hi all masters

iphone 2g network problem no emergeny call

network on 5 second and emergeny call empty network

full firmware and jalibreak 1.1.4 and ziphone same 5 second network empty end

full firmware 3.1.2 and blackrain1 same problem

what is your modem !!!

wifi good work no problem

To determine the received power in downlink, the predicted path loss is subtracted from the base stations's output power (incl. antenna gain/pattern). Optionally several losses (cables,...) can be defined and are added to the predicted path loss values (if applicabale).
SNIR targets must be fulfilled in each receiver to obtain a good signal quality (low BER). To determine the SNIR, WinProp superposes

• thermal noise (depending on the bandwidth of the channel)
• CCI (co-channel interference (from other transmitters radiating on the same carrier frequency)).
• ACI (adjacent channel interference (from other transmitters radiating on the adjacent carrier frequency)).

The user can display all locations where the SNIR is sufficient for a good reception of the signal and the user can visualize all areas where the signal quality is reduced because of the low or even negative SNIR.

WinProp can model an arbitrary number of types of mobile stations (e.g. handsets, notebooks, vehicular terminals,...) and all of them with their individual SNIR targets, noise figures, general losses, fast fading margins,.....The mix of mobile stations (e.g. 50% handsets, 30% vehicular, 20% notebooks) can be defined as well by the user.

Of course,for multi service analysis (e.g. speech and data with different SNIR targets and capabilities of the user terminal) individual outputs are computed for each service. During the planning process the user can already analyze at which location which service is available.

For each service the target SNIR as well as the min. required signal level can be defined individually (including different values for up- and downlink and different types of mobile stations with different transceiver capabilities).

Restore 3.1.3 procedure is here but maybe your phone problem is hardware...

Good Luck Buddy
