Verizon Upgrades Michigan Service to 4G – Almost

Verizon Upgrades Michigan Service to 4G - Almost

I was going to let this press release from Verizon Wireless slide without comment until I got to the end and then I had to jump right out of my Bach Seat and crank out this post. Verizon Wireless (VZ) told MiTechNews they are investing $850,000 in Michigan to upgrade 450 antennas on all of its cell sites between the Saginaw Bay north to the Mackinaw Bridge and east of Interstate 75 to Lake Huron. The company reports the new antenna equipment has resulted in incremental network coverage gains of up to one mile, improving overall reliability for customers.

The project will be complete when the company can swap equipment on one last tower in Roscommon where a nest of osprey chicks has called home since March.

MichiganOur customers in eastern northern Michigan are able to use their devices in more places, especially in buildings,” explained David MacBeth, executive director–Network, Michigan/Indiana/Kentucky region, Verizon Wireless. “We’re constantly refining our network to ensure our customers have the best experience every time they pick up their wireless device.

The company’s ongoing network investment in Michigan now totals more than $1.6 billion to increase the coverage and capacity of its network and to add new services.

Despite what Mr. MacBeth claims, I’ve heard about an organization that moved to VZW from another wireless provider and VZW could not provide the 4G or any G service in the building. When the customer pushed on VZW to provide any G or basic voice service in their building, the sales rep. came back and said, “we won’t help you because we spent all of our money.”

Verizon Wireless logoApparently, that was the wrong answer, the organization reportedly moved 20 smartphones accounts from VZW back to the previous provider. But hey it is a good press release at least because VZW cares about baby birdies.

What do you think?

Are you satisfied with Verizon Wireless 4G service indoors?

D-Light-ful LED Broadband

D-Light-ful LED BroadbandTEDGlobal has an intriguing presentation by Harald Haas who is developing a new type of light bulb that can access the Internet using light instead of radio waves. According to TEDGlobal, the professor of engineering at Edinburgh University, has been designing modulation techniques that pack more data onto existing networks, but his latest work leaps beyond wires and radio waves to transmit data via an LED bulb. The new technology will turn LED lights on and off, so fast the change is imperceptible to the human eye to enables broadband data transmission without any noticeable change in room lighting.

The system, which he calls D-Light, and hopes to commercialize under the new VLC (Visible Light Communications) brand uses OFDM (orthogonal frequency division multiplexing), The article reports the signal can be picked up by simple receivers. As of now, Haas is reporting data rates of up to 10 MBPS (faster than a typical broadband connection), and 100 MBPS by the end of this year and possibly up to 1 GB in the future.

Professor Haas says:

It should be so cheap that it’s everywhere. Using the visible light spectrum, which comes for free, you can piggy-back existing wireless services on the back of lighting equipment …As well as revolutionizing internet reception, it would put an end to the potentially harmful electromagnetic pollution emitted by wireless internet routers and has raised the prospect of ubiquitous wireless access, transmitted through streetlights.

So in 2008, Boston University under a National Science Foundation grant started this research to piggyback data communications capabilities on low-power LEDs to make an LED light the equivalent of a Wi-Fi access point.

Some of the advantages of this technology include:

  • Security: Since white light does not penetrate opaque surfaces such as walls, eavesdropping is not possible and should not extend beyond building perimeters like current Wi-Fi technology. It also requires line-of-sight which will allow the user to see where the data is going.
  • Green: The development of this new technology coincides with the switch from incandescent and compact fluorescent lighting to LEDs. LED lights consume far less energy than RF technology, making it possible to build a communication network without added energy costs and reducing carbon emissions over the long term.

One downside is that the technology seems to be a one-way (down) transmission.

Possible applications could include automotive safety by enabling car brake lights to alert the car behind or traffic signals could alert cars when they change. It could also have applications in indoor mobile location and positioning services.

What do you think?

Does D-Light have a future as a green, wireless access point light?

Put a Hemi in Your Mobile Phone

Put a Hemi in Your Mobile PhoneResearchers at the University of Michigan have found a way to put a hemi into your next mobile phone. While it is not the legendary MOPAR Hemi engine, it is a hemispherical antenna. U of M researchers have figured out how to mass-produce antennas so small that they approach the fundamental minimum size limit for their bandwidth, or data rate, of operation according to the U of M News Service.

