Packet Error
Rate (PER)
Uplink
Percent
(%)
Each transport block
carrying one or more
packets has a
retransmission (HARQ)
mechanism,
After the maximum
number of retransmission
s
is exceeded, the packet is
considered as a packet
with errors.
Number of UL
packet e
rrors /
total number of
bursts within
the sampling
period
Can be used to
explore (TCP)
throughput
degradation issues
(if the PER ratio is
high).

Downlink –
With MIMO
bps
This report presents the
actual transferred bits per
DL
MCS for MIMO within
the sampling period.
Bits / second
per DL MCS
(Modulation)
BreezeCOMPACT
Rate Adaptation
selects the MCS
(modulation) to be
used in the DL and
UL. T
he throughput
is maximized
according to various
considerations,
such
as the channel
condition of the
UEs.
The report may help
to understand issues
related to
low-modulation
CPEs, in order to
improve deployment
spectral efficiency.

MCS
Distribution
Downlink –
Without
MIMO
bps
This report presents the
actual transferred bits per
DL MCS without MIMO
within the sampling
period.
Bits / second
per DL MCS
(Modulation)
The report may help
to understand issues
related to
low-modulation
CPEs, in order to
improve deployment
spectral efficiency.

This report presents the
actual transferred bits per
