FREQUENCY SPECIFICATIONS:

Partially rounded to 0,1MHz. Some frequency blocks have been combined into one bigger block.

 

ABBREVIATION:

Partially internationally accepted labels or specific abbreviations used by the "Autoident" feature of Aaronia SPECTRAN spectrum analysers /electrosmog detectors

 

TRANSMITTING POWER:

Maximum permitted or regular transmitting power

 

RANGE:

Always indicated the maximum or average USABLE distance, not the maximum MEASURABLE distance.

MODULATION:

Where "various" is indicated, use of modulation modes varies widely.

PULSING:

Where "YES" is indicated, pulsing might be used only intermittently, in specific modes, or by specific devices.

PROVIDER:

Typical provider. Either the name of the company, or "private" is indicated for mainly non-commercial use. "commercial" is indicated for mainly commercial use, "aerial" for mainly aerial radio, "military" = mainly military use

 

DESCRIPTION:

Detailed description, often with application examples

 

(UL):

"Uplink" mostly means "handheld device" (portable transmitter which transmits towards a tower, like mobile phones)

 

(DL):

"Downlink" mostly means "base station" (fixed transmitter which transmits towards portable devices, like cell towers)
