Mimosa Networks: Outdoor Multi-User MIMO

Mimosa Networks, a pioneer in gigabit wireless technology, has announced a new suite of outdoor 802.11ac 4×4 access points and client devices, to create “the world’s highest capacity low-cost outdoor solution and the first with MU-MIMO”. It’s targeting Wireless ISPs and enterprises, but their products won’t be available until Summer/Fall 2015.

Currently most 802.11ac access points use Single User MIMO where every transmission is sent to a single destination only. Other users have to wait their turn. Multi-User MIMO lets multiple clients use a single channel. MU-MIMO applies an extended version of space-division multiple access (SDMA) to allow multiple transmitters to send separate signals and multiple receivers to receive separate signals simultaneously in the same band.

With advanced RF isolation and satellite timing services (GPS and GLONASS), Mimosa collocates multiple radios using the same channel on a single tower while the entire network synchronizes to avoid self-interference.

Additionally, rather than relying on a traditional controller, the access platform takes advantage of Mimosa Cloud Services to seamlessly manage subscriber capacities and network-wide spectrum and interference mitigation.

“The next great advancement in the wireless industry will come from progress in spectrum re-use technology. To that extent, MU-MIMO is a powerful technology that enables simultaneous downlink transmission to multiple clients, fixed or mobile, drastically increasing network speed and capacity as well as spectrum efficiency,” said Jaime Fink, CPO of Mimosa. “Our products deliver immense capacity in an incredibly low power and lightweight package. This, coupled with MU-MIMO and innovative collocation techniques, allows our products to thrive in any environment or deployment scenario and in areas with extreme spectrum congestion.”

The A5 access points are available in 3 different options: A5-90 (90º Sector), High Gain A5-360 (360º Omni with 18 dBi gain) and Low Gain A5-360 (360º Omni with 14 dBi gain). The C5 Client device is small dish, available in 20 dBi gain. The B5c Backhaul leverages 802.11ac, 4×4:4 MIMO and is said to be capable of 1 Gbps throughput.

All four of the products will debut in wireless ISP networks in Summer/Fall 2015 and are currently available for pre-order on the Mimosa website. List Prices are: $1099 for A5-90, $999 for A5 360 18 dBi, $949 for A5 360 14 dBi, $99 for C5.

Mimosa Networks says the new FCC 5 GHz Rules Will Limit Broadband Delivery. New rules prohibit the use of the entire band for transmission, and instead require radios to avoid the edges of the band, severely limiting the amount of spectrum available for use (the FCC is trying to avoid interference with the 5.9 GHz band planned for transporation infrastructure and automobiles).

In addition, concerns about interference of Terminal Doppler Weather Radar (at 5600-5650 MHz) prompted the FCC to disallow the TDWR band. Attempting to balance the needs of all constituencies (pdf), the new FCC regulation adds 100 MHz of new outdoor spectrum (5150-5250 MHz), allowing 53 dBm EIRP for point-to-point links. At the same time, however, it disqualifies Part 15.247 and imposes the stringent emissions requirement of 15.407 ostensibly in order to avoid interference with radar.

Mimosa – along with WISPA and a number of other wireless equipment vendors – believes that the FCC’s current limits will hurt the usefulness of high gain point-to-point antennas. Mimosa wants FCC to open 10.0-10.5 GHz band for backhaul.

Multi-User MIMO promises to handle large crowds better then Wave 1 802.11ac products since the different users can use different streams at the same time. Public Hotspots serving large crowds will benefit with MU-MIMO but enterprise and carrier-grade gear could be a year away, say industry observers.

The FCC has increased Wi-Fi power in the lower 5 GHz band at 5.15-5.25 GHz, making Comcast and mobile phone operators happy since they can make use of 802.11ac networks, both indoors and out, even utilizing all four channels for up to 1 Gbps wireless networking.

The FCC’s 5 GHz U-NII Report & Order allowed higher power in the 5.150 – 5.250 GHz band.

These FCC U-NII technical modifications are separate from another proposal currently under study by the FCC and NTIA that would add another 195 MHz of spectrum under U-NII rules in two new bands, U-NII 2B (5.350 – 5.470 GHz) and U-NII 4 (5.850 – 5.925 GHz).

Commercial entities, including cable operators, cellular operators, and independent companies seem destined to blanket every dense urban area in the country with high-power 5 GHz service – “free” if you’re already a subscriber on their subscription network
.

WifiForward released a new economic study (pdf) that finds unlicensed spectrum generated $222 billion in value to the U.S. economy in 2013 and contributed $6.7 billion to U.S. GDP. The new study provides three general conclusions about the impact of unlicensed spectrum, detailing the ways in which it makes wireline broadband and cellular networks more effective, serves as a platform for innovative services and new technologies, and expands consumer choice.

