As Wi-Fi access points become smarter (for example, Huawei access points utilize smart antennas and SmartRadio channel calibration technologies), planning and maintaining Wi-Fi networks has become significantly easier than before.<\/p>\n<p>Sometimes this can even be done without hiring professional engineers, who used to be required even for simple scenarios.\u00a0<\/p>\n<p>It should be noted that complex and critical implementations still require careful radio planning and radio modeling of the wireless network by professional engineers and architects.\u00a0<\/p>\n<p>Wireless 5G networks always require thorough planning, modeling, and controlled deployment at all project stages, whether starting from scratch or expanding the coverage area of the telecom operator.<\/p>\n<p>Thus, the overall costs of launching a network vary significantly.<\/p>\n<h3>Different ways to promote 5G and Wi-Fi 6 terminals:<\/h3>\n<p>\nThe cost of promoting Wi-Fi 6 terminals is lower.

Although, of course, there are assumptions and exceptions here as well.<\/p>\n<p>Therefore, using Wi-Fi 6 is preferable for end devices that weren't intended to support 5G, such as printers, electronic boards, smart building management systems, projection TVs, and telepresence systems.\u00a0<\/p>\n<h2>Interaction between Wi-Fi 6 and 5G:<\/h2>\n<p>\n5G networks have some limitations, such as the high cost of indoor coverage and the inability to upgrade older devices.\u00a0<\/p>\n<p>Wi-Fi 6 technology addresses issues related to high bandwidth, large capacity, and low latency in indoor coverage scenarios.\u00a0<\/p>\n<p>Due to these advantages, Wi-Fi 6 is suitable for key applications that require high bandwidth and low latency, such as VR\/AR, 4K\/8K content, and automated guided vehicles (AGVs).\u00a0<\/p>\n<p>Thus, for enterprises, Wi-Fi 6 networks and 5G can interact with each other in most scenarios in a synergistic mode to achieve an optimal access and coverage ecosystem.\u00a0<\/p>\n<p>For certain industrial scenarios, such as oil fields, coal mines, and AGVs, 5G has unique advantages, including low latency and wide area coverage.<\/p>\n<p>In scenarios with very high street placement density (for example, in squares and stadiums), the bandwidth of 5G networks may not always meet user access demands without adding a significant number of base stations.\u00a0<\/p>\n<p>In this case, the high access density of Wi-Fi 6 is a cost-effective solution for servicing a large number of users and terminals with high density.<\/p>\n<h2>Output:<\/h2>\n<p>\nDespite similar physical technologies, the application areas of Wi-Fi 6 and 5G differ in terms of industrial scenarios, as well as the costs of implementation and ownership. <\/p>\n<p>Therefore, the conclusion about 'which is better' will be best illustrated with a picture!<\/p>\n<p><img decoding=\"async\" alt=\"Similarities and Differences Between Wi-Fi 6 and 5G\" src=\"\/wp-content\/uploads\/2020\/06\/74235d231337e636fe204d02495ea2e2.jpg\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<br \/>\nI hope this material has been useful and helped clarify the main key elements of the similarities and differences between these technologies.<br \/>\n<br \/>Source: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/company\/huawei\/blog\/505042\/\">habr.com<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u0447\u0435\u043d\u044c \u0447\u0430\u0441\u0442\u043e \u0441\u043b\u044b\u0448\u0443\u00a0\u0441\u043f\u043e\u0440\u044b \u0432 \u043f\u0440\u043e\u0444\u0435\u0441\u0441\u0438\u043e\u043d\u0430\u043b\u044c\u043d\u043e\u0439 \u0438 \u043e\u0431\u044b\u0432\u0430\u0442\u0435\u043b\u044c\u0441\u043a\u043e\u0439 \u0441\u0440\u0435\u0434\u0435 \u043f\u0440\u043e Wi-Fi 6 \u0438 5G. \u0427\u0442\u043e \u043b\u0443\u0447\u0448\u0435?
