The Global mobile Suppliers Association (GSA) is reporting that LTE Broadcast has attracted the attention of at least 16 mobile network operators, which are trialing or deploying the technology in Australia, China, France, Germany, India, the Netherlands, the Philippines, Portugal, Singapore, South Korea, the United Arab Emirates, United Kingdom and the United States.
TV white space (TVWS), the spectrum that sits between channels in traditional TV band spectrum, continues to generate interest in Africa, and a new trial of the technology in Namibia is being called the largest yet in terms of geography covered.
Every time a new "G" comes around, the engineers try to define what it means in terms of technology. This worked fairly well for 2G, 3G, and 4G, where each generation involved a new way of scrambling the bits for highest spectral efficiency.
Though many in the industry expected September to bring a functional freeze for 3GPP Release 12, this latest set of specifications for LTE-Advanced is now not slated for finalization until December. And the freeze date may be pushed back by an additional quarter as 3GPP works out final kinks in what has become a complicated technology release, according to Said Tatesh, director, 3GPP standards leader, at Alcatel-Lucent.
Its backers no longer call it LTE Unlicensed (LTE-U), though that is an apt description. Regardless, the technology now referred to as Licensed-Assisted Access (LAA) has won kudos for its performance in the 5 GHz band, with tests conducted by Huawei and NTT DoCoMo showing the approach delivers better performance in both coverage and capacity compared with current widely deployed Wi-Fi equipment based on the 802.11n standard.
One of the more interesting filings in the FCC's ongoing 3.5 GHz proceeding is a letter submitted by China Mobile, the world's largest wireless operator, which pushes the TD-LTE agenda.
Ericsson said its latest count revealed 35 percent year-on-year growth in the number of mobile broadband subscribers during the second quarter of 2014, with the total reaching 2.4 billion.
Two law enforcement officials have confirmed they are hoping for reappointment to the board of the First Responder Network Authority, which is charged with planning, building and operating the LTE-based, 700 MHz nationwide public-safety broadband network (NPSBN).
The vast mobile applications ecosystem, enabled by the ability of apps to run on a shared smartphone infrastructure or operating system, has created open doors for hackers that want to obtain personal information from mobile device users. And the threat is believed to extend across Google Android, Apple iOS and Microsoft Windows operating systems, according to a group of university researchers.
Researchers at the University of Michigan have hacked into a live, networked traffic-signal system, showing how lax security can imperil any embedded systems. According to a paper written by the group, they discovered several vulnerabilities in the system's wireless network and its traffic-light controller, which enabled the researchers to alter the state of traffic lights on command.
NTT DoCoMo has announced that it is offering a "premium" public Wi-Fi service, with a maximum speed of 72 Mbps, to travelers within Japan on a trial basis.
The status of voice over LTE (VoLTE) in the iPhone 6 remains unsettled, but there are plenty of signs that Apple is preparing to include the technology in upcoming devices, if not now then sometime in the near future.
T-Mobile US recently posted notably improved latency speeds on its HSPA network, according to research from OpenSignal, which has teamed up with FierceWireless to report network latency speeds of the Tier 1 U.S. wireless carriers.
Consumer demand for both wearables and in-home devices equipped with sensor nodes and wireless links is expected to ramp up substantially throughout the rest of this decade, expanding the reach of the so-called Internet of Things (IoT), according to separate reports from ABI Research and Accenture Interactive's Acquity Group.
A funny thing happened on the way to opening up 500 MHz for fixed and mobile wireless broadband. Reality reared its head, revealing just how challenging it can be to free up spectrum that is already being used for other purposes and hand it over to the wireless industry.
Winners in the upcoming AWS-3 auction may find themselves confronting years of spectrum-coordination challenges as they work to finesse their way through incumbent relocation and frequency-sharing issues, according to Chris Hardy, general manager of CommScope subsidiary Comsearch.
Intel's acquisition of LSI's Axxia Networking Business, a provider of system-on-chip (SoC) solutions for network infrastructure, will be a crucial driver in the development of Intel's wireless-access-networking strategy and its long-term goal of running critical network workloads on a single architecture, said Rose Schooler, general manager of Intel's communications-infrastructure division.
Juniper Research predicts that the value of the mobile context and location-based services (LBS) market will more than triple in the next five years, thanks in large part to the adoption of highly targeted and context-aware ad-supported apps, which will account for over two-thirds of revenues.
The FCC's proposal to open up more of the 5 GHz band for use by unlicensed devices continues to draw criticism and generate debate in multiple corners, as supporters of the commission's plan square off against critics that are concerned about the proposal's impact on vehicle-to-vehicle (V2V) communications and wireless Internet service providers (WISPs).
AT&T has made AT&T Stadium, home of Dallas Cowboys football, a showcase for its wireless services, with an extensive Wi-Fi network, enough cellular-network capacity to serve a small suburb and the first stadium LED display built to respond directly to fans.
