Properties
Link Type
Link type is a mode of choosing a wireless connection between AP and SU radios. A Link type here can be a PTP/ PTMP
Radio Mode
Outdoor Base / Outdoor Subscriber
If the Radio Mode is Outdoor Base, it is considered as AP.
If the Radio Mode is Outdoor Subscriber, is selected then it is a SU.
Service Set Identifier (SSID)
SSID is simply the technical term for a network name. The SSID is a string with 32 characters, supports configuration of alpha-numeric and special characters. An SSID is publicly visible. Within those rules, the SSID can be anything for quick identification of the network.
Country: US 5 GHz
Band1: 5160 - 5240 MHz
Band2: 5735- 5840 MHz
Operational Mode: 11AC
Bandwidth: 20/40/80MHz
Given the above options, the admin has the flexibility to select the bandwidth. In general, 2.4GHz radio can have a bandwidth of 20 MHz i.e. for short distances. 5GHz radio can have 40 MHz/ 80MHz bandwidth. Advantages of a 5 GHz with 40 MHz/ 80MHz bandwidth are; it is tuned for faster speed; more data can be transferred and less signal interference.
Channel: A channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a wireless radio channel through which a message is sent to its intended receiver. Several Wi-Fi Channels and their numbers were pre-defined to achieve the best performance.
Traffic Shaping: By default, traffic shaping is disabled, the operator can create shaping policies if required to limit traffic and then enable the traffic shaping and configure the uplink/downlink limit values.
Uplink Limit: The administrator can set this limit only when traffic shaping in enabled, and the limit range is (64-867000) Kbps that is from SU to AP.
Downlink Limit: The administrator can set this limit only when traffic shaping in enabled, and the limit range is (64-867000) Kbps that is from AP to SU.
Wireless Inactivity Timer: This parameter is configured only in SU, if there is no activity on wireless interface of SU in a specified time interval, reset the wireless interface. The value should be configured in minutes. An event log is generated when wireless inactivity triggers.
Link Inactivity Timer: If there is no activity on Wireless link on SU in a specified time, reset the wireless interface. An event log is generated when link inactivity triggers. The value should be configured in minutes.
Max SUs: This parameter is configurable only in AP and allows value from 1-32.
Retries: This can be configured to allow a packet to be re-transmitted in specified attempts.
MIMO
To configure MIMO, Click Wireless> 5 GHz Radio Configuration > MIMO
OR100 Series devices support Multiple-Input-Multiple-Output (MIMO) antenna technology that uses multiple antennas at both the transmitting end and receiving end to improve communication performance.
The transmitting antenna uses multiple radio Tx chains and signal paths to simultaneously transmit different data streams, whereas the receiver combines the Rx signals resulting in higher throughput. By increasing the number of receiving and transmitting antennas, the throughput of the channel increases linearly resulting in high spectral efficiency.
DDRS
Dynamic Data Rate Selection (DDRS) feature adjusts the transmission data rate to an optimal value and provides the best possible throughput according to the current communication conditions and link quality.
To configure DDRS/ATPC, Click Wireless> 5 GHz Radio Configuration > DDRS/ATPC
Select the Spatial stream as either as Auto, Single, or Dual.
Dual Stream: Select Dual for higher throughput.
Single Stream: Select Single for reliability and longer range.
Auto Stream: When you select Auto, DDRS decides the stream modes based on the environmental conditions.
Note: The data rate can be varied from min to max based on SNR and Retransmission percentage.
ATPC
To configure DDRS/ATPC, Click Wireless> 5 GHz Radio Configuration > DDRS/ATPC
When you enable the Adaptive Transmit Power Control (ATPC), the device automatically adjusts the transmit power to avoid saturation of remote receiver which could cause data errors leading to lower throughput and link outage. When you disable the ATPC, manually adjust the transmit power. The range should be between (1-26) dbm.
Security
To configure Security, Click Wireless> 5 GHz Radio Configuration > Security
When you enable the Adaptive Transmit Power Control (ATPC), the device automatically adjusts the transmit power to avoid saturation of remote receiver which could cause data errors leading to lower throughput and link outage. When you disable the ATPC, manually adjust the transmit power. The range should be between (1-26) dbm.
Encryption Type: Select WPA2-PSK
Key: Select any desired key considering the note below.
Note: If the encryption type is selected as none, then there exists any security to the data frames transmitted over the wireless medium
MAC-ACL
MAC Access Control List is an additional security mechanism in a wireless network.
To configure MAC ACL in AP (5GHz), Click Wireless> 5 GHz Radio Configuration> MAC ACL
This section has MAC status: Allow / Deny / Disable and a MAC ACL table: MAC Address
Disable: By, default MAC ACL is disabled in AP (5GHz) Configuration, i.e. all SU’s are linked to AP
Allow: If Allow is selected, the MAC ACL feature allows only the authenticated SU’s to access the wireless network of AP by adding their MAC addresses
Deny: If Deny is selected, only a particular SU is restricted.
Note:The maximum number of SU’s that can be added to the MAC ACL table is 32 MAC ACL feature is applicable only in AP with 5 GHz / 2.4 GHz
DCS (Dynamic Channel Selection)
To enable DCS, Click Wireless> 5 GHz Radio Configuration> DCS
The DCS parameter allows an AP to monitor the retransmissions of packets transmitted to the associated SU on the current operating channel. When the average of Local RTx percentage of associated SU crosses user configured DCS threshold value, before switching to new channel, AP evaluates local RTx percentage for 30 sec and triggers Spectrum Analyzer to scan the medium.
The Spectrum Analyzer scans for less interference channel and associates with SU to the best channel available.
Note:The maximum number of SU’s that can be added to the MAC ACL table is 32
MAC ACL feature is applicable only in AP with 5 GHz / 2.4 GHz
The DCS threshold is user selectable range (0-100) % and is activated only when DCS is enabled.
Default chosen DCS threshold is 50%, when this percentage limit exceeds, the AP activates spectrum analyzer.
