The BCIT ARC is back on BCWARN with a new 5.8ghz data link. This new radio replaces the previous VINE radio which operated at 2.4ghz.

BCWARN is a network of EOC (Emergency Operations Centers) and radio clubs which support emergency communications. The BCWARN network is based on high-elevation sites which act as hub-nodes for the network. These nodes are often multi-homed with other sites, forming a partial-mesh or ring topology. The current network map shows a ring between UBC (main internet gateway and server host), SFU (busiest RF site), and Mount Seymour (Highest elevation location), as well as a ring between SFU, UBC, and a high rise in Burnaby known as “The Boot”. These multiple rings allow for sites to fail without sever impact to other sites in the network.

BCIT is a single homed site as SFU is the only site which BCIT can see reliably. A path to Mount Seymour is not possible due to tree cover, even though the mountain is prominent to the north.

Check out the installation photos, and a time-lapse below:

A special thanks goes out to Jeremy (VA7NSA) and Ian (VE7HHS) who did the tower work. Ground support was provided by Duncan (VE7NEO) and Patrick (VE7SDI) while I “supervised” the stationary camera.

Cheers, VE7WNK

Lack of updates…

Hey followers,

You may have noticed a lack of updates of the last while. This is because I have been in the middle of a research project that has kept me busy. I am a BCIT student and my graduation project has me tinkering with in-car electronics systems looking for vulnerabilities. This research has lead me into looking into some really interesting RF-related systems which are used to attack the car’s internal wireless systems. Once I have more info I will make it available.

I am going to be slow with updates, so please don’t mistake this for any abandonment of this website. Thanks for following!
