    15 by extending the <xref href="GUID-BBF6E33F-2E9C-5BB1-8404-87289EC73BFF.dita">multimode

    16 telephony</xref> API and the <xref href="GUID-8F565241-149E-5AF7-972E-A06B6DDC1B9F.dita">packet

    17 data telephony</xref> API. HSUPA is defined in 3GPP R6 specifications. </p> <p>HSUPA

    18 provides users with a high speed uplink, which allows network operators to

    19 provide more interactive value-added data services. HSUPA improves data throughput

    20 and reduces delays by using technologies such as adaptive modulation and hybrid

    21 ARQ. The main advantages of using HSUPA is that it does not require any hardware

    22 modifications to existing network and phones that already supports 3G. </p> <p>Developers

    23 who wish to use HSUPA functionality should include <filepath>etelmm.dll</filepath><i/> and <filepath>etelpckt.dll</filepath> in

    24 their MMP files. </p> </section>
