The glasses prepared under reducing conditions contained Fe3+ ions. The Fe2+/Fe3+ ratio for all glasses increased as the time at wettability test temperature was increased. Iron in the glasses (according to isomer-shift data) was possibly octahedrally coordinated. The Fe environment in glasses very nearly saturated with Fe oxide was most symmetrical. The glasses prepared under reducing conditions exhibited more symmetrical Fe environments than those prepared under oxidizing conditions. The structural symmetry in the glasses very nearly saturated with Fe oxide facilitated the electron transfer reaction, 2Fe3++Fe0=3Fe2+; the conversion to Fe2+ occurred to the greatest extent in these glasses.

The strategy is applicable to any real life PCS and cellular networks. It is shown that by optimally choosing/ arranging parameters, it is not only possible to mitigate the CO-and adjacent PN-offset interferences, sufficient PN-offset values can also be reserved for new cells to be added into existing clusters for future network development.
