Motorola to Marry BPL and Wireless 79
prostoalex writes "Motorola is combining Intellon broadband-over-powerline chips with its own Canopy wireless systems to create an end-to-end broadband delivery system, where last mile delivery would be covered by wireless and broadband pipe would belong to electric utility. HomePlug AV standard will offer 200 Mbps downstream speed."

Oh, right.
There's a large, weather-proof step-down transformer that you could put a fiber-to-AC based router into.
Except when you don't because you're sending the signal out to reach two people out on the ranch. Fortunately, there's a whole hierarchy of the things, and you could put your switch at whatever level of the hierarchy is feasible for sustainable service.
Remember, we're talking about what to do about the last mile. If you've got so many people that they're starting to have collisions, you can afford to put in more routers. This really addresses the problem of what to do when you don't.

Canopy is a 'fixed wireless' sort of thing, so you would have an access point somewhere that could serve up to a few hundred or so subscriber modules. The subscriber modules would go on power poles, behind the transformers (ie, between the transformer and the end users). It would then be BPL from there into up to, if I recall, 8 homes or so. So, it lets you deploy Canopy to an area, but reduce your costs as you can feed more than one home with a single

I work at a company that does Canopy wireless broadband and it works great, IF you can see the tower.
The problem with putting a canopy unit on an electric pole and feeding it in through the power lines, is that you would have to put an access point every two blocks to have the needed line of sight to feed the SM, which in turn pumps it into the house (unless your town happens to be in

Implicit was my assumption that any system capable of servicing a profitable number of users at a data rate comparable to existing landline systems will require a carrier frequency that is line of sight anyway but that there are some benefits to that tradeoff that aren't readily apparant.

The $300 is high enough that people feel committed to the service (we don't need contract lock-in to keep customers) and is low enough that most of our customers can afford it. They can always take their SM to one of our competitors if they don't like our service.

Even with 900 Mhz, you still have line of sight issues unless you are very close to the access point. Putting the SM on a telephone post helps the problem, but it does not solve the problem because in many cases the trees are still higher than the pole. The only real-world solution is more access points, that would have to mounted very high, a

-the encryption suite is proprietary. while they do use AES as the encryption algorithm, the overall protocol is not based on IPSec, WPA, WEP, or any other standard
-subscriber modules use a manufacturers default encryption key to authenticate to the access point. a key management server must be implemented use a different key.
I don't know if any of that has been fixed in the past year or not. I have no clue how they got this device FIPS 140-2 certified. Unsurprisingly the security through obscurity worshipping government agencies I deal with are completely ga-ga over the Canopy.

You can still upgrade the units without CNUT, the CNUT
CNUT is just a Java front-end to a bunch of perl scripts that script the original update process. They even packaged up their perl bits in a tidy little module. You should be able to make CNUT run wherever Java and perl run.
I would not run any Canopy Firmware older than 6.1, and you should have a really good reason to not be running 7.0.7 or 7.2.9.
You should not have the management interface on a routed subnet. If you are that paranoid, turn on VLAN support and change the management VLAN. The management interface and daemons have a number of little quirks. None of them have caused any problems for us since we a) use private IP space for management and b) keep the management interface on a management VLAN.
The AES unit uses a more powerful FPGA which costs a bit more. Granted that is probably not enough to account for the price difference.
You can control some (SNMP) administrative access by subnet. It is
They provide a access control server that is a bit crude, but it has good API docs and does what we want it to, which is control access and limit bandwidth.
I'd like to see a RADIUS client as much as the next guy, but BAM works fine and has a well documented database schema and SOAP interface.
If you are truly paranoid, get the AES unit and use the reset plug to disable the management interface and turn it into a dumb bridge.
It is trivial to access a Canopy network if the network was thrown up in 15 minutes.
It can also be virtually impossible to access if the designer has implemented a VLAN and subnet segregated network, is using BAM, turns off AP Eval, etc.
In the end, I agree that their RF side is good and the code side could use some work. In practice, their code quirks are avoided anyway by using good practices elsewhere.
The Canopy radios are neat little software radios (the only difference between them is the size of the onboard antenna and software load.) I can't wait for someone to figure out how to reprogram them for some other purpose (802.11 or TV tuner or something.)
