<section id="GUID-0FFFAB4D-AEE9-4DC8-89AF-45D3EB39926E"><title>Introduction</title> <p> The HSUPA functionality is supported
by extending the <xref href="GUID-BBF6E33F-2E9C-5BB1-8404-87289EC73BFF.dita">multimode
telephony</xref> API and the <xref href="GUID-8F565241-149E-5AF7-972E-A06B6DDC1B9F.dita">packet
data telephony</xref> API. HSUPA is defined in 3GPP R6 specifications. </p> <p>HSUPA
provides users with a high speed uplink, which allows network operators to
provide more interactive value-added data services. HSUPA improves data throughput
and reduces delays by using technologies such as adaptive modulation and hybrid
ARQ. The main advantages of using HSUPA is that it does not require any hardware
modifications to existing network and phones that already supports 3G. </p> <p>Developers
who wish to use HSUPA functionality should include <filepath>etelmm.dll</filepath><i/> and <filepath>etelpckt.dll</filepath> in
their MMP files. </p> </section>
