Researchers in the Cockrell School of Engineering at the University of Texas at Austin have designed an antenna that can break reciprocity without requiring additional expensive electronic components.
As the FCC prepares to begin its incentive auction of 600 MHz of TV broadcasters' spectrum, a new issue is rearing its head. "Repacking" channels after the auction into new areas of the remaining broadcaster spectrum will require installation of new antennas and RF equipment for many stations that stay on the air, rather than opting to stream their signals online or merge with other stations.
L-Com Global Connectivity, a connectivity product manufacturer, has recently announced the release of two multiple-input, multiple-output (MIMO) antennas which the company says provides "true" 180-degree coverage.
Connectivity product maker L-com Global Connectivity is adding a new antenna to its HyperLink brand. The HG72705CUPR-NF antenna is an omnidirectional ceiling-mounted device that L-com said is tailored to in-building wireless networks, like distributed antenna systems (DAS).
PCTEL recently introduced new compact panel antennas to its VenU line of broadcast access products. The new antennas offer 3-port and 4-port MIMO options, which support "dual-band coverage for high-speed 802.11ac Wi-Fi networks covering both 2.4-2.5 GHz and 4.9-5.9 GHz on each port."
Researchers from the UK's University of Cambridge say they have unraveled one of the mysteries of electromagnetism, a breakthrough that could enable the design of antennas small enough to be integrated into an electronic chip. The development could have implications for the Internet of Things (IoT).
Over-the-air video service TabletTV is moving forward with its plans to step into the space left by Aereo, launching in the San Francisco Bay area following several weeks of beta testing.
NTT DoCoMo showed off its multi-element antenna/circuit integration technology for 5G, and this time, the company revealed an ultra-thin filter.
In an expected move, Aereo will shutter its Boston office on Nov. 12, a move that will see 43 employees laid off. The online video provider will also lay off an undisclosed number of employees at its New York City headquarters.
The steadily rising numbers of antenna sites for cellular networks, many of which are being deployed in stealth fashion for aesthetic appeal, are raising eyebrows among those concerned about the impacts of excessive radio-frequency (RF) radiation.
