Broadcom introduces low-power WiFi and Bluetooth chips for the Internet of things

The Internet of things -- that nebulous term usually associated with interconnecting everyday objects in a meaningful way -- is in the news again. Yesterday, Broadcom announced that it's launching a couple cost-effective, power-efficient wireless chips geared towards appliances, home automation and wearable devices. The first SoC, BCM4390, incorporates a highly-efficient WiFi radio for embedded use in products such as weight scales, thermostats and security cameras. It fits into the company's range of Wireless Internet Connectivity for Embedded Devices (WICED) chips. The second SoC, BCM20732, features an ultra low-power Bluetooth transceiver and targets devices like heart rate monitors, pedometers and door locks. Broadcom's also contributing its Bluetooth software stack to the Android Open Source Project with support for both standard and Bluetooth Smart hardware. Does this mean our long-awaited smart toaster's just around the corner? We sure hope so. Follow the source links below for more info.

Google outs new Maps and Location APIs: geofencing and low-power location services

Google outs new Maps and Location APIs: geofencing and low-power location services

Maps is one of the most useful features in Android, and today at Google I/O 2013, Mountain View announced a trio of new location services APIs to help devs to better leverage that strength. Fused Location Provider is the first, and it brings faster, more accurate location signals and delivers a low-power location mode that sips less than 1 percent of your battery while in use. Next is Geofencing, which will allow devs to set up to 100 location-based triggers for app events. The third API is called Activity Recognition, which uses accelerometer data and machine learning to figure out when you're walking, cycling or driving.

Acer unveils space-saving ME mini tower and XC desktops for (low) power users

Acer refreshes

The arrival of Windows 8 is a good excuse for the PC industry to flood the market with so much hardware, consumers will be blinded by so much choice. Acer's jabbing its digits into your eyes with its new lineup of low-end desktops for the casual user. The ME micro towers will take an Intel Core i5 or I7, 2TB HDDs and up to 16GB of RAM. If you don't have anywhere else to stash your smartphone, the chassis comes with a recess desk on top with a USB port for easy charging. Those looking for something a little less demanding can pick up an XC desktop, a space-saving unit that will take an Intel Core i3, a 1TB HDD and up to 6GB of RAM. Prices for the ME begin at $700, while the cheaper XCs will set you back a much more modest $400.

Facebook to backup its servers with low-power storage devices at ‘Sub-Zero’ data center

Facebook to backup its servers with low-power storage devices at 'Sub-Zero' data center

Data backups come in all shapes and sizes. For some, they take the form of external hard drives or a slice of the amorphous cloud. As for Facebook, its upcoming solution is low-power deep-storage hardware contained within a 62,000 square-foot building in Prineville, Oregon near its existing Beaver State data center. Unofficially referred to as "Sub-Zero," the facility will store a copy of the social network's data in case its primary servers need to be restored in an emergency. Rather than continuously power HDDs that are only occasionally used, the new setup can conserve energy by lighting-up drives just when they're needed. One of the company's existing server racks eats up around 4.5 kilowatts, while those at Sub-Zero are each expected to consume approximately 1.5 kilowatts once they're up and running. Tom Furlong, Facebook's vice president of site operations, told Wired that there are hopes to create a similar structure alongside the firm's North Carolina data center. Since the Prineville project is still being planned, Zuckerberg & Co. have roughly six to nine months to suss out all the details before your photos are backed up at the new digs.

Ask Engadget: Best sub-$310 power-efficient HTPC for a caravan?

Ask Engadget: Best sub-$310 power-efficient HTPC for a caravan?

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is coming to us from Is from Martin, who is looking for a hyper-efficient media streamer for his retro caravan. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"My partner and I are renovating a small '70s caravan and would like a power-efficient media center/PC purely to watch our library of movies and TV shows. We're in Australia, so getting hold of kit like the Raspberry Pi would be difficult, we're looking for something that's equally power efficient, even up to $300 AUD (around $310 USD). Cheers!""

That's this week's challenge, Engadgeteers -- do you feel up for it? Can you help our southern hemisphere friends find a power-efficient HTPC for under $310 that won't drain a retro-caravan's batteries? Can we help these people turn the temporary home into a rockin' media-streamin' paradise? Hit us up in the comments if you've got some expertise to share.

Samsung mass-produces 4-gigabit LPDDR2 memory, aims to make 2GB a common sight in smartphones

Posted on by

Samsung started making 2GB low-power mobile memory last year, but as the 1GB-equipped phone you likely have in your hand shows, the chips weren't built on a wide-enough scale to get much use. The Korean company is hoping to fix that now that it's mass-producing 20-nanometer, 4-gigabit LPDDR2 RAM. Going to a smaller process than the 30-nanometer chips of old will not just slim the memory down by a fifth, helping your smartphone stay skinny: it should help 2GB of RAM become the "mainstream product" by the end of 2013, if Samsung gets its way. New chips should run at 1,066Mbps without chewing up any more power than the earlier parts, too, so there's no penalty for using the denser parts. It's hard to say whether or not the 20nm design is what's leading to the 2GB of RAM in the Japanese Galaxy S III; we just know that the upgraded NTT DoCoMo phone is now just the start of a rapidly approaching trend for smartphones and tablets.

Panasonic preps samples of next-gen ReRAM devices, NAND preps for early retirement

The Galaxy S III may rock an impressive battery life, but if Panasonic has its way, even greater benchmarks could be on the horizon. The company is ready to start making samples of a new ReRAM microcontroller, and -- like Sharp and Elpida -- it could start mass production as soon as next year. Here's a little refresher: ReRAM is a new kind of memory with re-write speeds far superior to NAND because it doesn't need power to hold onto information. Panny's chip will initially be used in simple devices like fire alarms, but the tech could eventually find its way into our TVs and even smartphones and tablets. But seriously, are we even capable of living in a NAND-free world?

Series revisits ARM's humble beginnings, BBC Micro and all

If you read our interview with ARM co-founder John Biggs, you know the company behind the processor in most smartphones had quite modest beginnings, what with an office in a barn and all. But Biggs is only part of the story, and Reghardware fleshes the rest out with a two-part series on the "unsung heroes of tech": Sophie Wilson, Steve Furber and Herman Hauser, the team behind Acorn Computers, the British PC company that spawned ARM in the mid-80s. We'll let you click through to the source links to take the journey yourself, but here are a few highlights: earning a computer contract with the BBC, happening upon ARM chips' low power consumption by accident and striking gold thanks to a partnership with Apple.
