VoIP31網友評論:*最近很紅的一個對談軟體Skype(繁體中文語言包)用了P2P技術,過防火牆後還是超級清楚,美東與台灣連線時對方說話就像坐在正對面一樣,讓我徹底對網路語音軟體改觀,想想以前用yahoomessenger或MSN那種模糊延遲的語音真是好笑.然後因為它免費又太清楚,介紹親友後我已經很久沒花錢打國際電話了.*清晰度一級棒，即時通和MSN根本無法比啊！

並且即時通和MSN都只能單向發話，而SKYPE完全跟電話一模一樣！

目前試用過：台灣→台灣、大陸、加拿大、東京超清晰，完全沒有延遲的狀況！

使用藍芽耳機，爽度更是百分之兩百啊*我有一個朋友的公司與外國的sales已經完全改用skype.一個月省了數十萬元的國際電話費。*今天試玩4人confrence，XX當host，效果實在是太驚人了!不止是每個人音質都很讚而且都沒有delay的感覺!!真的是推薦給大家用!!節錄自E天下6月號VoIP網友評論:節錄自E天下6月號VoIP32演讲完毕，谢谢观看！演讲完毕，谢谢观看！333G行動通訊與VoIP網際電話之企業應用與發展3G行動通訊與VoIP網際電話之企業應用與發展34ContentIntroductiontoTelecommunications3GLicensesAuctionUMTSWCDMAWirelessApplicationsVoIP&itsImplementationConclusionsContentIntroductiontoTelecom35CellularPhoneGenerations1G:AMPS(AdvancedMobilePhoneSystem)=>analogsystem2G:GSM(GlobalSystemforMobilecommunication)=>digitalsystem2.5G:GPRS(GeneralPacketRadioSystem)3G:IMT-2000(InternationalMobileTelecommunicationforyears2000)CellularPhoneGenerations1G:36DigitalServicesVision032649.61281443842,0001G2G3GVoiceTextMessagingVideoStreamingStillImagingAudioStreamingDataTransmissionSpeed-kbpsElectronicNewspaperRemoteMedicalService(Medicalimage)VideoConference(Highquality)Telephone(Voice)VoiceMailE-MailFaxElectronicPublishingVideoonDemand:Sports,NewsWeather
