For their new wireless adapter Rivet Networks has partnered with Intel, producing "the worlds fastest 2x2 11ac wireless networking adapter" in the Killer Wireless-AC 1550. This new adapter supports the 802.11ac Wave 2 standard and offers up to 1.73 Gbps throughput using 160 MHz channels.
"The first product to come out of Rivet Networks’ new partnership with Intel, the Killer™ Wireless-AC 1550 is the world’s fastest 2x2 11ac wireless networking adapter. The Killer Wireless-AC 1550 has been designed to combine the speed, intelligence, and control of Killer Networking products with the power and performance of the latest Intel wireless chipset. Delivering faster than gigabit Ethernet speeds along with the gaming functionality that gamers love, the Killer 1550 is the ideal wireless networking product for competitive gamers and performance users who demand the most from their computers."
Killer Networking lists these features for the Killer Wireless-AC 1550:
- Gigabit Wi-Fi Speeds: The Killer Wireless-AC 1550, featuring 160 MHz channel support, has a theoretical max throughput speed of 1.73Gbps when connected to a router that supports 160 MHz channels. This is faster than gigabit Ethernet and twice the speed of standard 2x2 11ac products.
- MU-MIMO Support: Killer 1550 includes full MU-MIMO (Multi-User-Multiple Input and Multiple-Output) support, which dramatically increases network efficiency by working with a MU-MIMO enabled access point. MU-MIMO allows wireless access points to support multiple transmissions at the same time, versus a single transmission at a time like normal access points. This creates additional efficiencies that can provide up to 60% faster download speeds, lower latency, and a better overall connection.
- Transmit Beamforming Technology: Killer 1550 also has Transmit Beamforming technology, which allows the Killer Wireless-AC 1550 to share location information directly to your wireless access point so that the access point can better direct its signals to you. This creates stronger wireless signals at all ranges and faster data transfers.
- Complete 802.11ac functionality: Supports dual band (2.4 GHz and 5GHz), IEEE standards-based 802.11a/b/g/n/ac, and includes Bluetooth 5.0 connectivity.
While the big news might be the Intel co-developed hardware, as this is a Killer Networking product the software is a big component in the overall experience. Options configurable via the Killer Control Panel include Advanced Stream Detect 2.0 for automated traffic prioritization for games and streaming, along with Lag and Latency Reduction Technology and Killer DoubleShot Pro support.
The first devices with the new Killer Wireless-AC 1550 adapter are being released this month.

Corsair continues the expansion of their peripheral portfolio at CES, and the focus here is wireless. The new products include a new wireless keyboard and mouse (Corsair's first wireless mouse) along with a Qi wireless charging mousepad and new lap board.
K63 Wireless Mechanical Gaming Keyboard
First up is the K63 keyboard, a wireless TKL design with a trio of connection options. In addition to Corsair's 2.4 GHz connection which offers 1 ms latency, there is also the option of connecting via Bluetooth 4.2 (with a latency of 7.5 ms) or use a standard wired connection via USB (which also charges the keyboard).
The K63 keyboard has Cherry MX Red key switches (no option for other colors, currently), individual backlighting, and battery life that ranges from 15 hours of continuous use with default backlighting (default brightness is 66%), up to a whopping 75 hours of continuous use without backlight. AES 128-bit encryption is also supported, and for gamers who do not want the additional latency this adds (total of 1.08 ms), encryption can be toggled on and off via software.
DARK CORE RGB Wireless Mouse
Corsair's first wireless mouse offers the same three connectivity options as the K63 keyboard, with 2.4 GHz or BT 4.2 wireless in addition to USB, and there is an SE version of the mouse that also supports the Qi wireless standard with its integrated charging coil, and that is complimented by the MM1000 Qi wireless charging mousepad.
Not only did Corsair announce the new keyboard and mouse, but also the K63 Lapboard for your slick new wireless peripherals. It's a lightweight design that features memory foam padding and a built-in wrist rest, and the mouse pad is removable for cleaning/replacement.
All of these new wireless peripherals and accessories are available now, with pricing as follows:
- Dark Core RGB Mouse: $79.99
- Dark Core RGB SE Mouse: $89.99
- MM1000 Qi Wireless Charging Mousepad: $79.99

