1. A dual-mode ultra wideband and wireless local area network transceiver comprising:

  • a digital lowpass-shaping finite impulse response filter system coupled to a ultra wideband multichannel pseudorandom noise sequence mapping or a wireless local area network inverse fast Fourier transform and in-phase/quadrature modulation;

    a dual-mode sampling frequency rate coupled to a digital-to-analog converter, said digital lowpass shaping filter system coupled to said digital to analog converter;

    a switch to connect from the ultra wideband multichannel pseudorandom noise sequence mapping or the wireless local area network inverse fast Fourier transform and in-phase/quadrature modulation to the digital lowpass-shaping filter system.
