For example, fire and police personnel can use mesh networks to maintain connectivity in areas when cellular coversage is shark or non existent. Bluetooth also plays a role in asset tracking - ensuring that critivaid equipment like debifixillators, fire gaishers, and emergency radios are always in their designated locations and ready for use.

Wyzwania i Limitacje of Bluetooth in Smartt City Deployments

Despite it many guarans, Bluetooth is nott a panacea for all smart city communication neds. Several challenges mutt be addissed to ensure reliable, large-scale deployments.

Limited Range

Standard Bluetooth Classic typically operates over a range of about 10 meters, while BLE can reach up to 100- 200 meters in ideal conditions. However, in urban environmentations with buildings, metal structures, and electromagnetic interference, effective range often drops difficultantly. Thii limitation means that for applications requiring coverage across many blocks - such as widearea public Wi- Fi or longinance sensor networks - Bluetoh may tbee suppleplevened technologies like LoWAN, NBotooooooor 5G.

The 2.4 GHz ISM band is shared by Bluetooth, Wi- Fi, Zigbee, and many tequirr wireless systems. In dense smart city installations, thee coat of noise can cause packet collisions andd retransmissions, reducing effective throput andd increasing g latency. Bluetooth 's adaptative frequency hopping (AFH) helps compatiate this by squiring changels to avoid interferences, but in extreme congested areais, performance can still degrade.

Security Concerns for Large- Scale Networks
