These data are aggregated statistics on data measured in Navacchio at
the beginning of 2006 using two laptops in 802.11 ad hoc mode at
different distances on a wide uncultivated field.

See README int he parent directory for a description of the measured
data.

Each file contains data relative to a single transmission speed: 1, 2,
5.5, 11 Mb/s.  Each line contains these fields:
 - sequence number starting from 0 relative to a ~15min measurement
 - lenght of the frame in bytes: to obtain the whole frame lenght one
   must add an LLC/SNAP header, CRC and MAC header.  There are three
   lengths: 500, 1000 and 1500 bytes.  The frame lengths in ms are:
		+-------+-------+-------+-------+-------+
		|len[ms]| 1 Mb/s| 2 Mb/s|5.5Mb/s|11 Mb/s|
