wideband interconnect link option, distances of 20km can be reached. Moreover, these
environments require gradual investments, because initially operators tend to provide
radio coverage only in the busiest areas, and then extend it in order to reach complete
coverage later. The modularity of the ION-B helps operators to gradually expand the
system. Often, large cities set up seamless and reliable radio systems for emergency
services. In these cases, the required RF infrastructure needs to be unobstrusive and
environmental friendly; this can be achieved using an ION-B DAS. When redundancy
is required, two interleaved ION-B systems can be used, management and supervision
for these systems can be remotely established by means of an external modem and an
open protocol such as SNMP.
