IN MY OPINION

The Multidimensional Alan Borck
By Charles Alan Borck, Founder, RLC Electronics

Charles Alan Borck, founder of RLC Electronics in Mt. Kisco, NY, died on March 1 at 87.

No one who ever did business with Alan Borck would ever consider him indecisive or indirect. While he was a man of few words, they were always what he believed to be the truth, like them or not. Alan was a stand-up guy, and a very bright one as well.

Uncertain Times for DefenseAnother Sad Moment For the FCC
By Barry Manz

A significant number of rooftop antenna sites owned primarily by wireless carriers exceed FCC public and occupational exposure limits, make it impossible for workers to avoid standing in front of antennas, and are inadequately posted with warnings and barriers. Read More...

  • Russia is considering building a giant solar-energy plant in space, from which electricity could be generated and directly transmitted to Earth using microwave energy.
  • In the wireless industry’s never-ending quest to grab spectrum where it can find it, the CTIA has asked the FCC to reallocate 15 MHz of contiguous spectrum for wireless use, suggesting that the Broadcast Auxiliary Service (BAS)
  • The goal of DARPA’s Shared Spectrum Access for Radar and Communications (SSPARC) program is to radar and communications capabilities through spectrum sharing, an issue of increasing severity as the spectrum below 6 GHz
  • The Critical Communications Broadband Group, a working group of the TETRA & Critical Communications Association says that depoyfment of LTE for public safety applications won’t come until 2018 for data and voice over LTE until 2020
  • A story in C4ISR Journal about the crash of a Broad Area Maritime Surveillance-Demonstrator (BAMS-D) UAV that crashed into swampland on an island in the Chesapeake Bay on Maryland’s eastern shore on June 11, 2011
  • Verizon, which vacuumed up a lot of AWS spectrum from cable companies for $3.6 billion, is finally about to use the band at 2 GHz, effectively creating another LTE band in addition to its allocation at 700 MHz, potentially doubling its capacity.
  • The FBI has been asked by Singapore law enforcement officials to investigate the death of Shane Todd, a scientist working on gallium nitride research in that country.
