英国一家公司研制成功一种既可用作固定电话,又可用作移动电话的两用话机。 这种两用电话机,在住宅内使用时,相当于一部普通的无绳电话。离开住宅后,两用电话机便与移动通信网自动接通,成为一部移动电话。 A British company successfully developed a dual-use phone that can be used both as a fixed phone and as a mobile phone. This dual-use phone, when used in a home, is equivalent to an ordinary cordless phone. After leaving the residence, the dual-use telephone automatically connects with the mobile communication network to become a mobile phone.
