在不使用蜂窝塔的情况下在两个智能手机之间进行通信-点对点 [英] Communicating between two smartphones without using a Cellular Tower - Peer to Peer
问题描述
让我们说我有两部彼此相距50米的手机，我想在不使用任何通信到蜂窝塔的情况下，将很小的数据包从移动设备A发送到移动设备B.
Lets say I have 2 mobile phones which are 50 meters away from each other and I would like to send a very small packet of data from mobile-A to mobile-B, without using any communication to cellular tower.
为简化起见，我想构建一个应用程序，该应用程序为相同半径(在同一区域内)的2个移动电话实现对等连接.
To make it simpler, I would like to build an app which implements a Peer to Peer connection for 2 mobiles in the same radius (in the same area).
这些天使用智能手机技术是否可行? (例如Android)
Is this feasible using the technology of smartphones these days? (Android for example)
推荐答案
否.移动网络获得许可的无线电服务因国家/地区而异，但据我所知，其中没有一种允许这种即席通信.
No. The radio services the mobile networks are licensed under vary by country, but none that I know of allows for that kind of ad-hoc communication.
50米对于Wi-Fi来说是一个延伸，尤其是在天线不理想的手机中.蓝牙也可以.
50 meters would be a stretch for WiFi, especially in a pair of handsets with less-than-ideal antennas. Bluetooth would also be right out.
