 Knowledge is power. More to the point, knowledge of radio frequency energy is the surest way for a wireless worker to protect himself from being exposed to dangerous levels of RF radiation. LBA Group, in cooperation with university educators, has developed the OSHA RF awareness course with certificate of completion so that wireless tower workers [...]  The rollout of 3G networks across the country is old news with the recent announcements by Verizon, AT&T, and others to rapidly deploy 700 MHz 4G LTE this year throughout the USA. These high speed networks are slated to grow with ten’s of thousands of new towers and antennas, and to employ novel digital modulation [...]  Last time we introduced the new buzzword term, the utility Smart Grid, provided a quick overview of the concept-undergoing-creation, and noted that doubts exist whether the utility industry can successfully implement it. Now let’s spend a little time examining those doubts as they relate to the utility-centric side of the Smart Grid effort. The first [...]  The FCC requires that all 2600 MHz band BRS and EBS broadband licensees who would must demonstrate that they provide “substantial service” to actual customers no later than May 1, 2011. Failure to meet this requirement will result in forfeiture of the license and the licensee will be ineligible to regain it. Various “safe harbors” [...] There is a new “next great thing” concept now moving through the land, undergoing promotion in the popular press and probably destined to be a future concern (and cost burden) to the citizens of the United States. That term is “Smart Grid.” And it’s a term that would be much easier to deal with if, [...]  It is our experience that RF safety accountability and hazard avoidance is well established in the wireless communications sector. However, hazardous industrial RF is widely encountered in a wide variety of industry settings through all manner of process equipment and non-radio systems. Many of these systems are benign just out of the manufacturer’s shops, but [...] It has become increasingly popular to install bi-directional amplifiers (BDA’s) and distributed antenna systems (DAS’s) to overcome problems of cellular and other wireless coverage within buildings. Properly engineered, and coordinated with the cell cos being retransmitted these can greatly help in overcoming building problems. However, these systems are readily available, and are increasingly being installed [...] |
