CWNP CWISA-102 Exam With Confidence Using Practice Dumps

• PoE Splitter: A PoE splitter separates power and data from a PoE-enabled Ethernet cable, allowing the powering of non-PoE devices.
• Other PoE Devices:

• 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.

• Wireless Network Topologies (PtP vs. PtMP): Explanations of the differences in how communication is managed in each scenario.
• TDMA (Time Division Multiple Access): A common airtime sharing method used in PtMP systems.

• ZigBee Channel Spacing: ZigBee channels in the 2.4 GHz band are spaced 5 MHz apart. This helps manage interference in the crowded 2.4 GHz spectrum.
