*LR test p value for operator effect within country <0.05. †LR test p value for operator effect within country <0.001. ‡LR test p values for operator effect overall <0.001. §Interoperator range: lowest mean output power – highest mean output power in centres with more than one operator. ¶In Canada the GSM network uses a 1900 MHz frequency band with the same standards as the 1800 MHz band (table 2).
GSM, Global System for Mobile communications; LR, likelihood ratio; PMax, maximum power: 250 mW at 900 MHz and 125 mW at 1800 MHz; PMin, minimum power: 0.4 mW at 900 MHz and 0.13 mW at 1800 MHz.
