High Performance Node - Specification

Hardware

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

Block Diagram of HPN

Enclosure

Based on Poynting Enclosure (Product code:WLAN-A0033)
Modification: swap 1x 2.4 GHz omni-directional antenna for 1x 5.8 GHz omni-directional antenna

Electronics

1x Gateworks Avila Board
3x 802.11a/b/g mini PCI Atheros based WiFi cards
- 2x configured at 5.8 GHz
- 1x configured at 2.4 GHz
1x 1GB compact flash card
3x U.FL to SMA connectors

Enclosure - Other

1x External weatherproof Ethernet connector with Ethernet pigtail for POE (install on left side – looking at bokkie – keeping with current standard)
4x Gateworks board mounting standoffs
External Mounting bracket

Accessories

Powered 48V power-over-Ethernet injector
Ethernet Cables
- 1x UV resistant outdoor CATV cable [have different lengths available (5m, 10m, 20m)]
- 1x indoor CATV cable [have different lengths available (5m, 10m, 20m)]
- Need for longer cables, custom make ?
Some type of surge protection on the power side.
- Thinking of a product from http://www.clearline.co.za/. Still need to investigate

Other

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)

Software

Firmware: "bokkie1 mesh distribution"

This software specification is based on the current free BSD version of the firmware. I have named it "bokkie1 mesh distribution" as a working title (for want of a better name - please provide a nice snazzy one)

A script is used to build the current firmware build based on the platform. Please insert the list of packages\utilites\etc used to make this build.

Additional
- IPv4 over IPv6
  - Allows for automatic configuration of the tunnels
  - Automatic DHCP of IPv4
- Other?

GUI

Current details and functionality of the GUI

What configurations are done on the command line

Need details for further development on the GUI

Remote upgradeable

What current functionality exists?

What further development is needed?

What limitations exits?

Cannot be remotely upgraded if there is a protocol change

Further development to functionality

GSM modem to the development network and first nodes in the field
Watchdog
- 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
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.
Indicator for alignment
