[ISOC_KE] 4G vs LTE

Good afternoon to you all, I must say in deed great speeches today during the ground breaking ceremony for konza city , however i did do hear the minister for information refer to where we are heading into the 4G (fourth generation networks)network as LTE (long term evolution network) is this the case ? I do not bring this up because the minister mentioned it but the main reason is we need to get some things clear as we move on, in some regions like in the wide Asian continent the likes of such technologies as WIMAX is also being referred to as 4G. Is wimax the next generation ? any white papers on the LTE & 4G comparisons ? as always lets keep it alive , the topic Regards, kelvin
