Patch panels are not required for cabling a network. They fulfill the function of centralizing connections in an area, and allow for easy movement of workstations from network to network. In a wiring closet you may find many different connections that have to be connected from a router to the workstations on the floor. With a patch panel you can connect multiple systems from a wiring closet using horizontal wiring to the work areas very easily. This makes it easier to create wired networks but it is not absolutely required.
The wiring that connects workstations to the closest telecommunications closet is typically done using structured cabling, such as Ethernet cabling (Cat5e, Cat6, etc.). These cables are run from each workstation to the patch panel in the telecommunications closet, where they are connected to the network switch. This setup allows for a centralized and organized network connection for each workstation within the building.

AV on wiring diagrams for construction refers to "audio-visual", i.e., sound and video cabling and accessories.
A hub uses straight throught cabling from clients to the hub, and uses a cross-over cable with the up-link ports to connect hubs to hubs. Usually, the cabling is UTP (Unshielded Twisted Pair) wiring.
Horizontal cabling is the cabling that connects the work area telecommunications room to the horizontal cross connect.
Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems. Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications using various kinds of cable, most commonly category 5e (CAT5e), category 6 (CAT6), and fiber optic cabling and modular connectors.
The most common type of wiring found in houses is non-metallic sheathed cable, known as NM or Romex. It consists of a plastic-coated sheath enclosing insulated wires that carry electrical current throughout the building. NM cable is easy to install and provides a safe and reliable means of wiring a house.
Range Extenders are used as part of a wireless network. When placed inside the range of the main wireless router, the extender will bounce the signal, without the need for any additional network wiring.

90 Meters+ 10 meters for running cables so 100 meters is the total.
