s problemati

cUplink limited link budgets and throughput

Other propr ietary f ixed systems have output power up to 2 watts &directional antennas

Signif icant benef it of additional uplink power for f ixed applications

Additional sub carr iers for more throughput

Higher modulation modes

Network capture vs maintain sessions at cell edge
