   Hi badgolferman,   
      
   You're not an apologist so an actual adult conversation can be had with you,   
   where people discuss openly what they think and what they need to know.   
      
   While Joerg Lorenz is a moron not worth discussing further, I think Alan   
   Browne brought up an excellent point about asymmetries in speedtest results.   
      
   The high transmitting power of the cellular tower ties with the (presumed)   
   decent receiver sensitivity of the cellphone in the outbound direction.   
      
   But in the inbound direction, the puny transmitting power of the cellphone   
   has to tie in with the (presumed) excellent tower receiver sensitivity.   
      
   What would be interesting is to list those four typical values:   
   a. What is the typical transmit power of a typical cellphone tower?   
   b. What is the typical receiver sensitivity of that typical cellphone tower?   
   c. What is the typical transmit power of a typical cellphone?   
   d. What is the typical receiver sensitivity of that typical cellphone?   
   (Other things matter, like SNR, but those seem to be the most important.)   
      
   Without those four numbers, we really can't talk about what the speeds   
   should be in both directions.   
      
   I wonder if the moron Joerg Lorenz can supply us with those accurate values?
