In an effort to increase the transfer speed of stock market information, several stock exchange operators are investigating the use of microwave links to relay data faster than the ability of existing fiber-optic cables. CME Group Inc. and Nasdaq OMX Group Inc. are in the process of exploring a joint venture to relay prices and other market information between New York and … [Read more...]
New Filters Prevent Interference Between VHF and TETRA Radios
Procom, a supplier of antennas, filters and combiner equipment, has released two new filters designed to prevent interference between VHF and TETRA radios. According to the company, the LP 170-FMA is a low-pass filter with a passband of 0-174 MHz and a stopband of 380-1000 MHz. When inserted into the VHF radio antenna cable, the filter protects the TETRA radio from interfering … [Read more...]

'Electromagnetic Armageddon’: Theory Suggests Sun-Grazing Comets May Spark Global Electronics Meltdown
An upcoming paper to be published in Astrophysical Journal Letters suggests that sun-grazing comets could trigger a cosmic ray shockwave large enough to disable the world’s electronics in a manner usually associated with electromagnetic pulse weapons or nuclear warfare. According to David Eichler, an astrophysicist at Ben-Gurion University of the Negev in Beer-Sheva, Israel, a … [Read more...]
New Wireless Technology Developed to Increase 3G and 4G Network Efficiency
In an effort to resolve the ongoing available spectrum issue, researchers at the University of California at Riverside have developed a way to double the efficiency of wireless networks. The researchers theorized that the use of modified full-duplex radios, which transmit signals at the same time in the same frequency band, could double the efficiency of the spectrum. Current … [Read more...]
Declassified Document Reveals Plans to Create EMP “Seizure Weapon” Inspired by Pokemon
A declassified document recently released by the Army’s National Ground Intelligence Center revealed development plans for a military “seizure weapon” inspired by a controversial episode of the popular Japanese children’s cartoon Pokemon. The episode was pulled from American programming in 1997 after symptoms of epilepsy were induced by rapidly flashing images in several … [Read more...]
