The evolution of mobile networks to 4G technologies, and primarily LTE, sets additional requirements and challenges for operator backhaul networks. The selection of flexible and future-proof microwave backhaul technologies is of paramount importance. Maravedis and Intracom wireless experts present critical trends in backhaul technologies and markets.

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

6. 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….

7. 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

11. 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

13. 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
