<br clear=all>

** 2x configured at 5.8 GHz
** 1x configured at 2.4 GHz 
**(It maybe worthwhile to search and evaluate some of the new cards on the market, but our current "bokkie" routers use the above one from Miro)
** Suppliers we have used:
***http://www.miro.co.za/detail.aspx?pid=208&p=2&sp=&spp=
***http://www.pcengines.ch/wlm54sag23.htm 
**'''OR''' The R52H which is the same as the wlm54sag23, also manufactured by Compex. http://www.scoopdistribution.co.za/product_info.php?cPath=49_52&products_id=577 (still need to review though)

* 1x 1GB compact flash card (have used Kingston & Sandisk - but anyone that is compatible)

** 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 ===

== Software ==
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

=== 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

=== Security ===
* 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 ===
[[Image:Indicator_v2.png|right|thumb|150px|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)
