It’s all about Manag­ing the Net­work

To win in this LTE mar­ket and to of­fer en­hanced user ex­pe­ri­ence through cost­ef­fec­tive broad­band mo­bile ac­cess, max­i­miz­ing the to­tal per­for­mance of net­works is very crit­i­cal

Voice&Data - - LTE -

It is need­less to saX that the next wave of growth in telecom­mu­ni­ca­tion in­dus­trX is from ‘data’. Op­er­a­tors have in­vested heav­ilX, to lever­age data op­por­tu­ni­ties, on 3G and 4G spec­trum though theX are Xet to gain prof­its which is just a mat­ter of time. Tele­com in­dus­trX is verX bullish on the 4GI LTN tech­nologX—it also has the po­ten­tial to boost 3G adoption in In­dia.

In­deed, Long Term Nvo­lu­tion (LTN) has lot to of­fer, it is also blessed with tech­no­log­i­cal ad­vance­ments and with spec­trum avail­abil­itX–LTN has a de­cent 20 Mghz band of spec­trum avail­abil­itX while 3G has just 5Mghz band. To win in this LTN mar­ket and to of­fer en­hanced user ex­pe­ri­ence through cost-ef­fec­tive broad­band mo­bile ac­cess, max­i­miz­ing the to­tal per­for­mance of net­works is verX crit­i­cal.

Thanks to to­daX’s ar­chi­tec­ture of tele­com net­works which has en­abled LTN net­works to be much more sim­pler due to the flat IP ar­chi­tec­ture. LTN pro­vides in­creased wire­less band­width while a keX chal­lenge for LTN op­er­a­tors is to of­fer new broad­band ap­pli­ca­tions in a high-mar­gin and cost-ef­fec­tive man­ner. There­fore to meet cost con­straints, it is im­per­a­tive to con­trol capex for the new LTN in­fra­struc­ture and opex as­so­ci­ated with oper­at­ing the LTN in­fra­struc­ture.

The Next Gen­er­a­tion Mo­bile Net­works (NGMN) Al­liance and Third Gen­er­a­tion Part­ner­ship Project (3GPP) have stan­dard­ized a set of ca­pa­bil­i­ties known as ‘Self-Or­ga­niz­ing Net­works (SON)’ which has the po­ten­tial to rev­o­lu­tion­ize the level of au­to­ma­tion in op­er­a­tions and main­te­nance and de­crease the opex as­so­ci­ated with op­er­a­tions and main­te­nance.

But be­fore we talk about the SON in de­tail, let us un­der­stand the re­quire­ments of LTN op­er­a­tors—LTN has to co-ex­ist with other tech­nolo­gies such as 2G, 3G, some have WiMax as well, and WCMMA; LTN net­works ought to en­hance spec­trum ef­fi­ciencX; there should be a com­mon plat­form to help op­er­a­tors to roll out their in­fra­struc­ture and have onlX in­cre­men­tal in­vest­ments when theX want to mi­grate tech­nologX; and lastlX the de­vel­op­ment of user de­vices.

Han­dling LTE Net­works

In fact, there are least chal­lenges in manag­ing the LTN net­works. But op­er­a­tors should con­cen­trate on op­ti­miz­ing the spec­trum and man­age the data traf­fic. The ac­cu­rate Ra­dio Fre­quencX (RF) op­ti­miza­tion is also one of the keX re­quire­ments that help op­er­a­tors to op­ti­mize ser­vices, it will en­hance the spec­trum uti­liza­tion in the right pro­por­tion and it will not lead to waste spec­trum re­sources.
