From a practical stand point, the role of WMO can be
classified into following two major categories:


Social and economic dimensions
Regulatory dimension
[For the sake of accuracy, it is noted that the social and
economic dimensions follow from regulatory framework of
spectrum management. ]
Lakhs of crores invested in commercial mobile, satellite
and broadcasting services and the dependence of tens of
crores of population on them require that these services
be free from radio-interference, which may arise from a
multitude of reasons.
From an alternative viewpoint, radio frequency spectrum
has two properties just as any natural resource has. These
properties are: the quantity and the quality. The quantity
aspect of the spectrum is primarily the domain of WPC
Wing, whereas the quality aspect of the spectrum is
essentially the responsibility of the WMO.
The role of the WMO in respect of regulatory aspects of
spectrum management essentially derives from the Preamble of
the Radio Regulations of the ITU.
The Preamble contains, inter alia, the following:
0.5 With a view to fulfilling the purposes of the International
Telecommunication Union set out in Article 1 of the
Constitution, these Regulations have the following objectives:
0.6 to facilitate equitable access to and rational use of the
natural resources of the radio-frequency spectrum and the
geostationary-satellite orbit;
0.7 to ensure the availability and protection from harmful
interference of the frequencies provided for distress and safety
purposes;
0.8 to assist in the prevention and resolution of cases of harmful
interference between the radio services of different
administrations;
0.9 to facilitate the efficient and effective operation of all
radiocommunication services;
0.10 to provide for and, where necessary, regulate new
applications of radio-communication technology.
Based on the regulatory aspects of ITU, WMO’s
focus areas are




To ensure compliance by all wireless networks which
employ the state-of-art technologies;
To more intensively monitor the spectrum to find unutilized
and / or under utilized spectrum;
To introduce new parameters of measurement across
multitudes of applications of about 40 generic radio
communication services.
To provide interference-free communication to all
authorized licensees.
The challenge to the WMO is to ensure interferencefree communications which is perhaps unique in the
world. This challenge arises from the enormous size of
networks, variety of technologies and ever growing
applications of radio techniques.
An effective radio monitoring service, unlike providing,
say, mobile communication service, does require a
deeper understanding of technology involved in radio
interface of networks. This essentially entails building
professionalism/ competence indigenously in the art
and science of radio monitoring, as the same cannot be
imported.
Constraints not withstanding, WMO has taken a few
major steps to tackle the most serious of challenges,
notably those concerning mobile communications and
broadcasting services.
Taking into account of these, all new proposed
procurements of equipments are particularly focused
on resolving interference to cellular and broadcasting
networks.
WMO has developed and using an in-house
design of radio monitoring database.
WMO has proposed upgradation of existing Wireless
Monitoring facilities and also to procure the new latest
wireless equipments under the 12th Five Year Plan with
an outlay of Rs 500 crore.
WMO has been allocated Rs 50 crore during the
current FY for the same.



Resolved almost all the interference cases of cellular
services except where the interference is being
observed across the border. In most of the cases
interference is being observed by the boosters and
jammers.
Localized the radiation on the emergency frequency
emitted by the Aircraft , unintentionally.
Resolved the problem of interference during the VIP
movements at IGI Airport and also suggested the
wayout.


WMO has set-up a dedicated temporary Control Station at
Monitoring headquarters New Delhi during the Common
Wealth Games in 2010, for constant round the monitoring.
The interference reported during the Common Wealth
Games by the wireless service providers was resolved with
the hours.
Interference reported by the Russian Administration was
also resolved.
