No Its not using different one same WCDMA/Ev-DO/UMTS (2100 Mhz) the same frequency they hold for Vfone/Evo services 1900/2100 Mhz
What they brought with 4G (Truely 3G) devices is that can create 12 concurrent connections to tower and bonding them into 1.
I didn't get it. WCDMA interface relates to UMTS family and Ev-DO relates to CMDA2000. Both can be deployed in your mentioned frequencies but have different modulations. Charji device indicates the network UMTS based when its switched on PTCL LTE network and CDMA2000 when its fallbacks. So, my question is, how it is possible to convert into WCDMA using 12x of Ev-DO when they don't relate to each other, i'm confused now.
