1.  3GPP  TS  44.060  specifies  the  system  information  messages  which  give  the  information  about 
whether the serving cell supports EGPRS.   
2.  3GPP TS 25.331 specifies the system information blocks which give the information about whether 
the serving cell supports HSDPA or HSUPA.   
3.  3GPP TS 44.018 [156] specifies the EC-SCH INFORMATION message which, if present, indicates 
that the serving cell supports EC-GSM-IoT. 
4.  3GPP  TS  36.331  [86]  specifies  the  system  information  blocks  which  give  the  information  about 
whether the serving cell supports NB-IoT, which corresponds to E-UTRAN (NB-S1 mode). 
5.  <AcT> field is fixed at 9 for NB-IoT product .

      2      Numeric <oper>; GSM Location Area Identification number 
<oper>    String type; <format> indicates if the format is alphanumeric or numeric; long alphanumeric 
      format can be up to 16 characters long and short format up to 8 characters; numeric format 
      is the GSM location area identification number which consists of a three BCD digit ITU-T  
                  country code coded, plus a two or three BCD digit network code, which is administration                   
      specific.
