ZK Celltest, a world leader in wireless network drive test solutions, today announced that the following post-processing data analysis software companies and products support ZK's open log file format data:

"Wireless carriers do not want to be locked in to buying a software mapping product from a drive test hardware manufacturer. When the customer has a choice they invariably get a better product at a lower price with better service from more specialized vendors.", says Rich Miletic, CEO of ZK Celltest, Inc. "We offer a complete solution through our mapping and drive test products, however we strongly believe in open file formats so customers retain their flexibility of choice and it is great to see such a broad range of independent suppliers supporting that openness."

ZK Celltest family of products supports the full spectrum of CDMA, EVDO Rev. O and A, iDEN, GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA and 4G standards. ZK Celltest solutions are dedicated, non-PC, products designed from the ground up for use in the field. Eliminating the need for a laptop makes ZK's solutions ideal for drive testing, where drivers must keep their attention on the road rather than on a laptop screen, and for in building use where the product is lightweight, performs indoor benchmarking and logs data to a floor plan bitmap image right on the display.