University of Michigan logoThe antenna is typically the largest wireless component in mobile devices. Shrinking it could leave more room for other gadgets and features, Anthony Grbic, an associate professor in the Department of Electrical Engineering and Computer Science said.

Mr. Grbic and Stephen Forrest, a professor in the departments of Materials Science and Engineering and Physics, led the development of the hemisphere-shaped antennas, which can be manufactured with innovative imprint processing techniques that are rapid and low-cost. The finished product is 1.8 times the fundamental antenna size limit established in 1948 by L.J. Chu. The dimensions of this limit vary based on an antenna’s bandwidth.

U of M hemispherical antennaEver since the Chu limit was established, people have been trying to reach it,” Mr. Grbic said in the article. “Standard printed circuit board antennas don’t come close. Some researchers have approached the limit with manually built antennas, but those are complicated and there’s no efficient way to manufacture them. We’ve found a way to cut the antenna’s size while maximizing its bandwidth, using a process that’s amenable to mass production.”

The researchers’ prototype operates at 1.5 gigahertz, in the frequency range of Wi-Fi devices as well as cordless and mobile phones. The antenna is 70 percent efficient and ten times smaller than conventional antennas, Mr. Grbic said. It has three times the conductivity of similar devices produced by 3-D ink-jet printing techniques, a process that serially writes the antenna geometry.

This new method is a very general process, said Carl Pfeiffer, a doctoral student in the Department of Electrical Engineering and Computer Science and first author of a paper on the work, “Novel Methods to Analyze and Fabricate Electrically Small Antennas” will be presented at the 2011 IEEE International Symposium on Antennas and Propagation.

It can be used to fabricate antennas that are of a wide variety of sizes, shapes, frequencies, and designs,” Mr. Pfeiffer said. “Basically if you tell me the data rate that is required for a particular application, I can make an antenna that does this while at the same time being as small as possible.

Internet of ThingsThe prototype was made in the College of Engineering’s Lurie Nanofabrication Facility. The work was funded by the Department of Education’s Graduate Assistance in Areas of National Need program, the National Science Foundation, and the U.S. Air Force Office of Scientific Research.

The researchers believe this development could lead to new generations of wireless consumer electronics and mobile phones that are either smaller or can perform more functions. Beyond consumer electronics, this work could be useful in wireless sensing and military communications. Wireless sensor networks could be used for environmental monitoring or surveillance.

Like the Chrysler Hemi, these new antennas may supercharge mobile phones. The small size could allow multiple antennas to be built into mobile devices allowing MIMO connections. The small size should also cut down on the power requirements, decreasing the size of the battery required and increasing the time between charges.

GM Ventures Invests in Powermat

GM logoXconomy – Detroit reports that GM Ventures, the Detroit -based car maker’s venture capital arm has invested $5 million in Powermat the Commerce Township, MI start-up. A multiyear, multimillion-dollar deal with Powermat gives General Motors (GM) exclusive rights to place the company’s portable-device charging technology in its cars for a year. according to Micky Bly, the company’s director of hybrid vehicles. The Chevy Volt and certain Cadillac models will be the first GM cars to the Powermat accessories. The New York Times reports that at this year’s CES GM demonstrated four wireless charging positions in the Chevy Volt.

GM Ventures has also invested in Indiana-based electric car startup Bright Automotive and Ann Arbor-based battery developer Sakti3. Also, see this earlier post.

Car Theft by Antenna

Keyless entryMIT’s Technology Review reports that researchers at ETH Zurich in Switzerland have successfully attacked passive keyless entry and start systems from eight different car manufacturers’. The researchers examined 10 car models from eight manufacturers. They were able to take all 10 by intercepting and relaying signals from the cars to their wireless keys because the key transmits its signals up to around 100 meters. The attack works no matter what cryptography and protocols the key and car use to communicate with each other.

