ASUS has just announced the HiveSpot and HiveDot Mesh WiFi systems, which both combine multiple access points into a single network. Any individual node could be configured as either a router or a repeater, but the system is designed around one acting as a router and the rest, repeaters. The main difference between the two models is the higher-end set, the HiveSpot, utilize an extra, 5 GHz band, running 867 megabit, that’s dedicated to communication between the access points.
Because of this, the HiveSpot is listed as AC2134 while the HiveDot is AC1300, but devices that connect to this network will see two, 650 megabit bands in either case. What the HiveSpot will get you is higher performance (and maybe stability) should multiple devices be communicating with different nodes at the same time. With the HiveDot, the routers will be sharing the same bandwidth as the devices connecting to them.
ASUS wasn’t too clear about pricing in their press release, but CNet is reporting that they will be sold in bundles of three, which is the minimum for the mesh network. Three HiveSpot devices will carry an MSRP of $399 USD, while three HiveDots, $299. In other words, it will cost you $100 if you want the high-bandwidth, dedicated link between the nodes.

Lenovo is announcing a trio of new connected devices beginning with the Amazon Alexa-powered Smart Assistant.
“The Lenovo Smart Assistant with Amazon Alexa is like having your own digital assistant at home. Featuring Amazon’s Alexa Voice Service, this voice-controlled high-definition speaker with far field microphones, is there to lend a hand whenever you need it. Want to know what the morning traffic is like? Forgot to order that book from Amazon? Longing to hear your favorite playlist? Simply ask Alexa. She has all the answers to help simplify your life. What’s more, she can even help remotely with the Amazon Alexa App, which is free to download for Android and iOS.”
The Smart Assistant offers high definition sound with a speaker system that combines a 5W treble and 10W bass speaker, and the Harman Kardon Edition takes this further with a ported design for enhanced sound.
Next we have Lenovo’s Smart Storage, which provides up to 6 TB of connected storage over a wireless (or wired) home network.
“Despite this remote storage center’s compact size, the Lenovo Smart Storage comes with a big challenge: How will you and your family fill it? Capable of storing up to 6 TB of photos, movies, and other digital files, this dual-band WiFi storage system can connect wirelessly to almost any smart device you own, worldwide. You’ll maintain absolute administrative control, ensuring your data and content are secure and safe—and with Auto Sync enabled, your data will back-up automatically when within WiFi range. DLNA support also ensures you’ll be able to enjoy your movies and music on any device, anytime.”
Finally we have the Lenovo 500 Multimedia Controller, which combines a compact keyboard and touchpad in a small wireless control device for the living room.
“Want to browse the web from your couch? Or turn on your favorite playlist from the dining table? We’ve got you covered with the Lenovo 500 Multimedia Controller. It’s not only a mouse and keyboard in one, it’s also a remote control optimized for your Windows operating system. With an ergonomic design and up to 8 months battery life, the versatile Lenovo 500 Multimedia Controller will make your life easier.”
The controller is designed for Windows PCs (support for Windows 7 through 10), and uses a nano USB dongle for its 2.4 GHz wireless connection. The touchpad DPI is adjustable for user preference, and the unit offers up to 8 months of battery life from a pair of AAA batteries. At 5.71 x 3.37 x 0.74 inches (and 141 grams) this is a pretty small device, but certainly larger than some of the smart TV remote keyboards certain models have shipped with.

Qualcomm has officially unveiled the development of a new 5G modem with the Snapdragon X50, which targets OEMs and early 5G development. The X50 supports milimeter wave (mmWave) technology initially, and rather than replace existing LTE solutions the X50 is designed to work alongside LTE modems integrated into Snapdragon SoCs, for a seamless handoff between 5G and 4G networks.
"The Snapdragon X50 5G modem will initially support operation in millimeter wave (mmWave) spectrum in the 28GHz band. It will employ Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques, which facilitates robust and sustained mobile broadband communications in non-line-of-sight (NLOS) environments. With 800 MHz bandwidth support, the Snapdragon X50 5G modem is designed to support peak download speeds of up to 5 gigabits per second.
Designed to be used for multi-mode 4G/5G mobile broadband, as well as fixed wireless broadband devices, the Snapdragon X50 5G modem can be paired with a Qualcomm® Snapdragon™ processor with an integrated Gigabit LTE modem and interwork cohesively via dual-connectivity. Gigabit LTE will become an essential pillar for the 5G mobile experience, as it can provide a wide coverage layer for nascent 5G networks."
Ratification of an official “5G” standard has not taken place, but Qualcomm hopes to position itself at the forefront of its development. The mmWave technology (which is explained in this video) is only one part of the puzzle:
"Work has begun on defining, standardizing and designing the new OFDM-based 5G New Radio (NR) as part of the global 3GPP standard. 5G NR is being designed to support a wide variation of device-types, services and deployments. It is also being designed to get the most out of every bit of spectrum across a wide array of available spectrum bands and regulatory paradigms."
(More information is available on Qualcomm's 5G Technologies page.)
The Snapdragon X50 modem is set to begin sampling to OEMs in the second half of 2017, with the first half of 2018 projected for the first commercial products featuring the new modem.

