LTE RF Planning Guideline

[louvre]

Hi,

Please find the RF planning guidelines from Motorolla. I was reading through it and found it interesting read and someone of us has been looking for such a Guide.

Appreciate some reputation for it.

AAAAhhh. Thats a very long list.

[pathloss]

I'm sorry to say it, but me to I have an error on decompression.

[louvre]

Bummer,

I am re uploading the files now. Sorry if caused you guys problem. hope this work.

[pathloss]

Thank you very much for your effort. I tryed to decompress the file in osx and in winxp, both do fail. (unkowen compression methode)
