Mr Deng's IT News Collection: High-speed LTE networks could be felled by a $650 piece of gear, says a new study. Any radio frequency can be blocked, or “jammed,” if a transmitter sends a signal at the same frequency, with enough power. But LTE turns out to be especially vulnerable, Reed’s group says. That is because the whole LTE signal depends on control instructions that make up less than 1 percent of the overall signal.