Google Fiber Going Wireless?

Google has applied to the FCC for permission to begin wireless spectrum tests in the San Francisco area. According to Reuters, the company’s looking into a rarely-used millimeter wave frequency that is capable of transmitting large amounts of data, but only if the receiving equipment is in the line-of-sight.

Google reportedly may offer a fast wireless service in markets where it offers Google Fiber Internet and TV service. By beaming Internet services directly into homes, Google would open a new path now dominated by Comcast, Verizon and AT&T.

The Google wireless test, beginning Nov. 13, will apparently include three sites in the San Francisco Bay Area, including one in San Mateo county and two locations a half-mile apart which appear to be on Google’s Mountain View, California campus. It will use the 5.8 GHz frequency, the 24.2 GHz frequency and the millimeter wave bands of 71-76 GHz and 81-86 GHz, according to the application.

The FCC’s meeting on Friday discussed the use of wireless spectrum above 24 GHz for mobile services, including ways the agency can facilitate the development and deployment of technology. Their Notice on Inquiry looks at utilizing frequencies above 24 GHz for mobile use and “5G” applications. The FCC also adopted a Report and Order to facilite and clarify the use of public infrastructure for wireless transmitters.

Google bought Alpental Technologies in June, a stealthy Seattle startup led by ex-Clearwire researchers. Apparently Alpental will utilize 60 GHz 802.11ad and mesh networking.

The FCC loosened some rules governing the 60GHz band last year, saying that it could be used to provide wireless connections of up to a mile at speeds up to seven gigabits per second.

A wireless broadband network is cheaper than fiber. Rather than digging up roads and laying cables to each individual home, transmitters on nearby buildings could enable Google to bring Gigabit internet to more places in less time. Craig Barratt, the former Atheros Communications CEO, is now head of the Google Access and Energy division. He signed off as the authorized person submitting Google’s FCC application.

New iPads Leaked

Apple appears to have accidentally spilled the beans about the iPad Air 2 and iPad mini 3, notes Engadget, which are expected to be announced tomorrow.

Cupertino’s tablets will apparently be getting Touch ID and burst shooting mode, which will be coming to the iPad Air 2, but not the mini 3, according to the document released by Mac 9to5. Besides the tweaked designs and Touch ID sensors, a gold color option, and a stronger A8X processor, improved camera optics, and new software can be expected at least on the new Air.

C/Net, ,9 to 5 Mac, Engadget and Twit.tv will have live coverage from Apple starting tomorrow at 10 am.

Google Announces Nexus 6, Nexus 9 and Nexus Player

Google Android 5.0 is ready to go. The next version of Android is called Lollipop (Android 5.0), and today Google announced the first products that will ship with the new software.

The Google Nexus 6, Nexus 9, and Nexus Player will all run Android 5.0 Lollipop when they hit the streets in November. An Android 5.0 SDK launches on October 17th. And in the coming weeks Google will roll out Android 5.0 software updates to some recent Nexus and Google Play Edition phones and tablets.

  • The Nexus 6 is the biggest Nexus phone that Google has released, with a 6-inch display — bigger than both the iPhone 6 Plus and Galaxy Note 4. Like the Note 4, Google’s Nexus 6 also uses a Quad HD display and has a Snapdragon 805 processor, a 13-megapixel rear camera, a 2-megapixel front camera, a 3220 mAh battery, and two front-facing speakers.

    The Nexus 6 will be sold unlocked for $649, making it far more expensive than any other Nexus model to date. It comes running Android 5.0 Lollipop and can include either 32 or 64GB of internal storage in either blue or white. The Nexus 6 will be available to preorder on October 29th and available in stores beginning in November. You’ll also be able to buy it on monthly contract. The unlocked model will work on all four major US carriers.

  • The Nexus 9 features an 8.9-inch QVGA (2048×1536) display with a ratio of 4:3 as opposed to 16:9, and Nvidia’s Tegra K1 chipset. The device also features 2GB of RAM and, on average, around 9 hours of battery life. HTC has HTC’s BoomSound speaker technology.

    Nexus 9 will be available to preorder beginning October 17th for $399 and comes in three configurations: 16GB for $399, 32GB for $479, and an LTE-enabled 32GB model for $599. Sadly, you can’t expand that storage through microSD. It’s available in either black or white. A keyboard attachment can “magnetically attach. Nexus 9 will be available for pre-order in the Google Play store beginning October 17, and will show up in stores on November 3.

