hexadecimal. (Example: “00C3”= “195” in decimal)
<ci>: Cell information, composed of four characters and expressed in hexadecimal.
Extended Information: according 3GPP Rel7, four characters are requested, but if
before Rel7, for example the currently network is Rel6 mostly, only the last two
characters is valid, the other characters is invalid and should be ignored. For example,
if the <CI> return 3B3DE1C, only DE1C is valid and could be used as DE1C is the last
two characters.
