The 5.8GHz band is becoming more available on wireless devices, including: Home Networks, HotSpot Locations (e.g. caravan parks, shopping centres and cafés) and Portable Mobile Devices.
Wireless Standard for this band is shown as 802.11 a / n / ac.
The spectrum operating frequency range is 5150 – 5850MHz. The OFCOM / ETSI standard for UK Operating channels split into 3 bands: Band A, Band B and Band C.
The maximum EIRP (Effective Isotropic Radiated Power) depends on which band is in use (see below).
5.8GHz Band A - UNII-1 Lower and UNII-2 Middle (5150 - 5350MHz)
Indoor Use Only
Band A is used for indoor 5GHz use i.e Home Networks, Public HotSpots and Cafes.
The maximum EIRP for Band A is is 23dBm / 200mW.
5.8GHz Band B - UNII-2 Extended (5470 - 5725MHz)
Indoor and Outdoor Use
Band B is used for indoor and outdoor 5GHz use i.e Dual Band Routers, HotSpots and Cafes
Band B can also be used by WISPs (Wireless Internet Service Providers) for connecting Access Points and CPEs (Client Premise Equipment).
The maximum EIRP for Band B is 30dBm / 1000mW.
5.8GHz Band C - UNII-3 Upper (5725 - 5850MHz)
Fixed Wireless Access
Band C is used for long range PtP (Point to Point) or in some cases (PtMP) (Point to Multi-Point) wireless links. For example, backhaul connectivity between two locations.
Band C requires a “Lite Licence” known as the Fixed Wireless Access Licence obtained from Ofcom, this licence has an annual fee.
The maximum EIRP (Effective Isotropic Radiated Power) is 36dBm / 3891mW.
EIRP (dBm) = Output Power (dBm) + Antenna Gain (dBi).
