Hello everyone, I am working on Smart Meters and for this, I have to transmit the data measured by Smart meter to a cloud server using IoT. For this, I need a cost-effective and more secured network for data transmission. Can someone suggest to me what should I use 1) WiFi 2) NB-IoT 3) LoRaWAN. I am actually willing to use WiFi as it is cost-effective and can easily available but the issue is its security. I have read on the internet that most WiFi routers use WPA2 + AES encryption but still it can be hacked. I need help in securing a WiFi network to prevent cyber attacks. But if someone can suggest me any other cost-effective and more secured option to work with then it is really appreciated.

No matter what you do to secure a connection someone will be able to undo it. People may be able to hack wifi details to read your data but if you can encrypt the data in a robust way you make it less likely someone will be able to decode it in a sensible amount of time.
The trick is to make the decoding such an expensive task in terms of hardware cost/time that most people give up.
Most companies etc use a radius server to authenticate wifi connections. You can have a raspberry pi running as a radius server (I have done this here) and it will help stop casual attackers getting access to your network.
The beauty of this is that the handshake to exchange data and authenticate is encrypted as is all subsequent traffic.
