Location: Greater Kolkata, Agarpara - Kolkata - 700109

Network Review: 4G Network
Airtel:
Airtel is the best in my area, providing a consistent speed of 12-30 Mbps indoors and 50-65 Mbps outdoors. The nearest small BTS is around 234 meters away from my location, which is an Indus Tower VI that supports 2100, 2500, and 1800 MHz frequencies.
Airtel has enabled 4C (Carrier Aggregation) including the L900 MHz band, but most of the time, it latches onto 2C. During Durga Puja, I observed that they disabled Carrier Aggregation and used only the 900 MHz band for calls and 1800 MHz for data transfer. Every Sunday, they also automatically disable Carrier Aggregation.
During midnight, Airtel shuts down the nearest cell across all frequencies and forces the connection to latch onto a tower 1.8 km away, which is located in a densely populated area.
VI (Vodafone Idea):
VI does not offer Carrier Aggregation in my area. Only re-farmed L900 MHz and 1800 MHz bands are active. For postpaid users, they enable the 2500 MHz band (I tested this using my friend's postpaid SIM). The speed for prepaid users is around 10-20 Mbps, while postpaid users get 20-45 Mbps, sometimes even higher.
Jio:
Jio is my primary connection, but it has been terrible lately. Despite having many BTS towers, there is no speed and no proper call quality. It constantly forces the connection to latch onto small cells. For calls, it uses the 850 MHz band, and for data, the 1800 MHz band. As a postpaid user, I typically get speeds of 2-5 Mbps, and during peak hours, it sometimes drops to 600 Kbps. 5G is available outdoors but not indoors.
BSNL:
BSNL is not worth mentioning—it's a waste of money.
Conclusion:
In terms of quality, Airtel is still the best network in my area.
