'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)
