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.

GM & Ford to Build Self-Driving Cars for Michigan Testbed

General Motors announced Sunday it plans to introduce Cadillac models in two years that incorporate hands-free driving and Wi-Fi-enabled vehicle-to-vehicle communications with similarly equipped vehicles, reports C/Net. GM brands, Chief Executive Mary Barra announced the initiative in a speech at the Intelligent Transport Systems World Congress in Detroit on Sunday.

In May, Google unveiled a two-seater prototype vehicle that uses built-in sensors and a software system to safely maneuver the vehicle rather than a steering wheel and accelerator and brake pedals.

Google has been leading the charge in developing self-driving technology over the past couple of years, but several automobile manufacturers have also gotten into various aspects of the autonomous driving game, including Audi, Mercedes Benz, Ford, Nissan, Delphi, Toyota, and Tesla.

GM’s “Super Cruise” semi-automated technology will automatically keep a vehicle in a specific, properly equipped freeway lane, making necessary steering and speed adjustments in bumper-to-bumper traffic or long highway trips. The feature, which was unveiled in 2012, is expected to debut in a high-end Cadillac in 2016 on a 2017 model, and will eventually trickle down to other GM brands. It would likely use the 5.9 GHz band for Dedicated Short-Range Communication (DSRC).

The Vehicle to Infrastructure (V2I) system would act as a natural complement to the active traffic management projects that are up and running in European countries like England, Germany, Greece and The Netherlands, according to Barra.

For example, the M4 and M5 Smart Motorways near Bristol, England now include things like variable speed limits, dynamic routing and lane markings, and improved traveler information systems.

GM is joining the University of Michigan and the state of Michigan to develop vehicle-to-infrastructure driving corridors on 120 miles of metro Detroit roadways. State officials said Ford is also part of the effort. If a driver in a V2V-equipped car brakes suddenly in heavy fog, for example, every other V2V-enabled car around it will know, MDOT notes.

When the new corridor goes on line, 9,000 V2V-equipped cars are expected to be on the road as part of the program.

The University of Michigan’s Mobility Transformation Center (MTC), a major public-private R&D initiative that aims to revolutionize the movement of people and goods in society the university announced Friday. Plans call for implementing a working system in Ann Arbor by 2021.

Vehicle-to-Vehicle Network Proposed for United States

The National Highway Traffic Safety Administration (NHTSA) is seeking input about a possible federal standard for vehicle-to-vehicle (V2V) communications, which would let cars automatically exchange information, such as whether they’re close to each other.

On Monday, the NHTSA published a research report and issued an advance notice of proposed rulemaking (ANPRM) in hopes of collecting a lot of feedback before issuing a full NPRM in 2016.

Transportation Secretary Anthony Foxx said the technology holds the potential to significantly reduce crashes, injuries and deaths on the nation’s streets and highways.

Vehicle-to-vehicle (V2V) communications utilizes a wireless network where automobiles send messages to each other. Traffic signals or other stationary devices are called V2I, or vehicle to infrastructure.

A transponder would continually transmit the vehicle’s position, heading, speed and other information 10 times per second in all directions. It has a range around 1000 feet or about 10 seconds at highway speeds.

Vehicle-to-vehicle communications uses dedicated short-range communications (DSRC), using the 5.9GHz band, which is close to the new, higher power 5 GHz WiFi band authorized by the FCC. Proposed FCC rules would increase power for the U-NII-3 band–5.725-5.850 MHz, but it is drawing heavy criticism from highway advocates and wireless ISPs. The highway administration is concerned about possible DSRC interference from more powerful outdoor WiFi in the adjacent 5 GHz band.

The Association of Global Automakers has expressed concerns about more power in the adjacent 5 GHz WiFi band.

The TIA believes that the FCC acted correctly to promote use of the 5 GHz band by unlicensed devices, including allowing operations up to 5850 MHz which is adjacent to the automakers’ DSRC / U-NII-4 spectrum (5850-5925 MHz)

V2V would be a mesh network, meaning every node (car, smart traffic signal, etc.) could send, capture and retransmit signals. Five to 10 hops on the network would gather traffic conditions a mile ahead. That’s enough time for even the most distracted driver to take his foot off the gas. On the first cars, V2V warnings might come to the driver as an alert, perhaps a red light that flashes in the instrument panel, or an amber then red alert for escalating problems.

The intelligent highway communications network (using the 5.9 GHz band) is not directly connected to a car’s infotainment system which uses Bluetooth, WiFi and 4G commercial networks for passenger entertainment.

Five years ago infotainment ranked 27th on a list of features most cars shopper wanted. Now it’s in the top five.

According to research firm Analysys Mason, 11.5 million connected cars will ship this year, growing to around 170 million in 2023. General Motors’ OnStar service currently has 6 million customers. Worldwide sales of HUD-equipped cars will increase from 1.2 million units in 2012 to 9.1 million in 2020.

Tour de France 2014

The 101st Tour de France (NY Times, Wikipedia and Twitter), began on Saturday July 5, 2014 and continues until July 27, 2014.

The 21-stage race began in Yorkshire, U.K., and stretches across Europe including Spain and Belgium. The race spans a total of 3,664 kilometers (or approximately 2277 miles).

Some 3.5 billion people watch some part of the 4,700 hours of television coverage. It’s the most-watched sports event in the world after the Olympics and the FIFA World Cup. Unlike the other two, the Tour de France does not stay put in a few stadiums.

Broadcasting live to more than 180 countries from 21 stages over the course of a month is one of the most difficult challenges in broadcasting. Almost 200 riders compete over huge distances, many of which snake up and down isolated mountain passes.

This year they have experimented with fitting small cameras to riders, even though the footage can only be accessed after the race. Virgin Media used Siklu’s tiny Gigabit 60GHz radio for backhauling WiFi hotspots in Leeds, England.

