Multi-In Multi-Out routers are a wonderful thing, not only are the routers far more tentacular than before, the technology also make our unwired lives better as Sebastian explained.  The only thing that could make it better is a bandwidth boost, which is what these researchers at MIT have been working on.  In an experiment involving laptop bearing Roombas they showed a increase of 330% in transfer speeds thanks to synchronized phases allowing multiple signals to be sent on the same frequency.  Pop on over to Slashdot to learn more about their research.


"Scientists at MIT claim to have created a new wireless technology that can triple Wi-Fi data speeds while also doubling the range of the signal. Dubbed MegaMIMO 2.0, the system will shortly enter commercialization and could ease the strain on our increasingly crowded wireless networks."

Qualcomm Announces X16 Modem Featuring Gigabit LTE

Subject: Mobile | February 12, 2016 - 04:26 PM |
Tagged: X16 modem, qualcomm, mu-mimo, modem, LTE, Gigabit LTE, FinFET, Carrier Aggregation, 14nm

Qualcomm’s new X16 LTE Modem is the industry's first Gigabit LTE chipset to be announced, achieving speeds of up to 1 Gbps using 4x Carrier Aggregation. The X16 succeeds the recently announced X12 modem, improving on the X12's 3x Carrier Aggregation and moving from LTE CAT 12 to CAT 16 on the downlink, while retaining CAT 13 on the uplink.


"In order to make a Gigabit Class LTE modem a reality, Qualcomm added a suite of enhancements – built on a foundation of commercially-proven Carrier Aggregation technology. The Snapdragon X16 LTE modem employs sophisticated digital signal processing to pack more bits per transmission with 256-QAM, receives data on four antennas through 4x4 MIMO, and supports for up to 4x Carrier Aggregation — all of which come together to achieve unprecedented download speeds."

Gigabit speeds are only possible if multiple data streams are connected to the device simultaneously, and with the new X16 modem such aggregation is performed using LTE-U and LAA.

What does all of this mean? Aggregation is a term you'll see a lot as we progress into the next generation of cellular data technology, and with the X16 Qualcomm is emphasizing carrier over link aggregation. Essentially Carrier Aggregation works by combining the carrier LTE data signal (licensed, high transmit power) with a shorter-range, shared spectrum (unlicensed, low transmit power) LTE signal. When the signals are combined at the device (i.e. your smartphone), significantly better throughput is possible with this larger (aggregated) data ‘pipe’.


Qualcomm lists the four main options for unlicensed LTE deployment as follows:

  • LTE-U: Based on 3GPP Rel. 12, LTE-U targets early mobile operators deployments in USA, Korea and India, with coexistence tests defined by LTE-U forum
  • LAA: Defined in 3GPP Rel. 13, LAA (Licensed Assisted Access) targets deployments in Europe, Japan, & beyond.
  • LWA: Defined in 3GPP Rel. 13, LWA (LTE - Wi-Fi link aggregation) targets deployments where the operators already has carrier Wi-Fi deployments.
  • MulteFire: Broadens the LTE ecosystem to new deployment opportunities by operating solely in unlicensed spectrum without a licensed anchor channel

The X16 is also Qualcomm’s first modem to be built on 14nm FinFet process, which Qualcomm says is highly scalable and will enable the company to evolve the modem product line “to address an even wider range of product, all the way down to power-efficient connectivity for IoT devices.”

Qualcomm has already begun sampling the X16, and expects the first commercial products in the second half of 2016.

CES 2016: TP-Link First To Launch 802.11ad Router

Subject: Networking | January 13, 2016 - 12:03 AM |
Tagged: wireless router, tp-link, mu-mimo, gigabit ethernet, CES 2016, 802.11ad, 802.11ac

Last week, TP-Link launched a new wireless router that is the first to support the 802.11ad "WiGig" standard alongside the usual fare of wireless AC, N, B, G, and A Wi-Fi networks. Sporting eight foldable external antennas, the TP-Link Talon AD7200 will be available within the next few months.

The Talon AD7200 features four Gigabit Ethernet ports, two USB 3.0 ports, eight antennas, and an all black casing with status LEDs lighting up the front panel. Two Qualcomm Atheros chipsets along with an unspecified dual core processor clocked at 1.4 GHz make up the internal hardware. One Atheros chipset is solely for the new 802.11ad radio while the other handles the remaining networks.

TP-Link Talon AD7200.jpg

On the wireless side of things, the router supports simultaneous operation of a 5 GHz 802.11ac, 2.4 GHz 802.11n, and a 60 GHz 802.11ad network. Throughput is rated at up to 1,733 Mbps on the 5 GHz band, 800 Mbps on the 2.4 GHz, and an impressive 4,600 Mbps on the 60 GHz band. The 802.11ad network support is the really interesting part of this router. While the 60 GHz band allows for super fast connections, it has a range of only a few meters and it needs a clear line of sight without any obstructions – the signal can't pass through a person or even a decorative plant for example. This standard was initially intended for the connected living room that would allow users to stream or copy high bit-rate media from a mobile device or computer to your television. In that respect, the 60 GHz band works well and offers up plenty of bandwidth for the job. 

