In order for the user to develop rightly the new network services that are offered to him, he must initially select the technology that he will use basing it on his needs. Factors such as the speed of transmission, the biggest distance of connection, the cost of installation and operation will play a decisive role in his choice.

The broadband technologies that the user has in hand are :

Optical Fibre Networks

Depending on where the optical fibre terminates we have the following cases:

• FTTH (Fiber to the Home): The optical fibre reaches the final user
• FTTB (Fiber to the Building): The optical fibre reaches the building, while in it the interconnection continues with crosswired copper pairs.
• FTTC (Fiber to the Curb): The optical fibre reaches up to the KAFAO and then the connection continuous with copper wires.
  

xDSL Network Technologies

In this case we have a big team of different technologies (ADSL, G.lite, RADSL,VDSL, SDSL, SHDSL, HDSL, HDSL-2 και IDSL). For the transmission of data we use the digital subscribing Lines.

The most well known standards being the IEEE 802.11 (Wi-Fi) and IEEE 802.16 (Wi-Max)

Constant Wireless Access technology (LMDS)

Satellite Broadband Access

At the municipality of Ialysos and during the realisation of the invitation 84 a network of broadband services is forecasted to be installed which will connect the City hall of Ialysos, the Citizens Advice Bureau and the new Bioclimatic  High School. The network will be constituted from a wired technology connection ΑDSL and two wireless trunke connections (table 1). Also in two from the three points (the CAB and the Bioclimatic high School of Ialysos) will be created Hot Spots Wi-Fi 802.11g that will provide access to the broadband services with speeds of up to and 54Mbps. Both of these technologies of Broadband Access (ΑDSL και ΙΕΕΕ 802.11) for their better understanding we will analyse them in the entities to follow.
