Mobile Broadband Explained What is Mobile Broadband Technology? Mobile broadband technology can be a confusing concept to grasp – It works like the internet, but it operates the same way a cell phone does. And there are different kinds of the technology, different networks and lots of providers to sort through. Below you’ll find some of the basics on mobile broadband for those less technically inclined folk. Since nowadays the internet is a necessity, not a luxury, people are finding that they want to have access to it everywhere and anytime. Enter broadband mobile technology – Internet that can be accessed literally anywhere you can get a cell phone signal, inside or outside. Mobile broadband operates on the same technology that cell phones do, this means that through radio waves and frequencies, packets of information are sent back and forth. In terms of a phone call, the packet would be voice information however for mobile broadband the packets are all data in the form of things like email and web pages. There are two kinds of technologies that mobile devices currently use: Code Division Multiple Access (CDMA) and Global System for Mobile Communications (GSM). Mobile broadband operates on a third-generation of this technology which is why it is called 3G. The CDMA version of mobile broadband is called EV-DO ((Evolution-Data Optimized or Evolution-Data Only). This technology runs on the part of the cell network that is used for data. But because EV-DO requires that you separate the data information from the voice information, you can’t actually talk on the phone while at the same time surfing the internet. On the other hand the GSM technology, called HSDPA (High-Speed Downlink Packet Access), can handle both data and voice information at the same time. Both types of technology require that you have some kind of hardware set up in your device or computer to access the network (like a network card) and both run at varying speeds (between 300-700 Kbps). GSM is very popular in Europe while CDMA is more popular in North America.

Leathanbhanda Soghluaiste Míniú Cad é Teicneolaíocht Leathanbhanda Mobile? Is féidir a bheith teicneolaíocht leathanbhanda soghluaiste coincheap mearbhall a thuiscint - Oibríonn sé cosúil leis an idirlíon, ach oibríonn sé ar an mbealach céanna a dhéanann le fón póca. Agus tá cineálacha éagsúla de ar an teicneolaíocht, líonraí éagsúla agus go leor de na soláthróirí a shórtáil tríd. Anseo thíos gheobhaidh tú roinnt de na bunghnéithe ar leathanbhanda soghluaiste do na tíre níos lú go teicniúil claonta. Ós rud é go lá atá inniu ann ar an idirlíon ní gá, le só, tá daoine a aimsiú gur mian leo rochtain a fháil ar sé i ngach áit agus ag am ar bith. Cuir isteach an teicneolaíocht leathanbhanda soghluaiste - Idirlíon ar féidir iad a rochtain literally in áit ar bith is féidir leat a fháil cille fón comhartha, laistigh nó lasmuigh de. Oibríonn leathanbhanda soghluaiste ar an teicneolaíocht céanna a dhéanamh teileafóin phóca, ciallaíonn sé seo go bhfuil trí tonnta raidió agus na minicíochtaí, paicéid na faisnéise a chuirtear ar ais agus amach. I dtéarmaí glao gutháin, bheadh an phacáid faisnéis a guth, áfach, do leathanbhanda soghluaiste na paicéid bhfuil na sonraí go léir i bhfoirm rudaí ar nós r-phost, agus leathanaigh ghréasáin. Tá dhá chineál de theicneolaíochtaí go gléasanna soghluaiste a úsáid faoi láthair: Rochtain Rannán Cód Il (CDMA) agus Córas Domhanda do Chumarsáid Soghluaiste (GSM). Oibríonn leathanbhanda soghluaiste ar an tríú glúin na teicneolaíochta seo agus sin an fáth go bhfuil sé ar a dtugtar 3G. Tá an leagan CDMA leathanbhanda soghluaiste a dtugtar EV-NÁ ((Evolution-Sonraí Optamaithe nó Evolution-Sonraí Amháin). Ritheann an teicneolaíocht ar an chuid den líonra cille a úsáidtear le haghaidh sonraí. Ach mar gheall ar Éilíonn EV-DO gur scaradh leat an eolas ó shonraí an t-eolas guth, ní féidir leat labhairt iarbhír ar an teileafón agus ag an am céanna ag scimeáil ar an idirlíon. Ar an láimh eile, is féidir an teicneolaíocht GSM, ar a dtugtar HSDPA (Ard-Gaoithe Rochtain Paicéad Downlink), láimhseáil an dá sonraí agus gutha eolas ag an am céanna. A cheangal ar an dá chineál teicneolaíochta go bhfuil tú de shaghas éigin crua-earraí ar bun i do gléas nó ríomhaire chun rochtain a fháil ar an líonra (cosúil le cárta líonra) agus an dá rith ag luas éagsúla (idir 300-700 Kbps). GSM Tá an-tóir san Eoraip agus tá CDMA níos mó tóir i Meiriceá Thuaidh.
