The Altitude AP has two radios:
● a 5 GHz radio that supports the 802.11a standard
The 802.11a standard is an extension to 802.11 that applies to wireless LANs and provides up to 54
Mbps in the 5-GHz band. 802.11a uses an orthogonal frequency division multiplexing encoding
scheme rather than FHSS or DSSS.
NOTE
The Altitude 350-2 access point will automatically discontinue transmission in case of either absence of
information to transmit (no frames transmitted through Ethernet) or operational failure.
● a 2.4 GHz radio that supports both the 802.11g and 802.11b standards
The 802.11g standard applies to wireless LANs and specifies a transmission rate of 54 Mbps. The
802.11b (High Rate) standard is an extension to 802.11 that specifies a transmission rate of 11 Mbps.
Because 802.11g uses the same communication frequency range as 802.11b (2.4 GHz), 802.11g devices
can co-exist with 802.11b devices on the same network
Either radio on the Altitude AP can be enabled or disabled in the user interface. Both radios can be
enabled and offer service simultaneously.
The Altitude AP supports the full range of 802.11a:
WARNING!
The Altitude 350-2 utilizing the internal or detachable antennas are intended only for indoor use. This specifically
applies when the 5.15 to 5.25 GHz band is enabled.
The U-NII bands (Unlicensed National Information Infrastructure) are three frequency bands of 100
MHz each in the 5 GHz band designated for short-range, high-speed wireless networking
communication.
Altitude APs are licensed to operate in North America, the European Union countries and European
Union free trade countries. The Altitude AP will operate on the radio band allowed for each European
Union country, after being configured on the Summit WM-Series Switch in the Altitude AP Configuration:
Properties screen.
The Altitude AP has two models:
● internal antenna (Altitude 350-2 Integrated Antenna), internal dual (multimode) diversity antennas
● external antenna (Altitude 350-2 Detachable Antenna) (dual external antennas), RP-SMA connectors
For North America, the U-NII Low Band (5.15 to 5.25 GHz band) is disabled for the Altitude 350-2
Detachable Antenna to comply with FCC regulations.
5.15 to 5.25 GHz U-NII Low Band
5.25 to 5.35 GHz U-NII Middle Band
5.725 to 5.825 GHz U-NII High Band
New 5.470 GHz to 5.725 GHz Band
(when approved by FCC)
