无绳电话是固定电话的最高级产品,是一种结合了手机和固话优点于一身的产品。既有固定电话单向收费、话费便宜的优点,又可以在一定范围内移动,经济又方便,是那些追求时尚生活消费者的选择。几年前,普通用户使用的无绳电话都是模拟式的,这种电话成本较低,因此价格也比较便宜。但是模拟式无绳电话受环境影响比较大,并且容易被窃听,导致使用上的种种缺陷。因此,也就诞生了新一代无绳电话,数字无绳电话。数字式无绳电话采用2．4GHz数字传输技术,具有抗干扰能力强、保密性高等优点,但长久以来碍于价格太高,不能进入主流市场。经过多年发展,数字无绳电话的价格也逐渐下降到普通老百姓可以承受的水平。德国西门子公司和日本松下公司分别推出了400元内的数字无绳电话,以抢占低端市场。西门子公司的产品为“杰家”系列C28,松下公司是刚从500余元降价到399元的KX-TG2420CN。笔者有幸同时拿到了这两款产品,比较一下这两款的定位于主流市场的数字无绳电话究竟如何?
A cordless phone is the highest level of landline phones and is a product that combines the advantages of a cell phone with a fixed line. Both the one-way fixed-line telephone charges, telephone cheaper advantages, but also within a certain range of mobile, economical and convenient, those who pursue the lifestyle consumer choice. A few years ago, the cordless phones used by average users were all analog, and were cheaper and therefore cheaper. However, the analog cordless phones are greatly affected by the environment and are easily eavesdropped, resulting in various defects in use. Therefore, the birth of a new generation of cordless phones, digital cordless phones. Digital cordless phones using 2.4GHz digital transmission technology, with anti-interference ability, high confidentiality, but for too long because of the price is too high, can not enter the mainstream market. After years of development, the price of digital cordless phones has gradually dropped to the level that ordinary people can afford. Germany’s Siemens AG and Japan’s Matsushita Electric introduced a digital cordless phone of 400 yuan each to seize the low-end market. Siemens products for the “Jiejia” series C28, Panasonic is just down from 500 yuan to 399 yuan KX-TG2420CN. I was fortunate enough to get these two products at the same time, to compare these two models located in the mainstream market, digital cordless phone how?
