Conversion from analog television in the United States combined with the appeal for broadband public safety communications is generating a lot of interest in the so-called 700 MHz band between 698-806 MHz. To our knowledge, no channel propagation model for this band exists to date. In this work, we derive such a model reduced from a measurement campaign realized through a stepped frequency system. The campaign includes 89 transmitter-receiver configurations in seven different environments relevant to residential, commercial and public safety communications, ranging from subterranean mine tunnels to an oil refinery, from mid-size to high-rise buildings. The stochastic impulse response model is complete with 17 parameters which enables reconstruction for use in simulation engines, amongst others.
