WebbThis enterprise class 802.11ax ruggedized indoor/outdoor AP provides three radios. As a top-of-the-line Wi-Fi 6 access point it provides OFDMA, a 2.5 Gigabit Ethernet port, plus an additional 1 Gbps Ethernet port with PoE out. The AP can provide 24/7 scanning across both bands while still providing access on both the 2.4 GHz and 5 GHz bands. WebbThe OFDM scheme differs from traditional FDM in the following interrelated ways: 1. Multiple carriers (called subcarriers) carry the information stream, 2. The subcarriers are orthogonal to each other, and. 3. A guard interval is added to each symbol to minimize the channel delay spread and intersymbol interference.
