1Product Overview
1.1 Introduction
This manual is written to help service personnel understand and install the
Sercomm P208 (P208-TP or P208-OP) Citizen Broadband Radio Service
(CBRS) outdoor Small Cell. This first section gives a full product description
and a block diagram. The remaining sections provide component
identification diagrams, installation instructions, and specifications.
1.2 General Description
This Small Cell is a PoE++ power device that receives power around 30W
from a PoE power source equipment through all four fairs of Ethernet. The
device operates at CBRS band or LTE band 48. Its operating frequency
range is from 3550MHz to 3700MHz. The device supports 2x2 MIMO and
has 6W EIRP. The antennae of device is embedded. The backhaul of the
Small Cell is Ethernet.
The device can be managed or monitored by Bluetooth or a HeMS server .
1.3 Housing
A rugged die cast aluminum on the bottom of the housing is designed. The
device has wireless antennae and aluminum or metal will block wireless
transceiver. Externally, the housing base has installation mounts, a
ventilation valve, a connector, a grounding bolt:
• A weather-tight RJ45 jack for connection from a PoE source equipment
device to provide power and backhaul to the Small Cell.
• A waterproof, dustproof ventilation valve. Its purpose is to prevent invasive
moisture, dust and other chemical crystals from entering electronics,
electrical equipment and applies the characteristic of the highly
microporous PTFE membrane to expel pressure generated by moisture
and excess heat, to avoid too large internal pressure aggregation to
damage seal housing and internal electronic components, thereby extend
the life of equipment.
The valve is setup completed before shipping. Don’t have to do anything in
