Could you put the link on this info, thanks?

Here is a frequency I knew well when I practiced radiotelephony. Now these frequencies are recovered for other applications. :frown:


Ah, so it's not only the CPL for the Linky ... there is a SIM / GSM chip as much in the Linky as the Gazpar too (according to this same page):

The Linky Electricity Meter uses Power Line Carrier (PLC) technology as the first level of data communication to a concentrator: information flows through electrical cables. It does not induce more electromagnetic fields inside the dwellings than current meters. A second level of communication is provided by the mobile telephone network between the hub and the ERDF central system.

The Gazpar natural gas meter transmits the data twice a day, in less than a second, by radio wave, to a concentrator, using a frequency of 169 MHz, close to the frequencies of the FM radio. A second level of communication is provided by mobile telephony between the hub and the GRDF information system.


However all the "neuneus du net" complain about the CPL ... yet much less harmful than the GSM ... am I wrong?

Would surprise me that a battery in the gaspar lasts 20 years for that ... especially if the meter is subjected, installed outside, to the variations of temperature and humidity ...

Instead of fishing more or less reliable info here or elsewhere on the web ... here is what the wiki page says:

https://fr.wikipedia.org/wiki/Gazpar

Not too much information on communication, so here: https://fr.wikipedia.org/wiki/Compteur_communicant

The page on the linky is more complete level communication: https://fr.wikipedia.org/wiki/Linky#Technologie

Linky meters use line power lines (PLC) on the low voltage network4. This technology makes it possible to build a computer network on the electrical network of a home or an office, or even a neighborhood or group of offices.

However, the PLC technology is subject to public concern about the possibility of safety risks due to the radio frequencies used, as the electrical network has the side effect of acting as an antenna.

In parallel, a second level of communication is provided by the GPRS Edge4 mobile network between the hub (installed in a HTA / BT5 transformer and distribution substation) and the central system. This technology is an evolution of GPRS which is itself an extension of GSM with backward compatibility. It is often used in addition to a UMTS network to offer broadband services to more users in rural or suburban areas. rather than those in urban areas

An "interesting" info on the gazpar wiki page:

Cost

According to various projections and provided that the initial budget is kept, the additional cost for the consumer could amount to 2 or 3 € on the annual gas bill., an overall increase of 0,3%. This slight increase is likely to be offset, in whole or in part, by the energy savings made possible by Gazpar.

if the gas goes, it's more of a loss than an economy!

No the linky is only CPL, the concentrator can be 800 m

It takes little energy to transmit a frame to 169 Mhz and 1km, although 20 years, the battery may be worn even without serving.

Someone had talked about RFID, it's a short-range technology.

The mode of feeding gaspar or linky do not appear in the links you give us, Christophe.

like?

Yes that was the meaning of my remark: I do not believe that there are batteries on Earth that retain their original charge 20 years maintenance-free ... even less if they are subject to changes in temperature and humidity (a lot of gas meters are outside ...)

Yes, it remains "mysterious" concerning gaspar so ... but for the Linky we know ...

No doubt about the fact that gaspar does not need to be powered, but for the operation I would rather look for the Gaston solution.

They kept a mechanical meter, why not at the same time cause a small generator that would recharge a battery and blows, autonomy is assured.
