<body><h1><a name="Data_Connectivity"></a>Data Connectivity</h1><h2><a name="GPRS"></a>GPRS</h2>The
General Packet Radio Service (GPRS) enables the cellphone user to stay
connected to the Internet. The data gets delivered at a rate of around
56kbits/sec in GRPS network. The technology also allows the mobile
phone users to get access to applications that were unavailable on GSM
network due to speed limitation. Blackberry emails and MMS can also be
sent through GPRS.<br><br>In GPRS, a
single piece of information is divided into small packets. If the user
is sending an e-mail, it will be divided into packets. Each packet will
take the shortest route within the network to reach the destination. <br><br>Cellphone users can email, chat, browse &amp;
stay connected over the mobile network. GPRS is a 2G technology that
does not allow video streaming, voice call etc and users will have to
move to 3G technology for using these features.<br><br>GPRS is better
&amp; cheaper than the circuit switching technology because the users
are charged only for the total amount of data, which is being
transported over the network. Whereas, in circuit switching, user has
to pay the charges even if he is in an idle state.<br><br>The speed of GPRS is determined by factors like:<br><br>a) Slots supported by the device or the base station/service provider.<br>b) Distance between the device and the base station.<br>c) Traffic on the base station.<br><br>See Also<span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;"><span class="Apple-style-span" style="color: rgb(68, 68, 68); font-family: Arial,Verdana,sans-serif; font-size: 13px; line-height: 20px; text-align: left;"><p><a href="http://www.google.com/url?q=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FGeneral_Packet_Radio_Service&amp;sa=D&amp;sntz=1&amp;usg=AFrqEzckvZlYxirempOduwF67CK7ngHFqg" style="color: rgb(0, 51, 204); text-decoration: underline;">General Packet Radio Service</a></p></span></span><h2><a name="EDGE"></a>EDGE</h2>Enhanced
GPRS (EGDE) is an advanced and faster version of GPRS. Described as a
2.75G technology, EDGE provides a data transfer speed of around
180kbits/sec, which is three times faster than GPRS. EDGE gives a
broadband-Internet like experience to the mobile device users. Because
of higher bandwidth, it provides access to applications like video
services etc. <br><br>See Also<br><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;"><span class="Apple-style-span" style="color: rgb(68, 68, 68); font-family: Calibri,sans-serif; font-size: 15px; line-height: 17px; text-align: left;"><b><br></b><a href="http://www.google.com/url?q=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FEDGE&amp;sa=D&amp;sntz=1&amp;usg=AFrqEze1nRPOhNEXV39mJkLLkAkJBgvgkQ" style="color: rgb(0, 51, 204); text-decoration: underline;">EDGE</a></span></span><h2><a name="WCDMA"></a>WCDMA</h2>Wideband
Code Division Multiple Access (WCDMA) is a third-generation (3G) mobile
wireless technology that enables the data transfer at a speed of upto
384kbits/s. WCDMA technology provides high speed Internet access and a
faster transmission of video &amp; high quality images over the network
to the mobile device users.<br><br>See Also <br><br><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;"><span class="Apple-style-span" style="color: rgb(68, 68, 68); font-family: Arial,Verdana,sans-serif; font-size: 13px; line-height: 20px; text-align: left;"><a href="http://www.google.com/url?q=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FWCDMA&amp;sa=D&amp;sntz=1&amp;usg=AFrqEzcwp477SsRH4PYIfYSBrZxcvWSf2Q" style="color: rgb(0, 51, 204); text-decoration: underline;">WCDMA</a></span></span><br><br><h2><a name="UMTS"></a>UMTS</h2>The Universal Mobile Telecommunications
System (UMTS) is a 3G network technology. It has a data transfer speed
of 384kbit/s that results in delivering faster and smoother video
streaming experience. UMTS has higher bandwidth that allows users
access services like video conferencing and IPTV on their mobile
devices.<br><br>See Also<br><br><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Times New Roman'; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; font-size: medium;"><span class="Apple-style-span" style="color: rgb(68, 68, 68); font-family: Arial,Verdana,sans-serif; font-size: 13px; line-height: 20px; text-align: left;"><a href="http://www.google.com/url?q=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FUmts&amp;sa=D&amp;sntz=1&amp;usg=AFrqEzethwLjHrUXNl2FtQTe1ZB0hBytqg" style="color: rgb(0, 51, 204); text-decoration: underline;">UMTS</a></span></span></body></html>
