  • So WIFI waves are basically just radio waves, so that's the same as the electromagnetic waves you pick up with your cell phone or a radio.

    WIFI 基本上是種無線電波,所以跟你的手機或收音機所發出的電磁波是一樣的東西 。

  • But wifi waves are fairly short. They're only 12 cm long, the conventional kind.

    但是 WIFI 的波長較短,一般型的只有 12 CM長。

  • Compare that to AM radio waves, which are hundreds of meters long.

    和 AM 調頻數百公尺的波長相比要短得多。

  • The signal gets a lot weaker as it gets further from the router.

    WIFI 訊號強度會在從路由器發出後隨著傳遞距離增長而減弱。

  • And generally they can't go more than 150 feet from a single router.

    單一路由器的訊號通常無法傳遞至 150 呎外。

  • They actually get absorbed and blocked by walls and metal surfaces.

    WIFI 訊號也容易被牆面、金屬面吸收及阻擋 。

  • And so the way, the way you position your WIFI router makes a huge difference in how strong your signal is throughout your house.

    所以 WIFI 路由器放置的位置,會對其在家裡各處的訊號強度造成莫大影響 。

  • One thing you definitely want to do is put your router near the center of your house. [Place your router out in the open]

    首先,你最好把路由器方放在家裡的中心地帶。[將路由器放在空曠處]

  • Because it broadcasts the signal out in equal strength in all directions.

    因為這樣才能讓 WIFI 訊號強度均勻地傳遞到各個角落。

  • So you want it out in the open, like If it's in a closet, the walls of the closet are going to absorb and block some of the signal.

    所以最好放在開放式空間中。如果放在衣櫃之類的地方,那麼衣櫃的牆面就會吸收及阻擋掉部分訊號。

  • A good way to think about it is just use line of sight.

    最好的方法就是用視線來判斷該放在哪裡。

  • From whatever position you can see the furthest in your house and you can see the most number of rooms, that's probably a good place to put your router.

    可以看到家裡最遠和最多房間數的地方,就是個放路由器的好地方。

  • You also really want to lift your router up off the ground, because the signals can't penetrate some of the materials that make up floors, like metal, or concrete, or cement. [Lift your router off the ground]

    同時,要將路由器置於高處並遠離地面。原因是WIFI訊號無法穿透一些如金屬、 混凝土、水泥等的地板建材。[將路由器置於高處]

  • And also, the way most routers are designed, they broadcast the waves slightly downwards, so that way you're projecting less of it down into your basement for no reason.

    另外,大多的路由器被設計成以稍微朝下的方向傳遞訊號,因此放在地面上只會讓你毫無理由地朝著地下室傳遞訊號而已。

  • A lot of other electronics can interfere with the router's signal, things like TVs, computers, microwaves, pretty much anything that has a motor inside it. [Keep it away from other electronics]

    許多電子產品都會干擾路由器所發出的訊號。例如:電視、電腦、微波爐等,可以說是幾乎所有裝有馬達的產品。[遠離其他電子產品]

  • So you want to keep the router away from other electronics.

    所以你最好讓路由器遠離其他電子產品。

  • Most routers have two antennas on them, and ideally you could position one of them vertically and one horizontally. [Point the antennas in different directions]

    大多數的路由器有兩根天線。理想上一根應與地面垂直,另一根則與地面水平。[將天線朝向不同方向]

  • Devices work best when their internal antenna is parallel with the router's.

    當裝置的天線與路由器的天線呈平行時功效最好。

  • And so most antennas inside laptops are horizontal, but if you're using a mobile device or a tablet, it totally depends on how you're holding it.

    所以大多筆記型電腦的天線設計是與地面水平的,但如果你用的是手機或平板,那就得看你的持握方式了。

  • So that way if you have one horizontal and one vertical, you have the highest chance of having a parallel match with antennas.

    將一根天線與地面水平,另一根天線則與地面垂直的話便能更有機會讓裝置的天線與路由器的天線平行。

  • If you find that your network isn't working well, you can just go around and measure your signal strength. [Measure your signal strength]

    如果你發現網路連線狀況不好的話,你可以四處走動並測量訊號強度。[測量訊號強度]

  • So there's a lot of apps that you can download on your phone.

    現在手機上有很多應用程式可供下載使用。

  • You could create a rough map and figure out what you need to do to fix it.

    你可以藉此繪製出一張訊號地圖,瞭解哪些地方訊號微弱並需要加強改善。

So WIFI waves are basically just radio waves, so that's the same as the electromagnetic waves you pick up with your cell phone or a radio.

WIFI 基本上是種無線電波,所以跟你的手機或收音機所發出的電磁波是一樣的東西 。
