Scenario (1): Evacuating 20 Mhz out of the existing band for the Lte indoor installation will have the following outputs; Severe high degradation on the existing GSM NW as the DCS1800Mhz is carrying the majority of the traffic in the GSM NW (preferred band in traffic sharing with P-GSM & E-GSM) Keeping in mind that the degradation shown in previous slides was only for 5Mhz band evacuation.
Scenario (2): Evacuating only 10 Mhz to be used in Lte indoor installation will have the following Output; The existing indoor Infra-structure for Etisalat supports only SISO and hence the Capacity will be divided by ~ 2 & as the spectrum goes down from 20Mhz to 10 Mhz will again divide the Lte Capacity by ~ 2 resulting in Over all Cell capacity ~ 33 Mbps which is less than the HSPA+ (dual carrier 42Mbps).
