19. Technology
 The 4G technology is characterized according to the standard certification profiles
defined by either WiMAX Forum (WiMAX) or 3GPP (LTE). In detail the following
parameters are specified:
• Frequency
• Channel bandwidth
• Duplexing format
• Modulation and coding scheme
• SNIR
 Custom profiles can be defined to completely customize the use of the 4G technology
in terms of:
• Frequency
• Channel bandwidth
• Duplexing format
19

20. Equipment
 In order to perform the link budget analysis, equipments (BTS/eNodeB and user
equipments) are characterized in terms of :
• Antenna gain
• Cable losses
• Feeder losses
• Transmit power
• Noise figure
• LNA gain
• Penetration loss
• Body loss
• Number of sectors
• Number of antenna elements in transmission and reception
20

21. Performance
 The maximum path loss on the basis of a relevant number of parameters:
• Equipment characterization (BTS/eNodeB and user equipment)
• Margins
 Cell edge coverage probability, lognormal shadowing standard deviation, fast fading margin,
interference margin (in down and up link)
 The coverage predictions of the median path loss related to each scenario are
calculated on the basis of the selected path loss model (Cost-231, SUI, ECC-33, Log-
normal with/without shadowing, Free Space)
 The capacity provided by each BTS/eNodeB is evaluated on the basis of:
• Supported MCS
• Distribution of MCS
• Number of carrier per sector
• Number of sectors per BTS/eNodeB
21

22. Capacity demand
 To evaluate the feasibility of the services to be offered and to perform the dimensioning
of the network infrastructure correctly, the capacity demand is estimated
 The capacity demand denotes the capacity required in down and up link by the users
located in each area to be served and it is estimated depending on relevant parameters:
• Market forecast

• Number of radio links per each technology (SDH, PDH, IP Ethernet, etc.)
• Number of ASN-GW (WiMAX) or MME, S-GW, P-GW (LTE)
 This network dimensioning is performed by taking into account:
• Coverage requirements
• Cell overlapping factor
• Characterization of ASN-GW/EPC
• Percentage of BTS/eNodeB with wireless backhaul and multihop factor
• Distribution of radio links among the various technologies (SDH, PDH, IP Ethernet, etc.)
• Legacy network (existing BTS/eNodeB and radio links)
23

24. Roll-out
 The network roll-out is evaluated on the basis of the roll-out function, that
denotes the percentage of year-on-year deployed infrastructure.
 The annual bill of quantities is estimated in terms of:

• Logical sectors
• Radio links
• ASN-GW / MME, S-GW, P-GW
