Chapter 1: Introduction
Cambium’s PTP 820S represents a new generation of radio technology, capable of high bit rates
and longer reach, and suitable for diverse deployment scenarios.
PTP 820S supports cutting edge capacity-boosting techniques, such as QPSK to 2048 QAM and
Header De-Duplication, to offer a high capacity solution for every network topology and every site
configuration. Its green, compact, all-outdoor configuration makes PTP 820S ideal for any location.
This chapter includes:
•Product Overview
•Unique PTP 820S Feature Set
•System Configurations
Page 1-1

Chapter 1: Introduction Product Overview
Product Overview
Delivering ultra-high capacity in any licensed band (6-38 GHz) PTP 820S provides a new level of
wireless capacity in current and emerging backhaul scenarios. PTP 820S combines a compact, all-
outdoor design, QPSK to 2048 QAM modulation, and an advanced feature set for Carrier Ethernet
Transport that includes a sophisticated Ethernet services engine, cutting-edge header de-
duplication techniques, frame cut-through, and more, to provide a compact and efficient solution
for a wide variety of cost-effective deployment scenarios including macrocell backhaul, small-cell
aggregation and emerging front haul applications.
PTP 820S is easily and quickly deployable compared with fiber, enabling operators to achieve
faster time to new revenue streams, lower total cost of ownership, and long-term peace of mind.
PTP 820S is an integral part of the family of high-capacity wireless backhaul products. Together,
the product series provides a wide variety of backhaul solutions that can be used separately or
combined to form integrated backhaul networks or network segments.
The series “pay-as-you-go” licensing model further enables operators to build for the future by
adding capacity and functionality over time to meet the needs of network growth without requiring
additional hardware.
