PHS has incoming calls from the beginning, learned lessons from
CT-2 (I remember handsets with built-in pager), but it didn't
have handoff, which was added later when the customers started
to defect to PDC in volume.
I still see CT-2 and PHS the same. you also agree that they
are for the same low-end market and we can see clearly that
they have exactly the same fate - up and down over 3 years -
CT-2 had "bad luck" that it didn't have the data requirement
as PHS to keep the coma breathing. for more than 3 years PHS
subscribers draw a flat line at around 5.7 some mln, a line
like what we see in an ICU.
the coverage, for mobile networks it's like painting, that
you have big and small brushes and work carefully at hands,
lips, and eyes, but quickly at the clothes and carelessly
at the backgrounds, trees and clouds.
Ericsson RBS 2206 basestation can, theoratically, cover
maximum 121 kms, a range that is almost over-the-horizon.
and you can have small repeaters to patch a shadow or even
a room (DoCoMo have their equipment in Motown-2, Roppongi).
... you don't need someone to tell you this.
for PHS, it's like one tries to paint a wall with a Japanese
stamp "hanko", anything more stupid and costly? PHS wastes
money ... and it wastes our time.
