Good news for all on this subject matter.

Digi is installing its broadcast tower somewhere around Block F. Expected to be ready around early Jan.
Maxis's some where around Block I. Ready by Feb.
Celcom expected to start installation after CNY.
U mobile also did its preliminary survey. Hopefully some time next year.

Maxis also looking into installing fiber optics. But date is less certain.  Will update when I can get more info.

If you look at their location, it is quite far from residential block (for the short range power output of such devices - after 3-4km even your mobile will have problem picking up a good signal). If you are standing in front of the device and within 1 meter then it may be a different story. Just look around - there are so many such devices - very frequently mounted on top of shop houses. Look carefully there should be one within 4 km of where u are living now otherwise u will suffer from poor mobile network services.
