    tergantung channelwidthnya, pakai 5 Mhz, 10Mhz, 20 Mhz, atau 40Mhz.
    bandwidth freq 2,4 ghz hanya sebesar 100Mhz (2400-2500 Ghz) dengan deviasi antarchannel = 5Mhz
    channel 1, Frequensi center(Ft) dimulai dari frequensi 2412 Mhz (2409,5 - 2414,5), channel 2 (2412+5) = 2417 Mhz dst

    overlapping artinya apabila channel yang satu menimpa area channel yang lain
    apabila anda main di channelwidth(CW) = 5Mhz, maka semua frequensi tidak ada overlap

    kalo CW 10Mhz, maka pada channel 1 deviasinya berada di 2407Mhz - 2417Mhz (2417-2407=10)
    sedang Ft channel 2 berada di 2417Mhz berarti channel 1 mengoverlap channel 2 sehingga channel 2 tidak bisa digunakan
    sehingga channel berikut harus di channel 3. atau amannya di channel 4 (menurut IEEE, harus ada spasi/gap = 2 Mhz)
    frequensi yang aman di CW 10Mhz adalah 1, 3, 5, 7, 9, 11, dan 13 (IEEE = 1,4,7,10,13)

    CW 20 Mhz, Ft channel 1 = 2412Mhz (2402-2422) dan mengoverlap hingga channel 3 (2422) sehingga channel berikut yang bisa digunakan adalah channel 5 ft = 2432Mhz (2422-2442)
    channel yang aman di CW 20Mhz adalah 1,5,10 , dan 14 <- soalnya g ada ch 15, dan hanya channel ini yg jaraknya dari channel 13 sebesar 10Mhz. (IEEE = 1,6,11, dan 14)

    CW 40Mhz, hanya aman pada 2 channel saja..
    Ft = 2402 + 20 = 2442 (channel 3) dengan range 2402 - 2442
    dan channel berikut
    Ft = 2442 + 20 = 2462 (channel 12) dengan range 2442 - 2482

    kalo bw gede n butu stabil, pake 5.x

    kalo pertimbangan budget pake 2.4 tapi yaa itu... 2.4ghz ping nya ga semulus 5.x karena pertimbangan sinyal tetangga
