Your Work Area
The department Access Network Technology, which is a part of the business unit Communication Technologies, provides consultancy, develops tools and gives independent advice on using fixed and wireless access network technologies. Our main focus in wireless technologies includes radio spectrum management, radio resource management, radio planning, optimization and measurement for UMTS/HSPA (3G), (Mobile) WiMAX, Long-term evolution (LTE), etc. Our expertises results in technical innovations and are for example used by departments of the government, operators (e.g. KPN) and the industry.
The classical approach for wireless network operators is to have exclusive use of the wireless network resources such as spectrum, sites, transmission lines, core networks, etc. Only site sharing, driven by the lack of site locations and environmental aspects, has been widely adopted as form of ‘resource sharing’. However, recent developments show further expansion towards the concept of ‘resource sharing’ i.e. wider network infrastructure sharing and, as expected in the future, spectrum sharing. Future spectrum sharing can be expected due to the 3GPP specifications of multi-carrier options in advanced wireless access systems (e.g. HSPA+, LTE-Advanced) and the fragmented spectrum bands owned by different operators.
The drivers to expand the area of ‘physical resource sharing’ can be cost-oriented (e.g. lower CAPEX and OPEX), customer-oriented (e.g. higher capacity, coverage, end-user quality), regulatory (e.g. satisfying licensing agreements), environmental (e.g. reduced number of sites, power consumption), etc. This concept of physical resource sharing is presented in Figure 1.
