在两个Android供电设备之间传输巨大文件(例如500MB)的最快方法是什么?蓝牙? WiFi Direct?光束?或许USB On-Go?
What is the fastest way to transfer huge files (e.g. 500MB) between two android powered devices? Bluetooth? WiFi direct? Beam? or maybe USB on-the-go?
有许多变量会影响您提到的每种方法的性能。
此外,还有每个设备必须具有的必要配置和要求,以便与此工作中的解决方案。
如要求,让我们总结并比较USB之间的可能性; Wi-Fi和蓝牙:
USB性能可以极低或非常高,具体取决于可用的USB版本,这又与每个设备上的SDCard读取/写入速度相结合,允许我们准确测量并确定传输速度。
对于某些方案的USB电缆长度的物理限制也变为限制。
USB 1.0 :1.5 Mbit / s(低带宽)和12 Mbit / s(全带宽)
USB 2.0 :480 Mbit / s(有效吞吐量高达35 MB / s)
USB 3.0 :5 Gbit / s(625 MB / s)哪个与USB 2
快10倍以上
Wi-Fi丢失电缆长度等限制,但后来我们需要考虑使用的802.11协议,信号强度和范围准确测量结果:

基于每个方法的规范及其相应的版本,我的分类最快的最低点是:
There are many variables that affect the performance of each method you've mentioned.
Additionally there's also the necessary configuration and requirements that each device must have in order to have solutions like this working.
As requested, lets summarize and compare possible performances between USB; Wi-Fi and Bluetooth:
USB performance can be extremely low or very high, depending on the available USB version, which in turn, combined with the SDcard reading/writing speed on each device allows us to accurately measure and ascertain the transfer speed.
There's also the physical limitation of the USB cable length that for some scenarios becomes a limitation.
USB 1.0: 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth)
USB 2.0: 480 Mbit/s (effective throughput up to 35 MB/s)
USB 3.0: 5 Gbit/s (625 MB/s) which is more than 10 times as fast as USB 2
Wi-Fi loses limitations like cable length, but then again we need to account for the 802.11 protocol being used, the signal strength and range to accurately measure results:

More about Wi-Fi protocols from Wikipedia.
Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard that enables devices to connect easily with each other without requiring a wireless access point.
Here the communication is performed at typical Wi-Fi speeds for everything from file transfer to Internet connectivity. Essentially, Wi-Fi Direct falls under the same values presented at the Wi-Fi table (yet again keeping in mind that signal strength and range are the key factors for a good performance).
More about Wi-Fi Direct from Wikipedia.
While we need to ascertain several influencing factors to determine if Wi-Fi is faster than USB, Bluetooth is with no doubt in last place when we speak about transfer speed. Designed as a proprietary open wireless technology standard for exchanging data over short distances, the maximum speeds are below the two concurrent options:

More about Bluetooth from Wikipedia.
Being a fairly recent technology, Android Beam allows users to transfer data between devices with Near Field Communication (NFC) capabilities.
NFC is even slower than Bluetooth (both short-range communication technologies) and is limited to about 20cm of range getting up to 424 kbit/s.
On a positive note, NFC sets up more quickly than standard Bluetooth and the connection between two NFC devices is automatically established:

