Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
The Q-code is a standardised collection of three-letter codes that each start with the letter "Q". It is an operating signal initially developed for commercial radiotelegraph communication and later adopted by other radio services, especially amateur radio.

Keyboard and keypads must be secure.

The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy ( Morse code ). An enhanced format, SINPO code, was published in the ITU Radio Regulations, Geneva, 1959, [1] but is longer and unwieldy for use in the fast pace of Morse code communications.
