backhaul capacity


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)
VS.

Spectrum (4 Links):
 PMP: 28 MHz
 PtP: 28 - 56 MHz

PtP: Good for Flat Traffic
PMP: Ideal for Bursty LTE Traffic
