mobile communication technology

Mobile Communication Technology NO 39 Zhang Jiwang With the development of mobile communication technology the life of people more and more inseparable from the mobile communication technology The development of mobile communication technology is very fast from the first generation to the development to the present only the fourth generation of about 30 years Only voice calls from the first generation of mobile communication technology the development to the second generation of mobile communication technology can send text messages and voice calls use for 12 years To the third generation mobile communication technology and development On the front and on the basis of increased access to the Internet only for 16 years And are now vigorously the construction of the fourth generation mobile communication technology more is developing rapidly In other words people now can t keep up with the speed of the mobile communication technology development The first generation of mobile communication techology Only for voice calls So is not the best method for some occasions such as at the meeting or a night rest and so on And for some body disabled people only voice calls is obviously not enough so there will be a second generation of mobile communication technology The second generation of mobile communication technology Here to join the function of sending text messages you have sent a message around the world each year And the number every year in growth With the development of the Internet if the phone is just send information and phone might have been unable to meet the needs of contemporary people So there will be a third generation mobile communication technology Third Generation Mobile Telephony Here to further strengthen the efficiency of mobile Internet access People can follow one s inclinations of surfing on the Internet anytime and anywhere it also changed the development history of the Internet Put the mobile Internet on the forefront of the trend But with the development of mobile Internet people s desire will be limited to the third generation mobile communication technology of the Internet speed People want faster and more stable access to the Internet speed And the fourth generation mobile communication technology The fourth generation mobile communication technology More than 2 m s with asymmetric data transmission capacity It includes fixed broadband wireless access broadband wireless local area network LAN as the three generations that the function No matter what generation mobile communication technology development to or how quickly the development of mobile communication technology but cannot leave the people s life Human life is the beacon in the development of mobile communication so I think the mobile technology always makes people s life is getting better and better Key words first generation second generation third generation fourth generation voice call text message internet access faster and more stable 随着移动通信技术的发展 人们的生活越来越离不开移动通信技术 移动通信技术的 发展是十分迅速的 从第一代到发展到现在的第四代仅仅用了约 30 年 从第一代移动通信 技术只能进行语音通话 发展到第二代移动通信技术可以发送文本信息和语音通话 用了 12 年 又发展到第三代移动通信技术 在前面的基础上又增加了互联网的接入 仅仅用了 16 年 而现在正在大力建设的第四代移动通信技术 更加是发展迅速 换句话说 人们现 在已经跟不上移动通信技术发展的速度了 第一代移动通信技术 只能进行语音通话 所以对于一些场合来说并不是最好的方法 例如 开会的时候 或者是晚上休息的时候等等 还有对于一些身体有障碍的人们只能进行语音通话时显然不 够的 所以就有了第二代移动通信技术 第二代移动通信技术 这里加入了文本信息发送的功能 接下来就有了每年发送了 条信息在全世界 而且这 个数字每年都在增长之中 随着互联网的发展 如果手机仅仅是发信息和打电话可能已经 无法满足当代人们的需求了 所以就有了第三代移动通信技术 第三代移动通信技术 这里进一步强化了手机接入互联网的效率 人们可以随时随地随心所欲的进行网上冲 浪 这也改变了互联网的发展历史 让移动互联网走上了潮流的前沿 但是随着移动互联 网的发展 人们的欲望将不仅仅局限于第三代移动通信技术
