Most people think of backup communications options.

大部分人會想到備援通訊選項。

They think of something that looks like this.

There's more out there that we can consider as options.

外面還有更多我們可以考慮的選項。

Today we're going to talk about some of the options that exist and how Meshtastic compares to these options.

今天我們要來聊聊現有的幾個選項，以及 Meshtastic 和這些選項相比如何。

Although meshtastic isn't perfect, it does have some unique benefits that none of the others can claim.

雖然 Meshtastic 並不完美，但它確實有一些獨特的優勢是其他選項無法比擬的。

Make sure you stick around until the end because you'll definitely want to hear about the pros that Meshtastic has to offer.

請務必看到最後，因為你絕對想聽聽 Meshtastic 提供的優點。

Foreign let's first talk about handheld radios.

首先，我們來聊聊手持無線電。

That could be ham radio, GMRS or even just a basic walkie talkie using frs.

這可能是業餘無線電、GMRS，甚至是使用 FRS 的基本對講機。

Quick recap for anybody that doesn't know a lot about these things.

快速複習一下，給不太瞭解這些東西的朋友。

So ham radio requires a license that you get through the fcc.

所以業餘無線電需要一個你透過 FCC 考取的執照。

GMRS requires a license as well, but it's just pay to play.

GMRS 也需要執照，但它就是付費就能玩。

Your entire family can communicate using GMRS systems on one of the radios I just showed you.

你的全家人都可以用我剛才展示的其中一臺無線電，透過 GMRS 系統溝通。

FRS doesn't require a license at all, but they are a lot lower power.

FRS 完全不需要執照，但它們的功率小很多。

Let's do a quick recap for anybody who's not familiar with ham radio, GMRS or frs.

我們快速複習一下，給還不太熟悉業餘無線電、GMRS 或 FRS 的朋友。

Ham radio and GMRS each require a license.

業餘無線電和 GMRS 都需要執照。

For GMRs, it's essentially pay to play gets you access for 10 years for your entire family.

GMRS 基本上就是付費就能玩，而且全家人都能用十年。

FRS uses much lower power radios, but they don't require a license at all.

FRS 使用的無線電功率小很多，但完全不需要執照。

Think of this like your typical walkie talkie.

想像一下，這就像你平常在用的對講機。

What what they all have in common is their mode of operation.

And what I mean by that is how you actually use the device to communicate, and that's voice.

我說的操作模式，就是你實際用裝置溝通的方式，也就是語音。

Now, ham radio operators, before you run to the comments and talk about digital modes, I'm keeping this simplistic.

那，業餘無線電玩家們，在你們衝到留言區討論數位模式之前，我這裡講得比較簡單。

Now, most of the time, voice is completely sufficient for communicating with a radio.

大多數時候，語音溝通就已經很夠用了。

This is the standard way people use radios.

這是一般人使用無線電的標準方式。

I like to call it the synchronous limitation.

In order to actually communicate using voiceover radio like the one I showed you, you both have to be using the radios at the same time.

實際上要用我剛才展示的無線電進行語音通訊，你們兩個都必須同時使用無線電。

If you didn't catch the message because you were distracted or you weren't at the radio, or the radio was just off, you're not going to get the message.

如果你因為分心、不在無線電旁邊，或是無線電關機而沒聽到訊息，你就收不到訊息了。

If you really needed to hear that information and it only ever happened once, and

如果你真的很需要聽到那個資訊，而且它只發生過一次，

it won't happen again unless the other person repeats it, it's lost.

而且除非對方重複，否則它不會再發生，那就沒了。

Let's move on to the privacy aspect of ham radio and gmrs.

接著我們來談談業餘無線電和 GMRS 的隱私問題。

A lot of people who are getting into comms are concerned with encryption using ham radio or gmrs.

很多剛接觸通訊的人會擔心使用業餘無線電或 GMRS 進行加密。

You cannot obscure the meaning of your messages at all.

你完全無法隱藏你訊息的意義。

For the most part, people getting into ham radio and GMRS just accept this as a limitation.

大多數剛接觸業餘無線電和 GMRS 的人，都會接受這是個限制。

It's important to remember with ham radio or GMRS anybody could be listening at any time.

使用業餘無線電或 GMRS 時，要記得任何人隨時都可能在聽。

So it's paramount that you don't share private details that you don't want somebody else to hear.

所以，絕對不要分享你不想被別人聽到的私人細節。

When you're using ham radio or gmrs, you have to give your call sign when you're transmitting.

當你使用業餘無線電或 GMRS 時，發射時必須報上你的呼號。

People can look that call sign up and figure out where you live.

別人可以查詢那個呼號，然後找出你住在哪裡。

That is another limitation that people people accept whenever they use ham radio or GM rs.

這也是大家使用業餘無線電或 GMRS 時必須接受的另一個限制。

I've given a lot of cons, but let me be really clear.

我講了很多缺點，但我要說清楚。

These radio systems are fantastic and there's a reason so many people use them.

這些無線電系統超讚的，很多人使用它們是有原因的。

They're the go to for voice transmissions.

But voice transmissions do have their limitations.

不過語音通訊確實有它的限制。

Another thing to note is that voice transmissions can only go so far.

另一點要注意的是，語音通訊的傳播距離有限。

Mostly because of the radios that you're using.

主要是因為你正在使用的那些無線電。

These handheld radios don't have a ton of power and one transmission can usually make it anywhere from 1 mile to 5 miles, depending on your location.

這些手持無線電的功率不大，一次傳輸通常可以傳到一到五英里，這取決於你的所在地。

There are repeater systems that can extend that out.

