2.4ghz 5ghz分別 2.4GHz?

現在比較新的wifi分享路由器,都會有2個頻段,分別為2.4 GHz以及5GHz兩個可以做選擇,但這兩個到底有什麼差別?要怎麼做選擇呢? 2.4和5後面的「G」是十億的意思,則「HZ」則是頻率單位「赫茲」的縮寫,也就是說,2.4Ghz就是一秒震動24億,來傳送資料
Wi-Fi 網路中,2.4GHz 和 5GHz 各自有哪些優缺點?
2.4Ghz下,衍射和反射比5Ghz要多,因此設備接受到的信號反而強。 無線網路信號的本質是電磁波,電磁波的傳播速率等於頻率與波長的乘積,而這個乘積實際上是一個固定值,就是光速,換句話說電磁波的頻率越高,波長就越短,因此5GHz信號的波長顯然要比2.4GHz信號的要短,而波長越短的電磁波穿透
2.4GHz WiFi covers a longer range than 5GHz WiFi, making it ideal if you need the signal to reach a larger area, such as large retail shops, bars with different floors and hotels with a pool area. Without taking any external factors or major obstacles into consideration, a lot of standard WiFi routers operating on the 2.4GHz frequency can reach up to 150 feet (46m) indoors and 300 feet (92m
The 2.4GHz frequency is way more crowded than 5GHz, devices on 2.4GHz suffer much more interference than the ones on 5GHz; Fewer devices are capable of using the 5GHz channel than the 2.4GHz channel. If there is too much interference around and your clients support 5GHz, it’s recommended to use 5GHz wireless network, otherwise you’d better select 2.4GHz.

6/7/2014 · IEEE 802.11ac,俗稱5G WiFi (5th Generation of Wi-Fi)[1][2],是一個802.11無線區域網路(WLAN)通訊標準,它透過5GHz頻帶進行通訊。理論上,它能夠提供最少1Gbps頻寬進行多站式無線區域網通訊,或是最少500Mbps的單一連線傳輸頻寬。
路由器的2.4GHz?5GHz是什么?速度有何分別?_WiFi
2.4GHz和5GHz 在2.4GHz和5GHz之間的選擇也不難理解:2.4GHz可以提供數值的范圍,但信號較弱;而5GHz可以提供更強的信號,但距離接近。這是簡單的物理理論,在較高的頻率下,波會重啟地衰減,對于WiFi信號和在其他任何情況下都是一樣的,使用5GHz

You should not use a 2.4 antenna on a 5ghz radio as the antenna is made for the 2.4ghz only. Go buy a dual mode antenna then, this way it’s built for either radio band. There are more post saying you shouldn’t, than post saying that it works.

I’ve connected my smartphone to the 5GHz WiFi supplied by the 1200+ home plug and I can communicate with items on the 2.4GHz band. No issues so far, like how I saw when 5GHz was enabled on the SH2. It’s early days as I will need to try plugging the 1200+ nearer to the network source plug, as the download speeds are not as fast as I expected (compared to that of the SH2 when the 5GHz band …
