Radio Communication
Radio communication mainly engages the business such as radio
network planning, network optimization, project design and technology
consulting, etc, whose business scope covers the mobile communication,
trunking communication, radio paging, satellite communication,
radio AN, and microwave communication, etc.
The radio communication specialized profession of SPTDIC enjoys
a solid technical strength, which has accumulated rich project
experience in the fields of mobile communication, microwave
communication and satellite communication. It is also one of
the earliest units to embark on the mobile communication project
design in China. During the last decade, it has successively
undertaken a great many of project design works of the managers
such as China Telecom, China Mobile and China Unicom, etc.,
including the major works of microwave level-1 trunk, simulate
TACS/GSM/CDMA mobile communication project. What's more, it
was also in charge of the high-tech communication construction
works for many times, such as the multisystem-combined indoor
coverage system of Shanghai Pudong International Airport, Shanghai
F1 International Racing Field, etc; It has independently accomplished
the academic researches of the tasks ,such as the radio transmission
model correction under the typical topography, CDMA network
high architectures' pilot pollution ,introduction of CDMA network
inside the subway and interference analysis between different
systems.
SPTDIC has attended the entire process of the construction and
testing work of Ministry of Information Industry Shanghai 3G
Test Network, and also has made the all-round follow-up and
study in the aspects of the planning , design and technology
system, etc. of 3G network , which all make the company accumulate
some precious practical experience. SPTDIC also develops the
research on the tasks of 3G transmission model, business model,
coverage forecast, PN and scramble planning, radio interworking
structure, etc and has already got the preliminary achievements.
The radio communication specialized profession of SPTDIC has
advanced design tools and refined equipment. At present, SPTDIC
is equipped with the advanced mobile communication network planning
simulation system and optimized tools among the industry, such
as Wizard, Planet, Airport, etc. so that this company is capable
of making planning and research on the networks of TACS, GSM,GPRS,
CDMA, CDMA1X, WCDMA, CDMA2000, TD-SCDMA, iDEN, TETRA. SPTDIC
has also independently developed the applicable software such
as mobile network optimization management system, etc. In addition,
this company is also equipped with the complete testing meters
and instruments, including testing tools for mobile communication
network, field intensity tester, spectrum analyzer, microwave
field intensity tester, transmission model correction testing
equipment, etc.
