'''Goals of 3GPP Long Term Evolution'''
 
===Standards===
* Download rates of 100 Mbit/s, and upload rates of 50 Mbit/s for every 20 MHz of spectrum
* At least 200 active users in every 5 MHz cell. (ie 200 active phone calls)
* Optimal cell size of 5 km, 30 km sizes with reasonable performance, and up to 100 km cell sizes supported with acceptable performance
* Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, should coverage be unavailable, continue the operation without any action on their part using GSM/GPRS or W-CDMA-based UMTS)
