“…Figure 3.1 shows the different geographical locations considered in this study, which embrace a wide variety of scenarios including indoor (location 2) and outdoor environments at high points (location 1), narrow streets (locations 3-7), between buildings (locations [8][9][10] and in open areas (locations [11][12]. The considered measurement locations represent various physical scenarios of practical interest that embrace a wide range of receiving conditions and levels of radio propagation blocking, ranging from direct line of sight to severely blocked and faded signals.…”

“…The current spectrum underutilization has motivated an important number of activities and initiatives in the regulatory [6][7][8][9][10][11][12], economic [13][14][15][16][17] and research communities in searching for better spectrum management policies. In this context, the term Dynamic Spectrum Access (DSA) has been coined to refer to innovative solutions proposing a procedure or scheme to share spectrum among wireless operators, technologies and services in order to increase the overall spectrum utilization.…”

“…The measurement locations considered in this study embrace a rich diversity of practical scenarios in urban and sub-urban areas. The scenarios analyzed in urban areas are illustrated in Figure 3.1 and include various locations within the Campus Nord of Universitat Politèc-nica de Catalunya (UPC) in urban Barcelona, not only outdoor high points (location 1), but also indoor environments (location 2) as well as outdoor locations at the ground level in narrow streets (locations 3-7), between buildings (locations [8][9][10] and in open areas (locations [11][12]. For outdoor high point measurements (location 1), the equipment was placed in the rooftop of the three-floor building belonging to the Department of Signal Theory and Communications of UPC (latitude: 41 • 23' 20" North; longitude: 2 • 6' 43" East; altitude: 175 meters).…”

“…After initializing the counters and variables employed in the measurement process (lines 3-7), the script then waits until the time for beginning the measurement session is reached (lines [8][9][10]. When the start time is reached, the measurement process begins and it is performed repeatedly until the specified stop time is reached (lines [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Every cycle consists in the realization of one sweep and its storage.…”

“…A new variable (line 8) is used to store the start time for the next sweep cycle and control the exact time instant at which a new sweep cycle is initiated. Before a new sweep cycle is started, the control script remains idle waiting for the next_sweep_time instant (lines [10][11][12]. When the next_sweep_time instant is reached, a new sweep is then initiated and the time instant for the next sweep is updated (line 14) according to the specified T_sweep.…”

BoxTo my beloved family for their unconditional love and support.A mi querida familia por su cariño y apoyo incondicionales. 0 ABSTRACTThe owned spectrum allocation policy, in use since the early days of modern radio communications, has been proven to effectively control interference among radio communication systems and simplify the design of hardware for use at a known and fixed range of frequencies. However, the overwhelming proliferation of new operators, innovative services and wireless technologies during the last years has resulted, under this static regulatory regime, in the depletion of all spectrum bands with commercially attractive radio propagation characteristics. The vast majority of spectrum regarded as usable has already been allocated, thus...
