4) No interference to primary users or
unnecessary interference to other users.
5) Use the minimum power needed to
make and hold contact.
Note: IC documents RSS-Gen and RSS-210
refer to operation in this band segment and
I’m paraphrasing the regulations.
1) For licence-exempt, low-power wireless
devices, the peak power to the antenna
shall not exceed 1 watt with no more than
4 watts effective isotropic radiated power
(EIRP), unless used as a fxed point-to-point
link where EIRP can exceed 4 watts through
the use of gain antennas but not increased
peak power (RSS-210, A8.4 refers).
2) To use commercially manufactured
external RF amplifers with licence-exempt,
low-power devices, both of the following
conditions must be met (RSS-Gen, 7.1.1
refers):

a) It must be certifed for use with the
device, and the amplifer-device
combination can’t exceed any of the limits
specifed for the device alone. Figure 5A: Mesh Node Main Screen.
b) It must have the following statement on
the packaging and in the user manual:
“Under Industry Canada regulations, this
radio frequency power amplifer (insert
Industry Canada certifcation number of
radio frequency power amplifer) may only
be used with the transmitter with which
the amplifer has been certifed by
Industry Canada. The certifcation number
for the transmitter with which this
amplifer is permitted to operate is
IC:XX…X-YY…Y.”
Note: Operating under Canadian Amateur
Radio Service rules, the power limits don’t
apply because Amateurs can use higher
peak input power with unlimited EIRP unless
otherwise stated (as for the 60m and 30m
bands), up to the maximums allowed by
their Amateur Radio certifcate class.
However, Industry Canada pointed out
Radiocommunication Act, section 9(1) (b):
“No person shall (b) without lawful excuse,
interfere with or obstruct any
radiocommunication.”
Even if we can run higher power (peak input
or EIRP) we must be very careful not to
interfere with others, regardless if they are
licensed primary or licence-exempt users.

The Broadband Hamnet website has the THE HARDWARE port connected to the router with Ethernet
latest BBHN information and frmware, and 1) At least two fashed routers do a cable.
there are some excellent YouTube videos THE FIRMWARE
available. In hindsight, start with the Mesh network make. I bought mine on
eBay (WRT54GL’s and 54G’s), but many
videos frst because they will save you a such routers are collecting dust in ham 1) Download the specifc router model
lot of wasted “meshing” around time! shacks or elsewhere. frmware from the BBHN website.
2) Have a good read of the fash instructions
– it’s not easy to undo a “Whoops!”
