I. Brief History of the Unit:

Mizoram Police Radio Organization (MPRO) was established immediately after the formation of Union Territory of Mizoram in 1972 under the administrative control of Mizoram Police to provide Wireless Communication in the state primarily for maintenance of law and order and prevention and detection of crimes.

One Inspector (Operator) P.C. Laldinga was posted at Aizawl as the overall in-charge of communication and was fully responsible for establishments of office, expansion of man-power, training etc under the close supervision of Superintendent of Police (PHQ) to look after 7 (seven) Wireless Stations namely Aizawl, Serchhip, Lunglei, Champhai, Tlabung, Kolasib and Saiha. Pu P.C. Laldinga started communication with all sorts of handicap. The present MPRO Headquarter land earlier belonged to PWD and Assam Rifle. Knowing the good quality of signal; he approached Government for allotment of MPRO land and later on MPRO Headquarter was set up at Khatla, Shijav Tillah located adjacent to Mizoram PHQ.

Consequent upon the murder of 3(three) top ranking Police Officials in January 1975 in Aizawl, the Govt. of Mizoram felt the need of having an officer of the rank of Superintendent of Police to head the unit and subsequently created SP (Wireless) post vide Order No. HMP 32/75/26 Dated 19th April 1975 to augment and strengthen the capabilities of this Organization in order to cater for the basic communication needs of Police and its administration. MPRO had to face all types of problems such as non-availability of wireless equipments, training of communication personnels and lack of accommodations etc etc. apart from this the prevailing insurgency in 1975, jungle mountains of Mizoram and lack of road communication facilities made communication system more difficult.

During the period of 5(five) years from 1994-1999, MPRO had handled messages of 1393 lakh of group of words and about unrecorded messages (QST) worth 600 lakh groups of words were transmitted in MPRO net for discharging Mizoram Police including other departments. This means that MPRO nets alone transmitted about 2000 lakh group of words. If the messages handled by MPRO were charged at the rate of telegram express i.e. Rs.1 per word the total work done by MPRO net alone will come to be 20 Crore during five years. The total budget allotment of MPRO during the said five years was Rs. 19.2 Crores. This budget provision includes expenditure like salary, travelling expenses, office expenses, rent, minor works, M & E, MV, maintenance, M&S, other charges etc etc. The above data clearly shows that MPRO has made a saving of Rs. 80 Lakh against the sanctioned budget if the message handled by them were  charge at the same rate of Telegram express. Data mentioned above clearly shows that MPRO wireless net handled 5% more messages every year in spite of increasing wireless user Department like P & E, PHE, PWD, Excise, Industry etc. Use of wireless nets of their own by other departments seems to be encouraging because this will prevent unnecessary increase of message to Police Wireless net which will in turn can hamper the efficiency of Police Communication system.

There were 23 (twenty three) Police Stations in the Union Territory of Mizoram. All these Police Stations were provided with HF(CW) and RT communication. Soon after Mizoram achieved its statehood in the year 1987, MPRO has also tremendously grown into its manpower having total sanction strength 763 at present to look after 87 Police Radio Stations.

It is worthwhile to mention that the MPRO is the vital link amongst the various state Government Departments in general and Police Department in particular. The organization has in fact made a remarkable achievement over the year for transmitting and receiving official messages of various Departments through MPRO wireless network at free of cost due to lack of communication in the state.

Rapid growth of technology has inevitably made the organization to update its communication system to along with modern technology. Hence a trunking system was installed in the year 1997 and scrambler sets too were procured. In addition to these, data communication through VHF by using Computers and Modems (POLNET) have already been established in Kolasib, Lunglei and Saiha connecting with Hqrs. Aizawl and thus the communication network have improved tremendously at very high speed thereby increasing police efficiency.

Mizoram Police Radio Organization (MPRO) came into existence in 1972 when Mizoram became an U.T from the Lushai Hills District of the then Assam State. Initially there were seven PR stations functioning at that time and they were :- 1). Aizawl. 2). Lunglei. 3). Saiha. 4). Tlabung 5). Kolasib.  6). Serchhip.  7). Champhai.

The administration of the organization was looked after by S.P (Hqrs) from PHQ, Mizoram and the permanent S.P (Wrls.) was posted w.e.f 19.4.75 till today. From the initial staff strength of around 100 personnel, the organization has increased its activities throughout the state and now the total of staff strength is 747 and has about 85 PR Stations.

BRIEF HISTORY: Communication by scientific means is an important part of today’s technology. The scientific improvements in modern communication have brought different corners of the world closer than ever before. The need for establishing a good communication in Mizoram was also felt by the Government which finally led to the existence of MPRO in the year 1972 under the supervision of one head designated as SP(PHQ).