Tagged: asus, XG-U2008, unmanaged switch, 10 gigabit
Planning an upgrade to your network or looking to build one that will last into the next generation of NICs? ASUS has just made an unmanaged 10 gigabit switch available at a price far below the average asking price of the devices currently on the market. $250 is still a steep investment for a switch but is less than half of the competitions, albeit without the management features found on those switches. The LEDs on the front will glow amber if the cable you use is not up to the new standard, otherwise expect green for go. It will support Jumbo Frames of up to 16 KB just like the more expensive models. It is a compact 9.44x4.92x1.06", so you should easily be able to find a home for it. PR below the snazzy product shot, technical details from ASUS here.
Fremont, CA (October 10th, 2016) -- Outside the enterprise market, the transition from Gigabit to 10-Gigabit Ethernet has been rather slow. While there are growing small-business and prosumer demands for the additional bandwidth that 10G networking provides, the cost of entry is high. Until now, the availability of compliant devices has been limited to enterprise-class products that are built with corporate networks in mind, with pricing for 10-Gigabit switches starting at $800. That certainly isn’t expensive by corporate standards, but for the rest of us, it relegates adoption to cases of absolute necessity and the upper echelon of enthusiasts.
While it’s advisable to plan ahead and overprovision your network for scalability, paying extra money for ports or features that you’ll never use doesn’t make sense. So, there’s a clear need for 10G networking devices that are suitably tailored for the small business, prosumer, and enthusiast markets. Cue the ASUS XG-U2008, an unmanaged 10G networking switch available for only $249.99.

Tagged: wifi, onhub, mesh, google wifi, google, 802.11ac
Building on the company’s OnHub WiFi router program, the search giant will be offering up its own mesh WiFi network solution for home users later this year aptly named “Google WiFi.” Available in November for pre-order Google will offer single and triple packs of its puck-shaped smartphone controlled WiFi nodes.
Google WiFi is a new product that takes advantage of an old technology called mesh networking. While most home users rely on a single powerful access point to distribute the wireless signal throughout the home, mesh networks place nodes around the home in such a way that the WiFi networks overlap. Devices can connect to any node and transition between nodes automatically. The nodes communicate with each other wirelessly and connect end devices to the router and Internet by taking the best path (least number of hops and/or highest signal strengths). This model does have some disadvantages that are shared with WiFi repeater solutions in that as much as 50% (or worse!) of the bandwidth can be lost at each hop as the devices use wireless for both communicating with end devices and the backbone to the router. The advantage though is that you need only find a power outlet to set up the mesh node and there is no need to run Ethernet or deal with Powerline or MoCA setups.
Fortunately, it looks as though Google has mitigated the disadvantage by including two radios. The circular Google WiFi nodes (which measure 4.17” diagonally and 2.7” tall) pack a dual band 802.11ac WiFi chip that can operate at both 2.4 GHz and 5 GHz. Using the 5 GHz network for in room end devices (PCs, smartphones, game consoles, Rokus, et al) and the 2.4 GHz network to communicate with each other will help to eliminate a major bottleneck. There will likely still be some bandwidth lost, especially over multiple hops, due to interference, but it should be much less than 50% bandwidth loss.
Each Google WiFi node features two Gigabit Ethernet ports that can be setup as LAN or WAN ports, Bluetooth, and an 802.11ac 2x2 WiFi radio with beamforming support. The nodes are powered by an unspecified quad core processor, 512MB DDR3L memory, and 4GB of eMMC flash storage. The nodes apparently draw as much as 15 watts.
Of course, being Google, the Google WiFi can be controlled using an Android or iOS app that allows the administrator to pause WiFi on a per-device basis (e.g. set time limits for children), monitor device bandwidth usage and prioritize traffic, and automatically apply firmware updates to mitigate security risks. Additionally, Google WiFi automatically configures each node to use the best channel and band to get the best performance that supports all devices.
The nodes currently come only in white and are constructed of plastic. There are blue LEDs around the middle of the puck shaped device. Google WiFi will be available for pre-order in November. A single node will cost $129 while a three pack will cost $299. Google is not first to the wireless mesh party but it looks like it will be competitively priced (the three pack is $200 cheaper than eero, for example).
This looks like it might be a simple to setup solution if you or your family are currently running a single access point that can’t quite cover the entire home. I don’t really see this as a product for enthusiasts, but it might be worth recommending to people that just want WiFi that works with little setup. I will have to wait for reviews to say for sure though.

