zigbee,NB, lora, who is best?

There is many discussion about which wireless communication is most effective.

According to our 10 years of oversea project commissioning experience. we can evaluate from following aspects:

communication distance, NB technology is signal coverage from mobile tower to individual lamp directly, there is not much distance limit between lamp, however in most of oversea country, 2G to support NB is not well cover and also not support at priority. most of case is offline(especially at busy time). so far only in northwest china is good

Lora has low power consumption and long range radio advantage, but the bottle neck is also infrastructure of network base.cost is also high. can't work real good.

zigbee, communication distance is within 2km, and even occasionally lost connection, but so far it is most suitable for street lighting solution, as there is very limit data also not required to full time connection by gprs(they will re-connect each other and create good mesh network internally.

aurora solar launched so many projects with smart system by use zigbee technology and our own gateway and app, it real work fantastic..
