Overview

Frequencies used by a service.

By default, #reception_f is set to the same value as #transmission_f since most services rely on simplex (aka: non-duplex) two-way communication. For services with one-way communication only such as ATIS, the #reception_f has to be set to nil explicitly!

Cheat Sheet in Pseudo Code:

frequency = AIXM.frequency(
  transmission_f: AIXM.f
  callsigns: Hash
)
frequency.reception_f = AIXM.f or nil
frequency.type = TYPES or nil
frequency.timetable = AIXM.timetable or nil
frequency.remarks = String or nil

end

Instance Attribute Details

#callsigns ⇒ Hash

Returns map from languages (ISO 639-1) to callsigns.

Examples:

{ en: "STRASBOURG CONTROL", fr: "STRASBOURG CONTROLE" }

#reception_f ⇒ AIXM::F?

Note:

One-way services such as ATIS should set this to nil and simplex (aka: non-duplex) communication should set this to #transmission_f.

Returns frequency for reception (incoming).
