近來在找天線的資料
2.4G WIFI 天線 2400 mhz-2500mhz
4G LTE 天線 700mhz-2700mhz
5G 天線 600mhz -6000mhz
按照字面上的頻率，5G 天線接收的範圍已經包含
2.4 G 和 4G 的範圍
請問，為什麼還要分這麼多種啊？
全部接5G天線不就全包了？
小弟不才，GOOGLE了半天還是找不到資料。
勞請高手解惑

Low-band 5G uses a similar frequency range to 4G cellphones, 600–850 MHz, giving download speeds a little higher than 4G: 30–250 megabits per second (Mbit/s).[5] Low-band cell towers have a range and coverage area similar to 4G towers.
Mid-band 5G uses microwaves of 2.5–3.7 GHz, allowing speeds of 100–900 Mbit/s, with each cell tower providing service up to several kilometers in radius. This level of service is the most widely deployed, and should be available in most metropolitan areas in 2020. Some regions are not implementing low-band, making this the minimum service level.
High-band 5G uses frequencies of 25–39 GHz, near the bottom of the millimeter wave band, although higher frequencies may be used in the future. It often achieves download speeds in the gigabit per second (Gbit/s) range, comparable to cable internet.
