2.4GHz Spectrum
The 2.4GHz band is the most common band for most wireless devices ranging from Home Routers and HotSpot locations e.g. Caravan Park, Shopping Centres and Cafés to Portable mobile devices such as Mobile Phones, Tablets and Games Consoles.
Wireless Standard for this band is shown as 802.11 b / g / n / ac.
The spectrum operating frequency range is 2412 – 2484MHz. The OFCOM /ETSI standard for UK Operating channels are between Channel 1 - 13.
The maximum EIRP (Effective Isotropic Radiated Power) is 20dBm / 100mW.
EIRP (dBm) = Output Power (dBm) + Antenna Gain (dBi)
