Introduction

Corning’s BWS™ platform 1.0 is the first fully-digital, end-to-end in-building cellular solution, for medium size venues. It provides coverage of 200,000 – 500,000 square feet, of mobile communication voice and data traffic, covering a wide range of frequencies. Being a pure digital system dramatically reduces system costs, and the system foot print.

Corning’s Low Power Remote (LPR) units are the end-point antennas connected by optical cable to the BWS system Digital Router Unit (DRU) (distribution/routing of RF samples via CPRI stream), and to the system Power Supply Unit (PSU) for power. The LPR units are installed underneath the frame of the acoustic or drop ceiling. LPR units provide plug-and-play, cost- effective processing while minimizing power loss and noise.

This chapter provides an overview of LPR interfaces, management and usage.

Overview: about BWS 1.0 Architecture

BWS fully digital platform incorporates integrated capacity source Enterprise Base Band Units (EBBU) with the digital distribution units – Digital Router Unit (DRU) and Low Power Remote (LPR) units. The solution enables multi band and multi operator support, high scalability (both, in capacity and coverage) and provides simple migration paths to future technologies. BWS 1.0 supports:

EBBUs: Up to four high capacity sources per DRU
LPR (Remotes): Up to 32 low power units per DRU
DRUs: Up to four DRUs connected per EBBU
Synchronization: 10 MHz clock domain

Architecture and Interfaces

BWS system connects externally, through the EBBU, towards Core Network Providers’ Evolved Packet Core (EPC), over the S1 interface.

Internally, the BWS units are connected via Common Public Radio Interface (CPRI) lines.

The system internal configuration and management allows user access flexibility, and is done through EBBU and DRU units, according to the needs.

The following figure shows an example of the system’s internal and external connectivity.

System Sub-Units

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

Unit Name| Picture|

Description

---|---|---

EBBU

| Sub-Units | 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

|

_ Sub-Units _

| A fully-digital radio routing platform, performing distribution and routing of RF samples via CPRI stream, providing signal processing while minimizing power loss.

LPR

| Sub-Units | 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.

Table 3: BWS Basic Units

System Management Model

BWS internal configuration and management are done through two interfaces:

Through the EBBU: using the EBBU 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 EBBU), opens a session and updates the required parameters through the GUI, where:

EBBU UI updates are done through the core network provider’s network.
DRU UI updates are performed directly through the DRU.

Two basic management states are distinguished:

Connectivity updates: includes first time deployment and provisioning, connectivity changes. For these use cases, the EBBU calculates and distributes system schemes and maps to the connected DRUs. The first-time provisioning includes:

Entering the EBBU data into:
The provider’s network
The EBBU itself (via SCPS application)
The EBBU initiates an identification procedure of its MAC address.

As a result, the EBBU and the network “know” how to communicate.

On-going updates: includes SW management, parameter settings, alarm monitoring etc. These actions are performed via the DRU.

Note: the system management has a single user, of type Admin. Only one management session may be active at a time.

The following figure shows the system management points.

Route the Cables

Connect the Cables

Power: Connect the DC wire pair (48V) to the LPR connectors panel, via the DC power adapter (terminal block connector).
Optic cable:
- Remove the rubber stopper from the SFP connector located in the LPR RF port
- Connect the optic cable to the LPR optic connector.
LEDs: Verify the power and link LEDs are lit green.

Verify Normal Operation

Verify the status LED blinking in green.

Verify CPRI link behaviour:

If there is a CPRI link – the green LED above the SFP will light.
If the optical cable is connected but the CPRI link was not established yet – the green and the amber LEDs will light together.

Post Installation Steps

After installing connecting and powering-on the LPRs, configure the LPR via the DRU connected to that specific LPR. Refer to the system UM for configuration and management needs.

Unit Management

To configure and manage the LPR and DRU units, the user needs to access the relevant DRU unit to which the LPR is physically connected. Another option is to access the overall system management mechanism, through the EBBU (refer to EBBU UM).

The user connects a laptop computer to the DRU management port, opens a session and updates the required parameters through the GUI.
