The official study guide for the Certified Wireless Design Professional (CWDP) exam from CWNP!

This official guide is what you need to prepare for the vendor-neutral CWDP exam (PW0-250), which tests an IT professional’s ability to design, plan, and troubleshoot a wireless network. Administered by CWNP, the industry leader for enterprise Wi-Fi training and certification, the CWDP exam is for those operating in large WLAN deployments. This practical guide not only covers all exam objectives, it also gives you practical information on designing for complex environments such as businesses, hospitals, educational facilities, and in outdoor spaces. 

  • Covers all exam objectives for the Certified Wireless Design Professional (CWDP) exam, exam PW0-250
  • Covers planning, developing a WLAN design strategy and RF, conducting advanced site surveying, developing 802.11 security, and troubleshooting
  • Companion CD includes two practice exams and over 100 electronic flashcards
  • Sybex is the official publisher for Certified Wireless Network Professional, Inc., the certifying vendor for the CWAP program

If you want to prepare for CWNP certification, a  Sybex Study Guide is what you need!

demand in the consumer market, the economic motivation for chipset vendors to develop enterprise-only features is minimal. This is important to keep in mind when you, as a WLAN designer, are researching feature support with equipment vendor products. While Wi-Fi will continue to grow in the consumer market, it will also continue to grow in the enterprise market. To draw a parallel to another industry, automobile manufacturers do not participate in the Formula One racing events because they will

Point-to-Multipoint Links PtMP links can be very different design scenarios compared to PTP links. PtMP links often involve employing traditional APs using bridge link modes, but you may use products from PTP bridge manufacturers as well. PtMP links are often used when access to network resources from one location needs to be given to several remote locations. These remote locations may be relatively adjacent buildings or perhaps even separated by some distance. Let’s start with a simple

most vendors are also adding better configuration options to tailor these features to your AP layout. This often includes sensitivity settings for power changes as well as scan intervals. There is another point you should understand before performing an RF analysis of a new network. If an automated RF management system is in use and transmit power settings between APs are widely variant, you will also likely find that the actual transmit power settings vary considerably from the original,

key stakeholders, but out of ignorance they didn’t spend the extra $15 per client radio upgrade in their laptops and ended up with a 2x2 802.11n chipset versus a 3x3 one. The 3x3 chipset would result in better radio performance in both throughput and stability. Receive Sensitivity Earlier we said that radios are similar to humans in how well they receive and give information. Like people—some of whom have better hearing than others—radios can receive in different ways. Some radios simply have
