Reston, VA-- Comsearch has been selected by PCIA to provide frequency coordination services for PCS '99. Comsearch will provide these services to exhibitors who require frequencies in the 1.9-GHz band for product demonstrations. TeleCorp has granted temporary use of their licensed spectrum for this purpose.
