3 Mar. 7 doc.: IEEE c Suary Current kiosk environent (UM5) epoys LOS office channe ode (CM3) Soe channe ode users caied that the channe ode for UM5 contains excessivey strong refections We re-easured the propagation characteristics of the kiosk environent and created a new channe ode We suggest that the new channe ode be added on the current ode (UM5) Side 3

4 Mar. 7 doc.: IEEE c Probe of kiosk (UM5) channe ode Kiosk and office environents are quite different The eta was of offices cause strong refections, however, this is not true for kiosks In kiosk environents, distance between server and PDA is and huan body bocks arge deay refection waves, so the deay spread wi be saer than that in LOS office environents More suitabe channe ode for kiosk environents is required Side 4
