Note: Keep some space for future expansion, if required.

B) On- Air Hours:
No. of Studio can also be decided by the On- Air Hours like 24×7, 18×7 or 12×7 etc. But we recommend having Minimum C & D Category Setup at your station. The reason is :

  • This included backup facility in case main on-air studio fails.
  • This will allow doing regular maintenance without disturbing the show going on-air.

C) Multiple Frequency in a city: (Not yet allowed by MIB)
If you are planning to go for having multiple frequency in your city and planning to broadcast different Content format. PLs plan in advance about designing your studios. Which must include one On-Air and On Backup studio at least for each content format. Central Technical area and Transmission area will accordingly required more space than suggested above.

D) NEWS On-Air: (Not yet allowed by MIB)
If you think that News is important content for your station, Add space of aprx. 200 sq. feet for having News On- Air Studio & News Production Studio.
