一种使用蜂窝网络的便携式电话。

手机

移动电话是一种使用蜂窝网络的便携式电话。它通过无线电波连接到基站,只要有信号覆盖,它就能工作。它可以拨打电话、发送短信和访问互联网。它集电话、相机、GPS、钱包和电脑于一体。第一个移动电话通话是由摩托罗拉公司的马丁·库珀于1973年拨出的。

早期的手机就像砖头一样笨重,重达一公斤多,售价数千元。它们是模拟信号,电池续航能力也很差。数字网络改善了语音质量,并增加了短信功能。智能手机则加入了应用程序、触摸屏和高速数据传输。手机逐渐发展成为一个平台。

移动电话的几代

手机改变了社会。它连接了数十亿人,促进了商业、教育和应急响应。但同时,它也分散注意力、追踪用户、造成孤立。手机功能强大,但其带来的后果却喜忧参半。它是迄今为止最个人化的科技产品。

    It's funny how we went from these being a luxury to something everyone has. My kids don't even know what a landline is.

    The term mobile phone feels a bit dated now. Most people just say phone and assume you mean the mobile one.

    I remember my first mobile phone was the size of a brick. Now mine is thinner than a pencil. Technology moves fast.

    Interesting that the definition focuses on the technical aspect. The social impact of mobile phones is probably a bigger topic.
