the authentication is done with the hostapd daemon. If the client has a static IP-adress you will need no DHCP-server. As the DNS-server use the same server as the fedora-computer. Enable ip_forwarding with
echo "1" > /proc/sys/net/ipv4/ip_forward
bring the wlan up with the desired IP-adress (which then also is the gateway for the clients)
ifconfig wlan0 192.168.1.1 up
ptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
(if the Computer has an internet-connection at eth0).
Then start hostapd (it's a daemon, take a look at the documentation for Fedora). Be sure to have the correct /etc/hostapd/hostapd.conf file, but there are several explanations in the internet.