Orange, a French communications multinational supplied infrastructure for the event. Cycling fans can follow live each of the stages directly on their PCs via the Orange portal. There are lots of apps, of course, on the Google Play and Apple’s Appstore

Fans have been risking life and limb to snap a selfies at the 2014 Tour.

Comcast’s NBC is charging $4.99 a day for live coverage.

Every morning, 25 engineers start building a communications headquarters from scratch, based in four trucks that travel from town to town. One truck is for the press, the second for photographers, and the third for broadcasters. The fourth truck is the heart of the communications infrastructure for the world’s media. The Orange Event trucks connect fiber to the France Telecom network and via satellites.

The feed is sent to one of two identical trucks provided by Orange, which provides all the communications infrastructure for the Tour. It is piped into high-bandwidth fiber optic lines and sent back to France, from where it is beamed to 185 countries and broadcast live with a delay of less than a second. Networks can add their own commentary on top.

Orange in partnership with EuroMedia France (formerly SFP), manages the Tour’s TV broadcasting.

EuroMedia provides motorcycle cameras, helicopters and aircraft in order to ensure broadcast (especially in the mountains). Images from motorcycle cameras are transmitted via high-frequency links to helicopters flying at 600 meters altitude that then retransmit them to aircraft flying at 3000 meters.

The aircraft then broadcast the image to the town where the finish line is located, via 4 HF aerials mounted on a crane 50 meters up. Out of the 4 aerials, 2 are used exclusively to receive images, while the other 2 are used to coordinate helicopters and motorcycle cameras with the production team.

Coverage of the race inside the 1750 m long Croix-Rousse tunnel in Lyon was made possible thanks to the special receiver system installed inside the tunnel.

NBC has online coverage of the Tour de France. Live video is shown in the upper left, but one can toggle the video to full screen.

The text column on the right has frames showing the peloton and other rider groups and a curated, Twitter-like news feed. The graphic frame at the bottom has five optional modes.

Orange telecom customers can access exclusive content on their mobile phones and tablet. Orange launched LTE-A this month in select cities, utilizing carrier aggregation encompassing frequencies in the 800MHz and 2600MHz bands, which will provide downlink transmission speeds of up to 75Mbps (800MHz) and 150Mbps (2600MHz) respectively, to deliver a combined download rate of 225Mbps.

Orange is installing Ericsson RBS 6000 base stations in Paris, as well as in the south-west and north-east regions of France. Orange plans to deploy LTE-A in early 2015 in 14 of the most densely populated cities, and expand outward. Orange expects 4G roaming will be available across Orange’s European footprint by the end of 2014.

The announcement came on the back of the commercial launch of rival Bouygues Telecom’s LTE-A network in Lyon, Bordeaux, Grenoble, Vanves, Issy-les-Moulineaux, Malakoff and Rosny-sous-Bois in June. It aggregates frequencies in the 800MHz, 1800MHz and 2600MHz spectrum bands. Residential users can access the LTE-A network using the Bbox Nomad mobile hotspot (above).

France is forecast to hit 10 million LTE connections within five years, accounting for close to one in eight of the country’s total connections by 2017.

GoAntenna: 10 Mile Cell Communications – Without Towers

GoTenna has developed a 6-inch-long antenna that connects to iPhones and Android phones via Bluetooth low energy. The antenna then transmits the data to other GoTennas through proprietary protocols, at 151-154 MHz. You can send text messages up to 160 characters as well as share your location on offline maps.

The gadget is available for preorder at $150 for two devices, since it takes two devices to form a peer-to-peer network.

It uses the Multi-Use Radio Service (MURS), an unlicensed personal radio service in the 150 MHz band. The goTenna is dependent on FCC approval and is currently undergoing FCC testing. If it doesn’t pass, money would be refunded, says the company.

According to the company, you can send & receive messages for free:

  • Share locations on detailed, offline maps (also for free!)
  • Instantaneous transmission within range
  • Automatic message retry & delivery confirmation
  • Individual & group messaging
  • “Shout” broadcasts to anyone within range
  • Proximal friend map & location pinging
  • Emergency chat
  • End-to-end encryption (RSA-1024) & self-destructing messages
  • Compatible with iOS & Android devices

When cell towers and wifi aren’t available, goTenna makes the phone you have in your hand useful. CEO and co-founder Daniela Perdomo told GigaOM that GoTenna’s range is limited only by the horizon, or up to nine miles in open environments. In a heavily wooded area, the signal would travel a shorter distance, but still about four miles. A goTenna can only be paired to one phone at a time.

The part-95 radio services (FRS/GMRS/MURS) is available for unlicensed use in the United States. It is intended for short-range local voice or data communications.

The 150 MHz VHF band, used by the Multi-Use Radio Service (MURS), propagates better outdoors. The 450 MHz UHF band is used by the Family Radio Service (FRS) has a maximum output of 500 mW while the General Mobile Radio Service (GMRS uses the lower 7 channels of FRS, in the 462 MHz range, with a maximum of 5 watts ERP. It requires a valid GMRS license, but propagates better in buildings and urban areas.

In Portland this Saturday cargo biking was utilized in the Disaster Relief Trials. Cell phones were turned off. Cyclists used paper maps and pedal power to move supplies.

Riders were required to haul 100 pounds of cargo over a 30-mile, obstacle-strewn course. In the more family-friendly Replenish Class, riders will be required to carry one passenger on a 15-mile “post-disaster household supply run.”

The Portland Bureau of Emergency Management and Multnomah County Emergency Management agencies were on-site at the Oregon Museum of Science to track the riders via radio. Representatives from the FEMA Region 10 staffed checkpoints.

Maybe next year goTennas and smartphones will enable real-time tracking and messaging.
