—RTS Threshold –maximal requested size of data for transmission. In CSMA/CA technology RTS
packets (request to send) are sent to the base station before transmission of real data. If a free
window is available, the base responds with CTS packet (clear to send) and the client sends he
packet of requested size. The less RTS size is, the more is the probability to receive permission
from base station, the quicker is the network recovery after collisions, but the less is the
performance of the network as a whole. Takes values from 0 tо 2347;
—Beacon Interval –time interval between service messages (beaconing) in wireless network. Service
messages transmit parameters of frequencies, protocols, safety, transmitted powers, delays etc.
Takes values from 20 to 1024;
—IAPP –IAPP protocol (Inter-Access Point Protocol) allows to use roaming of clients between
multiple access points within one network segment;

—Protection –is a special mechanism for 802.11 b/g networks. Activation of the mechanism secures
the performance of slow devices of b standard in the media with multiple high-speed devices of g
standard. It is reached by increase of service time of old clients, assigning lower RTS window for
them, decreasing general network performance;
—Aggregation –includes possibility of unifying some little packets for transmission in one big packet;
—Short GI –mean of decrease errors by interaction of radio devices —empty interval between
transmitted sixteen-digit symbols (0,1,...E,F). Standard long guard interval (Long GI) lasts 800ns. It
is considered that a signal approaches the receiver during the time considering all delays and
reflections. Upon expiration of this interval, the next symbol is transmitted. Short GI lasts 400ns.
Use of short GI increases general wireless network performance by approximately 11%, but leads
sometimes to increase of transmission/receiving errors;
—WLAN Partition –activation of restriction to interact for wireless clients with each other;
—STBC –activation of Space Time Block Coding (STBC) mechanism, is used in wireless networks for
transmission of data flow copies via multiple aerials and for securing receipt of different versions of
data block for increase of data exchange durability. It is known that radio signal is spread in the
media according to complex traces and exposed to reflection, refraction, dissemination, as well as
aberration through heat noise of the receiver, which finally leads to the situation when one copies
of transmitted signal may occur as sufficiently better (less distorted) than the others. This
redundancy increases probability to decode the signal correctly from some of its copies at
receiving side. STBC technology unites all copies of received data block optimally for retrieval
maximal information from each of them;
—LDPC –use of correcting code with Low-density parity-check code (LDPC), which allows to detect
and correct possible errors at signal transmission via wireless interface more effective;
—TX Beamforming –a technology, providing formation of electromagnetic fields of basic station
aerial in far-filed region as narrow-band remote lobe, directed to subscriber device with possibility
of change of directed features by change in position of this equipment;
—Multicast to Unicast –allows to transmit a Unicast stream to wireless Multicast devices, provided
that UDP2HTTP option in WAN interface settings is switched on;
—RF Output Power –adjustment of access point signal strength in per cents from maximal level.
