While many short range M2N solutions are available, such as Wi-Fi, Bluetooth, ZigBee, Z-Wave and others, they cannot provide long-range coverage.
The IEEE standards group has developed a couple of White Space standards that promise better range. Those include the 802.11af standard, based on Wi-Fi like protocols, for ranges up to 5 km. Additionally, the 802.22 standard, based on WiMax chipsets which incorporate polling, are designed for wireless regional area networks with ranges up to 100 km. But both of those standards appear to be targeting broadband connections.
The Weightless standards, by contrast, delivers a slower, narrow-band solution that connects to more devices and requires very little power. It may even be used on licensed cellular frequencies.
The Weightless standard aims to connect sensors that require long range connections and is targeting applications like vehicles and asset tracking, healthcare and metering.
While improved coverage can be supplied by cellular technology using GPRS, 3G and LTE, cellular costs are high, using more power and bandwidth than desirable. The Weightless SIG uses television white spaces and the lower unlicensed ISM band (800-900 MHz) for improved range using a slower but error-resistant data scheme.
Weightless uses a spreading algorithm to create a longer data sequence when the signal levels are weak. It reduces the data rate and shifts to a simpler modulation scheme to reduce the error rate or increase range. It enables coverage up to 5km (3 miles) to indoor terminals.
The Weightless SIG announced the development of the Weightless-W standard, which uses TV white spaces, last year. This year the the Weightless-N standard, using the unlicensed 800/900 MHz ISM band was announced. It uses Ultra Narrow Band (UNB) technology and operates in ISM band – 868MHz in Europe and 915MHz in the US, and may also use cellular frequencies around 800 MHz.
Professor William Webb, CEO of the Weightless SIG said, “We are delighted to welcome NWave Technologies Limited to the Weightless SIG. NWave is a leader in IoT over ISM spectrum and the company’s deep technical experience in LPWAN connectivity will make a significant contribution to the rapid development of Weightless-N. Bringing proven capability from an existing technology provider to the SIG and merging it with the expertise already established within the group will accelerate the development of Weightless-N as the leading global open standard for machine connectivity over licence exempt spectrum.”
The Qualcomm Atheros QCA9377 chip extends the performance benefits of MU | EFX to notebooks, TVs, cameras, and other consumer electronics, while Qualcomm’s single-stream 11ac + Bluetooth 4.1 combination chip is designed to provide the best possible performance with reduced power consumption.
Qualcomm says AVM will introduce a new FRITZ! Box router based on the Qualcomm IPQ and 4-stream 802.11ac with MU-MIMO products, targeting both retail and carrier segments. Qualcomm Atheros has enabled mobile customers using its 802.11ac products (QCA6174A and WCN3680B) to include Qualcomm MU | EFX in forthcoming smartphones and tablets.
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.”
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.
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.
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.
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.
AT&T Mobility, Sprint, T-Mobile US and UK operator EE support a new SIM card for Apple’s iPad Air 2 and iPad mini 3 that lets customers switch between carriers. With an unlocked phone or tablet you can change your service provider by changing the SIM card, but with Apple’s new SIM card, you won’t need to buy a second (or third) SIM card.
Apple’s SIM card enables customers to easily switch service to a different carrier. As GigaOM notes, it’s unclear how the provisioning process will work if customers want to switch between carriers. While Verizon Wireless will provide wireless service for Apple’s new tablet, it is not listed as a supporter of the new Apple SIM card, notes Fierce Wireless.
“The new Apple SIM is preinstalled on iPad Air 2 with Wi-Fi + Cellular models,” Apple explains. “The Apple SIM gives you the flexibility to choose from a variety of short-term plans from select carriers in the U.S. and UK right on your iPad. So whenever you need it, you can choose the plan that works best for you–with no long-term commitments. And when you travel, you may also be able to choose a data plan from a local carrier for the duration of your trip.”
The Subscriber Identity Module stores your International Mobile Subscriber Identity number (IMSI), which is a unique serial number (ICCID), along with security and network data, your PIN, and a personal unblocking code. The SIM allows you to connect to the network and identifies you.
The International Mobile Station Equipment Identity number (IMEI), on the other hand, is on the phone itself and identifies the device. It’s like a VIN number on a vehicle and can be used for stopping a stolen phone from accessing the network by calling a network provider to “blacklist” the phone using its IMEI number.
Clearly, if Apple hopes to move many iPad minis in the Chinese market, they will need Band 41 support (and perhaps an A8X chip). Apple launched its latest iPhone 6 in China today. According to China Mobile, subscriptions reached 799.13 million, compared to 755.19 million a year ago. That included 244.5 million users of 3G services, and 40.95 million largely on their new TD-LTE network using band 41.
Verizon and AT&T both told the FCC that compliance with the lower “A Block”, which smaller carriers use in the United States, would not be practical or cost/effectice. Guess that problem was solved when Dish lowered their potential power on the single channel “E Block”. Perhaps adding FirstNet compliance (on Band 14) may also be comparitively easy. Of course they’d have to deal with Motorola Solutions, the part of Motorola not sold to Lenovo.
Motorola Mobility consists of the Mobile Devices business which produces smartphones and the Home business which produces set-top boxes and cable modems. Google sold most of Motorola Mobility to Lenovo for $2.91 billion.
Aerohive’s HiveManager Network Management System has the ability to manage devices from the cloud, so a central administrator can control wireless access remotely, regardless of where the routers are located. Corporate networks can then easily deploy secure, wireless networks and reduce complexity and time-to-operation of Wi-Fi deployments, says Aerohive.
IDC predicts that the number of connected “things” will grow from 11.4 billion in 2014 to 28.1 billion in 2020. As a result, branch locations in industries ranging from hospitality to banking must be equipped to meet connectivity needs while ensuring secure, compliant access to corporate resources, says Aerohive.
