20世纪90年代末期,半小时电表(每半个小时收集一次电表数据)市场已解除监管,静止式读表方式的转变全面展开。每天远程读表的需求使人们需要寻找一种能够替代公共交换电话网(PSTN),并且有成本效益的方法。然而在很多地方,重新安装部署一个硬连线解决方案的成本可能高达数千英镑,甚至有些地方布线是完全不现实的。随着技术的发展和成本模型的改进,在众多的可选择方案中,全球移动通信系统(GSM)成为最流行的、并且最终超过PSTN成为人们的第一选择。后来,GSM也被其他市场用来传
In the late 1990s, the half-hour meter (which collects meter data every half hour) has been deregulated and the transition to static meter reading has begun. The need for remote meter reading every day necessitates the search for a cost-effective alternative to the public switched telephone network (PSTN). However, in many places, the cost of reinstalling a hardwired solution can cost as much as several thousand pounds, and even in some places routing is completely impractical. As technology advances and cost models improve, the Global System for Mobile communications (GSM) becomes the most popular among numerous alternatives and eventually surpasses PSTN as the number one choice. Later, GSM is also used by other markets
