2.1 System Overview
The LGCell acts as an extension of the outdoor, macrocellular network to provide 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 cov-
erage 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
