If the two are able to establish a direct communications link, without requiring the use of any relays, repeaters, etc.How the communication of UAV can be done from ground station without any delay??
Actually I have to setup a communication link between UAV and a base station that would be kept at ground. I thought about using radio module for video streaming but there'll be lag of half second. So what else is the option for video streaming with no lag??If the two are able to establish a direct communications link, without requiring the use of any relays, repeaters, etc.
In practice this means the ground station is 'local' to the UAV area of ops.

On a practical level, there really are none. The more information which needs to be relayed, the greater the time/lag and/or the greater the bandwidth required, and the greater the distance between the UAV and control operator and/or intervening terrain features, then the more links in the communications chain. All of these are going to have an impact the communications.Actually I have to setup a communication link between UAV and a base station that would be kept at ground.

So for minimum lag which device should I prefer ??On a practical level, there really are none.

If you want video streaming from the UAV back to a control operator, there is going to be some lag unless the two have a direct link and even then, depending on the level of detail, the transmission will require time.
I cannot really tell you, as there are too many variables I do not know, and I admit I am not an expert in this area. I just happen to know some of the areas where issues can/do occur.So for minimum lag which device should I prefer ??
There is always some delay, how ever fractional, things are rarely ever simultaneous to all observers. I doubt your planning a UAV for operation on the moon or Mars, but still something to concider (particularly if your using sat links).How the communication of UAV can be done from ground station without any delay??
