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.
