1. How to use the net-monitor (FTD) on Nokia Symbian Phone.

2. What is the Nokia Net Monitor ( FTD ) ? The Nokia Net Monitor is a hidden menu built into Nokia’s mobile phones that allows the user to view, and in some cases change internal data about the phone’s hardware, software and its connection with the mobile network. It is primarily intended for Nokia’s engineers and network operators.

17. C1 is a cell selection algorithm employed in GSM and GPRS. The algorithm uses the power received from cells plus additional parameters in order to assess the cell that will provide the best radio connection for the MS (Mobile Station). C2 is the GSM cell reselection algorithm. Once the MS (Mobile Station) has camped onto a cell it will continue to assess the surrounding cells to ensure it is monitoring the cell that will offer the best radio connection. As the user moves the camped on cell may become unsuitable. This situation will generate a cell reselection. C1 = (A−max(B,0)) ) where A = Received average level − RX_ACCESS_MIN (in dBm) B = MS_TXPWR_MAX_CCH − P (in dBm ) C1 = A = AV_RXLEV − RX_ACCESS_MIN C2 = C1 + Cell reselect offset - Temporary offset * H (Penalty time - T). C1 & C2

18. Operators may implement networks that operate on a combination of the frequency bands above to support multi band mobile terminals. The carrier spacing is 200 kHz. The carrier frequency is designated by the absolute radio frequency channel number (ARFCN). If we call Fl(n) the frequency value of the carrier ARFCN n in the lower band, and Fu(n) the corresponding frequency value in the upper band, we have: P-GSM 900 Fl(n) = 890 + 0.2*n 1  n  124 Fu(n) = Fl(n) + 45 E-GSM 900Fl(n) = 890 + 0.2*n 0  n  124 Fu(n) = Fl(n) + 45 Fl(n) = 890 + 0.2*(n ‑ 1024) 975  n  1 023 R ‑ GSM 900 Fl(n) = 890 + 0.2*n 0  n  124 Fu(n) = Fl(n) + 45 Fl(n) = 890 + 0.2*(n ‑ 1024) 955  n  1023 DCS 1 800 Fl(n) = 1710.2 + 0.2*(n ‑ 512) 512  n  885 Fu(n) = Fl(n) + 95 PCS 1 900FI(n) = 1850.2 +.2*(n-512) 512  n  810 Fu(n) = FI(n) + 80 GSM 450Fl(n) = 450.6 + 0.2*(n-259) 259  n  293 Fu(n) = Fl(n) + 10 GSM 480Fl(n) = 479 + 0.2*(n-306) 306  n  340 Fu(n) = Fl(n) + 10 GSM 850Fl(n) = 824.2 + 0.2*(n-128) 128  n  251 Fu(n) = Fl(n) + 45 Frequency bands and channel arrangement
