Operators and Internet service providers invest in broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use Adsl, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for Adsl with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of Adsl, the important quality parameters and how to gather them from the available services today.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are Adsl, G.lite, Adsl2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Sveaverken is a company who manufactures products and equipment for the modern farm enterprise within grain, pork and horse businesses. A large share of Sveaverken's turnover depends on the role as a subcontractor for Delaval within the areas ventilation, manure handling and feeding systems. Sveaverken wants to investigate the possibility to increase sales by establishing new sales channels, for example e-commerce This thesis is an analysis of the Swedish farmers use of internet, attitudes towards e-commerce and Sveaverken's interest within this area. There is also a minor economic analysis of the cost of establishing the e-commerce site. The study focuses on farmers who are potential customers to Sveaverken within Sweden. To examine the farmers opinions about internet and e-commerce a questionnaire was developed and sent out in November 2006, to 500 farmers of which 45% answered. The results show that the average age of the farmers was 42,5 years.

Till att börja med studerades vad bredband är samt vilka tjänster och aktörer som finns. Ett antal frågor ställdes till utvalda aktörer för att reda ut vad de erbjuder gällande tjänster, bandbredd, säkerhet mm. Sedan beskrivs några olika uppkopplingsmöjligheter: LAN, Adsl samt Kabel-TV, samt kort om vad framtiden kommer att erbjuda. För att ta reda på hur bredbandet används så valde vi tre grupper som vi intervjuade om deras bredbandsanvändande. Detta gjordes för att få en överblick om hur man använder bredband och vilka säkerhetsåtgärder man tagit som privatperson.