  • The Nexus Player is Google’s first Android TV device. The set-top streaming box is made by Google and Asus and is Google’s latest in a very long line of attempts to take over your TV. Announced back in June, Android TV has a good-looking interface that allows you to stream music, movies, and TV shows. You can also play Android games on it, and it can mimic the Chromecast’s features too. Inside there’s a 1.8GHz Intel Atom CPU and a PowerVR GPU, with 1GB of RAM and 8GB of storage. It’ll be available for pre-order on Oct. 17 and in stores starting November 3, priced $99.
  • The Nexus 5 is still available, same as usual but with the same price (starting at $350). It will likely be upgraded to Android 5.0 in the next few weeks.

Lollipop will be made available to the Nexus 5, 7, 10, and Google Play edition devices in the coming weeks. Motorola also said it will update many of its devices to Android 5.0 Lollipop, including the Moto X (1st Gen and 2nd Gen), Moto G, Moto E, as well as the Droid Ultra, Droid Maxx, and Droid Mini. Phone Arena has an in-depth specs comparison between the Nexus 6 and iPhone 6 Plus.

Lollipop has a consistent design across devices—an approach they call Material Design. Now content responds to your touch and voice, in more intuitive ways, and transitions between tasks are more fluidly. Lollipop also lets you adjust your settings so that only certain people and notifications can get through.

According to the latest figures from App Annie’s quarterly market reports, Google Play downloads now exceed Apple’s App Store by 60 percent, but iOS apps still make more money

Qualcomm Buys Silicon Radio, Huawei Buys Neul

Qualcomm is buying British Bluetooth chipset specialist CSR for $US 2.49 billion. Qualcomm said the deal will give it access to CSR’s products, channels and customers in the connect car and Internet of Things markets.

CSR, which is short for Cambridge Silicon Radio, is a pioneer in Bluetooth and its silicon is in portable audio speakers and Apple-owned Beats headphones. CSR rejected a takeover bid from Microchip Technology in August. CSR’s deal with Qualcomm is expected to close by the end of the summer of 2015.

Classic Bluetooth and Bluetooth Low Energy chips are quickly getting commoditized, but CSR is a pioneer of the short-range wireless technology and is now pushing CSRmesh, a ZigBee-like mesh technology built on Bluetooth. CSR sees CSRmesh as a linchpin for its foray into the IoT market, reports EE Times.

In July Qualcomm bought WiGig chipmaker Wilocity, a move designed to enable Qualcomm to easily integrate the 60 GHz Wi-Fi technology into its mobile platforms to enable wireless streaming of 4K video for mobile and settop devices. Qualcomm also developed AllJoyn, an open-source platform that allows devices to share information with other nearby devices.

White space technology in the UK was among the first of its kind in Europe. Their pilot projects utilize unused terrestrial TV broadcasting channels (from 470 MHz to 790 MHz).

The Weightless specification, an open wireless standard, was originally developed for television White Spaces (unused channels in the television band). The Weightless-W spec works in TV White Spaces, but TV channels are not available everywhere and sometimes the full feature set is unnecessary.

For this reason the Weightless SIG is developing a variant called Weightless-N. The two variants of the Standard, Weightless-W (for White Spaces) and Weightless-N (for the unlicensed ISM band) will coexist offering benefits to developers and users according to their specific use cases. Weightless-N will typically be deployed in unlicensed spectrum in the region 800-900MHz such as the 868MHz band in Europe and the 900MHz ISM band in the US. It is also designed to work in licensed spectrum around these frequencies.

The Weightless connectivity platform was developed by Neul (the Gaelic world for ‘cloud’). It was first targeted at the TV white spaces (TVWS) spectrum, but extending the spec to 900MHz and other bands (including licensed) requires some modificiations. The unlicensed bands are narrower than those found in TVWS, and that required some changes to the air interface which are found in Weightless-N. Neul itself has released the first commercial chipset to support the would-be standard, called Iceni.

The Narrowband IoT is designed to work at sub-gigahertz frequencies as part of future 3GPP cellular standards for connecting low data rate devices that have exceptionally long battery life. There is great spectrum efficiency using just 200kHz. It will work at the 450, 850 and 900MHz frequencies used by GSM and at the lower frequencies that some LTE uses.

The CEO of the Weightless special interest group, Professor William Webb, offered up some comment on the launch of Weightless-N, saying “Enabling the vision of 50 billion connected devices requires chipset costs below $2, battery life of 10 years or more and a range of 5km or more to ensure ubiquitous coverage from a low cost network.

Chinese giant Huawei bought Neul for $125m last month. Huawei will reportedly build a “center of excellence” around Neul in the UK.

Weightless will likely compete with IEEE white space standards such as 802.11af and IEEE 802.22 for wireless white space networks.

The 802.11af standard, based on Wi-Fi like protocols, is designed for ranges up to 5 km, while the 802.22 standard is based on WiMax chipsets and incorporates polling, for wireless regional area networks with ranges up to 100 km.
