wireless, cordless, landline

[Ju]

1. Besides cell phone, I have a wireless telephone at home too.
2. Besides cell phone, I have a cordless telephone at home too.
3. Besides cell phone, I have a landline at home too.

Are the above sentences the same in meaning?

No.

"Besides a cell phone, I have a landline at home" seems the most natural to me. You are saying you have cell phone and a home phone (traditional landline)

A "wireless" is the same as a cell phone, basically. Cell phone companies call themselves "wireless" providers.

A cordless phone is a type of phone connected to a landline that works only in the general area of the base unit. But it doesn't contrast with "cell phone."
