how come broadcasters can still broadcast from tehran. how about al jahzeera

Tehran can still have broadcasters on air because broadcasting usually depends on a mix of studio facilities, transmission networks, backup power, and distributed relay infrastructure, not just one building in one city. If one site is damaged or disrupted, signals can sometimes be rerouted or kept alive through alternate transmission paths; reports about Iran’s state broadcaster say its signal kept going even after strikes hit its Tehran headquarters.

Why this is possible

• Broadcasting is decentralized. A newsroom, a master control room, and the actual transmitters may be in different places.

• Backup systems matter. Broadcasters often have redundancies such as backup power, alternate uplinks, and remote production workflows.
• State networks get priority. In Iran, domestic broadcasting is dominated by the state-run IRIB system, which has a monopoly over local radio and TV services.

What about Al Jazeera?

Al Jazeera has had a complicated history in Iran, including past bans and jamming incidents, and Reuters reported Iranian interference with its broadcasts in earlier years. More recently, reporting has said Al Jazeera was among the few foreign media outlets still broadcasting from within Iran during periods of heavy media restriction, though the exact technical setup was not clearly explained.

Bottom line

So if you’re asking “how can they still broadcast from Tehran?”, the short answer is: because the broadcast system is more resilient than a single studio, and in some cases the signal can survive even when the main building is hit. Al Jazeera’s situation appears different from Iran’s state broadcaster, but it has also been able at times to keep reporting from inside or around Tehran despite interference and restrictions.
