BWS includes three basic elements: Base-Band Unit (BBU), Digital Router Unit (DRU), Low Power Radio (LPR).
The units and their general functionality are described in the following table.

Description
BBU
This unit connects to the core-network provider’s
base station, receives the RF signals, and
distributes it towards BWS internal units.
It connects to an operator's Evolved Packet Core
(EPC) over the S1 interface. It connects to
Corning's family of digital remotes using the
Common Public Radio Interface (CPRI) through
the DRU.
DRU
A fully-digital radio routing platform, performing
distribution and routing of RF samples via CPRI
stream, providing signal processing while
minimizing power loss.
LPR
A digital radio remote unit, providing plug-and-
play processing.
LPR includes internal antennas, and supports the
following frequencies: 5 MHz, 10 MHz, 15 MHz,
20 MHz
Max coverage range for BWS 1.0: 5000 square
feet.
1.3.3
System Management Model
BWS internal configuration and management are done through two interfaces:
•
Through the BBU: using the BBU GUI application named: Spider Cloud Provisioning Service (SCPS)
•
Through DRU units: using the DRU GUI application.
Note: LPRs do not have direct management ports, and are each managed through the DRU unit
to which the LPR is physically connected.
The system includes a single management user (type admin), and only one management session may be
open at a time, to avoid conflicts, and provide better control of the system.
To manage the system, the user connects a computer to the management port of the relevant unit (DRU or
BBU), opens a session and updates the required parameters through the GUI, where:
•
BBU UI updates are done through the core network provider’s network.
•
DRU UI updates are performed directly through the DRU.
