Quanta 70: Installation and Configuration



Quanta 70 web interface is an intuitive and responsive user interface adjusts the layout based on the size of your screen. Automatic mechanisms such as auto-channel and automatic transmit power control optimize the link for maximum performance in interference free band.


Network Settigs

By default wireless device has IP address with network mask. The workstation used to perform initial configuration must have an IP address from the same subnet.

Login and Password

By default no login or password are set, use any letters or numbers for initial authentication.

2. Web Interface

Navigation in the web interface is performed using the side menu, which includes the following sections:

  • Dashboard.
  • Settings.
  • Service.


This section displays the following wireless real time statistics:

  • Connection status, information about the distance and link operation time.
  • Link parameters: center frequency, channel width, frame length, and the uplink/downlink ratio.
  • Link load and the retries number.
  • The current modulation and coding scheme, RSSI and EVM values on the local and remote devices.



The section is designed to configure the basic system parameters of the device.

  • Unit:
    • Device name - is an arbitrary set of characters. Is used for easy device identification by the network administrator, is displayed in the web interface in the "Dashboard" section.
    • Link ID - allows to avoid connecting to wrong devices in case of several adjacent links. Must be the same at both sides of the link.
  • Regulatory domain - allows to set complex system limitation in accordance with the requirements of local legislation, it makes configuration process easyer. Restrictions are applied to the following parameters:
    • Available frequency range.
    • Use of LBT (Listen Before Talk) technology.
    • Maximum EIRP value.
    • Radar detection performing.
  • SNTP:
    • SNTP Server Address - the SNTP server IP address, the SNTP service will synchronize the time on the device with. The device must have network access to the SNTP server.
    • Time Zone - the time zone at the place of device installation. For example: GMT + 5.


This section allows to configure device access and security settings.

  • Administrator access - here you may change system administrator account login and password, to change the identification data, click the "Change admin password" button. We strongly recommend you to set a login and password after the first login to the device.
  • Radius AAA - here you may configure a device access control using a remote RADIUS server.
    • Address - set the RADIUS server IP address.
    • Port - set the RADIUS server port.
    • Secret - set the server password.
  • Command line interface:
    • Allows to enable / disable remote device control by the command line using Telnet and SSH protocols.
    • SSH (Secure Shell) protocol provides secure remote control to network devices. Its functionality is similar to the Telnet protocol, but, unlike Telnet, SSH encodes all protocol messages, including transmitted passwords. By default, only access via Telnet is enabled.
  • Network access - this section is used to create a list of subnets from which access to the device will be allowed.
  • Radio authentication settings - units at both ends of the wireless link should authorize each other before link establishment. Access key must be up to 64 characters long, without spaces and must be the same at both ends of the link.


The section includes the radio subsystem parameters necessary for wireless link establishing.

  • Radio frontend:
    • Unit role - one of the devices must be "Master", the second - "Slave". Please note that the center frequency must be equal for "master" and "slave" unit to establish the radio link. When a wireless link has been established Slave unit will continuously inherit radio frontend parameters from Master unit excluding frequency channel grid. So, if you change some values on Master they will be set on Slave automatically.
    • Center frequency - should be selected manually in accordance with the actual frequency grid. The Quanta 70 accepts values i range 70500-76000.
    • Power limit - two ways of power limiting are available:
      • Transmitter power output - limits transmitter power to a specified value.
      • EIRP - limits the overall system transmitted power, calculated by the formula: transmitter power + antenna gain (should be set in the field below).
  • Air frame:
    • Frame length:
      • The greater frame length the more payload will be transmitted in one frame. Greater values increase latency.
      • The lower frame length the less payload will be transmitted in one frame. Lower values decrease latency.
      • Available values: 0.1; 0.2; 0.5 ;1; 2; 5 ms.
    • Downlink/Uplink ratio - available only on Master unit. In automatic mode, the ratio changes dynamically in accordance with the transmitted traffic. Manual mode allows to set a fixed value using the slider. Available values depend from frame length.
  • Automatic modulation and transmit power control:
    • AMC strategy - allows to select a strategy of modulation switching for cases when the transmission medium conditions change. The following strategies are available:
      • Normal - keeps balance between the number of errors and bandwidth.
      • Conservative - assumes using higher CINR thresholds in order to minimize the error rate.
      • Aggressive - lowers the thresholds in order to use higher modulation levels and thus increase the throughput.
    • Automatic transmit power control - controls transmitter output power automatically based on target RSSI value. If actual RSSI level is lower then unit increases transmitter output power of the remote unit and vice versa. ATPC could not set value that may exceed the "Power limit" value.
    • Target RSSI - RSSI value which will be used by ATPC as target.
  • Frequency channel grid - the frequency grid allows to limit the frequency range available to use. Values can be set as a range (70500-72500) or as a list (71500, 73400, 75600) with the step from 0,125 MHz till 10000 MHz.


This section allows to assign an IP address or several addresses to the wired interface, the default gateway value can also be specified.

Click the "Add IP address" button to add a new address. There are two ways to assign an IP address:

  • Automatically - the IP address will be obtained automatically from the DHCP server.
  • Manual - the IP address and netmask are specified manually.

The VLAN tag value can also be set in this section, the VLAN ID value should be in range from 1 to 4096.


  • Network ports - each Quanta 70 family device has 3 interface:
    • ge0 - combo port, depends on physical connection type can be Gigabit Ethernet 1000BASE-T or SFP Port 1000BASE-X (to specify the connection type see "Wired interface" section on the Dashboard). Only ge0 interface is available to configure. The following parameters can be changed:
      • Status: enabled/disabled.
      • Duplex: duplex mode, "auto" is by default.
      • Description: arbitrary text description.
    • radio - internal radio interface;
    • mgmt - internal interface for device management.

  • QoS - enable/disable prioritization strategy. Unit will recognize the 802.1p tags in Ethernet frame headers. Based on these tags priorities will be autlomatically assigned to the frames when they are sent over the radio interface. After transmission over radio interface frames with tags are sent to Ethernet. Priorities may be adjusted manually if a VLAN based switching is enabled.

  • VLAN based switching - allows to create list of allowed VLANs and their handling on the unit switch plane. If VLAN based switching is enabled but no VLANs are added, device ports will allow untagged traffic only. Each entry of list establishes the relationship between VLAN ID and ports VLAN modes.
    • VLAN ID -VLAN tag in range from 1 to 4095. May be set in a few ways, examples:

      • 12
      • 10-20
      • 100,200,300
      • 23,24,25,50-100
    • Description - arbitrary text description.

    • Priority - allows to set the priority of a specific VLAN according to 802.1p ranging from 0 to 7, where 0 - the lowest priority level, 7 - the highest.

  • Connectivity matrix - allows to configure the traffic transfer between the network ports of the device. Configuration is performed visually using switches. The green switch indicates allowed connections, the red one - denied:
    • ge0 - wired port.
    • radio - internal radio interface;
    • mgmt - internal interface for device management.

Traffic flow between ports is performed in accordance with VLAN modes set, if the VLAN based switching is enabled.
