High Performance Node Development & Test Network

moved to High Performance Node - Dev and Test Network


Current Bokkie router (Poynting)

HPN based on current “Bokkie” router, to become “Bokkie v2”

Block Diagram of HPN

Block diagram of HPN


  • Based on Poynting Enclosure (Product code:WLAN-A0033)
  • Modifications to the WLAN-A0033 are needed: swap 1x 2.4 GHz omni-directional antenna for 1x 5.8 GHz omni-directional antenna


Gateworks Avila Network Platform

High Power dual-band Mini PCI Card

  • 1x 1GB compact flash card (have used Kingston & Sandisk - but anyone that is compatible)
Current Compact flash card being used

U.FL to SMA pigtail (300mm)

Enclosure - Other

  • 1x External weatherproof Ethernet connector (UTP Gland) with Ethernet pigtail for POE (install on left side – looking at bokkie – keeping with current standard)

Weatherproof UTP gland
  • In the first assembled version we received, this External weatherproof Ethernet connector has been changed to a Poynting designed one. See pics below.

  • 4x Gateworks board mounting standoffs (supplied as part of the enclosure)
  • External Mounting bracket (supplied as part of the enclosure)



  • Wall mounting bracket (different types depending on type of wall - specification)
  • Mounting pole (different types - spec)
  • M10\M12 Coach Screws and fisher plugs (# depending on wall mounting bracket)
  • 10x pack Cable ties
  • Earthing kit Webb Industries have earthing kits that can be used. see http://www.webb.co.za/index.php?nav=news&ID=50
    • Clamp\lug on one end of earthing cable for attachment onto wireless installation mounting bracket
    • Earthing cable: Length (?), Gauge (?) - 10-15mm diameter
    • Clamp on spike for other end of earthing cable for attachment onto earthing spike
    • Earthing spike - 1m (driven into the ground at base of wall of the wireless installation)


Moved to High Performance Node - Software

Further Developments to Functionality

Remote upgradeable

  • What current functionality exists?
  • What further development is needed?
  • What limitations exits?
    • Cannot be remotely upgraded if there is a protocol change

Back channel into HPN for monitoring\testing

  • GSM modem to the development network and first nodes in the field


  • Problem with native watchdog on Gateworks Avila board
    • Boot failure resuscitation
    • Specific to Gateworks Avila Board
  • PCB to be developed that plugs into the JTag connector


  • WEP security

GPS co-ords

  • Mechanism to get the GPS co-ord configured in the HPN. This can later be used in the visualisation tool on the gateway with a Google plot of the nodes.

Alignment indicators

LED type indicator system
  • Visual: Example of indicator system (using LEDs mounted at the bottom of the enclosure) for alignment, type of box (ie. red or green, which is an indication of the channel being used), power to box
    • 1 - Left most LED can be either RED or GREEN, showing type of box - this can be configured in the setup and commissioning of the router(indication of the channel being used), ie. this is either a red box or a green box
    • 1 - Right most LED shows power
    • 2 - 5 Used as 4 point scale for signal strength
  • Audible: with a buzzer used for alignment
    • Check the power consumption (especially for multiple LEDs), and how to start/stop the beeping mode (may also be used for LEDs)
