LE 1M AND LE 2M PHYs

Hello Bretley,

Well the LE 1M PHY is the standard 1 Mb/s bit rate, 1 Msym/s symbol rate. Each bit maps to a single radio symbol. The 2M PHY is double the rate, as it is being modulated at twice the speed. This comes at a small cost to range, and the throughput won't necessarily be doubled. 

You can read a bit more on what is new in advertising here.

Was this the mathematical theoretical explanation you were looking for? If not, could you expand a bit on what you are wondering about?

Regards,

Elfving

Hey Elfving,

Thanks for response.

I want to have a deep understanding of LE 1M and LE 2M phys something like mathematics or diagrammatically explanation.

Gentle Reminder 

Could you expand on what parts of the concepts you'd want a mathematical or diagrammatical explanation of, or what could be made clearer?

Like if someone asks “What is LE 1M/ 2M Phy?”

As all blogs say LE 1m uses one bit per symbol and other uses two bits enhancing data rate!!

but how exactly is this done?

how symbols are mapped ?

how the Phy operation works actually leading to increased speed but constraint on range?

Hey Elfving, 

Gentle Reminder Please if you could help me with the LE 1m and Le 2m phys explanations at earliest please