After Mizoram became UT in 1972, some of the Assam Police personnel were inducted into Mizoram Police thereby paving the way for the induction of APRO staff into MPRO. In the same year, the Government of Mizoram created 24 various posts in Police Wireless vide order No. HMP-4/72/PT-1/87 Dt.29.3.1972 which were filled up deputation and by direct recruitment. Since then, MPRO personnel who were recruited/absorbed from APRO were compelled to work immediately ignoring either Police Basic Training or Technical Training due to insurgency in the State.

In the year 1973, about 4 SI’s and 19 operators were recruited and were directly sent to the Technical Training Institute either at CPRTI New Delhi or at UP Radio Organization, Mahanapur, Lucknow without undergoing Police Basic Training which is a must for every newly recruited Policeman. After completion of their training course, they were sent to various PR stations and it is very unfortunate to learn that most of these MPRO staff had never a chance to undergo Police Basic Training.

But after a decade in 1983, a short course for a period of 3 months basic training course was held at PHQ Aizawl and about 20 MPRO personnel attended the course successfully. It has been felt that the duration of basic training period for MPRO staff is too short in comparison to nine months course spent by other Police personnel but this could not be achieved due shortage of Manpower in the unit till order was passed by IGP Mizoram vide Letter No. E/PHQ/18/93/78. Dt.25.2.93. However, because of the long experience of the unit, most of the MPRO staff were trained for a period of three months only till 1997.

Meanwhile Pu P.C Lallianthanga joined MPRO as direct Dy.S.P (C) on 10.4.92. He and 2 senior Officers namely Pu K. Lalchhunga IGP(M) and Pu C. Khenglawt DIG(Admn) thoughtfully decided that the Officers of MPRO should undergo normal Basic Training Course like the Officers of other units and also to perform District Practical Training during their probation periods. Further, in addition to this, the officer after completion of his probation period will have to undergo technical familiarization course for a period of 4 months either at APRO Assam or CPRTI New Delhi.

Now, the newly appointed officers of this unit have been undergoing Basic Training at NEPA as per the desire of the authority. As expected, it has been noticed that the discipline of the staff who performed Basic Training at NEPA is far superior in comparison to the discipline of the staff who performed only three months Basic Training course. The practical training during probation period is found to be of great value as the officers have familiarized all the works of different units. Moreover, a time may come when the officers will have to co-ordinate with all sections of Police force.

In MPRO, after completion of Basic Training as per the recruitment rules, one has to pass grade examination to enable him to get promoted to next higher rank. Grade examination is for various trade viz:- Operating, Fitter, Cipher and Radio Mechanic(RM). Grade-II and grade-III examinations for operator have been held in MPRO since 1983 till date.

TRAINING SCHOOL: MPRO Training School was established in the year 1983 and was inaugurated by S.P Ganguly SP(W) at MPRO HQRS Aizawl. As a new school was established, the expenditure for sending  MPRO Staff outside Mizoram for training had decreased drastically. The school is mainly oriented towards modern communication system and discipline, it also teaches fundamentals of technical subjects such as Physics, Mathematics, Electronics etc. in addition to subjects related to communication. Besides theory papers, practicals are also essential for certain subjects and one has to possess a considerable standard of knowledge theoretically and practically in order to get through the examinations.

The training school also provides an opportunity to persons who are interested in reading by maintaining a library. The staff and trainees of the unit now have ample chance to enrich their knowledge in various subjects by making use of the library rather than wasting their free time.

The MPRO training school has four regular indoor instructors and one outdoor instructor. During office hours, the trainees attend indoor classes as  a preparation for the said grade examination and they attend PT and parade on every Monday and Thursday early in the morning to develop their physical fitness. A periodic inspection is also held regularly in the classroom to ensure that the turn-out of each and every trainees is satisfactory.

For most of the final examinations held, supplementary examinations are conducted for the unsuccessful candidates and many candidates have made use of the supplementary examinations.

MPRO is proud of its regular instructors who dedicated all their valuable times and efforts in moulding and upgrading the status of the trainees of the MPRO and for being able to conduct a number of grade examinations and also for helping the trainees in bringing out fruitful results in their exams.

In the current session, the 4th batch PWO-I and 18th batch PWO-III course is in progress and the final examination is likely to be held in the month of December 2011.

In the beginning, the School was established at Headquarter Aizawl. But due to the increase in the number of staff and trainees, it was too congested and was then shifted to Durtlang.
