5.8GHz Spectrum

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).
