FITEL's PHS business has achieved quite successful growth in 2002
and especially for recent two months that's remarkable thanks to the
sales promotion "No Monthly Charge". We decided to stop the no monthly
charge from first of this year, but the charge is minimum cost. In
Taiwan market where the GSM is dominant, it's essential to reduce
PHS subscribers' usage fee burden in order to compete with the GSM.
Current PHS subscribers are more than 500,000 and ARPU (Average monthly
Revenue Per User) is NT$650 (Approx. US$18).
Several hundred CSs (Cell Stations) are installed monthly to expand
the service area and the number of CS reached 8,153 by the end of
2002. We expect to cover Kaoshiung area within this year.
The most important aspect of the successful PHS business is the terminal
(Personal Station = PS). Currently three models are available in the
market. One of them is SANYO
Electric Co., Ltd's "J88" which sold 450,000 units and this model
is sold more than any other handsets, including GSM, in Taiwan. "J95"
launched in last year is the first color LCD handset in Taiwan including
the GSM handsets. This is a high-end and high price model, however,
ARPU for data communications is also high. Clamshell type "J89" with
four level monochrome LCD and exclusive button for easy access to
the data application was launched last month. This is a low price
model targeting the young people and we expect to increase the subscribers
up to one million by the end of this year mainly with this model.
We are also studying the possibility of launching the PHS/GSM Dual-Mode
PS, voice only PS and data cards (PCMCIA, CF (Compact Flash), SD)
as well. We think that the packet mode would be important for data
applications and accordingly, we are changing our network to be available
for the packet mode.
(Presentation on "J88" and "J95" using photos
etc. and on "MiMi(Mobile Information Mobile Internet)"
data access procedures comparison for
those two models was made.)
In order to differentiate from the GSM, the international roaming
service to Japan was launched last year and this service has been
well accepted by high-end users traveling to Japan. MiMi service portal
enhancement is also making good progress and as for the SMS (Short
Messaging Service), now it's become possible to connect with three
GSM operators and, in the near future, with two more which used to
be difficult. By the end of February, SMS exchange will also become
possible with China Mobile's subscribers as well.
As for Promotion Strategy, it was quite successful to eliminate the
monthly fee and we will focus on low radiation issue as one solicitation
from now on. And further, to suppress the subsidy as possible would
be important.
According to our traffic analysis, 44% of the total traffic is outgoing
calls to GSM phones and 23% is PHS-PHS connection which is increasing.
The combined data traffic of MiMi and WiWi (Wireless Information Wireless
Internet : usage as wireless modem) is 15% and this figure is fairly
high to show that the data communication is successful.
Our revenue analysis shows that the revenue from calls to the GSM
occupies 60% due to its high tariff and only 8% is earned from the
data communication as its fee is less expensive.
2) SD Card
type PHS Terminal AH-S101S : (the presentation
material is here.)
SII is one of the PC card type PHS terminal (Personal Station
= PS) vendors and today I'd like to introduce the latest and the smallest
PHS terminal called "AH-S101S" which was developed last
year with DDI
POCKET, Inc.'s cooperation.
SII launched the PHS data modem card in 1996 almost at the same as
the PHS commercial service started, however, there were mobile users'
strong requests for more sophisticated and comfortable device because
this PC card needed a connection cable and PHS terminal to use.
PC card type PHS terminal was developed to accommodate such requests
by simply inserting it into the PC's card slot for wireless Internet
access. Such concept was well accepted by mobile users. After that,
other PC card type PHS terminals available for 32 Kbps PIAFS, 64 Kbps
PIAFS and packet data communications have been introduced as the data
communications service advances.
We put all of these features into an SD (Secure Digital) card
size device and such a small device can be applied not only to the
consumer market but also to the embedded system markets as well.
One of this device's concepts is to provide the standard device. The
term "Standard" means to be acceptable to many platform
vendors and this is the very reason for having selected the SD card.
Further, it's also applicable to other electronic devices than the
PC and PDA (Personal Digital Assistant) such as video camera, audio
set, set top box, car electronics, security system etc. This is also
one of those concepts.
There were two subjects to be solved for developing this device, one
was to develop the BBIC (Base Band IC) including SDIO (SD I/O) interface
and the other was the RF layout optimization to get enough gain by
small antenna. Applicability to DDI POCKET's 32 Kbps Packet/32 Kbps
PIAFS/64 Kbps PIAFS services, small size of 55 X 24 X 6.6mm, light
weight of 6g, SDIO Interface are some of the main items which are
included in the specification of "AH-S101S".
Platform and device driver are key points. Driver for "Palm"
has already been completed, however, for TOSHIBA CORPORATION's "Genio"
is still a betaversion, for "PocketPC" and other platforms
are now under development.
We have a plan of adding 128 Kbps Packet mode type and "Memory
Stick" card type terminal and we have been receiving inquiries
to those from more than 20 embedded system makers or vendors. This
is because AH-S101S is a complete terminal rather than only a module
and can easily be incorporated in the system.
"SD Card Association" was established for worldwide promotion
of the SD card interface and originally started with the SD memory
interface, however, it's focusing on SDIO interface at present. "PHS
Task Group" was formed within "I/O Working Group" to
standardize the "SDIO PHS Interface Specification" and its
Version 1.0 is now being discussed at the Technical Committee to be
available for everyone after it's officially released
