HF Control Unit is located at Telecommunication Headquarters, Pattom,
Thiruvananthapuram. This unit is functioning round the clock in the headquarters
with Sparrow, Technical cadre Monitoring Cell, CoB and HF Communication.
Sparrow (State VHF Control Station) at HF Control acts as a state-wide control of
VHF communication, properly controls the communication in trunk line around the
clock as per Radio Procedure.
Kerala Police established Technical Cadre by deputing Telecommunication staff in all
Sub divisional Police Offices. Technical Cadre staff performs care and maintenance
of each and every digital/electric/electronic equipment in all police station and other
offices. In this way Government can save a huge amount by avoiding AMC to various
equipment. Technical Cadre Monitoring Cell in HF Control unit guides and
supervise the works of the Technical Cadre and submits daily/ weekly/ monthly
reports to higher-ups. This team strictly monitor and follow-up pending works by
contacting concerned officers.
COB (Communication Backbone) a high security intranet communication system
in this unit handles all outside district messages to the offices without CoB node in
Thiruvananthapuram.
This unit also act as a control station of High Frequency (HF) communication
which is the traditional means of communication established much before voice
communication and still follows based on its reliability and wide coverage. As HF
communication equipment can transmit signals to more than 1000 kilometers using
proper antenna installation, we can communicate with middle region of our country.
HF communication is currently kept as a standby mode in Kerala Police.
