The 3G Networks 101
Posted by admin | Posted in 3G | Posted on 09-07-2009
There are several networks available when using various types of 3G
accessories and gadgets. You have to consider the details and different
data speeds, to understand and know if you are getting enough for your
money. You can learn more about networks by visiting their respective web
sites or companies. You should know which brands are leading and which ones
still need some improvement. Here are some more details.
Turn Key 3G Network
No network vendor can provide all components and equipment to the full 3G
network. There are a limited number of individuals considered as a main
contractor to create a turn-key 3G network. Normally, network vendors can
bring partners like applications providers and service, civil work, handset
manufacturers and acquisition industries.
The current short list of major vendors for the UMTS networks considered as
turn-key are Alcatel, Lucent, Ericsson, Motorola, Nokia, Nortel and NEC or
Siemens. The present short list of main vendors for CDMA2000 networks
categorized as turn-key include LG Electronics, Lucent, Ericsson, Motorola,
Samsung and Nortel.
Costs of the Network
A 3G network can be built for a certain price. You can get more information
by reading annual reports and contract announcements. These will indicate
the sum of money that operators will spend on buildings and infrastructure.
In each nation, a carrier will need to spend about the same costs to create
a 3G network of the same size. All operators generally spend the same
amount of money for every subscriber.
Spending details will include services such as integration, logistics,
planning, commissioning, testing and many more. Press reports present that
operators in Europe spend about 650 euro for every 3G subscriber for site
civil works, infrastructure and planning services. The figure are expected
to get lower in a few years. There are several other fees to consider also,
like licensing.
Ensuring Safety
On electromagnetic radiation safety, you have to go to the latest
government EMR or standard or electromagnetic radiation. You may also check
and review the government web site. The government pages should contain
more data and information. You can get a booklet that provides guidelines
including details like, the safety zone around the transmission and mobile
antennas, local guidelines on the location of the antenna, the combined
radiation field values computed from various antennas on a single rooftop,
how the EMR computations are made and power levels of interior antennas.
More on EMR
The government frequently do not indicate the right values that are safe or
unsafe, for legitimate reasons. EU nations usually issue a number of steps
or guidelines that are considered quite rough compared to the standards
given by the EU. The American FDA has a clear statement too. There are more
than 700 studies and tests related to EMR without a real known outcome. You
should consider the risks and potential threats associated with the
continuous development of the 3G technology, and others more powerful than
it.
Base Stations
There are many factors to consider, to check if base stations are required
for a network for UMTS. Some inclusions are financial support for the
network build, economical factor to create sites, required coverage areas
related to a license agreement, design preferences of company experience to
implement the provided plan, coverage requirement for clients and amount of
frequencies that the available carriers have.
