A transportable microwave frequency standard based on laser-cooled 113Cd+ ions is introduced, and its working principle and potential performance are discussed. Based on the experimental setup developed at JMI, the frequency of the ground-state hyperfine splitting of 113Cd+ is measured to within milliHertz uncertainty and its frequency stability is obtained.
