目前,新经邮电部批准入网的手持机达60多种,加上原已入网的旧机型和正在陆续申请入网的新机型,预计很快就会达到数百种。手持机不仅结构越来越小型化,而且使用时间也由开始选用了高容量的镍氢电池和锂离子电池而延长。例如,飞利浦公司推出的最新型SPARK手持机采用节能设计,使用锂电池,重仅220克,却可支持开机备用350小时,连续通话10小时以上不需充电:诺基亚公司的8100手持机也采用锂电池,待机时间达144小时,连续通话5小时以上;摩托罗拉公司的GC87数字手持机待机时间137小时,连续通
At present, there are more than 60 handsets approved by the Ministry of Posts and Telecommunications, and the old models already in use and the new models being applied for access are expected to reach hundreds quickly. Not only is the structure of the handset more and more miniaturized, but the use of time is also started by using high-capacity NiMH and Li-ion batteries. For example, the latest Philips SPARK handset with energy-saving design, the use of lithium batteries, weighs only 220 grams, but can support 350 hours standby time, continuous talk more than 10 hours without charging: Nokia’s 8100 handheld also uses lithium Battery, standby time up to 144 hours, continuous talk for more than 5 hours; Motorola’s GC87 digital handheld standby time of 137 hours, continuous
