Long r ange, portable electronic device for peer -to-peer telecommunications over longdistances.

After the name ³cell´ (the cover age/geogr aphic area) was applied to the ³cell site´ (the base station location)covered by each antenna.

Cell site is a site composed of antennatower and electronic communications

equipment placed to create a cell in cellular network for the use of mobile phones.
