Backhaul Considerations
• 100 Mbps no longer sufficient
• Frequency options a must
• Shared spectrum makes
efficiency critical
• 802.11ac channel sizes create
deployment challenges
Cambium Has The Backhaul Solution To Meet The Most Demanding Requirements

On To Access…
Challenge
Impact
Solution
Spectrum Availability
Limits service level offerings, number of
AP’s/Subs, creates churn
PMP450 is available in 2.x, 3.x, 5.x
(licensed/unlicensed/defined use)
today!
Capacity (UL/DL)
Limits service level offerings, user
experience, Video
Proven canopy architecture results in no
performance degradation with distance
or increase in subscriber modules
Frequency Re-use
Inconsistent performance as subscriber
count increases. More channels to serve
same # of users
GPS Sync allows for frequency re-use.
Access spectrum is WISP’s most valuable
asset!
Finding balance between
propagation/capacity needs
Increased AP’s/Backhaul needed to add
capacity down the road (cellular
migration from high site design to small
cell model…CAPACITY DRIVEN)
Cambium delivering 900 MHz and micro
pop solution (Lite AP) with advanced
filtering to achieve capacity
improvements. Frequency options
unmatched by standards based solutions.
Back end complexity and
cost for competitive
solutions
SW maintenance costs increase along
with costs to administer complex core
solutions
PMP450 was developed for WISPs not
mobile operators with huge OPEX
budgets. (Cambium to offer tiered pricing
with AP Lite)
Customers aren’t served with buzzwords… but with secure, reliable, cost effective networks

The Power Of Frequency Reuse
Synchronization allows
frequency re-use!
– 6 sectors: select three nonoverlapping frequencies for
AP clusters

Competitive systems require
more AP towers to be added to
meet demand – resulting in
additional interference.
Frequency Reuse is the key to building scalable, reliable networks to your customers

Utilizing PMP 450i architecture
Employing Superheterodyne channel isolation
Maximize Spectral efficiency

Using GPS timing and colocation with PMP 100 900 MHz
• Product Design Goal
–
–
–
Under similar RF conditions (i.e. high noise floor, other operating equipment in the
band, etc.), PMP 450 900 MHz is expected to provide 3 to 4 times the AP capacity
as PMP 100 900 MHz, using similar channel size
In other words, deploying 7 MHz channels, you can replace PMP 100 900 MHz and
go from 4 Mbps capacity to 12-16 Mbps capacity
Given clean spectrum, PMP 450 900 MHz can provide 40+ Mbps per sector
