The 3G Networks 101
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.
