TECHNICAL DETAILS

Technical Details

The Migo is an all digital phone that operates on

both Code Division Multiple Access (CDMA)

frequencies: cellular services at 800 Mhz and

Personal Communication Services (PCS) at 1.9 Ghz.

CDMA technology uses a feature called DSSS

(Direct Sequence Spread Spectrum) that enables the

phone to keep communication from being crossed

and to use one frequency channel by multiple users

in the same specific area. This results in a 10-fold

capacity increase when compared with analog mode.

In addition, features such as soft / softer handoff,

hard Handoff, and dynamic RF power control

technologies combine to reduce call interruptions.

The Cellular and PCS CDMA networks consist of

MSO (Mobile Switching Office), BSC (Base Station

Controller), BTS (Base station Transmission System),

and MS (Mobile Station).

* TSB -74: Protocol between an IS-95A system and

ANSI J-STD-008

1xRTT system receives twice as many subscribers in

the wireless section as IS-95. Its battery life is twice

as long as IS-95. High-speed data transmission is

also possible.

The following table lists some major CDMA

standards.
