Friday Fun: BBC Radio Broadcast of Neuromancer by William Gibson

William Gibson helped create most of the lingo we use today when discussing internet things like hackers or cyber-security. Neuromancer was an influential novel for this author, and it’s a fun trip visiting this BBC radio play. Two hours in length, it’s abridged, but a surprisingly effective re-telling of a classic sci-fi novel. Check it out over the weekend, or during the holidays. Not bad for a freebie!

Review: ETON FRX3 Emergency Radio & Cell Phone Charger – Hand Crank & Solar Powered!

vlcsnap-2013-12-16-09h49m37s95_resultYou folks should know by now how much I like tech designed for active outdoorsy lifestyles, and gadgets which fulfill specific functions.

I was really happy to get my hands on this emergency radio from ETON, as I happen to live in an earthquake prone state, and it looked like a great addition to my emergency kit. There’s a PLETHORA of ways to power this little audio box: AAA batteries, a rechargeable battery pack, solar power, and a hand crank! Plus you can use it to recharge your phone!

Let’s take a look at the FRX3!

Galaxy Note 3 first to feature new Qualcomm Radio Power Management. More run time, less heat.

For all of our criticism surrounding powerful quad-cores, throw your phone into airplane mode, and it’s shocking how long that quad can run. We can only pack in SO much battery density, and the rest of your phone can be surprisingly frugal, which is why developments in radio management are so crucial to improving the smartphone experience.

Qualcomm has been working on Envelope Tracking for their LTE radio technology. To over-simplify, LTE is a little different in how it communicates with cell towers than 3G, which in the past has made it more difficult to adjust the power of the radio in your phone while maintaining a stable connection to a tower. Essentially, your phone’s radio tries to find an average signal to broadcast at, but often just runs at max on LTE, which is pretty terrible for battery life, and can sometimes result in a poor connection.

As the radio is working a brute force style signal, it should greatly reduce the amount of power needed to run, which should also cut back on wasted heat. Qualcomm is estimating a 20% reduction in power and a 30% reduction in heat generated by the radio. This should also provide a more stable link to the tower, hopefully resulting in faster throughput.

Now normally when we write up new tech like this it’s usually an article about researchers in a lab, and we’ll all have to wait for the breakthrough to eventually filter down into our actual consumer devices. The nice thing about Qualcomm’s ET gear is it’s already going to be included in the Galaxy Note 3. Likely one of the reasons Samsung went with Qualcomm’s 800 series chipset for its LTE variants of the note.
