Sure, and the speed of vehicles is measured in kph (and probably frequencies in 
cps, or in this space more likely kilomegacycles).

I didn’t complain about anything. 
 
I just noted the very low technical competence signaled by this usage in the 
press release (what pushed me over the edge was of course the “terra”).  
Competence signaling is often inadvertent, and it can be very useful for the 
recipient of a message.

To keep with the side-track you opened:

I wouldn't complain about Tbps, because I know it’s the vernacular, and maybe I 
shouldn’t have mentioned the correct scientific notation, because even much of 
the science in this space is written up in vernacular.

I work with networks that offer a sustained data rate of 2-200 mbit/s (yes, 
millibit per seconds), so I really can’t find a lot of value in using the wrong 
case for the prefixes.  You don’t easily find a press release with “tbps” 
(well, maybe with tbsp, table spoons).  If it rocks your boat, nobody will stop 
you from writing that way, and the trade press in UK/AU really seems to like 
that (did I say anything about competence signaling yet?).

I know most people here don’t care (because they don’t have to(*), literally), 
but there are standards for these things, and there are reasons for the way 
that they have turned out to be.  If you want to taste a little treatise from 
engineers who do care (because their job is building things that measure), you 
can look up https://u.nu/correct-units .

Can we now return to spam-bashing?

Hi Carsten,

You must be talking the "new" comm-speak because "bps" has been the
conventional abbreviation for "bits per second" since at least the
modem days of the 1980s with the "thousands" modifier typically
offered lower case so as not to distract from or be confused with the
digits: kbps, mbps, gbps, tbps. The lack of a space between the digits
and letters also follows convention.

There's nothing wrong with saying "8 Tbit/s" instead. It's just as
clear and no one sensible cares. But complaining about others using
the normal convention frankly makes you look like a doofus.

Competence signaling: technical competence very low.

I don’t expect the majority of nanog people to know the intended data rate 
would properly be notated as 8 Tbit/s, but a space after the number, an upper 
case T, and not confusing Tera (SI prefix for 1 Trillion) with Terra (earth), 
is about the minimum I would expect from a technical person.

With that, we return to the regular spam bashing.

That's the worst argument against this.  Of course you can opt out;
don't use the cable company's box.  And adding an extra SSID to an
already-operating access point (and additional traffic when it used) is
going to be difficult to even measure as a power utilization difference.
If it increased power by an average of one watt (which I really doubt
it'd be that high), that's less than 7 cents per month where I live.

Power consumption is going to be miniscule, especially if the consumer 
opts to use the cable company's built-in wi-fi themselves. If someone is 
really that concerned about their electric bill they can unplug it when 
not in use. Not practical if there's an ATA in it used for landline or 
you have devices requiring Internet access 24/7 like security systems or 
IoT. Of more practical concern is RF interference.


Typically the cable company puts their box in a convenient location for 
access, either near where the cable comes in to the house or maybe 
behind the TV. This often isn't the best place for radio coverage but 
can create strong interference near the box.


If the customer doesn't use the cable box's wi-fi and installs their own 
access point(s), there is no convenient way for them to turn off this 
functionality. Many customers don't even know it exists. Most front-line 
cable support techs don't either.

Calix has this option on the 844G/E CPE. The G is used with fibre based
drops and the
E is used with cable modems.

It is called Community Wifi and is an option that can be enabled in both
units. It uses GRE tunnels
to backhaul traffic.

Never used it so have limited knowledge on actual workings, but have
deployed many
of both types of CPE's.



 

RE: Cable Company Hotspots

[Steven Shalita via NANOG]

That is how Comcast (in the US) does it.  They have a single gateway that
provides the subscriber services and then allows a public hotspot.  Various
levels of authentication are used so only “customers” can access via their
login, or truly public.  They have different QoS for the “subscriber” and
hot spot.In business environments they do the same ting, splitting the
business customers gateway into the customer and the hotspot traffic.



Now not sure about how this might be for Europe with local regulations, but
technically it is done all the time.

How do the cable companies generally deliver this service? A friend insists
it piggybacks off the WIFI radios of existing cable company subscribers. In

Rod, that’s exactly how they are delivering it. Unclear wether it’s over a 
separately provisioned bandwidth channel, or wether it shares the aggregate 
capacity of the HFC.

I tend to agree, as the only hotspot service, customer CPE is generally 
inadequate.  However it can be a nice supplement, and some carriers are now 
experimenting with unlicensed CBRS chipsets in their CPE as well.

Re: Apple Catalina Appears to Introduce Massive Jitter - SOLVED! - Update!

[Mark Tinka]

So after installing Little Snitch and basically denying "trustd" any 
kind of Internet access, I have been seeing reasonably normal jitter 
with Bluetooth enabled.


It's not that Bluetooth stops scanning, but it's not scanning as 
aggressively. So after a few minutes, there will be very high jitter 
when Bluetooth scans the environment, but it would affect only a single 
packet. It's easily reduced its chattiness by 99%.


I don't have any empirical data to support the claim that Little Snitch 
has anything to do with it (and I am too lazy to dig further into it), 
but the reduction in jitter is massively noticeable since Little Snitch. 
Which means I can now run Catalina with Bluetooth enabled and not have 
any wi-fi problems.


Just FYI, for the archives :-).