On the opening day of Qualcomm’s Snapdragon Tech Summit, the company brought AMD on stage and announced a partnership that would see AMD use Qualcomm’s Snapdragon LTE modems alongside Ryzen Mobile SoCs to enable always connected Windows devices.
PC Perspective’s Ryan Shrout and Ken Addison attended the event and gleaned a few more details about the announcement. According to Ryan on the podcast, AMD plans to use Qualcomm’s Snapdragon LTE modems in Ryzen Mobile-powered laptops and tablets. While road warriors will be able to enjoy cellular connected AMD laptops, Ryan notes that these devices may not support the new “connected standby” standard where a Windows PC is able to keep the cellular connection and the PC in a very minimal power state to download notifications, emails, and other updates in the background while the PC is otherwise sleeping.
Reading this announcement piqued my interest though for the future of this partnership. While the first devices are likely to include the Qualcomm modem on the motherboard, in the future AMD may be allowed to integrate the modem into its mobile APUs which would help AMD to compete with Intel in this space. Qualcomm is a big player and could give AMD a strong and competitive wireless solution without AMD having to navigate the murky patent waters and huge R&D costs involved with coming up with its own in-house modems.
What are your thoughts on this Qualcomm and AMD partnership?

Rivet Networks has a new Killer Networking product, but it isn't a line of NICs or Wireless adapters; it's actually a combination of both interfaces (including a minimum of three Gigabit Ethernet ports) that combine to turn your PC into switch and a Wi-Fi extender. They call the new product Killer xTend, and Rivet Networks has partnered with MSI and GIGABYTE to bring the new technology to market.
"Killer xTend delivers powerful network extension capabilities to your computer by integrating a network switch that includes at least three Killer Ethernet ports and using a Killer Wireless-AC module as a Wi-Fi extender. This allows your computer to share its network access with other nearby wired and wireless devices with a strong, powerful network connection.
Consumers no longer need to mess with switches and network extenders that are expensive and difficult to configure. Instead, they can use Killer’s innovative new xTend Technology to connect devices such as gaming consoles, smart phones and tablets directly to their gaming PCs. Killer xTend keeps your games, voice, and video fast and smooth because high priority traffic on the Killer PC is prioritized above the traffic from connected devices. Killer xTend also delivers amazing speeds – with potential throughput up to 1 Gbps for each Killer E2500 plus another 867 Mbps for the Killer Wi-Fi module."
The first motherboard launching with Killer xTend is the MSI Z270 GODLIKE GAMING, with three Killer E2500 NICs and a Killer Wireless-AC 1535 module onboard.
"...the new GODLIKE adapts the Killer™ xTend technology as well and delivers powerful network extension capabilities by integrating a network switch that includes 3 Killer Ethernet ports and a Killer Wireless-AC module as a Wi-Fi extender. This allows the GODLIKE GAMING to provide the network access to other nearby wired and wireless devices with a strong, powerful network connection. Gamers no longer need to mess with switches and network extenders that are expensive and difficult to configure – instead they can use Killer’s innovative new xTend Technology to connect devices such as gaming consoles, smart phones, and tablets directly to your gaming PC. The Killer xTend keeps your games, voice, and video fast and smooth because high priority traffic on the Killer PC is prioritized above the traffic from connected devices. Killer xTend also delivers amazing throughput to your home – with potential throughput up to 1 Gbps for each Killer E2500 plus another 867 Mbps for the Killer Wi-Fi module."
GIGABYTE's AORUS Gaming Series will include Killer xTend, though no specific models were mentioned in the press release from Rivet Networks.

