my apologies. you are correct.

Cat-M1 will deploy the bandwidth of 1.4MHz (including guard interval).
Cat-M2 will use 200kHz (including guard interval).

Bandwidth M2

I guess the BW of M2 is 200KHz and not 200MHz.

@jzws, you are absolutely right. The $7-$8 price range provided by Sequans for M1 is referred to M1 "module," not a chip price. My bad. The story is now corrected. Thanks for your eagle eye!

Hi, Rick. No, that is not the case. As you previously reported, the industry group standardized Cat-0, but nullified it last fall -- meaning no carriers will go for it. The key differece, among other things, is that Cat-0 was based on "wide band" but both Cat-M1 and M2 are moving to "narrowband." So this ain't simple re-naming or facelifting. We'll see if we can find out more on their power consumption front.

Interesting, maybe even risky approach, introducing chipsets before the standard has been fully bedded down. And for the kinds of applications targeted, $7 or $8 for the Cat M1 chipset seeems a bit high -- perhaps for the module, that may be in the right ball park.

I wonder the extent to which this is just renaming what was going to be Cat-0 as Cat M and what was to be Cat M as M2 because the timeframes and specs sound similar.

Also any data on expected average power consumption especially vis-a-vis the LPWA altetrnsatives (Sigfox, LoRa, Ingenu, etc).
