Cyber Attacks on Cellphone Batteries | | Draining cellphone batteries is a new sport by hackers. By usurping control of communications channels that a cellphone uses for broadband data transfer, an attacker repeatedly awakens a victim phone from its low-power mode. Verification tests were run on a Nokia 6620 phone at UC Davis that were able to reduce a battery's lifetime from 156 hours to a mere 7 hours from a fully-charged state. The process was carried out through two commercial networks without triggering any intruder alarms. |

Perfect 2-Carat Man-Made Diamonds |  Perfect single-crystal diamonds of more than two carats are churned out in a single day. The gemstones are created using a process called chemical vapor deposition (CVD), which grows diamond crystals one carbon atom at a time. CVD is the same technique used to process many semiconductor circuits. |

Gallium is a byproduct of smelting aluminum and zinc, and is more rare than gold. It, along with mercury, cesium, and rubidium, are the only metals which can be liquid near room temperature. Arsenic is a deadly poison that is made by heating composite minerals in the absence of air. Acting together in compound form, gallium arsenide (GaAs) has been the basis of the personal communications revolution. |

| The world is running out of Internet addresses. No worries, however, because Internet Protocol version 6 (IPv6) will solve that problem by providing up to 2128 unique IP addresses. That is the equivalent of roughly 2,000 addresses for every square meter on the Earth's surface. Question: If IPv6 replaces IPv4, what happened to IPv5? |

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
