HDBaseT takes HDMI and 4K further

All HDMI cables are the same, but that now-ubiquitous connector has limitations. Ultralong runs can be problematic and expensive, HDMI cable can't conveniently be run through walls, and when carrying 4K video, it can only handle runs of a few feet.

That's the message the people from HDBaseT sent when they introduced me to their transmission protocol this week. HDBaseT is designed to allow a single Cat 5e cable -- incredibly common and incredibly cheap today -- to carry video of up to 4K resolution, audio, data (100BaseT Ethernet), power (up to 100 watts), and even other signals … Read more

Wi-Fi Alliance launches 802.11ac certification program

The new 802.11ac Wi-Fi standard can't get more official than this.

The Wi-Fi Alliance today launched its Wi-Fi Certified ac certification program, paving the way for the new standard to be easily adopted and interoperate among different hardware vendors.

This is significant since the new standard offers up to three times the wireless speed of the existing and ever-popular Wireless-N (802.11n) standard, enabling support for even the most demanding applications such as Ultra HD, 4K video, multimedia, and fast file data transfer within the wireless home network.

According to the Wi-Fi Alliance's recent poll, the number … Read more

AMD unveils first eight-core 5GHz processor

If there were a clock speed war going on, AMD would win again.

The chip maker unveiled today the most powerful member of the AMD FX family of CPUs, the eight-core AMD FX-9590, which it claims to be world's first commercially available 5GHz processor.

Back in 2000, AMD was the first to break the 1GHz barrier by delivering its 1GHz Athlon chip to the general public in May of that year. The FX-9590 will be available this summer and Intel has until then to unveil its own 5GHz CPU. Currently the fastest CPU from Intel is the 3.5GHz … Read more

Broadcom brings Gigabit and Wi-Fi to power line networking

Power line networking -- the technology that enables electrical wiring to transfer data -- is about to get a lot faster.

Broadcom announced on Monday what it claims to be the industry's first HomePlug AV2 power line system-on-a-chips (SoCs) that deliver up to 1.5Gbps data speed. That's about three times the speed of the top existing power line devices.

HomePlug AV2 is the next-generation power line standard that uses an extended frequency band of up to 86MHz, while HomePlug AV was limited to 30MHz. In addition, HomePlug AV2 supports Multiple Input Multiple Output (MIMO) -- a technology … Read more

Quantenna's new chip turns 802.11ac Wi-Fi up a notch

There's more to 802.11ac than we've seen so far.

Quantenna Communications announced today the first 802.11ac chipset, called QSR1000, with a ceiling speed of up to 1.7Gbps, which is 400Mbps faster than the current cap of any 802.11ac router, such as the Asus RT-AC66U or the Trendnet TEW-812DRU.

The QSR1000 achieves this new speed by supporting the new 4x4 MU-MIMO 802.11ac standard. In other words, it's the first quad-stream Wi-Fi chipset. Up to now, all existing Wi-Fi devices have only used a single-stream, dual-stream, or three-stream setup. (Read more about Wi-Fi standards here.) … Read more

Home networking Part 7: Power line connections explained

Editors' note: This post is part of an ongoing series. For the other parts, check out the related stories section below.

Power line networking basically turns a building's existing electrical wiring -- the wires that carry electricity to different outlets in the house -- into network cables, meaning they also carry data signals for a computer network. And this means virtually all households, in the U.S at least, are "wired for" power line networking. It doesn't replace a regular network, so you'll still need a router, but it's a good way to extend … Read more

Netgear entices developers with million-dollar app contest

To attract software developers, Netgear today launched its Million Dollar App Contest with the aim of diversifying the company's Netgear Genie+ marketplace. The networking vendor hopes the contest will encourage creation of innovative apps for its routers and NAS servers.

The company says the top three app developers will win a trip to Las Vegas and the winner of the contest will also receive $10,000 with a chance to win a grand prize of a $1 million 40-year annuity, which is to be announced at CES 2014. Participants will also earn revenue by selling their apps through the … Read more

Linksys adds two more Smart Wi-Fi routers to EA series

Linksys announced today that two more Smart Wi-Fi routers have been added to its EA series. This is the company's first product announcement since it was sold to Belkin by Cisco last month.

The two new routers are the Smart Wi-Fi Router AC 1200 Advanced Multimedia (model EA6300) and the Smart Wi-Fi Router AC 1600 Video Enthusiast (model EA6400).

Both of these routers are true dual-band and support the 802.11ac Wi-Fi standard on the 5GHz band. Late last year, Linksys began shipping the Smart Wi-Fi Router AC 1750 HD Video Pro (model EA6500), and it's still the … Read more
