Hi Minho, we can discuss then adding an additional shadow fading variable when people are standing next to each other. Then we may also thing about head/hand blockage for mobile devices.

Thanks,

Vinko..

Hi Vinko,

 

Correct. It can be seen that most of HEW usage models especially among high density STAs deployment have 0.5~1.0 users / m2.

Maybe in many cases, devices is not likely to have LOS link to AP for those usage models.

Thanks.

Hi. Minho, do you mean that people are standing next too each other so that there is human blockage?

Thanks,

Vinko..

Hi Vinko and Shahrnaz,

 

Thanks for your introductory presentation on channel model today.

Could I ask some question on HEW outdoor channel modeling as follows?

-       Is there any mismatch problem if we simply apply the cellular-based outdoor channel models to the HEW outdoor environments, in most of which so many people are populated within a very limited area (over than 0.5 person / m^2)?

-       Even though it’s 5GHz band (not millimeter wave), I have some doubt on whether we may need to additionally define side effects such as human body blockage due to too high density of deployment or not.

 

Thanks a lot.

 

Best Regards,

 

Minho