Tagged: qualcomm, iPhone 7 Plus, iPhone 7, iphone, Intel, apple
Not every iPhone is created equal. Dual-sourcing parts is fairly common, especially in the mobile space. Samsung, for instance, is known to have separate models of the same phone, with some using its own parts, and others using third-party components. Apple has even designed separate versions of the same SoC in the past, to fabricate them at different locations and on different process technologies.
This case is more simple than that, though. Depending on the specific iPhone 7 that you get, which mostly varies by region and carrier, but also apparently between Plus and regular, you will either get a Qualcomm Snapdragon X12 modem, or you will get an Intel XMM 7360 modem. The ratio between these two parts, all markets considered, doesn't seem to have been announced yet, but old rumors claim about 70:30, Qualcomm-to-Intel. Still, Apple is a pretty big customer, so I'm hoping that both Intel and Qualcomm are moving enough to (Update: Sigh... input fail... original article cut off here. The rest of the sentence, after this update, was added a couple hours later.) be worthwhile for both parties.

Ars Technica took router modding to a new level this year; why just flash your router with OpenWRT when you can make one from a mini PC? The original was a dual gigabit NIC mini-PC with a 1037u Ivy Bridge Celeron from Alibaba, Homebrew 2.0 is sourced from Amazon, has four Intel gigabit LAN ports and runs on a J1900 Bay Trail Celeron. You simply install an inexpensive SSD is installed in the mini-PC, set up OpenWRT and configure your network settings. In this latest update Ars compares their homebrew routers to several retail routers to see how they fall in terms of performance. Check it out to see how they fare and possibly to learn a bit about network benchmarks.
"Famously around the Ars forums, this problem soon evolved into our homebrew router initiative. In January, I showed my math as a DIY-Linux router outpaced popular off-the-shelf options like the Netgear Nighthawk X6 and the Linksys N600 EA-2750. And in August, I shared the steps necessary to build one of your own."

Tagged: Rivet Networks, NiC, networking, Killer Networking, Killer E2500, Ethernet, controller
Rivet Networks have announced the new Killer E2500 Gigabit Ethernet controller, and they are partnering with MSI and GIGABYTE to bring the new controller to consumer gaming motherboards.
“The Killer E2500 delivers powerful networking technology to gamers and performance users, including significant new enhancements to its Advanced Stream Detect 2.0 Technology and the all new Killer Control Center. In addition to detecting and optimally prioritizing your games, video, and voice applications with Advanced Stream Detect 2.0 Technology, the Killer E2500 also detects and manages 500+ of the top global websites.”
The networking performance is said to be improved considerably with the new controller and software, with "Lag and Latency Reduction Technology":
“Through its patented technology, Killer is able to get network packets to your applications and web browsers up to 25% faster than the competition during single application usage, and potentially by more than 10x faster when multitasking.”
As I quickly realized when reviewing the Killer Wireless-AC 1535 last year, the software is just as important as the hardware with a Killer adapter. For the new E2500, the Killer Control Center has been re-designed, to provide “users full control of all aspects of their system’s networking performance”.
Rivet Networks describes the functionality of this Killer Control Center software, which allows users to control:
- The priority of each application and popular website
- The bandwidth used by each application and popular website
- The Killer interface that each application is going over
- The total bandwidth being used by system
I found that enabling the Killer Software bandwidth management to significantly affect latency when gaming (which you can see here, again revisiting the AC 1535 review), and Rivet Networks is confident that this new system will offer even better performance. We’ll know exactly how this new controller and software performs once we have one of the new motherboards featuring this E2500 controller onboard.
Actiontec MoCA WCB6200Q and ECB6200 Review
Occasionally we’ll get some gear rolling through the PCPer offices that are a bit off the beaten path. The pair of devices on tap today are something you may not come across often, and could very well be something you may not have even heard of. They are niche products serving a niche need, and that niche is “MoCA.” Today we’re looking at the Actiontec WCB6200Q 802.11ac MoCA 2.0 Wireless Network Extender and its partner in crime the Actiontec ECB6200 Bonded MoCA 2.0 Network Adapter.

Tagged: bluetooth 5, bluetooth
The fourth version of Bluetooth was released almost six years ago now. Its main focus was lower power, which was very important at the time. Bluetooth and WiFi were major energy sinks for mobile devices, and smartphones were taking off. This was also during the first wave of tablets.
The Bluetooth special interest group has now announced Bluetooth 5. The headlining features are
double range and quadruple speed for low-powered Bluetooth connections. (Update, June 13th @ 1:15pm: Bluetooth's PR agency contacted me, said the source's numbers were backwards, and asked me to update to the correct ones. It's double speed and quadruple range for low-powered Bluetooth connections.) This is obviously useful for a data communication protocol, although it is difficult to tell whether low bandwidth was an issue for many devices. It is not exactly something that hardware vendors would publicly complain about.
They also intend to allow certain services to operate without pairing. The open letter says that it is intended to be used with “beacons” and “location-based services” but fails to elaborate. Instead, it points to their Discover Blue: London event on June 16th, so I expect that will be expanded upon there. Part of me is concerned that connectionless could turn into “operates without user control,” but, ultimately, the device is responsible for what it executes. There shouldn't be a way that a protocol, without the OS being involved, could force an interaction -- at least not without a backlash against the OS for permitting it.
Again, we'll find out more in about a week, on June 16th.
