<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>
