Hi Nathan,

The trunking between EPC and Compacts is licensed 2+0 in and out at most 
locations with 10 gig uplinks that tie the microwave networks into the fiber 
network.  Latency is approx 1 ms from ENB to EPC.  We are using 
Sub frame 1/1 and do not use the EPC for queuing.  We set each UE to max and 
traffic shape the customer at the router.  We have had over a 100 UEs on an eNB 
and still had great performance with plans ranging from 3-20 Mbps.  I'm just 
noticing slower speedtest on web based tests vs iperf.  Like I said it's not 
causing performance issues just proof to customer issues.  People will just 
call because they get 7 Mbps not 10 Mbps.  If you fire up multiple movie 
streams then their service plan will show its reaching its set data rate.
