| | RFC 3481 (rfc3481) - TCP over Second (2.5G) and Third (3G) Generation Wire |
 | | One important benefit for 2.5G/ 3G networks, is that it minimizes the amount of potentially stale data that may be queued in the network ("clicking from page to page" before the download of the previous page is complete). | | | TCP over 2.5G and 3G What follows is a set of recommendations for configuration parameters for protocol stacks which will be used to support TCP connections over 2.5G and 3G wireless networks. | | | While this recommendation is applicable to 3G networks, operation over 2.5G networks should exercise caution as per the recommendations in RFC 3150 [5]. |

| | Now, 2.5G (either GPRS, EDGE, or CDMA2000 technologies) is seen as a legitimate alternative to 3G. | | | With European 2.5G systems costing $3 billion compared to $250 billion for 3G, the "business case for 3G appears to be eroding," said the study. | | | At first, 2.5G was meant to be a stop-gap measure giving operators time to roll out 3G networks. |

| | 2.5G |
| | Some protocols, such as EDGE for GSM and CDMA2000 1x-RTT for CDMA, officially qualify as "3G" services (because they have a data rate of above 144 kbit/s), but are considered by most to be 2.5G services (or 2.75G which sounds even more sophisticated) because they are several times slower than "true" 3G services. | | | 2.5G is a stepping stone between 2G and 3G cellular wireless technologies. | | | While the terms "2G" and "3G" are officially defined, "2.5G" is not. |