The router allows hand-offs from 802.11ad to 802.11ac/n/b/a (eg. when you leave the room you can still stay connected to the network and internet, just on the slower but still fast enough for Internet access network) and supports beamforming and multi-user MIMO. It is using an allegedly user friendly firmware.

It is strange to see a router supporting the standard though when a direct Wi-Fi connection between the computer and TV should do fine. It does open up some interesting possibilities though. Right now, consumer devices supporting 10 Gigabit Ethernet are extremely rare and still not very affordable. With 1 Gigabit links being commonplace for a number of years now they have started to be surpassed by 802.11ac Wi-Fi in (theoretical) throughput (though the ol' hardwired connection still holds stability and latency benefits). There is a new standard NBASE-T aimed at bridging the gap between 1 GbE and 10 GbE for home users that hits 2.5 Gbps and 5 Gbps but that is still very much in its infancy. If you had an 802.11ad access point in every room, or at least the places you needed high bandwidth connections, it would be a definite improvement over a Gigabit Ethernet connection for large file transfers (think a backup to a NAS or offloading pictures and video from your laptop or phone to your desktop for editing). Of course, WiGig docks are also a thing, and offer a wireless alternative to a Thunderbolt docking station.

802.11ad is not revolutionary and it has it's limitations, but it is extremely fast. I'm interested to see the benchmarks and what sort of setup this router will enable. According to Ars Technica, Lenovo and Acer have WiGig laptops and WiGig docks coming out this year, and hopefully USB 3.0 WiGig cards will come out before the end of the year. I have a need for networking speed.

CES 2016: D-Link Shows Off New DIR-A91 Router and Extender Bundle

Subject: Networking | January 6, 2016 - 01:14 PM |
Tagged: wifi extender, mu-mimo, D-Link, 802.11ac

D-Link is using CES to show off several new bits of consumer networking gear including the upcoming DIR-A91 router and a bundled Wi-Fi extender. The Verge was able to get several photos of the networking gear which are available here. Exact specifications are not yet available (D-Link does not have product pages up yet, either), but according to The Verge the DIR-A91 and the DAP-1655 Wi-Fi booster will set you back $470 and will be available in the second half of the year.

D-Link DIR-A91 Router and Wi-Fi Booster.jpg

Looking at the photos, the DIR-A91 is a smaller version of top end AC3200 and AC3150 routers. It supports 802.11ac with beamforming and will eventually support MU-MIMO with a firmware update. It offers up five RJ45 ports (4 LAN, 1 WAN) and a single USB port. Both the Wi-Fi router and extender each have four external antennas.

The router further supports up to eight of the Wi-Fi extenders (though the bundle only comes with one, they will be sold individually as well)  which appear to connect via Ethernet and provide an additional access point. It is not clear if they are alternatively capable of acting as a repeater (connecting to the router over wireless and then offering a new access point).

The price ($470!) is rather steep in my opinion, but if the performance is there the router and extender bundle may be a better option than a single super-router (like the 8 antenna arachnid monsters from ASUS, D-Link, Linksys, et al) for some people if you can run Ethernet to your other floors or the other end of the house (although Powerline Ethernet may be an option it'd be a bottleneck).

Asus' Upcoming RT-AC5300 Router Is A Massive Tri-Band Router

Subject: Networking | November 17, 2015 - 12:56 PM |
Tagged: nitroQAM, mu-mimo, gigabit router, broadcom, asuswrt, asus, 802.11ac

Asus has officially launched the RT-AC5300, a massive replicator tri-band wireless router. The new router is fenced in by eight large antennas that allow the device to support 4 x 4 MU-MIMO wireless on two 5 GHz and one 2.4 GHz bands.


The menacing high-end wireless router supports the latest wired and wireless consumer networking technologies and runs the AsusWRT firmware. The RT-AC5300 is clad in black with red accents. The top of the router is mesh to facilitate cooling. In addition to the eight antennas, there are five gigabit Ethernet ports (up to two ports can be configured as WAN ports), a USB 3.0 port, one USB 2.0 port, and physical buttons for WPS, Wi-Fi, and LED on/off.

Powered by a Broadcom chipset, the router supports 802.11ac as well as older N/G/B Wi-Fi standards. Using NitroQAM technology, the two 5 GHz bands each support up to 2,167 Mbps speeds while the 2.4 GHz band tops out at 1,000 Mbps. This is a boost over the usual 1,734 Mbps for 5 GHz and 600 Mbps for 2.4 GHz wireless bandwidth numbers. Asus claims that the router can run all three bands simultaneously along with beamforming to improve the signal to devices by focusing the signal. Note that the combined advertised "5334 Mbps" of the router includes all three bands but a single device would max out at the 2,167 Mbps theoretical maximum of a single band. The router is capable of automatically figuring out and using the optimal band to communicate with each device based on its capabilities and signal strength.

