1.2 The ES2440
The ES2440 High-Capacity Infrastructure Mesh Point is a
full-featured Fortress network device, providing strong data
encryption and Multi-factor Authentication™, including native
RADIUS authentication, to users and devices on the network it
secures.
The ES2440 contains four radios:
 Radio 1 is a 250 mW (milliwatt) dual-band 802.11a/b/g/n
radio that can be configured to use either the 802.11b/g
band or the 802.11a band, with an option for 802.11n
capability in either band.
 Standard equipment Radio 2, Radio 3 and Radio 4 are
500mW radios fixed on the 802.11a band, also with an
option for 802.11n capability. The ES2440 can be optionally
equipped with three 800mW 802.11a/n 4.4 GHz military
band radios in place of the standard equipment
Radios 2, 3,
and
4.
Any of the ES2440’s radios can function as a wireless access
point (AP), providing secure WLAN connectivity to wireless
devices within range and as a wireless bridge or node in a
mesh network.
The ES2440 is additionally equipped with an internal global
positioning system (GPS) receiver.
1.2.1 Hardware Models
CAUTION: Use of
4.4 GHz radios is
strictly forbidden out-
side of U.S. Department
of Defense authority.
You can identify by the full model number of the ES2440
whether it is equipped with standard 5 GHz 802.11a radios
(as
Radios 2, 3 and 4) or with 4.4 GHz military band radios.
 ES2440-3555 - standard equipment
 ES2440-3444 - military option
The 4.400 GHz–4.750 GHz frequency range is regulated by
the United States Department of Defense, rather than the
Federal Communications Commission (FCC). FCC markings
are therefore not applied to the ES2440-3444 chassis and
there is no FCC ID associated with these products.
Each model is equipped with the appropriate antenna port
(
ANT2) for the type of radio installed as Radio 2.
The two ES2440 models are otherwise identical.
