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.

Tech Leaders: NSA Damages Digital Economy

Sen. Ron Wyden (D-Ore.) convened a roundtable on “The Impact of Mass Surveillance on the Digital Economy,” at Palo Alto High School — the same gym where the Senator held a school record of leading scorer in basketball.

Wyden, now better known as chairman of the Senate Finance Committee, was flanked by executives and lawyers from some of U.S. tech’s biggest companies: Microsoft, Google, Facebook and Dropbox.

The hour-long session shifted from talk about the digital economy to the risks posed by government surveillance programs to human-to-human communications.

Wyden cited a study from Forrester Research that found that surveillance concerns could cost U.S. companies a quarter of their foreign revenue by 2016.

According to Microsoft general counsel Brad Smith:

“The fundamental issue is pretty straightforward. It’s all about trust. And it is personal to people. Just as people would not put their money in a bank they don’t trust, they will be reluctant to store their personal information in a data center or on a phone that they don’t trust. These issues have undermined people’s trust in American technology, and that’s a shame.”

“If you’re a consumer or a company, you own your email, your text messages, your photos and all the content that you create,” he said. “Even when you put your content in our data centers or on devices that we make, you still own it and you are entitled to the legal protection under our Constitution and our laws. We will not rebuild trust until our government recognizes that fundamental principle.”

Congress has been considering reforms to U.S. digital communication laws, particularly the USA FREEDOM Act. But those efforts have been slow going, reports the Washington Post. With only a bare majority of Americans opposed to U.S. government anti-terrorism surveillance, the event was likely a preview of how the issue will be framed when Congress returns to session: as a personal affront to American citizens, to U.S.-based technology entrepreneurs and to the global community.

“The simplest outcome is we’re going to end up breaking the Internet,” said Google’s Schmidt. Foreign governments, he said, are “eventually going to say, we want our own Internet in our country because we want it to work our way, and we don’t want the NSA and these other people in it.”

Google Executive Chairman Eric Schmidt said the spying scandal will continue to impact Google and other tech companies.

The impact is “severe and is getting worse,” Schmidt said. “We’re going to wind up breaking the Internet.”

FCC Prepares for AWS-3 and 600 MHz Spectrum Auctions

The FCC claims there are no limitations on bidding eligibility for the upcoming AWS-3 auction, scheduled to start on Nov. 13th. The AWS auction will be the most significant airwaves auction since the 700 MHz auction in 2008. Verizon, AT&T and T-Mobile, as well as Dish Network are on the list of bidders released by the FCC. A total of 80 entities submitted initial applications.

There is currently 50 megahertz of spectrum set to be auctioned off for commercial services in those proceedings, which have garnered interest from most commercial operators. The spectrum license will include three 5×5 megahertz options, leaving just a single 10×10 megahertz license covering the country.

The FCC adopted rules to allocate another 15 MHz and license the 1695-1710 MHz band for uplink/mobile operations on an unpaired shared basis with incumbent Federal meteorological-satellite (MetSat) data users.

RCR Wireless News spoke with CCA President and CEO Steve Berry at the Competitive Carrier event in Las Vegas to get his view on how the FCC was handling the auction proceedings.

In July, the FCC and the NTIA issued a 43-page public notice outlining coordination procedures for the AWS-3 bands.

Meanwhile, FCC continues to make progress on crafting rules for the planned 600 MHz incentive auction (pdf), this week rolling out an information package (pdf) targeted at television broadcasters, RCR Wireless News.

The auction is scheduled for mid-year 2015, but several parties, including the National Association of Broadcasters, have challenged the auction in court, which could potentially push back that timetable.

FCC Chairman Tom Wheeler has said the greatest challenge for the planned 600 MHz incentive auction process will be in convincing broadcasters to participate in the “reverse” auction process, noting at a recent speech that the opportunity was a once-in-a-lifetime chance to garner financial compensation for underutilized airwaves.

NAB’s members say they will lose coverage area during the auction’s repacking and reassignment process, or be forced to participate in the auction (and relinquish broadcast spectrum rights),” the NAB lawsuit stated.

Broadcasting & Cable calculated $38 billion would wind up in TV broadcasters pockets after the FCC funded the FirstNet emergency responder network and paid the auction costs as well as the TV stations moving expenses as they relocated to new frequencies.

The auction is estimated to generate as much as $45 billion. Some $19.5 billion was raised in the 2008 auction of 700 MHz spectrum. But the 2008 auction was for nearly half the spectrum and before the smartphone’s huge impact on bandwidth.

Wheeler took to the stage at the recent Competitive Carriers Association and CTIA trade shows to encourage mobile operators to participate in the 600 MHz proceedings, which are currently scheduled to begin in mid-2015.

If everything does goes according to the FCC’s plans, about 100 MHz of airwaves would be freed up for commercial mobile broadband services like LTE. The remaining 26 MHz would become guard bands between broadcasters and uplink and downlink transmissions, but that spectrum would also be made available for white space broadband uses.

FCC: Better Rural Broadband & 5G Spectrum

FCC Chairman Tom Wheeler wants to see to the program that provides subsidies for Internet service in public schools and libraries known as E-Rate address broadband access by schools and libraries in rural areas, reports Roll Call.

