These are 900MHz cordless phones. Their website claims up to 3,000 acres coverage in an open area, which is almost 4.7 sq miles. Do these meet Part 15 requirements?
Scanner Tales: Is that a cordless phone or a high-power repeater usurper?

Which model?
I looked at a couple on https://www.engeniustech.com It says FCC and IC certification but no FCC IDs given.
Spec says 902-928 MHz, frequency hopping TDMA, MSK modulation, base and handset power output varies from 20 dBm to 27 dBm (100 mW to 501 mW)
I honestly did not look that closely at the models. However, there was one with a claimed range of 10 acres and another with a range of 3,000 acres. At those power levels, they probably do meet Part 15. 100mW certainly would.
I think the old 46MHz cordless phones put out 100mW, as did the 49MHz HT's which shared the same channels as the cordless handsets and baby monitors.

I have an older 1x that puts out 800mW. I got it with the extra antenna set. 30feet of LMR400 and 6DBI antenna for the base and a 6 inch HT like antenna for the handset. The roof antenna is in storage after moving and I just have the base duct taped to the ceiling with it's back of set antenna, still works great around the neighborhood and surrounding area but I don't have the around town coverage anymore like I used to but it still works great.
Impressive results. The majority of people won't go so far as to install an outdoor antenna. Still, the coverage sounds decent enough with just the built-in antenna.
I got an Engenius phone when in the USAF... we were having trouble communicating about maintenance stuff with people that didn't listen to radios (at least OUR radios) dillegently. I got it with a small discone that I was able to mount on top of a building in the middle of the airfield so that we ( I ) could call any of the users of the equipment that we were working on, to make sure everything was correct. Specifically an airbases windsets and transmissometers.
We needed to make sure that everyone was getting the same readings (ATC tower, RAPCON, and weather station). It was WAY better than the alternatives at the time (no repeater for us).
Back in the mid-60s, I was selling racing slicks in Wichita. I was trying to use CB as a means of communications. That was like nailing Jello to a tree. I went to a local 2-way radio business, as they called it then, and got one of those "cordless phones." It worked well but it was almost as bad as CB because everyone knew your business. That didn't last long either because I was about to get drafted so I joined the Air Force. Sixty years later and I'm still using a cordless phone, of sorts.
The unicode doesn't parse correctly. Is that a roll eyes? LOL
