In this project you will be using Cisco Packet Tracer to configure a wireless network that includes three LANs; a cellular LAN; a Wireless LAN; and a Wired LAN with a wireless router.$$ The system will be a $4$G$/5$G architecture with VoIP capability and data transfer.$$ Each of the three interconnected networks will be accessed through a Gateway$/$NAT router with IPv$4$ static public IP addresses externally and private IPv$4$ access internally.$$ The access points should be interconnected and each LAN will have its own DHCP server for internal $($private$)$ IPv$4$ addressing.$$ Run a simulation to demonstrate the functionality of your network by sending both voice and data information.$$ The mobile devices have the capability of a smart phone which means that they can communicate with the access point using either voice or data.$$

Add security aspects to your network and explain how to emulate a secure network in packet tracer for each of the LANs. Keep in mind that security can be different for each of the types of LANs.$$ When you add security, ensure that you$$ provide a few sentences in your paper describing your approach and how and what type security you added.$$

LAN $1$ is a cellular configuration. The Gateway router can also be configured to support the NAT.$$ The central office server supports DHCP for the internal LAN.$$ All gateway routers connect via a serial link and use IPv$4$ public IP addresses which can be set as a static address.$$ The IPv$4$ public addresses should be $172\mathrm{.}0\mathrm{.}10\mathrm{.}1$; $172\mathrm{.}0\mathrm{.}20\mathrm{.}1$; and, $172\mathrm{.}0\mathrm{.}30\mathrm{.}1,$ for LAN$1,$ LAN$2,$ and LAN$3,$ respectively.

LAN $2$ is a wireless configuration. Each device is connected to an access point through a wireless network.$$ This is a basic service set architecture, so there are no ad hoc wireless connections between devices.$$ This networked system can use a single router connection between the access points and the Internet.$$ However, between the access points and the router$/$gateway$,$ install a switch and a network address translation $($NAT$)$ to convert IPv$4$ private addressing structured network to IPv$4$ public structured addressing for transfer into the Internet via the router$/$gateway$.$ The Smartphone devices must support both data and voice.$$ You will need to use smartphone devices for the wireless connectivity because straight VoIP phones in Cisco do not support wireless; only PCs and smartphones. All of the internal network addressing is to be done by DHCP$.$Incorporate WiFi security into your network.

LAN $3$ is a wired system that has a wireless router. Connect the three VoIP phones in series with the three computers.$$ The three laptops are connected via the wireless router.$$ Segregate the wireless router and the wired system phones$/$PCs using a switch.$$ The internal IPv$4$ addresses need to be assigned via DHCP$,$ however, the public IPv$4$ protocols are static. $$You will need a vlan.$$

Run simulations that show connectivity among all the devices for the transfer of both voice and data. The architecture needs to include at least two servers that demonstrate the client$/$server exchange process for data.

Run a simulation that shows the path for a VoIP phone call from a device within each of the networks to a device in each of the other networks. Run simulations that show and data voice connectivity among the LAN $1,$ LAN $2,$ and LAN $3$ networks $.$
