看到《数字通信》的征文启事很是兴奋,我先后购买并使用了11款手机,第9、10、11款为GSM制式智能手机,型号分别是Motorola m388、Dmod 535、Motorola A780。智能手机,我比较赞同“掌上电脑+手机=智能手机”。从广义上说,智能手机除了具备手机的通话功能外,还具备了PDA的大部分功能,特别是个人信息管理以及基于无线数据通信的浏览器和电子邮件功能,并装有为满足通讯及PDA应用而设计的操作系统。
I was very excited to see the essay on “Digital Communications”. I purchased and used 11 mobile phones successively. The 9th, 10th and 11th models are GSM smartphones. The models are Motorola m388, Dmod 535 and Motorola A780 respectively. Smartphone, I prefer “Pocket PC + phone = smart phone”. Broadly speaking, in addition to the smart phone has the phone call features, but also has most of the PDA features, especially personal information management and wireless data communications based browser and e-mail capabilities, and equipped with communications and PDA Application and design of the operating system.
