radios

This is interesting because certain parts of the bandwidth for wifi routers crosses into the bandwidth for amateur radios.

When he visited them, they had large bins of defective car radios that wouldn't turn-on, etc.

Has long irritated me that car audio systems have a discernible boot time, having come from the days of instant-on radios.

This is easy(ish) to do with a mini Arduino and a pair of XBee radios.

But sending out frequency maps is easier when you can limit the number of different radios to just a few authorized vendors.

It's trivial to get miniPCIe cards with the same Atheros ath9k 802.11n radios that are used in the most popular OpenWRT devices.

Galaxy Nexus, Droid Bionic, HTC One X+) married Qualcomm LTE radios with non-Qualcomm SoCs.

With radios it has been that moving for tubes to transistors to ICs has upped the minimum tools needed to get anything done.

None of the radios have their own non-volatile storage for their firmware.

But these so-called infotainment systems, and radios, and communications systems, and satnavs, and fancy environmental controls...

Very interesting hardware; I particularly like the hardware killswitches for the sensors (microphone and camera) and radios (WiFI & Bluetooth).

The argument has always been that it's too difficult to coordinate all the different radios to prevent one accidentally transmitting where it isn't supposed to.

Just wait until the FCC learns about these crazy things call "software defined radios." They'll have to ban antennas outright!

When Mikrotik doesn't sell any devices that have both 2.4GHz and 5GHz radios out of the box, I don't think you can classify them separately from "build your own", unless you want to talk about how their cheap 2.4GHz-only devices stack up against the kind of D-Link devices that they give away for free when you buy a modem.
