What is NTP Client?
NTP client is designed for fetching the current timestamp from internet via Network Time protocol.
User can specify time zone, NTP server IP address.
What is VPN?
VPN is the abbreviation of Virtual Private Network. It is designed for creating point-to point private
link via shared or public network.
What is IPSEC?
IPSEC is the abbreviation of IP Security. It is used to transferring data securely under VPN.
What is WLAN Block Relay Between Clients?
An Infrastructure Basic Service Set is a BSS with a component called an Access Point (AP). The
access point provides a local relay function for the BSS. All stations in the BSS communicate with
the access point and no longer communicate directly. All frames are relayed between stations by
the access point. This local relay function effectively doubles the range of the IBSS.
What is WMM?
WMM is based on a subset of the IEEE 802.11e WLAN QoS draft standard. WMM adds prioritized
capabilities to Wi-Fi networks and optimizes their performance when multiple concurring applica-
tions, each with different latency and throughput requirements, compete for network resources. By
using WMM, end-user satisfaction is maintained in a wider variety of environments and traffic con-
ditions. WMM makes it possible for home network users and enterprise network managers to
decide which data streams are most important and assign them a higher traffic priority.
What is WLAN ACK TIMEOUT?
ACK frame has to receive ACK timeout frame. If remote does not receive in specified period, it will
be retransmitted.
What is Modulation Coding Scheme (MCS)?
MCS is Wireless link data rate for 802.11n. The throughput/range performance of a AP will depend
on its implementation of coding schemes. MCS includes variables such as the number of spatial
streams, modulation, and the data rate on each stream. Radios establishing and maintaining a link
must automatically negotiate the optimum MCS based on channel conditions and then conti-
nuously adjust the selection of MCS as conditions change due to interference, motion, fading, and
other events.
