ADSL Broadband is ideal for email and internet usage, however if you are considering collaborative features that are bandwidth hungry then you should really consider Superfast Broadband.
Small, Medium Enterprises considering cloud-based products or video conferencing should consider Superfast Broadband, FTTC & FTTP will offer higher speeds than ADSL connectivity, FTTP being complete Fibre will deliver the fastest results
Fibre-to-the-Cabinet involves running fibre optic cables from the exchange to the street cabinets which then connect to a standard phone line to provide broadband. FTTC is combined with a copper cable from the cabinet which can deliver much faster speeds.
Fibre-to-the-Premises also referred to as Fibre-to-the-Home (FTTH) provides and end-to-end fibre optic connection, the full distance from the exchange to your premises and so delivering faster connectivity than FTTC as there is no copper within the infrastructure.
