Can be centrally managed, configured, and upgraded through the Mobility
Controller to take advantage of network changes and security improvements
Ethernet Compatibility
The Aruba AP 70 attaches to 10/100 Mbps Ethernet (FE) LAN segments that
utilize 10Base-T/100Base-TX (twisted-pair) wiring. The device appears as an
Ethernet node and performs a routing function by moving packets between the
wired LAN and remote workstations on the wireless infrastructure.
Radio Characteristics
The Aruba AP 70 can be configured to support IEEE 802.11a or IEEE 802.11b/g
operation as an AP , and supports both IEEE 802.11a and IEEE 802.11b/g
operation as an AM:
802.11a provides a high data rate and reliable wireless connectivity
802.11a operation uses a radio modulation technique known as Orthogonal
Frequency Division Multiplexing (OFDM), and a shared collision domain
(CSMA/CA). It operates in the 5 Ghz Unlicensed National Information
Infrastructure (UNII) band. Data is transmitted over a half-duplex radio channel
operating at up to 54 Megabits per second (Mbps).
802.11b provides an alternative to wired LANs that can dramatically cut costs
802.11b operation uses the IEEE 802.11 High-Rate Direct Sequence (HRDS)
specification, and a shared collision domain (CSMA/CA). It operates in the 2.4
Ghz Industrial/Scientific/Medical (ISM) band. The ISM band is available
worldwide for unlicensed use. Data is transmitted at speeds of up to 11
Mbps.
802.11g provides a high data rate and is backwards compatible with 802.11b.
802.11g operation uses ODFM and a shared collision domain (CSMA/CA). It
operates in the 2.4 Ghz Industrial/Scientific/Medical (ISM) band. The ISM
band is available worldwide for unlicensed use. Data is transmitted at speeds
of up to 54 Mbps.
Power Over Ethernet
The Aruba AP 70 supports the IEEE 802.3af standard for Power Over Ethernet
(POE). With this feature, the Aruba AP 70 can accept electrical power from a
compatible POE-capable device (such as the Aruba 5000 (with Line Card
LC-5000-24FE-2GE-SPOE), Aruba 2400, or Aruba 800) directly over the FE cable.
POE eliminates the need to provide separate power outlets in environments that
are difficult or undesirable to wire for electricity.