有一些中繼系統可以延長這個距離。

But generally speaking, handheld voice radios are not going to get your transmissions super far.

但一般來說，手持語音無線電的傳輸距離不會太遠。

Now let's move on to something a little bit different.

現在我們來談談一個有點不一樣的東西。

這個東西的傳輸範圍是無限的。

You could use it literally in the middle of nowhere.

你可以把它用在任何地方，真的，就算在荒郊野外也行。

You don't need cell service, you don't need WI fi.

你不需要行動網路，也不需要 Wi-Fi。

Satellite messengers are really popular for hikers, backpackers, people who go off roading in the middle of nowhere.

衛星通訊器對登山客、揹包客，還有那些在荒郊野外越野的人來說，真的超受歡迎。

They give you connectivity and peace of mind where there is no other option.

在沒有其他選擇的地方，它們能讓你保持連線，並讓你安心。

You can even go a step further and get a true satellite phone which does allow for synchronous communications.

你甚至可以更進一步，買一支真正的衛星電話，那樣就能進行同步通訊了。

But with these satellite messengers you can just message people the same way you would with your cell phone.

不過有了這些衛星通訊器，你就能像用手機一樣傳訊息給別人。

Honestly, for a lot of people, I recommend this as the first backup option to day to day communications using a cell phone.

說真的，對很多人來說，我推薦這個作為日常手機通訊的第一個備援選項。

Despite what the Internet might have you believe, not every calamity affects the entire world.

儘管網路上可能會讓你覺得不是這樣，但並非所有災難都會影響全世界。

Oftentimes emergencies that can take out your cell service or WI fi are hyper localized.

很多時候，會影響你手機訊號或 Wi-Fi 的緊急狀況，都是發生在特定區域的。

And honestly, these are the things you're way more likely to face than some worldwide catastrophe.

說真的，你遇到這些情況的機率，遠比遇到什麼世界級災難來得高。

All of that to say the things that can take out the infrastructure that allows these devices to work the way they do would be worldwide emergencies, which are very unlikely to occur.

總而言之，那些會讓這些裝置無法正常運作的基礎設施被摧毀的情況，會是世界級的緊急事件，這種情況非常不可能發生。

Most of the time, these devices are going to be perfect for backup communic communications.

大部分時候，這些裝置都能完美地作為備援通訊使用。

Even though you own the device, you don't necessarily own the transmissions.

雖然你擁有這臺裝置，但不代表你擁有它的訊號傳輸。

You're essentially renting a signal from the companies that sell these devices.

基本上，你只是在租用販售這些裝置的公司所提供的訊號。

None of them work without a subscription model.

沒有一項是不用付訂閱費就能使用的。

In order for your device to keep working, you gotta pay on time.

為了讓你的裝置能持續運作，你得準時付錢。

And if you don't, your ability to use the device gets cut off.

要是沒付，你就無法使用這臺裝置了。

It would really suck to be in an emergency where you need one of these things, but

要是你正需要這類裝置時，卻發現它因為一年前換了信用卡，或是信用卡過期了，又或是單純的帳單錯誤而無法使用，那真的會很糟。

you find out it stopped working because you changed credit cards a year ago or, or your credit card expired or there was just a billing error.

總之，一些無傷大雅的生活瑣事，就可能切斷你的緊急通訊線路。

All that to say some innocuous life occurrence could cut off your emergency communications line.

This is the problem with renting the signal.

Another thing to note is that you are relying on a company's infrastructure.

另外要注意的一點是，你得仰賴一家公司的基礎設施。

You're relying on your signal to make it to a satellite.

你得仰賴你的訊號傳送到衛星。

And that satellite has to be able to send its signal either to another satellite or the gateway on the ground that connects you with the Internet.

而那顆衛星必須能夠將訊號傳送給另一顆衛星，或是地面上的閘道，進而連接到網際網路。

If anything along that path fails, your message might not make it.

如果這條路徑上的任何環節出了問題，你的訊息可能就傳不出去。

It could be something as innocuous as a bug in the software.

這可能是個小到不行的軟體 bug。

基本上，你並不擁有這條傳輸路徑。

You just own a piece of equipment that allows you access.

你只擁有一臺讓你得以存取的設備。

And that's a stark difference from the devices I showed you earlier, like a handheld radio where you just talk into it.

這和你剛才看到的設備，像是那種你直接對著說話的手持無線電，有著天壤之別。

You own the transmissions because you own the device.

你擁有傳輸權，因為你擁有那臺設備。

Another thing to note about satellite messengers is that they can be a little bit pricey.

另外關於衛星通訊器，還有一點要注意的是，它們可能會有點貴。

They typically start around $150, and they go up from there.

它們通常從 150 美元開始，之後價格會往上加。

And you're also going to spend anywhere from $12 a month all the way up to $30 a month, depending on how many messages you want as a part of your subscription.

另外，你每個月還得花費 12 到 30 美元不等，這取決於你的訂閱方案包含多少則訊息。

As you might imagine, that can rack up over time.

你可以想像，這累積起來可是很可觀的。

If you're paying 30 bucks a month, that's $360 a year, plus the $300 you probably spent on the device.

如果你每個月付 30 美元，一年就是 360 美元，再加上你可能花了 300 美元買設備的錢。

喔，而且這還只是一臺的費用。

So if you want multiple for your entire family, it just multiplies from there.

所以如果你想讓全家人都有，那費用就會再往上翻倍。

Now, again, I really like satellite messengers, and

說真的，我非常喜歡衛星通訊器，而且

for the most part, they're one of the best, best options you can have for backup communications.

在大多數情況下，它們是備用通訊最好的選擇之一。

But that doesn't mean there aren't flaws.
