FIGURE 7. PanOULU network architecture (5, p. 4) The “CITY” comprises of two types of WLAN zones. They are a campus and five public organizations: Oulu University, City of Oulu, <strong>OUAS</strong>, Heli ry (Hen- gitysliitto, i.e. Pulmonary Association), VTT (Valtion Teknillinen Tutkimus- keskus, i.e. Technical Research Centre of Finland) and the panOulu sub- scriptions sold by ISPs (DNA Oy, Elisa Oyj, Netplaza Oy and LAN&WAN) (22). ISP (Internet Service Provider) (27) is a product, which allows any or- ganization to acquire panOULU hotspot, mobile APs and network without any additional client software. The “REGION” subnet is comprised of eight nearby municipalities. The municipalities allow the locations of the WLAN-zones consisting of 1200 access points (APs). They provide both indoor and outdoor coverage in places deemed relevant for a public access. The coverage is provided with a WLAN mesh network in the city center and the surroundings, otherwise in a hotspot manner. (5, p. 4.) PanOULU offer in its authentication area the wireless wideband Inter- net-connection for every willing citizen. PanOULU WLAN system includes devices such as open WLAN base stations (WLAN radio), antennas, server SMS, (Short Message Service), logs and routers. The services are SMS messaging, IRC (Internet Relay Chat), news, GPRS (General Packet Radio Service) map service. PanOULU net- 18
work needs a WLAN (based on the IEEE 802.11s standard) compatible PC, handheld computer or mobile phone. The part of the base station network is a mesh-network. It is a type of network where each node must not only cap- ture and disseminate its own data, but also serve as a relay for other sensor nodes and must collaborate to propagate the data in the network. An example of mesh-network is the Internet (Figure 8). FIGURE 8. mesh-network (9; 23; 24) Mesh-network is based on the SLAP-base stations (Street Level Access points) that make a network and search the best connection straight to RAP- base stations (Root Access points). The RAP-base stations have a fixed net- connection but SLAP-base stations do not. Another part of the base stations are WLAN-type networks. PanOULU WLAN is working in healthcare centres and libraries only in the countryside near Oulu. The structure of panOULU WSN-network (Wireless Sensor Network) (Figure 9) includes sensors, APs (Access Point) (same as base stations) and GSN- server (Global Sensor Network) working with clients on the Internet. 19