When it comes to wired connections, the router has four 1 Gbps LAN ports. It also supports 802.3ad link aggregation which allows using two of the gigabit ports to create a single 2 Gbps link to supported devices like network attached storage (NAS) and workstations.

Asus is using ASUSWRT firmware along with AiRadar beamforming, AiProtect security, and a subscription to WTFast GPN which is a service aimed at gamers that reportedly delivers decreased pings and lower latency connections to game servers.

Pricing and availability have not been announced, but CNET is reporting an expected price of $400 USD.

To say that this router is overkill for most is an understatement, but it is packed with features and is ready to stream a Stargate SG-1 marathon to all your devices!

Synology, a company best known for its home and small office network attached storage (NAS) devices, is branching out with its first wireless router. The Synology Router RT1900ac is a high end 802.11ac Wi-Fi enabled router that is paired with some rather slick looking and useful software.

The RT1900ac supports the latest consumer grade networking tech including 802.11ac MU-MIMO (beam forming to up to six devices), 802.11n 256-QAM, and wired Gigabit Ethernet. The 5GHz band tops out at 1300 Mbps while the 2.4GHz “N” band tops out at 600 Mbps though note that a single device cannot use the combined “1900” Mbps bandwidth and even then inter-device links are limited to gigabit speeds or less.

Synology Router RT1900ac Wireless Router.jpg

The rear of the router hosts five Gigabit Ethernet ports (1 WAN, 4 LAN) and three physical antennas which means a max of 3x3 MIMO to wireless devices. The left side of the router hosts a WPS (wireless protected setup) button and a physical Wi-Fi on/off switch while the right side of the router features a single USB 3.0 port and a SD card reader. 

Internally, the router is powered by a dual core processor running at 1 GHz paired with 256 MB of DDR3 memory. Synology rates the router at a maximum of 70 connected devices with as many as 40 concurrently transmitting data.

The operating system is called the Synology Router Manager and it can be accessed via a web interface or a mobile app called DS Router for Android and iOS.

Users are able to access the router using a GUI interface that is reminiscent of other Synology software. It supports parental controls (website blocking, scheduling, ect), application layer quality of service (QoS) on a per-device level, traffic management and bandwidth monitoring (per device as well as total bandwidth used). Users are able to initially setup the router using a web interface or the mobile app to guide them through setup.

The USB port (and SDXC card slot) can be used to share files and stream media to other devices. They can also be used to share a printer over the network or enable a mobile hotspot using a cellular modem dongle.

Interestingly, users can add additional software to their router from Synology. Optional applications from Synology’s Package Center allow using the router as a VPN, torrent box, RADIUS authentication server, DNS server, file share, and media server. Being able to extend the functionality of the router is nice to see and should be popular with enthusiasts though it does raise some security concerns.

This new router will be on display at CES 2016 and will be available in the US early next year for $150.

I’m interested to see the reviews on this as it certainly looks nice and the software looks much better than most!

Subject: Mobile | September 30, 2015 - 02:33 PM |
Tagged: X12 Modem, SoC, snapdragon 820, qualcomm, phones, mu-mimo, mobile, LTE, cell phones

The upcoming Snapdragon 820 is shaping up to be a formidable SoC after the disappointing response to the previous flagship, the Snapdragon 810, which was in far fewer devices than expected for reasons still shrouded in mystery and speculation. One of the biggest aspects of the upcoming 820 is Qualcomm’s new X12 modem, which will provide the most advanced LTE connectivity seen to date when the SoC launches. The X12 features CAT 12 LTE downlink speeds for up to 600 Mbps, and CAT 13 on the uplink for up to 150 Mbps.

LTE connectivity isn’t the only new thing here, as we see from this slide there is also tri-band Wi-Fi supporting 2x2 MU-MIMO.


“This is the first publicly announced processor for use in mobile devices to support LTE Category 12 in the downlink and Category 13 in the uplink, providing up to 33 percent and 200 percent improvement over its predecessor’s download and upload speeds, respectively.”

The specifications for this new modem are densely packed:

  • Cat 12 (up to 600 Mbps) in the downlink
  • Cat 13 (up to 150 Mbps) in the uplink
  • Up to 4x4 MIMO on one downlink LTE carrier
  • 2x2 MU-MIMO (802.11ac)
  • Multi-gigabit 802.11ad
  • LTE-U and LTE+Wi-Fi Link Aggregation (LWA)
  • Next Gen HD Voice and Video calling over LTE and Wi-Fi
  • Call Continuity across Wi-Fi, LTE, 3G, and 2G
  • RF front end innovations
  • Advanced Closed Loop Antenna Tuner
  • Qualcomm RF360™ front end solution with CA
  • Wi-Fi/LTE antenna sharing

Rumored phones that could end up running the Snapdragon 820 with this X12 modem include the Samsung Galaxy S7 and around 30 other devices, though final word is of course pending on shipping hardware.
