The difference between EVDO and HSDPA




EVDO (Evolution Data Optimized) is a third-generation mobile broadband technology of 3G CDMA networks operating in and capable of providing higher data speeds of 2 Mbps in a mobile environment. CDMA EV-DO comprised of three major standards as specified by 3GPP2 as part of the CDMA 2000 standard. 


While HSPA (High Speed ​​Packet Access) is the terminology used to refer to the HSDPA (3GPP Release 5) and HSUPA (3GPP Release 6), based on 3.5 G GSM technology and has a much higher speed than 3G and GPRS. Theoretically, HSPA compaction speed can go up to 14.4 Mbps downlink and 5.8 Mbps uplink, 3-4 times faster than 3G downlink speed and 15 times higher than GPRS. But the network is currently only able to deliver 3.6 Mbps downlink and 500 kbps for uplink. 
Broadly speaking, the difference EVDO and HSPA are:
  • Bandwidth CDMA radio interface used is 1.25 MHz while utilizing HSPA bandwidth of 5 MHz.
  • Data rates for speed EVDO speed is 14.7 Mbps HSPA 14.4 Mbps while.
  • Standards developed by the networks CDMA EVDO and HSPA 3G network is considered as 3.5 G.
