It was back in the 1980s one day I was talking to a guy on the phone and he said he was talking from his car on a highway. This was before cell phones were popular. He claimed he was using a wireless phone with the base unit back at his house with “an added length of antenna” and he said he bought it at Walmart.
I went and bought the same phone and it was a very ordinary type of wireless phone at the time, I never tried calling anybody from the car.
There was a base unit that plugged into the landline and a handset with a whip antenna on top. Half the call went up around 46mHz, the other half was down above the AM band, maybe in the 1600s (probably before the x-band).
It was kind of convenient when I wanted to walk away from the desk or outdoors, but that unit died and now it’s 2012.
What is the current state of the art of similar wireless phones? I assume they are digital now, if they exist at all. I’m bringing it up here before I go browsing to see what’s out there.
These type phones are likely Part 15 devices.
