Thank you for your confidence in us!
LANCOM L-305agn Wireless, LANCOM L-310agn Wireless and LANCOM
L-315agn dual Wireless are professional access points that provide a maxi-
mum wireless LAN performance of up to 300 Mbps thanks to the support of
the IEEE 802.11n draft 2.0 standard. The access points operate either in the
2.4 GHz or in the 5 GHz frequency band. LANCOM L-315agn dual Wireless
works with two integrated radio modules (one IEEE 802.11abgn, one IEEE
802.11abg), both of which can operate simultaneously in the 2.4- and/or
5 GHz frequency range. The 5 GHz band is not used as much and, offering a
larger number of channels, it provides better opportunities to establish
non-overlapping wireless cells. The L-300 Access Point series models can ope-
rate in stand-alone mode, in managed mode or in client mode. The access
point can be used in managed mode with a LANCOM WLAN Controller wit-
hout any additional software upgrades.
The 802.11n Draft 2.0 standard includes many new mechanisms—such as
the use of MIMO, 40-MHz channels, packet aggregation and block acknow-
ledgement—in order to increase the bandwidth available for user applicati-
ons significantly. This allows a more than fivefold increase in speed over
802.11a/g networks with physical data rates of up to 300 Mbps.
MIMO (multiple input multiple output) technology allows the L-300 Access
Point to transfer several data streams in parallel and thus significantly improve
data throughput. MIMO uses several transmit/receive units for both the trans-
mitter and the receiver. The separate data streams are identified by unique
characteristics that result from the different paths that the data take. By pro-
cessing multiple data streams MIMO achieves not just higher data throughput
but also better coverage (fewer "radio black spots") and better stability. These
are the most important arguments for 802.11n for commercial customers in
particular.
