2.2.3 Using LGCell to Simultaneously Support Multiple
Bands/Protocols
The LGCell can simultaneously support more than one frequency band. Two options
include:
• The Dual Band LGCell for an Operator running parallel networks in the same mar-
ket
• The neutral host configuration, which is described here
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, including paging and messaging, 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 ser-
vice 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.
• 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 agree on how to share the equipment
and installation costs.
Additional distribution cabling infrastructure, beyond initial requirements, often is
installed to accommodate adding Operators or services or to enhance capacity by sec-
torizing the distribution equipment at a later time.
