Do wireless keyboards send data to the computer using microwave frequencies?
Whether a wireless computer keyboard uses microwave frequencies for communication with the computer depends on the technology used by the keyboard, and on the definition of microwave frequencies. Wikipedia defines microwave frequencies to be in the 1...30GHz range. Many wireless keyboards operate in the 2.4GHz band, which would make them microwave transmitters (and receivers). Other keyboards use different frequencies, below 1GHz. Those would not be microwave devices, according to this definition. The 802.15.4 standard, for example, lists a 868.0-868.6MHz band (Europe), 902..928MHz (US) and the 2.4GHz (2400...2483.5 MHz) band (worldwide, but subject to regional restrictions).

Instead of wasting valuable time downloading the portion you have received before the transfer was interrupted, SmartCP transparently continues the download from the last know good point. Anyone who has spent many hours or even days downloading a file only to find that they have been disconnected with only 99% of file received knows the thought of all time in anticipation going to waste makes SmartCP a welcome addition to the modem.SmartCP History:Prior to SmartCP less than successful attempts were made to solve the 'resume download' problem via software and software protocols. Lack of a proper industry standard meant that many sites, services and software packages were either incompatible with each other or did not support the option at all.