Introduction and Specifications
The G533 Wireless headset is the latest offering from Logitech, combining the company’s premium Pro-G drivers, 15-hour battery life, and a new, more functional style. Obvious comparisons can be made to last year’s G933 Artemis Spectrum, since both are wireless headsets using Logitech’s Pro-G drivers; but this new model comes in at a lower price while offering much of the same functionality (while dropping the lighting effects). So does the new headset sound any different? What about the construction? Read on to find out!
The G533 exists alongside the G933 Artemis Spectrum in Logitech’s current lineup, but it takes most of the features from that high-end wireless model, while paring it down to create a lean, mean option for gamers who don’t need (or want) RGB lighting effects. The 40 mm Pro-G drivers are still here, and the new G533 offers a longer battery life (15 hours) than the G933 could manage, even with its lighting effects disabled (12 hours). 7.1-channel surround effects and full EQ and soundfield customization remain, though only DTS effects are present (no Dolby this time).
What do these changes translate to? First of all, the G533 headset is being introduced with a $149 MSRP, which is $50 lower than the G933 Artemis Spectrum at $199. I think many of our readers would trade RGB effects for lower cost, making this a welcome change (especially considering lighting effects don’t really mean much when you are wearing the headphones).Another difference is the overall weight of the headset at 12.5 oz, which is 0.5 oz lighter than the G933 at 13 oz.

Forget LiFi, Firefly uses infrared lasers to transmit data and torture acronyms. Researchers out of Penn State, backed by Microsoft, are working on a way to get rid of the wiring in your server room and replace it with IR lasers and mirrors; hold the smoke. By using multiplexed beams, they have created a proof of concept test which allows bi-directional data streams at 10 gigabits per second though there is some work to be done before it is ready for a full test.
The mirrors would be MEMs controlled, ensuring that the signal should theoretically be able to reach any receiver, even ones obscured by other equipment. Anyone sick of cable management or looking for new ways to keep people out of the server room can take a peek at the link to the research that The Register posted. On the other hand, the simple act of walking into your server room, setting down a box or even a leaf on the wind would be likely to cause downtime. Could protective goggles might be the newest sysadmin fashion faux pas?
"Shown off at Photonics West 2017 in San Francisco, Firefly (acronymically tortured out of Free-space optical Inter-Rack nEtwork with high FLexibilitY, we kid you not) proposes FSO to provide multiple 10 Gbps inter-rack links."

Bluetooth has come a long way since the technology was introduced in 1998. The addition of the Advanced Audio Distribution Profile (A2DP) in 2003 brought support for high-quality audio streaming, but Bluetooth still didn’t offer anywhere near the quality of a wired connection. This unfortunate fact is often overlooked in favor of the technology's convenience factor, but what if we could have the best of both worlds? This is where Qualcomm's aptX comes in, and it is a departure from the methods in place since the introduction of Bluetooth audio.
What is aptX audio? It's actually a codec that compresses audio in a very different manner than that of the standard Bluetooth codec, and the result is as close to uncompressed audio as the bandwidth-constrained Bluetooth technology can possibly allow. Qualcomm describes aptX audio as "a bit-rate efficiency technology that ensures you receive the highest possible sound quality from your Bluetooth audio device," and there is actual science to back up this claim. After doing quite a bit of reading on the subject as I prepared for this review, I found that the technology behind aptX audio, and its history, is very interesting.
A Brief History of aptX Audio
The aptX codec has actually been around since long before Bluetooth, with its invention in the 1980s and first commercial applications beginning in the 1990s. The version now found in compatible Bluetooth devices is 4th-generation aptX, and in the very beginning it was actually a hardware product (the APTX100ED chip). The technology has had a continued presence in pro audio for three decades now, with a wider reach than I had ever imagined when I started researching the topic. For example, aptX is used for ISDN line connections for remote voice work (voice over, ADR, foreign language dubs, etc.) in movie production, and even for mix approvals on film soundtracks. In fact, aptX was also the compression technology behind DTS theater sound, which had its introduction in 1993 with Jurassic Park. It is in use in over 30,000 radio stations around the world, where it has long been used for digital music playback.
So, while it is clear that aptX is a respected technology with a long history in the audio industry, how exactly does this translate into improvements for someone who just wants to listen to music over a bandwidth-constrained Bluetooth connection? The nature of the codec and its differences/advantages vs. A2DP is a complex topic, but I will attempt to explain in plain language how it actually can make Bluetooth audio sound better. Having science behind the claim of better sound goes a long way in legitimizing perceptual improvements in audio quality, particularly as the high-end audio industry is full of dubious - and often ridiculous - claims. There is no snake-oil to be sold here, as we are simply talking about a different way to compress and uncompress an audio signal - which is the purpose of a codec (code, decode) to begin with.
