What is HSPA?

HSPA supports increased peak data rates of up to 14 Mbit/s in the downlink and 5.8 Mbit/s in the uplink. It also reduces latency and provides up to five times more system capacity in the downlink and up to twice as much system capacity in the uplink, reducing the production cost per bit compared to original WCDMA protocols. HSPA increases peak data rates and capacity in several ways:

  • Shared-channel transmission, which results in efficient use of available code and power resources in WCDMA
  • A shorter Transmission Time Interval (TTI), which reduces round-trip time and improves the tracking of fast channel variations
  • Link adaptation, which maximizes channel usage and enables the base station to operate close to maximum cell power
  • Fast scheduling, which prioritizes users with the most favorable channel conditions
  • Fast retransmission and soft-combining, which further increase capacity
  • 16QAM (Quadrature Amplitude Modulation), which yields higher bit-rates

HSPA has been commercially deployed by over 200 operators in more than 80 countries.

Sender Policy Framework…need to know about how to protect the Mail spam

If you have not already done so, I highly recommend you create an SPF record for your domain as this will make it much more difficult for spammers to forge your domain in order to spam domains in other organizations.

Sender Policy Framework..WikiPedia Definition

Creating your own SPF record is a relatively simple process, Microsoft even provides a web-based GUI wizard that will help you do this.. Domain holders need to complete an inventory and publish all IP addresses of their outbound email servers in the DNS zone file. This is an administrative step that requires no changes to an organizations email or DNS software. Even if your domain has no outbound email servers, you can help protect your domain from spoofing by publishing an SPF record in the DNS that states this. Microsoft Safety Home Page click here
