What LGCell Is
LGC
ell
is a “plug-and-play” in-
building distributed antenna
system (DAS) that enables
highly reliable, high-quality
wireless communications.
This one-person-one-phone
capability gives a wireless phone
user the ability to use their
wireless phone in any location
throughout the enterprise and
beyond.
Seamless coverage lets wireless
phone users roam freely between
buildings as well as indoors and
outdoors without changing
phones.
An LG
Cell
system has the
following equipment:
• Main Hub (MH)
• Expansion Hub (EH)
• Remote Antenna Unit
(RAU)
Double-Star Topology for Easy, Cost-Effective Growth
The LG
Cell
system uses a double-star topology, which allows for easy, cost-
effective growth of coverage and/or capacity. Each Main Hub supports up to four
Expansion Hubs. Each Expansion Hub, in turn, supports up to four RAUs.
The Main Hub is located in an equipment closet and the Expansion Hubs are
distributed out into other equipment closets throughout a building. The RAUs are
then distributed off each Expansion Hub to provide coverage.
Bringing Outside In – Increases Wireless Network Coverage
Outdoor macrocellular base stations (BTSs) transmit and receive Radio Frequency
(RF) signals, which enable communications with wireless phones. The RF signals
are not always available or adequate inside a building, campus, tunnel, subway, or
other hard-to-reach location. The LGC
ell
system delivers high-quality wireless
