Tracking your every move

Some families in America and elsewhere have started buying child?friendly mobile phones outfitted with GPS (Global Positioning System) technology.

These phones and their related tracking services allow parents to pinpoint the location of their children with ease. Parents agree to pick up the phone bill in return for the reassurance of knowing where their children are; children are prepared to put up with the snooping if they are allowed to have a phone.

Mobile operators in America are now launching tracking services. Under a federal mandate known as E911, they had to upgrade their networks to ensure that anyone dialling the 911 emergency number could be located to within 100 metres. Some operators opted for triangulation technology, which determines the location of the handset by comparing the signals received by different base?stations. But Verizon and Sprint chose to adopt the more expensive but more accurate GPS technology instead, and are now looking for ways to make money from it.

Verizon calls its serviceChaperone”. For $10 a month, parents can call up the location of their childs LG Migo handset from their own mobile phones, or from a PC. The child receives a message saying that the handsets position has been requested, and the parents receive an address, or a marker on a web?based ap, giving the childs location. For an extra $10 per month, they can sign up for Child Zone, a service that, among other things, fires off an alert when a youngster (or, at least, the youngsters handset) trays outside a specified area.

For its part, Sprint has launched a similar service that can also let parents know when a child arrives at a particular location.

Another location service is available from Nextel, a mobile operator that was taken over by Sprint in 2005. Nextel opened up some of its systems to enable other firms to build their own software and services on top of its GPS technology. One example is AccuTracking, a small company which offers a tracking service for $6 a month and boasts that it isideal for vehicle trackingor to keepvirtual eyes on kids”. Some customers are also using the service to track their spouses, by hiding phones in their cars.“Mine is hidden under the hood, hot-wired to the batteryit works very well and it is easy to hook up continuous power,” writes one customer on AccuTrackings message board, who is tracking her husband.

Start-ups are working on everything from city-wide games of hide-and-seek to monitoring the locations of Alzheimers patients. Services that monitor jogging routes, and work out distance travelled and calories consumed, might also prove popular.

As a result, mobile operators, handset-makers and start-ups could transform and expand a small, specialist market hitherto dominated by expensive, dedicated tracking systems.





美国的移动电话运营商们正在推出追踪服务。遵照一条叫做E911的联邦法令,他们要升级服务网络,确保能找到任何拨打911呼救电话的人所处的位置,误差不超过100米。一些运营商采用了三角定位技术,此技术通过比较不同基站接收的手机信号来确定手机所处的位置。VerizonSprint 两个运营商则选用了更昂贵、但更精确的GPS技术,现在正在此基础上推出新服务,希望能以此赚钱。

Verizon 把它的服务叫做“陪护者”。每月花上10美元,父母用手机或个人电脑发出一个要求,就可以知道他们孩子的LG Migo手机的位置。孩子会收到一条“该手机的位置被要求发送”的信息,父母则收到一个地址,或是网络地图上的一个标记,指示出孩子的位置。如果每月多付10美元,父母就可以成为一个叫“孩子地带”的用户,如果一个年轻人(或至少是这年轻人的手机)在一个特定的区域外游荡时,该服务就会立刻发出警告给父母,类似的服务还有一些。


2005年被Sprint兼并的Nextel 则有另一项定位服务。Nextel开放了它的部分系统,可以让其他公司在其GPS技术平台上建立自己的软件与服务。Accu寻踪公司就是一个范例,这家小公司提供的追踪服务每月收费6美元,号称是“理想的车辆追踪工具”,还可以“时刻盯着孩子”。有些客户把电话藏在配偶的车里,用Accu寻踪公司的服务追踪他们。该公司的一个顾客在公司网站的留言版写道:“我把电话藏在引擎盖下边,并插在汽车电池上——真的很管用,而且挂接不间断电源也很容易。”这位女士是在追踪她的丈夫。
