GSM, CDMA, Wi-Fi, WiMax: Can't we all just get along? With IMS (IP Multimedia Subsystem), we just might. Now in trials, IMS network technology will allow any type of packet data--voice calls, video, music, HTML, you name it--to move seamlessly between IMS-enabled networks. With IMS, you'll be able to start a call on your cell phone and end it on a VoIP landline, watch pay TV on either a handset or a big screen (smart-card technology identifies you), and access your contacts from any connected PC or handset. But the benefits will kick in only once IMS is widely deployed, which will take several years.
