Configuring Radio Settings

The configuring Wireless Setting page allows a user to control the operation of the radio system.
A user can set up radio on/off, RF channel, beacon cycle, transmission power, IEEE 802.11 mode, etc.

SMT-R2000 can be set up as a dual-band AP.
Performance such as service range and tranfer rate is different according to each wireless mode.
Even though for the same wireless mode, the performance of SMT-R2000 may be different according to its environment.

AP operates in the following modes:

IEEE 802.11b mode
IEEE 802.11g mode
IEEE 802.11a mode

Item	Description
Radio	SMT-R2000 is a Dual Band AP. A user can designate Radio 1 or Radio 2. Set up both Radio 1 and 2 to use SMT-R2000 as a Dual Band AP.
Status (On/Off)	Click the On or Off button to determine the on/off status of the wireless settings (Radio 1/Radio 2).
Mode	A mode defines a standard of Physical Layer (PHY) used for wireless settings. SMT-R2000 can be operated as a single-band AP or dual-band AP. Single-Band AP: For Single-Band AP, select one from the following three modes. For other wireless modes, turn them off using the Mode menu. IEEE 802.11a IEEE 802.11b IEEE 802.11g Notes: For SMT-R2000, the IEEE802.11a mode can be set up only in Radio 1, and the IEEE802.11b or IEEE80211g mode can be set up only in Radio 2. Dual-Band AP: For Dual-Band AP, use the following combination: IEEE 802.11a / IEEE 802.11b IEEE 802.11a / IEEE 802.11g IEEE 802.11a / IEEE 802.11b / IEEE 802.11g Notes: For two-radio AP, each radio can be set up as a different mode by selecting a radio from the Radio item.
External Antenna	If a user is located out of the wireless range of SMT-R2000, it is available to expand the wireless LAN range using an external antenna. Using a separately purchased antenna line and antenna, install the antenna nearby the user and turn this function on.
Channel	A channel means a part of a radio spectrum used by a radio for data transmission and reception. The range of a channel and basic channel are determined by the radio interface mode. In most modes, the default settings are "Auto". If the channel settings are Auto, the AP selects a channel where the usage rate is lowest based on information on signal strength and traffic load. Except "Auto", it is available to select one from Channel 1 to 11.
Beacon Interval	An AP transfers beacon frames in regular intervals to notify the existence of wireless network. An AP basically transfers a beacon frame every 100m/sec (or 10 times per second). The unit of beacon interval is 'ms', and a value can be entered between 20 and 2000.
DTIM Period	Delivery Traffic Information Map (DTIM) is a message used for beacon frames. DTIM contains a signal to make a client containing data to transfer to AP stop the sleep mode. The DTIM period indicates how often to transfer DTIM messages after loading to beacon messages. Designate a value between 1 and 255. If the DTIM period is set up as "1", the DTIM message is included to all beacon frames. If the DTIM period is set up as "10", the DTIM message is included to every tenth beacon frame.
Maximum Stations	Designate the maximum number of clients to allow accessing to AP. (0 ~ 2007)
Transmit Power	Enter the transfer power of AP in the unit of %. The default value is 100%. Recommendations: If possible, set up as the default value (100%) to maximize the service range of the AP and reduce the number of AP for a network. To increase the capacity of the network, set up the transfer power of an AP low and arrange APs close. It reduces superposition and interference among APs. In addition, it makes a network safer when the transfer power of an AP is low, as a weak wireless signal is not transferred far.
Rate Sets	Set up the basic rate that the Supported rate Set of an AP and an AP broadcast to a network AP. The unit of Rates is Mbps. The Supported Rate Sets indicates the transfer rate supported by an AP. It is available to set up multiple transfer rates. An AP selects the optimum transfer rate considering error rate and distance with a client. The Basic Rate Sets is transferred to a network to communicate with other APs and clients in the network.
Enable Broadcast/Multicast Rate Limiting	It is available to improve the performance of all networks by limiting the number of packets transferred through a network. Some protocols multicasts or broadcasts packets that most network nodes do not consider for such as ARP request, and DHCP or BOOTP messages. For these protocols, if setting rate limit control, it is available to limit the number of redundant packs. Click the Enabled button to activate the Multicast and Broadcast Rate Limiting option. Click the Disabled button to activate the Multicast and Broadcast Rate Limiting option. The default settings of Multicast/Broadcast Rate Limiting are 'disable'. Until the Multicast/Broadcast Rate Limiting option is activated, the following items are in deactivation status.
Broadcast/Multicast Rate Limit	Enter the value of rate limit for broadcast/multicast traffic. The value of rate limit should be between 1 and 50 (the number of packets per second). The default values of rate limit and the value of the maximum rate limit are "50".
Broadcast/Multicast Rate Limit Burst	The value of Rate Limit Burst is a value of the number that network traffic allows traffic bursts before exceeding the rate limit. The default values of rate limit and the value of the maximum rate limit are "75".
