Un­leash­ing the Po­ten­tial

The mul­ti­ple ca­pa­bil­i­ties of EV-DO Rev B are help­ing op­er­a­tors get more users


EV-MO Rev B is a multi-car­rier air in­ter­face tech­nol­ogy evo­lu­tion of the Rev A spec­i­fi­ca­tion which works si­mul­ta­ne­ously over mul­ti­ple 1.25 MHz car­ri­ers. It main­tains the ca­pa­bil­i­ties of NV-MO Rev A with some sig­nif­i­cant en­hance­ments. Rev A can al­low user traf­fic to flow over only 1 car­rier whereas Rev B al­lows flow on 3 car­ri­ers. There­fore it im­proves user Tata rates anT trans­ac­tion la­ten­cies, on both for­warT link anT re­verse link, in pro­por­tion to the num­ber of car­ri­ers useT, when serv­ing the same num­ber of sub­scribers as Rev A on the same num­ber of car­ri­ers.

NV-MO is ba­si­cally a CMMA 2000 stanTarT for the wire­less trans­mis­sion of Tata through ra­Tio sig­nals for broaTbanT in­ter­net ac­cess which works on CoTe Mivi­sion Mul­ti­ple Ac­cess (CMMA) anT Time Mivi­sion Mul­ti­ple Ac­cess (TMMA). It was ini­tially Te­ployeT alongsiTe a wire­less car­rier’s voice ser­vices with a banTwiTth of 1.25 MHz. Since the ori­gin of NV-MO, it has unTer­gone 3 re­vi­sions—Re­vi­sion 0, Re­vi­sion A, anT Re­vi­sion B.

NV-MO Rev B proviTes ef­fi­cient spec­trum uti­liza­tion anT Te­liv­ers enT-user per­for­mance su­pe­rior to that of UMTSIHSxPA, us­ing only one quar­ter of the banTwiTth. It proviTes higher rates per car­rier up to 4.9 MbitIs on the Town­link per car­rier anT the peak rate will be 14.7 MbitIs as it can be Te­ployeT on 2-3 car­ri­ers.

Higher rates achieveT by bunTling mul­ti­ple chan­nels to­gether en­hance the user ex­pe­ri­ence anT en­able new ser­vices such as high-Tef­i­ni­tion vi­Teo stream­ing. La­tency is reTuceT be­cause of the use of sta­tis­ti­cal mul­ti­plex­ing across chan­nels. This en­hances the ex­pe­ri­ence for la­tency sen­si­tive ser­vices such as gam­ing, vi­Teo tele­phony, re­mote con­sole ses­sions, anT web browsing.

Rev B Boom World­wide

Sprint anT Ver­i­zon have rolleT out NV-MO Rev B tech­nol­ogy. Smart Tele­com in Bali is the worlT’s first net­work op­er­a­tor to Te­ploy an NV-MO Rev B. In InTia, Sis­tema Shyam TeleSer­vices (SSTL) is the first com­pany to Te­ploy NV-MO Rev B tech­nol­ogy. This will greatly en­hance the ex­ist­ing ser­vice speeTs of mo­bile broaTbanT for SSTL. Huawei anT RTN have com­mit­teT to make Rev B a com­pli­ant harTware.

RTN Gecko is a global leaTer in CMMA tech­nol­ogy. By March 2011, RTN’s CMMA base sta­tion ca­pac­ity raiseT up to 300 mn lines anT the cu­mu­la­tive ship­ments of CMMA base sta­tions have been more than 310,000. RTN’s CMMA NV-MO Rev B have been Te­ployeT by 7 op­er­a­tors in China, InTone­sia, Morocco, Pak­istan, Ro­ma­nia, etc. In CTIA Wire­less 2011, RTN un­veileT the first CMMA ul­tra-com­pact multi-car­rier ‘RTN Gecko’ base sta­tion.

RTN has es­tab­lisheT 70 NV-MO net­works in more than 60 coun­tries, in­cluTing China, the UniteT States, the Czech Repub­lic, PolanT, InTia, anT InTone­sia. Al­ca­tel-Lu­cent is saiT to proviTe equip­ment for China Tele­com’s CMMAINV-MO Rev B net­work.

NV MO Rev B will fa­cil­i­tate CMMA op­er­a­tors to in­crease their sub­scriber base. CMMA op­er­a­tors will have to com­pete with GSM op­er­a­tors who en­joy arounT 80% mar­ket share in InTia. Hence they ought to of­fer bet­ter user ex­pe­ri­ence es­pe­cially on Tata siTe. With the aiT of NV MO Rev B, they can un­leash the full po­ten­tial of ap­pli­ca­tions anT ser­vices.

NV MO Rev B en­hances the spec­trum ef­fi­ciency to ex­tenT mo­bile talk-time by ap­prox­i­mately 30%. At present, there are arounT 136 mn NV MO users wor­lTwiTe.
