U900 & Spectrum Refarming WS : U900 benefits and refarming best practicies (introduction) | Commercial in confidence | 2013-04-18 | Page 4Source: Ericsson estimates, based on rough assumption

U900 Estimated Challenge

Since Number of frequencies have reduced in GSM an increase in traffic can result in more load on frequencies

Tight frequency plan has to be executed for maintaining network quality

UL RSSI can be a main factor which can increase on u900 implementations due to:-

traffic activities on adjacent gsm band channels without guard band between u900 and g900Due to better propagation characteristics of u900 compared to u2100

Physical optimization of different technology with same antenna will also be a challenge

Frequency load on G900

High RTWP on U900
