EkoLink II
16
EkoLink II system would be a multi-floor building such as the one depicted in
Figure 1. In buildings of this type it is common to find equipment rooms for
Heating, Ventilation and Air-Conditioning (HVAC) and other utilities such as data
networking and telephony equipment.
There are numerous advantages to centrally located utilities and services and
cellular equipment is no exception. Since the fiberoptic antennas cover the entire
cellular band and are format independent, they are capable of sending any type of
signal throughout the building, whether analog, digital or CDPD, and they can send
them all simultaneously.
The fibers typically emanate from a source point (small base station) in the
building. These fibers run from that source point, piping the signal to many
locations throughout the building as shown in Figure 1.

Because the capacity is determined by the base station equipment, not the
antennas, once a building is wired for RF distribution via fiber optics, capacity and
new services can be added without any changes visible to the customer.