The researchers tested a few scenarios. An attacker could watch a parking lot and have an accomplice watch as car owners entered a nearby store. The accomplice would only need to be within eight meters of the targeted owner’s key fob, making it easy to avoid arousing suspicion. In another scenario, a car owner might leave a car key on a table near a window. An antenna placed outside the house was able to communicate with the key, allowing the researchers then to start the car parked out front and drive away.

The researchers concluded that manufacturers will need to add secure technology that allows the car to confirm that the key is in fact nearby.

New Standard for Automotive-Grade Wireless Modules

Connected carSierra Wireless (SWIR) recently introduced what the firm calls, the industry’s first suite of embedded wireless technology modules designed specifically for automotive manufacturers. The Canadian firm is banking on the emerging trend to include telematics, infotainment, navigation assistance, and remote diagnostics in new cars within the next few years according to an article on ITNewsLink.com. The firm believes these applications will need reliable built-in connections to cellular networks. The new Sierra Wireless modules will use 2G and 3G network technologies and frequency bands used worldwide to provide the connectivity customers are demanding.

The manufacturer says these units are the first wireless modules developed from the ground up to achieve compliance with automotive specifications.  ITNewsLink.com says the Sierra Wireless AirPrime AR Series design encompasses:

  • Tolerance for up to 1,000 thermal shock cycles
  • Full certification with ISO 9001:2000 quality standards and ISO/TS 16949:2002 manufacturing processes
  • Extended operating temperature range from -40 to 85 degrees Celsius
  • Compliance with multiple automotive manufacturing and quality processes including AQPQ, PPAP, PCN, and 8D
  • Solder-down form factor and optional Embedded SIM to create a more reliable and less expensive solution
  • An open platform for custom application development, including dedicated APIs for telematics applications.

Wireless Car Sensors Vulnerable to Hackers

Wireless Car Sensors Vulnerable to HackersMIT’s Technology Review reports that hackers could “hijack” the wireless pressure sensors built into many cars’ tires, researchers have found. Criminals might then track a vehicle or force its electronic control system to malfunction, the University of South Carolina and Rutgers University researchers say. The team successfully hijacked two popular tire-pressure-monitoring systems (TPMS).

As automakers add more technology and computers to cars and connect those computers to critical components, in-car systems will need to be secured against hackers, experts warn.

The systems tested by the South Carolina-Rutgers team had very little security in place–they mainly relied on the communications protocol is not widely published. “In doing TPMS this way, [automakers] have left the door open to wireless attackers,” says Travis Taylor, one of the researchers. The team could eavesdrop on communications and, in some circumstances, alter messages in transit. That let the team give false readings to a car’s dashboard. They could also track a vehicle’s movements using the unique IDs of the pressure sensors, and even cause a car’s ECU to fail completely.

“Normally, these [attacks would] result in small problems,” Mr. Taylor says. “But I see practical danger and damage that can happen from TPMS exploitation.” “The security and privacy problems that the researchers identify in TPMS systems are likely just one among many that will challenge the automotive industry in the years to come,” says Stefan Savage, a UC San Diego professor of computer science and engineering.

Ford Installs Sync Software via Wi-Fi

Ford Installs Sync Software via Wi-FiThe Detroit Bureau reports that Ford is the first automaker to use Wi-Fi to send software to vehicles along an assembly line. The automaker is sending infotainment software to Wi-Fi enabled MyFord Touch-equipped vehicles like the Edge.

Ford installed  Wi-Fi technology at its Oakville, Ontario, plant where it builds the Ford Edge and Lincoln MKX. Next up for Wi-Fi updates will be the upcoming Ford Explorer, built in Chicago, and then plants that build the Focus around the world.

Wi-Fi capability eliminates the need for building, stocking multiple SYNC hardware modules, thus reducing manufacturing complexity and saving cost.  “Using wireless software installation via Wi-Fi, we can stock just one type of SYNC module powering MyFord Touch and loaded with a basic software package,” explained Sukhwinder Wadhwa, SYNC global platform manager. “We eliminate around 90 unique part numbers, each of which would have to be updated every time a change is made – this system really boosts quality control.”

“Turning an assembly plant – with steel beams everywhere and high-voltage cabling throughout; everything you could imagine that would interfere with a radio signal – into an access point that would achieve 100 percent success was a huge challenge,” Mr. Wadhwa said.