Based on the specifications for each method and their respective version, my classification ordered by fastest-to-lowest would be:
如果您的Android设备具有可移动SD卡插槽,则传输大文件的最快方式是将SD卡从一个设备物理移动到另一个设备。
If your android devices have removable SD card slot, the fastest way to transfer big files is to physically move the SD card from one device to another.
经过一些经验,看来三星Galaxy S4软件必须先识别文件格式,从PC转移到智能手机主存储器之前和期间。将文件移动到SD卡内存时,软件再次需要识别该文件,所以这是从文件夹中的(a)移动文件选项完成的,(b)应用程序选项移动到SD卡内存。< / p>
{对于需要在他们的三星S4上保存主内存空间的智能手机用户
After some experiences, it appears the Samsung Galaxy S4 software must recognize the file format first, before and during transfer from pc to the smartphone main memory. When moving the file to the SD Card memory, again the software needs to recognize the file, so this is done from either the (a) Move File option in the folder or, (b) Application option to Move to SD Card Memory.
{ for those smartphone users who need to save main memory space on their Samsung S4 }
对于此任务,我使用一个名为 shoutr 。正如我所能看到它正在使用内置WiFi,因此您可以获得完整的WiFi速度。
我喜欢界面;在途中与朋友分享音乐,视频和照片非常容易。
For this Task I use an app called shoutr. As I could see it is using the built in WiFi and so you get the full WiFi speed.
I like the interface; it's very easy to share music, videos and photos with friends on the way.
我在成功使用的方法是WiFi,在两个设备(发件人和接收器)上使用es文件资源管理器。我只需打开WiFi,在两个单位上,要访问我的家庭WAN,在两个设备上启动ES文件资源管理器,选择我要发送的文件/文件夹,选择"发送" 选项,并在接收设备上 - 接受,选择保存位置,按"确定" 开始接收。我从我的4岁的华为提升到我的三星Galaxy S4,在大约6分钟@〜540 kb / s中,从我的4岁的华为提出了一份200 MB的文件。
The method I've used with great success is WiFi, using ES File Explorer on both devices ( sender and receiver). I simply turn on the WiFi, on both units, to access my home WAN, start ES File Explorer on both devices, select the files/folders I want to send, choose the 'Send' option, and on the receiving device - accept, select save location, press 'OK' to start receiving. I sent a 200 MB file from my 4 year old Huawei Ascend to my Samsung Galaxy S4, in about 6 minutes @ ~540 KB/s, this way.
我正在使用徒步的messenger,这个messenger附带徒步直接功能这个功能允许分享巨大的文件。我在4分钟内分享1.2GB文件,但此功能仅适用于Windows Phone和iOS的Android设备即将推出
I'm using hike messenger this messenger come with hike direct feature this feature allow share huge files. I'm sharing 1.2GB file within 4 minutes but this feature only available for Android device coming soon for windows phone and ios
我使用跨平台 liwi app 在我的Mac和Android手机上。它还适用于Windows。它会在无论内容创建和加入过程中自动连接到WiFi上的设备。
I use cross-platform Liwi App on my Mac and Android phone. It also works on Windows. It connects devices over WiFi automatically without any create and join process.
取决于您的情况,最快的方式是通过蓝牙文件传输,或直接通过电缆。蓝牙很好,因为它是无线的,而且对于Word文档和较小的文件是相对较快的。通过电缆更适合诸如视频之类的大型文件。但是你必须携带电缆。 真的取决于情况。
Depending on your circumstances, the quickest way is either over Bluetooth file transfer, or directly through a cable. Bluetooth is nice because it is wireless and relatively quick for word documents and smaller files. Through the cable is better for large files such as video. However you have to carry a cable. Really depends on circumstances.
我使用一个名为 superbeam WiFi Direct并使您能够获得完整的WiFi速度。
I use android app called Superbeam which enables wifi direct and enables you to get full wifi speed.
如果两个设备中没有Micro SD插槽,则备用解决方案是使用任何免费云服务。您可以尝试使用Google Drive或Dropbox在同一用户名下的两个设备中安装,并尝试在介于之间同步/传输文件。
If you don't have micro SD slot in both device, the alternate solution is to use any free cloud services. You can try Google drive or Dropbox to install in both devices under same user name and try to sync/transfer files in between.
swift文件传输是比蓝牙快10倍,免费,没有麻烦!来自应用程序的描述:
swift文件传输是世界上最快的应用程序,在不使用InteNet,数据线,移动数据,Wi-Fi,NFC等的情况下使用您的朋友和家庭共享已安装的应用程序,照片,文件,文件夹和视频,高速高达8Mbps。 。现在在眨眼之间传输GB的数据。
两个,发件人和接收器,需要安装应用程序。转移然后容易:
检查PlayStore评级,它似乎与更大的文件(一个用户报告传输了整个视频集合),但似乎有MarshMoLlow(最有可能与新许可系统)有问题;两个用户报告问题访问SD卡,可以通过手动授予许可来解决)。
Swift File Transfer is 10x faster than Bluetooth, free and no hassle set up! From the app's description:
Swift File Transfer is Worldxe2x80x99s fastest app to share installed apps, photos, files, folders and videos at with high speed of upto 8mbps with your friends and family without using intenet, data cable, mobile data, Wi-Fi, nfc etc. Now transfer GB's of data in the blink of an eye.
Both, sender and receiver, need to have the app installed. Transfer then is easy:
Checking the playstore ratings, it seems to do well with bigger files (one user reports having transferred an entire video collection), but there seem to be issues with Marshmallow (most likely with the new permission system; two user report issues accessing the SD card, which might be worked around by manually granting the permission).
