Reliance JIO Infocomm Logo_bigThough many of our impatient readers are skeptical about Reliance Jio’s commercial launch of 4G services, let me tell you guys one thing, the services will be so fast that you will never be impatient. What I believe by seeing the progress of laying OFC across Kolkata, Jio may go for launch at several cities at one-go in next 90 days and there is little chance that they start offering voice during initial launch.

Spectrum on 2.3Ghz for data-only to be used for lte-tdd services while role of recently acquired 1.8Ghz spectrum in 14 circles is yet to be confirmed. In most probable situation Jio will use 1.8Mhz band for more bandwidth in selected pockets along with WiFi and FTTx. Jio can wait and go for carrier aggregation for lte-advanced solution.

At this point VoLTE is not mainstream, and thus Jio can not directly enter into voice market. Other 4G operator in country, Airtel is offering 4G voice using circuit switch fallback mechanism.

Data-only approach is not a good idea as telecom market of India still earns majority of revenue from voice services , and Jio may jump into MVNO (Mobile Virtual Network Operator) way to piggyback over an existing mobile operator to be the game changer and a real threat to existing voice and data service providers incl. incumbents. [ MVNO = A mobile operator which has no network, no spectrum but buys a wholesale data, voice or text from an existing operator and sells to end customers generally at a very low cost with their own billing system.]
