LGCell 4.0 System Description

2.1 System Overview

The LGCell acts as an extension of the outdoor, macrocellular network to prov ide RF
signal coverage and capacity to places where the signals are not always available or
adequate, such as inside a building, tunnel, subway, or other hard-to-reach locations.

LGCell features:

• Supports all cellular protocols.

• Provides uniform radio coverage.

• Distributes cellular signals through standard multimode fiber (MMF) and standard
UTP/STP cables, which are found in most office buildings.

• Uses a double-star topology, which allows for easy, cost-effective growth of cov­erage and capacity.

The LGCell system consists of three components, as shown (from top to bottom) in
the following figure:

• Remote Access Unit

• Expansion Hub

•Main Hub

2.2 System Operation

Downlink (Base Sta ti on/Repeater to Wireless Handsets)

• The LGCell syst em’s Main Hub is usually installed in a 19 in. (483 mm) equip­ment rack in a wiring closet or equipment room inside the facility where coverage
will be provided. Coaxial cable is used to connect the Main Hub to a local base sta­tion or to a repeater that is attached to a roof-top antenna. The Main Hub receives
the incoming RF signals and splits them to feed four internal fiber optic transceiv­ers that convert the RF signals to optical signals. The Main Hub transmits the opti­cal signals over multimode fiber to up to four Expansion Hub s , which are usually
installed in other telecom closets throughout the facility.

WARNING: Exceeding the maximum input power could cause failure
of the Main Hub (refer to Section 7.1 on page 7-3 for maximum power
ratings). Attenuators may be required to limit the max imum composite
power into the Main Hub.

System Operation

•The Expansion Hub converts the optical signals back to electrical signals, which
are then transmitted to up to four Remote Access Units (RAUs) over Cat-5
UTP/STP cabling.

•The Remote Access Unit receives the electrical signals from the Expansion Hub
and transports the signals over a short coaxial cable to an attached passi ve antenna,
which then transmits the RF signals to wireless handsets.

Uplink (Wireless Handsets to Base Station)

• The passive antenna relays the RF signals from wireless handsets to the Remote
Access Unit, which then transmits the signals to the Expansion Hub over Cat-5

UTP/STP cabling.

•The Expansion Hub converts the electrical signals to optical signals and transmits
the signals to the Main Hub over MMF.

•The Main Hub converts the optical signals to the proper frequency band RF sig-
nals and sends them to a local base station or to a repeater that is connected to a
roof-top antenna.

base station. In this configuration, the base station provides voice channel capacity
and the LGCell provides coverage.

With the LGCell/base station/PBX* solution, employees can use a wireless phone in
place of a wireline desk phone to access the PBX while inside the building and use
the same phone for wireless communications while outside the building. Employees
can access PBX features such as four-digit dialing, call delivery, call forwarding,
call-waiting, conferencing, and voice mail from their wireless phone.

In this configuration, the base station private wireless network transmits RF signa ls
indoors, and the macrocellular network takes over outdoors.

*Check with your PBX manufacturer/vendor for compatibility, connection, and oper­ation.

LGCell 4.0 System Description

2.2.3 Using LGCell to Simultaneously Support Multiple
Bands/Protocols

An LGCell neutral host configuration can simultaneously support more than one fre­quency band and/or protocol. The term “neutral host” refers to the fact: that the sys­tem supports multiple wireless Operators, and that the equipment typically is owned
by a third-party company.

Neutral host systems are deployed in situations such as the following:

• Public microcellular applications such as airport terminals, subways/train stations,

and similar public buildings usually require that the in-building RF distribution
system infrastructure be capable of supporting any current frequency band and
protocol, and that it be future-proof.

• It is common for the same service provider to be licensed to operate in multiple

bands in the same geographical area. For example, some Asian and European ser­vice providers have licenses in both 900 MHz and 1800 MHz bands. Some North
American service providers operate in both 800 MHz and 1900 MHz bands.

Some service providers overlay networks (i.e., 900 and 1800 MHz) to alleviate
capacity constraints.

• A building owner will often allow service providers to provide wireless service in

their building only if they cooperate and share the infrastructure equipment and
distribution system. Delays in service implementation and loss of revenue occur
when the competing service providers do not ag ree on how to share the eq uipmen t
and installation costs.

Additional distribution cabling infrastructure, beyond initial requirements, often is
installed to accommodate adding Operators or services or to en hance capacity by sec­torizing the distribution equipment at a later time.

System Operation

Neutral host systems are deployed as shared or dedicated systems.

• Shared System: Multiple wireless Operators use the same set of LGCell hard-

ware to distribute RF signals.

• Dedicated System: Each Operator uses an independent LGCell system.

In order to simplify coverage pl anning and mini mize installati on costs, the equ ipment
is “clustered” and installed in groups. The number of Hubs and RAUs required for a
system is determined by their ability to be shared.

The configuration shown in Figure 2-7 supports up to 7 Operator bands.
