The FCC and their counterparts outside of the U.S. have set aside
bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band.
Spectrum in the vicinity of 2.4GHz, in particular, is being made available worldwide.

―
A unit of data routed between an origin and a destination in a network.

Physical layer convergence protocol
Preamble Type
―
During transmission, the PSDU shall be appended to a PLCP
preamble and header to create the PPDU. Two different preambles and headers are
defined as the mandatory supported long preamble and header which interoperates
with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std
ocessed to aid in demodulation and delivery of the PSDU.
The optional short preamble and header is intended for application where maximum
throughput is desired and interoperability with legacy and non-short-preamble
