自從模擬蜂窩式服務(wù)逐漸淡出市場(chǎng)，數(shù)字化服務(wù)的日益深入，美國聯(lián)邦通信委員會(huì)（FCC）于2002年接受的委托宣布所有的執(zhí)行者應(yīng)于2008年2月18日結(jié)束其模擬服務(wù)。 AT&T, Verizon Wireless和Alltel三家公司將關(guān)掉他們的模擬網(wǎng)絡(luò)服務(wù)生產(chǎn)線，但是此項(xiàng)服務(wù)一旦停止，將會(huì)影響更多與模擬服務(wù)相關(guān)的服務(wù)，而不僅僅是模擬手機(jī)（大哥大），美聯(lián)社預(yù)測(cè)，持猶豫態(tài)度的用戶近1百萬。 據(jù)美聯(lián)社一些burgular警告顯示，車內(nèi)反映系統(tǒng)和自動(dòng)化測(cè)量系統(tǒng)可能會(huì)受此影響。 警告顯示，模擬網(wǎng)絡(luò)作為主要的或是后備鏈接，可能會(huì)丟失他們與報(bào)警中心的聯(lián)系。尤其是家用的應(yīng)用模擬無線服務(wù)的無線電話。 舊一代的安裝OnStar （GM）的汽車，如TeleAid （Mercedes-Benz）和Lexus Link，他們的一些服務(wù)也可能會(huì)受到影響。由這些生產(chǎn)廠家在2003年生產(chǎn)的型號(hào)和以前的未升級(jí)的型號(hào)都會(huì)受到影響，2004和2005年生產(chǎn)的需接受OnStar的更新。 最終，自動(dòng)化電量讀卡器和卡車快速跟蹤設(shè)備都需要更新。 [FONT=times] original text [/FONT] [font=times][Color=#708090]Since analog cellular service has been dying for years as digital service becomes pervasive, the Federal Communications Commission mandated in 2002 that all carriers should cut their analog service on Feb. 18, 2008. AT&T, Verizon Wireless, and Alltel will be turning off their analog networks for good. But the service shutdown affects more than just those with analog cellphones （which, the Associated Press estimates, stands at about 1 million users）. Some burgular alarms, in-car response systems, and automated metering systems can be affected, according to the Associated Press. Alarms that use the analog network as a main or backup link may lose their connection to alarm centers. Typically, homes with no wired phone service use analog wireless service. Older cars equipped with OnStar （GM）, TeleAid （Mercedes-Benz） and Lexus Link may lose service as well. Cars from these manufacturers from the 2003 model year and older won‘t be upgradable, but 2004 and 2005 models will be able to receive OnStar upgrades. Finally, automated electricity meter readers and truck fleet tracking devices will need to be upgraded. [/color][/font]
