falls below the threshold, say 5 dB, network fails to
operate. Is it easy to influence the SNIR? Yes, it is,
with a jammer--an easy-to-transport device that
transmits a jamming signal within a targeted
bandwidth. A jammer can influence the network
operability with no damage of the physical infrastructure. Hence, it is necessary to protect the
network against jamming, for example, by using
the direct sequence spread spectrum (DS-SS)
technique. Protection of a transmitted signal with
data throughput of 1 Gbit/s, using modest DS-SS
signal processing gain of 20 dB, requires a bandwidth of 100 GHz, which cannot be provided by a
5G network. It is not hard to imagine what few jammers strategically positioned near a crossroad
may do to a car-to-car communication at this stage
of technological maturity.
Technology--such an impressive term that
raises so many questions on so many levels. But
this time we will ask just one. Do we understand
the full impact of merits and controversies of
technology? A wise man said: "There is no such
thing as a good knife or a bad knife. Just the purpose that man has given to it--as a weapon or a
useful tool."