In prepared remarks for an education technology event in Washington on Monday, Wheeler said that “75 percent of rural public schools today are unable to achieve the high-speed connectivity goals we have set.” He pointed to lack of access to fiber networks and the cost of paying for it when it’s available.

Wheeler says the FCC has set a clear target of $1 billion per year for Wi-Fi based internal networks for schools and libraries. “As a result, we will begin to see results in the next funding year, with expanded support for Wi-Fi to tens of millions of students and thousands of libraries”.

Wheeler’s speech comes after the FCC made changes to the E-Rate program this summer. Wheeler’s earlier plan to shake up the program was only partly successful — his FCC colleagues agreed to make more money available for Wi-Fi, as Wheeler proposed in June, but only if the money isn’t needed for basic Internet connections.

In other news, in announcing its agenda for its Oct. 17 open meeting, the FCC said it will vote on a Notice of Inquiry to “explore innovative developments in the use of spectrum above 24 GHz for mobile wireless services, and how the Commission can facilitate the development and deployment of those technologies.”

In a blog post, FCC Chairman Tom Wheeler wrote that the inquiry is aimed at broadening the FCC’s “understanding of the state of the art in technological developments that will enable the use of millimeter wave spectrum above 24 GHz for mobile wireless services.”

“Historically, mobile wireless services have been targeted at bands below 3 GHz due to technological and practical limitations. However, there have been significant developments in antenna and processing technologies that may allow the use of higher frequencies – in this case those above 24 GHz – for mobile applications”, wrote the Chairman.

5G or 5th generation wireless systems is expected to be the next major phase of mobile telecommunications standards and use frequencies above 5-6 GHz (where more spectrum is available. 5G does not describe any particular specification in any official document published by any telecommunication standardization body, and is expected to deliver over 10 Gbps, compared to 1 Gbps in 4G. It is expected to be first utilized for backhaul to cell sites.

Currently, Ubiquiti’s AirFiber has set the standard in 24 GHz at $3K for 700 Mbps while SAF, Trango, and others have announced similar products at $5000 or less.

Regarding “net neutrality”, FCC chairman Tom Wheeler says financial arrangements between broadband providers and content sites might be OK so long as the agreement is “commercially reasonable” and companies disclose publicly how they prioritize Internet traffic.

Not everyone agrees. Netflix and much of the public accuses the FCC of handing the Internet over to the highest bidders. There is no deadline for the FCC to pass a new rule, and deliberations at the agency could continue into next year.

Proponents of government-owned broadband networks claim they introduce competition into the market, while critics say they are an inappropriate use of tax dollars and an example of government improperly competing with the private sector.

Australia’s Telstra Fires Up National WiFi Network

Australia’s largest telecommunications company, Telstra, will install two million public hotspots that will be available for free to Telstra subscribers as part of a plan to blanket public spaces with internet access.

Trials of the $100m project will begin by November, reports The Guardian, and will allow Telstra customers who agree to share their bandwidth to get free access to any hotspot. The data they use will be deducted from their home allowance.

Non-Telstra customers, and those who don’t share their home connection, will be able to connect for an as yet undisclosed fee.

Many of the hotspots will be repurposed public phones which are mostly located in busy areas.

The trial will include busy spots such as Bondi Beach in Sydney, Bourke Street Mall in Melbourne and Rundle Mall in Adelaide. Popular holiday spots and parts of Perth, Brisbane, Hobart, Canberra and Darwin will also be included.

Some 1,000 hotspots should be operational by Christmas at sites that will include Telstra shops and exchange buildings.

Australia’s National Broadband Network (NBN) is a nation-wide, wholesale-only, open-access fiber data network delivering fixed line and wireless broadband connections that are sold to retail service providers, who then sell Internet access and other services to consumers.

The 2.3 GHz and 3.4 GHz radio spectrum will be used to provide LTE fixed wireless covering approximately 4 per cent of the population outside the fibre footprint. NBN Co has also contracted with Space Systems/Loral to build and launch two Ka band satellites in 2015 at a total cost of A$2 billion, for more rural areas.

The cost, estimated at A$37.4 billion, will be financed by a combination of a Federal Government investment of A$30.4 billion and private investment for the remainder. NBN Co intends to begin paying dividends back to the Federal Government in 2021, and to have fully repaid the Government’s contribution by 2034.

The concept is similar to those planned by Comcast and AT&T in North America. AT&T has built a network of free hotspots for customers at thousands of places—including train stations, as well as Starbucks and McDonald’s locations across the country. Comcast’s Xfinity wireless network turns customer’s cable modems into public Wi-Fi hotspots accessible with an Xfinity account login.

In June, Comcast said its Xfinity WiFi footprint had expanded to about 3 million hotspots nationwide, getting it closer toward a goal of expanding that footprint to 8 million hotspots by the end of 2014.

Hotspot 2.0 is a new set of protocols to enable cellular-like roaming. A variety of partnerships are developing nationwide and world-wide, including:

Infrastructure providers are also enabling small businesses and organizations to “roll their own” Hotspot 2.0 network:

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.
