手机发展简史1902年，一个叫做“内森·斯塔布菲尔德”的美国人在肯塔基州默里的乡下住宅内制成了第一个无线电话装置，这部可无线移动通讯的电话就是人类对“手机”技术最早的探索研究。

1938年，美国贝尔实验室为美国军方制成了世界上第一部“移动电话”手机1973年4月，美国著名的摩托罗拉公司工程技术员“马丁·库帕”发明世界上第一部推向民用的手机，“马丁·库帕”从此也被称为现代“手机之父”。

1G第一代手机（1G）是指模拟的移动电话，也就是在20世纪八九十年代中国香港、美国等影视作品中出现的大哥大。

最先研制出大哥大的是美国摩托罗拉公司的 Cooper博士。

由于当时的电池容量限制和模拟调制技术需要硕大的天线和集成电路的发展状况等等制约，这种手机外表四四方方，只能成为可移动算不上便携。

很多人称呼这种手机为“砖头”或是黑金刚等。

这种手机有多种制式，如NMT，AMPS，TACS，但是基本上使用频分复用方式只能进行语音通信，收讯效果不稳定，且保密性不足，无线带宽利用不充分。

此种手机类似于简单的无线电双工电台，通话是锁定在一定频率，所以使用可调频电台就可以窃听通话。

2G第二代手机（2G）也是最常见的手机。

通常这些手机使用GSM或者CDMA这些十分成熟的标准，具有稳定的通话质量和合适的待机时间。

在第二代中为了适应数据通讯的需求，一些中间标准也在手机上得到支持，例如支持彩信业务的GPRS和上网业务的WAP服务，以及各式各样的Java程序等。

3G3G，是英文3rdGeneration的缩写，指第三代移动通信技术。

相对第一代模拟制式手机（1G）和第二代GSM、CDMA等数字手机（2G），第三代手机一般地讲，是指将无线通信与国际互联网等多媒体通信结合的新一代移动通信系统。

它能够处理图像、音乐、视频流等多种媒体形式，提供包括网页浏览、电话会议、电子商务等多种信息服务。

也就是说在室内、室外和行车的环境中能够分别支持至少2Mbps（兆比特/每秒）、384kbps（千比特/每秒）以及144kbps的传输速度。

手机发展史英语作文初三英文回答：The history of mobile phones can be traced back to the early days of the 20th century, when the first attempts were made to develop wireless communication devices. In 1908, the American inventor Nathan Stubblefield invented a wireless telephone that could transmit voice over a distance of about 20 miles (32 kilometers). However, this device was not practical for commercial use, as it was too large and bulky to be portable.In the 1940s, the development of transistors led to the miniaturization of electronic devices, making it possible to develop portable wireless telephones. In 1954, the first commercial mobile phone was introduced by Motorola. This phone was called the Motorola DynaTAC 8000X, and it weighed about 2.5 pounds (1.1 kilograms). The DynaTAC 8000X was a brick-like device with a limited battery life and a range of about 30 miles (48 kilometers).In the 1980s, the development of cellular networks led to the widespread adoption of mobile phones. Cellular networks divided geographic areas into small cells, each of which was served by a base station. This allowed mobile phones to connect to the network and communicate with each other, even when they were moving.In the 1990s, the introduction of digital cellular networks led to a further improvement in mobile phone technology. Digital networks allowed for more efficient use of the available spectrum, which increased the capacity of the network and reduced the cost of calls.In the 2000s, the development of smartphones led to a revolution in mobile phone technology. Smartphones are mobile phones that are equipped with powerful processors, large displays, and a wide range of features, including internet access, email, and GPS navigation.In recent years, the development of 4G and 5G cellular networks has led to further improvements in mobile phonetechnology. 4G networks offer faster data speeds and lower latency, while 5G networks offer even faster speeds and lower latency. These advances have made it possible to use mobile phones for a wide range of applications, including video streaming, gaming, and virtual reality.中文回答：手机发展史。
