Erics son is one of the four founding members of the WAP Forum. Since 1997, when it was established, the WAP Forum has gained widespread industry support hundreds of panies are members of the worldwide WAP Forum。re sitting on a train and use this dead time to log on to your bank account, check your balance and pay a few bills all through your 3G device. You save time and can be smarter about managing your finances. ? On a touring vacation, you arrive in a new city. You haven39。s mobile works, 3G will significantly boost work capacity so operators will be able to support more users, as well as offer more sophisticated services. 3 3G At home 3G is going to affect our home and social lives in many ways. The services that 3G enables will help us to manage our personal information, simplify tasks such as grocery shopping, make better use of our time and offer services that are just fun to use. Operators will be able to develop myriad new service opportunities to attract and retain new customers. Here are some examples: ? You39。s EPOC operating system is already available and Erics son devices such as the R380 are EPOCenabled. WAP Wireless Application Protocol (WAP) is a global, open standard that gives mobile users access to Inter services through handheld devices. It enables users to easily access a whole range of Mobile Inter and other data services from mobile devices such as smart phones and municators, and without the need to plug into a separate laptop or dataenabled device. WAP enables this through a builtin WAP microbrowser that lets information be accessed direct from a phone, in the same way that web browsers provide access to online services via an Interready PC. Typically, a WAP screen will display a number of hyperlinks to various services or information portals. 8 As well as WAP phones, Erics son has also announced a WAP Service Developer39。 僅僅想像在你的行動(dòng)電話中加入照相機(jī)、攝像機(jī)、計(jì)算機(jī)、音響以及收音機(jī)功能。至今為止沒有一個(gè)人能夠完全掌握 3G的發(fā)展的進(jìn)程。 IP技術(shù)是以簡(jiǎn)單的數(shù)據(jù)包傳輸為基礎(chǔ)的 , 可以使用戶同時(shí)上網(wǎng)，但是不必花錢除了我們發(fā)送或接收數(shù)據(jù)。 3 G 在家庭中的應(yīng)用 3G將通過許多途徑影響我們的家庭和社會(huì)生活。 你可以利用乘坐火車的時(shí)間登錄你的銀行帳號(hào) , 檢查你的收支是否平衡還可以支付一些帳單 – 所有的這些都得通過 3G實(shí)現(xiàn)。 你沒必要作任何的預(yù)訂，因?yàn)槟憧梢栽诘竭_(dá)之后再做這些，通過 3G手機(jī)你能獲得最新的信息，包括旅館空缺。以下是一些例子 : 你在旅途中 ,急切地需要與在辦公 室中的同事討論草稿發(fā)表。使用 3 G 裝置 ,與他的部門連絡(luò)，下載的修理程序?qū)⑹痉朵浵髾C(jī)指導(dǎo)他修理。它在改善介紹無線通信分界面，支持多頻率通信扮演了重要的角色。 GPRS可以通過不斷增加節(jié)點(diǎn)和壓縮節(jié)點(diǎn)來實(shí)現(xiàn)數(shù)據(jù)包在移動(dòng)終端和網(wǎng)關(guān)中的傳輸。 可以在瞬間建立連接 WCDMA 寬帶碼分多址接入技術(shù) (WCDMA) 提供的數(shù)據(jù)傳送速率遠(yuǎn)遠(yuǎn)大于現(xiàn)在我們采用的通信方式 ,提供高達(dá) 2Mbit/s的傳輸速率 , 大大提 高了光纖對(duì)語音信號(hào)的傳輸率。 愛立信在 WCDMA的研發(fā)方面走在了前列。 11 cdma2020 cdma2020對(duì)于提高寬帶傳輸速率和遞送高質(zhì)量的語音服務(wù)無疑是 3G標(biāo)準(zhǔn)最有效率的。 cdma2020完全融合了 IMT2020標(biāo)準(zhǔn)，并且滿足了 3G的標(biāo)準(zhǔn)。 藍(lán)牙 藍(lán)牙是在不同的裝置之間進(jìn)行雙通道短波傳輸?shù)墓_標(biāo)準(zhǔn)。藍(lán)牙將成為通信領(lǐng)域中用于不同設(shè)備之間傳輸數(shù)據(jù)最重要的手段，同時(shí)它也將成為發(fā)展最快的發(fā)展領(lǐng)域。 藍(lán)牙是由愛立信公司首先研制的 ,但現(xiàn)在藍(lán)牙主要是由一個(gè)特殊的世界組織來主管。 Symbion的目標(biāo)是通過以下兩種方式提高其在移動(dòng)通信市場(chǎng)的份額 : 典型地，無線傳輸通訊協(xié)定監(jiān)控屏將會(huì)顯示各種不同的服務(wù)或數(shù)據(jù)入口的若干超鏈接。 自從 1997 以后，當(dāng)它成立的時(shí)候 , 無線傳輸通訊協(xié)定論壇已經(jīng)得到廣泛的工業(yè)廠商的支持，他們大部分都是是世界無線傳輸通訊協(xié)定論壇的成員。
