Research on frequency of signals in different electromagnetic frequencies has highlighted the complex, often mysterious world of electromagnetic waves
What we know
These are the groups of radio frequencies that are commonly used in mobile phone service and – at present – in wide-area WiFi networks. They are called categories 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, 144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 157, 158, 159, 160, 160, 161, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 191, 194, 195, 196, 197, 198, 199, 200, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211, 211, 212, 213, 213, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 230, 231, 232, 233, 233, 235, 236, 237, 237, 237, 239, 239, 240, 242, 243, 244, 245, 246, 247, 248, 249, 250, 255, 256, 256, 257, 258, 259, 260, 258, 260, 260, 258, 260, 260, 258, 261, 262, 267, 267, 268, 269, 270, 270, 268, 270, 270, 268, 272, 277, 270, 279, 280, 285, 280, 281, 282, 282, 283, 283, 283, 284, 285, 285, 280, 289, 287, 291, 290, 293, 294, 294, 295, 294, 296, 295, 296, 296, 296, 298, 298, 298, 298, 298, 299, 300, 301, 302, 303, 304, 304, 305, 306, 307, 307, 308, 309, 309, 309, 309, 309, 319, 319, 321, 321, 321, 328, 337, 334, 339, 339, 345, 346, 349, 349, 348, 349, 358, 359, 368, 374, 365, 370, 375, 372, 368, 374, 372, 373, 374, 371, 367, 367, 374, 367, 369, 368, 371, 371, 367, 374, 369, 367, 367, 367, 367, 366, 364, 371, 374, 364, 363, 364, 364, 366, 367, 365, 364, 359, 369, 364, 364, 358, 364, 368, 364, 371, 363, 364, 364, 364, 367, 364, 359, 366, 368, 364, 368, 36,364.
