Bonding channels increases throughput, which can improve performance. Thus, the difference between 20 MHz and 40 MHz is throughput. 40 MHz has higher throughput than 20 MHz thanks to channel bonding. …. While 40 Mhz might have higher throughput than 20 Mhz, it also reduces the number of non-overlapping channels. High-density Wi-Fi is a design strategy for large deployments to provide pervasive connectivity to clients when a high number of clients are expected to connect to Access Points within a small space. (some will support 20-Mhz, some will support 40-MHz and some will support 80-Mhz channels). Due to this, it is better to have each client First read Basic Wireless Settings. 20MHz vs 40MHz. The N spec is able to use 40MHz of bandwidth for increased data rates, but to maintain compatibility with legacy systems, it requires one main 20MHz channel plus a free adjacent channel at ±20MHz. The main channel is used for legacy (a/b/g) or other clients that aren't able to transmit at 40MHz. Learn the difference between 2.4 GHz and 5 GHz Wi-Fi bands, and how to choose the right channel width for your Wi-Fi performance. Find out the advantages and disadvantages of using 20 MHz, 40 MHz, and 80 MHz channel widths, and how to optimize your Wi-Fi network with best practices and tips. 25/2/2018 20:53Phản hồi: 7. Wireless router có mục settings wireless, trong đó có phần Channel Width (độ rộng của kênh) gồm hai mức băng thông là 20Mhz hay 40Mhz. Việc lựa chọn băng thông này ảnh hưởng trực tiếp đến tốc độ truyền dữ liệu giữa router và thiết bị nhận. Trong bài Vay Tiền Nhanh Chỉ Cần Cmnd Nợ Xấu.
