Dears,,

In addition to the below question , first what do you mean by 24 AMPS ?, 2^nd Does ipaccess covers up to 25 KM or it needs amplifiers or one ipaccess antenna can cover that distance can you explain?

Thanks,

Omar Atia

Hi Guys,

The ip.access nanoBTS (at least model 139) do implement timing advance. We have used them in a macro network coupled with 24 AMPS for nearly a year now and they work quite effectively. They work right up to the 25 KM timing advance limit.

Kind Regards
