Mode:
Mode of the cellular network. (Enum TNetworkMode)
2 = GSM/GPRS or DCS1800 network, 6 = WCDMA
Status:
Phone network status. (Enum TNetworkStatus)
0 = Status is unknown.
1 = A network that the mobile device is allowed to register to.
2 = Currently registered network.
3 = A network that the ME is not allowed to register to.
Band:
On CDMA networks, the band and band class of the CDMA network operator. (Enum TNetworkBandInfo)
0 = The current band and band class is unknown.
1 = The network operates at 800MHz on Band A.
2 = The network operates at 800MHz on Band B.
3 = The network operates at 800MHz on Band C.
4 = The network operates at 1900MHz on Band A.
5 = The network operates at 1900MHz on Band B.
6 = The network operates at 1900MHz on Band C.
7 = The network operates at 1900MHz on Band D.
8 = The network operates at 1900MHz on Band E.
9 = The network operates at 1900MHz on Band F.
Access:
On GSM/WCDMA networks, the type of network access. (Enum TNetworkAccess)
0 = This is used when there is no network activity and therefore no RAT active.
1 = The access technology is GSM.
2 = The access technology is GSM COMPACT. However GSM COMPACT systems which use GSM frequency bands but with the CBPCCH broadcast channel are considered as a separate access technology from GSM.
3 = The access technology is UTRAN (UMTS Network).
Bar:
Describes the phone's current signal strength (SSI).
The absolute number of signal "bars" that the phone should display.
