Node A RF Enhancer
Node A RF Enhancer
Andrew Solutions digital Node A RF Enhancer supports up to four separate frequency bands,
and up to 24 interleaved sub-bands or up to 32 narrow band channels, in one
unitwhether 2G, 2.5G, 3G, or 4G cellular, iDEN, TETRA, the recently auctioned
700 MHz or other frequency bands. Wireless operators can use the Node A to
bring all of their outdoor frequency bands into small- and mid-size buildings,
providing coverage for customers where they increasingly want to use handheld
devices. The Node A is a cost-effective alternative to installing base stations
and fiber-based distributed antenna systems (DAS), which typically are used
for coverage inside large venues such as stadiums and airports. The Node
A performs the same function but at lower costs. The Andrew Solutions Node A is a digital
multi-band repeater. With its multi sub-band frequency selection in combination
with a passive distribution system it enables high quality voice and high
speed data service in larger buildings where it was previously not available.
Besides the wireless operator market another important application of the
Node A is with building owners needing to support multiple forms of wireless
communications including mission-critical systems. In the wake of national
emergencies like Hurricane Katrina, US firefighters, police, and other first
responders increased their demands for reliable ubiquitous radio coverage to
ensure the publics safety, as well as their own. Many municipalities and counties
across the US are adopting in-building coverage ordinances in response to these demands,
requiring building owners and commercial developers to install wireless coverage
equipment inside their buildings. The Andrew Solutions Node A enables high rise developers,
for example, to supply the two bands needed by local emergency personnel and
market to tenants the remaining two bands for in-building cellular or broadband
signals, helping recoup the cost.
Node A Cabinet with 3 RF Cards (up to four are possible)
Another application for Node A is in the healthcare industry, which is experiencing a
boom in wireless deployments within hospitals and across medical campuses. Wireless
portable devices improve work flow, productivity, and process automation with
electronic patient records, remote patient monitoring, staff location tracking,
and other innovations. Voice over Internet Protocol (VoIP) smart phones reduce
voice costs and increase staff mobility. Healthcare facilities are some of the
most RF intensive environments with more and more devices going wireless. Andrew
