A Complete Solution for Wireless
ISPs, Local Utilities, Municipalities,
Hospitality and Enterprises
The WR4500 family of dual band outdoor
wireless base routers and routing CPEs allow
the building of wireless only or hybrid IP
networks that are scalable, reliable and fully
controllable.
Wireless ISPs can easily and quickly provide
homes in rural areas with broadband Internet
access and VoIP telephony and, at the same time,
can set-up WiFi hot spots for nomadic users.
Enterprises can connect remote buildings
without the need for expensive leased lines and
can extend WiFi coverage to outdoor yards
providing users with mobile intranet and
Internet access everywhere.
Municipalities can build wireless IP networks for
connecting remote offices and for increasing
public safety with real time monitored
surveillance cameras and continuous
communication with local police patrols.
Local utilities can easily control their remote
equipments and read, in real time, gas, water
and electricity meters without any need for
expensive fiber cabling.
Hot spot services can be provided to hotel
guests and hospital patients ‘illuminating’ rooms
from outside the building with a reduced
impact on medical equipments because no
transmit radio will be installed inside the
hospital.
Allied Telesis
Both models can be used either as CPEs in
Point to Multipoint links or as both ends of a
Point to Point link.
Key Features
Flexibility is the primary advantage of
AT-WR4541wireless routing CPEs. Both models
share the same firmware, radio module and
enclosure.The only difference is in the
embedded panel antenna: AT-WR4541a
features a 15dBi 5GHz antenna while
AT-WR4541g is equipped wth an 11 dBi
2.4GHz antenna.
• Real IP routing functionalities
• Feature rich firmware
• 2.4 GHz and 5 GHz dual band operations
• IEEE 802.11a/b/g/h compliant
• Certified for HiperLAN bands operation in
Europe with DFS and TPC
• Power over Ethernet remote powering
Both models feature an additional type N coax
connector for using any 2.4 or 5GHz external
antennas.
Real Wireless IP Routers
WR4500 dual band wireless routers have all
the features of IP routers and much more. A full
set of routing protocols together with
enhanced filtering capabilities make the
WR4500 series the best choice for building
simple and complex wireless and hybrid (wiredwireless) networks with a tight integration
between the wired and wireless parts.
IP routing allows network designers to design
and deploy fully redundant networks with
predictable behaviour in any working condition,
while network operations managers retain full
control over packet forwarding.
Point to Point, Point to Multipoint as well as
partially or fully meshed networks can be easily
designed and deployed with limited need for
deciding in advance the network architecture.
Common network management tools can be
used for configuring and monitoring the
network and its users the usual way. Any
network engineer will be able, with little
wireless training, to design and troubleshoot an
Allied Telesis powered wireless network.
