Comments on: When mobile providers upgrade their system from 2G to 3G, is it on the same equipment or do the install new? http://4gnetwork.us/2g-network/when-mobile-providers-upgrade-their-system-from-2g-to-3g-is-it-on-the-same-equipment-or-do-the-install-new Thu, 18 Feb 2010 12:40:59 -0600 http://wordpress.org/?v=abc hourly 1 By: nightlisa2 http://4gnetwork.us/2g-network/when-mobile-providers-upgrade-their-system-from-2g-to-3g-is-it-on-the-same-equipment-or-do-the-install-new/comment-page-1#comment-392 nightlisa2 Thu, 05 Nov 2009 22:42:59 +0000 http://4gnetwork.us/2g-network/when-mobile-providers-upgrade-their-system-from-2g-to-3g-is-it-on-the-same-equipment-or-do-the-install-new#comment-392 Typically they phase out the older equipment and install new. 2G was very slow in accommodating the data packets that people are starting to use more common place today. 2G uses mostly TDMA or CDMA networks, which originally was an improvement from analog to digital signal, but 3G works better with GSM networks, and GPRS requirements. Some companies like AT&T/Cingular kept both equipment installed 2G & 3G. But when new towers went in, only 3G/GSM towers were going up. All the TDMA towers were left in place, but eventually people carrying TDMA cell phones, noticed their signal strength was not near what someone else carrying a GSM phone would receive. And then as phones broke down or upgrade new contracts went into effect, the only new equipment you could buy was GSM.<br><b>References : </b><br> Typically they phase out the older equipment and install new. 2G was very slow in accommodating the data packets that people are starting to use more common place today.
