The US interior department’s decision not to buy more drones with Chinese parts has made it more difficult to fight wildfires, according to an internal departmental memo, which lays bare one cost of the Trump administration’s crackdown on Chinese technology.

The memo, which was written by the department’s Office of Aviation Services earlier this year, found that by the end of the year, the department will have carried out only a quarter of the controlled burning it might otherwise have done had it gone ahead with planned drone purchases.

The US is experiencing one of its worst years for wildfire outbreaks thanks to hot weather and a lack of firefighters. And while none of those appear to have happened on federal land, government insiders warn the de facto ban on buying drones with Chinese components risks making the situation worse.

Qualcomm's push for 5G will soon hit some of the cheapest phones on the market. Today, the company announced 5G is coming to the Snapdragon 4-series in "early 2021."

Qualcomm says the goal of these chips is to enable "5G for everyone," and the chips will show up in phones ranging from $125 to $250. The 4 series is where Qualcomm's mass-market sales really happen, and the company says it will be able to reach 3.5 billion smartphone users with these new chips. The only cheaper chips in Qualcomm's lineup are the 2 series, but those phones make up the bargain-basement $100-and-below market and are actually pretty rare.

"5G" here most likely means sub-6GHz 5G, which is cheaper to implement than the faster mmWave 5G. mmWave requires several additional antennas in the phone due to its poor signal penetration. Your hand will block the signal, so the solution to that is multiple antennas that work around your hand position. Sub-6GHz 5G has much better signal characteristics and has a shot of a wide rollout. mmWave is responsible for any of the 5G speed test records you see—and all the advertisement talk of "revolutionary" connectivity—but carriers in the US have said mmWave will be limited to cities because it requires so many towers.
