Performance of I-HSPA vs Fixed Wireless
I-HSPA is similar to HSPA+, the 3GPP Rel 7 version of HSDPA/HSUPA of 3GPP Rel 5.
It is an overlay on the 3G/W-CDMA/UMTS mobile phone system and as such is designed for short term mobile connections.
The technology is limited by designing for battery operation and best effort to make a voice call.
It is an afterthought to an existing mobile Voice system, the 2G USA CDMA-one.
LTE (FWA) is not an I-HSPA upgrade but a different system.
Fixed Wireless systems (FWA) are not based on technology for Mobile Phone calls.
Its designed entirely for Broadband delivery without phone wires, coax cable or fibre.
Power and Aerials are not constrained by portability.
Mobile networks are much more expensive than Fixed Wireless Networks.
Mobile Masts are often sited to facilitate mobile voice calls rather than Fixed Computer usage.
This document concentrates on comparing speeds
For simplicity a single sector cell is shown. Real masts typically have three sectors, which uses three times the spectrum but gives three times the capacity per mast/Cell.
