CWISA-102 Exam Dumps : Certified Wireless IoT Solutions Administrator

• IP Ratings & Manufacturing: IP66 provides:
• Harsh Manufacturing Environments: IP66 is common due to dust, dirt, and potential exposure to liquids during cleaning or spills.

• PtMP (Point-to-Multipoint): A single access point (AP) communicates with multiple client devices. This means the AP needs to manage how the available airtime is shared among those clients.
• Airtime Fairness: Mechanisms are needed to ensure that:
• PtP (Point-to-Point): A dedicated link only has two devices, eliminating the need for complex airtime management.
• Considerations in Both: While interference, SINR, and frequency selection are important in both PtMP and PtP systems, the need for airtime management is unique to the multipoint scenario.

• Coexistence Priority: Frequency coordination is the most critical aspect in ensuring that multiple wireless solutions function without significant interference.
• Impact of Interference: Uncoordinated frequencies lead to:
