About the CWTS Certification

The Certified Wireless Technology Specialist (CWTS) is a vendor-neutral certification administered by CWNP. This brand new certification is the only entry-level vendor neutral wireless certification for IT Professionals, and was developed for IT support staff who work with wireless technologies. It is a springboard to the foundation-level Certified Wireless Network Administrator (CWNA), and more advanced Certified Wireless Security Professional (CWSP) and Certified Wireless Network Expert (CWNE) certifications. The exam is offered in over 100 countries through both Prometric and Pearson VUE testing centers. The cost of the exam is $125.

Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.
