'pplication of Power Bootin&
Power Bootin& can be ued in order to manipulate limited of
power that can be ued for in&le carrier co(era&e not more t
han half of capacity) !mplementation of Power Bootin& *PB+ can be applicable for
area where ite to ite ditance i more than ,-- meter for ou
ter area. and can be ued alo in inner area if the morpholo&y
of that area i motly dominated with Hi&h Rie Buildin&. #en
e of Ru/o *Houe with Commercial area+ with more than 1 flo
or. thi condition need additional ite or we can ue more pen
etration power with PB implementation)
