Conclusion

'pplication of Power Bootin& 

Power Bootin& can be ued in order to manipulate limited of power that can be ued for in&le carrier co(era&e not more t han half of capacity)



!mplementation of Power Bootin& *PB+ can be applicable for area where ite to ite ditance i more than ,-- meter for ou ter area. and can be ued alo in inner area if the morpholo&y of that area i motly dominated with Hi&h Rie Buildin&. #en e of Ru/o *Houe with Commercial area+ with more than 1 flo or. thi condition need additional ite or we can ue more pen etration power with PB implementation)
