Applications
Designed for rugged environments and installations that require antenna versatility, the Cisco
Aironet 1240G Series features antenna connectors for extended range or coverage versatility
and more flexible installation options. Manufacturing applications, for example, can place WLANs
in hazardous locations and remotely place antennas in those locations while securing the Cisco
Aironet 1240G Series Access Points.
The metal housing and industrial-grade components of the Cisco Aironet 1240G Series provide
the ruggedness and extended operating temperature range required in factories, warehouses,
“big box” retail environments, and similar facilities. High transmit power, receive sensitivity, and
delay spread for 2.4-GHz radios provide the long range and large coverage area consistent with
these applications. Access points can be placed above ceilings or suspended ceilings, allowing
antennas to be discreetly placed below drop ceilings. The UL 2043 rating of the Cisco Aironet
1240G Series allows for placement of the access points above ceilings in plenum areas regulated
by municipal fire codes. Public access applications such as large hotel buildings can also present
a challenging RF environment; the antenna versatility of the Cisco Aironet 1240G Series, together
with industry-leading range and coverage, provides reliable performance for the most demanding
environments.
