"There are two definitions for wireless LAN roaming:
Internal Roaming (1): The Mobile Station (MS) moves from one access point (AP) to another AP within a home network because the signal strength is too weak. An authentication server (RADIUS) performs the re-authentication of MS via 802.1x (e.g. with PEAP). The billing of QoS is in the home network. A Mobile Station roaming from one access point to another often interrupts the flow of data among the Mobile Station and an application connected to the network. The Mobile Station, for instance, periodically monitors the presence of alternative access points (ones that will provide a better connection). At some point, based on proprietary mechanisms, the Mobile Station decides to re-associate with an access point having a stronger wireless signal. The Mobile Station, however, may lose a connection with an access point before associating with another access point. In order to provide reliable connections with applications, the Mobile Station must generally include software that provides session persistence.
External Roaming (2): The MS (client) moves into a WLAN of another Wireless Internet Service Provider (WISP) and takes their services (Hotspot). The user can independently of his home network use another foreign network, if this is open for visitors. There must be special authentication and billing systems for mobile services in a foreign network." [Wireless LAN. Wikipedia]

Cisco Network Templates

Cisco has a huge number of enterprise clients in the corporate environment. Therefore many network engineers should draw network diagrams for Cisco hardware.
ConceptDraw has Cisco network diagram templates:

Wireless Mesh Network, Network Organization Chart, Roaming Wireless Local Area Network, Cisco ISG Topology Diagram, Cisco Express Forwarding Sample that facilitates drawing at the initial stage.

However for customizing Cisco network diagrams you can use 13 Libraries like this: Cisco Basic, Cisco Buildings, Cisco IBM, Cisco LAN, Cisco WAN, Cisco Media, Cisco Optical, Cisco People, Cisco Routers, Cisco Security, Cisco Switches&Hub, Cisco Telepresences, etc.

This take great advantage to you for designing Cisco network diagram templates.
"A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. Ethernet over twisted pair cabling, and Wi-Fi are the two most common technology standards currently used to build LANs." [Local area network. Wikipedia]

"The ideal telecommunication network has the following characteristics: broadband, multi-media, multi-point, multi-rate and economical implementation for a diversity of services (multi-services). The Broadband Integrated Services Digital Network (B-ISDN) intended to provide these characteristics. Asynchronous Transfer Mode (ATM) was promoted as a target technology for meeting these requirements" [Broadband networks. Wikipedia]
"Wireless broadband is technology that provides high-speed wireless Internet access or computer networking access over a wide area. ...
Wireless networks can feature data rates roughly equivalent to some wired networks, such as that of asymmetric digital subscriber line (ADSL) or a cable modem. Wireless networks can also be symmetrical, meaning the same rate in both directions (downstream and upstream), which is most commonly associated with fixed wireless networks. A fixed wireless network link is a stationary terrestrial wireless connection, which can support higher data rates for the same power as mobile or satellite systems.
Few wireless Internet service providers (WISPs) provide download speeds of over 100 Mbit/ s; most broadband wireless access (BWA) services are estimated to have a range of 50 km (31 mi) from a tower. Technologies used include LMDS and MMDS, as well as heavy use of the ISM bands and one particular access technology was standardized by IEEE 802.16, with products known as WiMAX."

This wireless network diagram sample illustrates mobile data offloading.
"Mobile data offloading is the use of complementary network technologies for delivering data originally targeted for cellular networks. Rules triggering the mobile offloading action can be set by either an end-user (mobile subscriber) or an operator. The code operating on the rules resides in an end-user device, in a server, or is divided between the two. End users do data offloading for data service cost control and the availability of higher bandwidth. Operators do it to ease congestion of cellular networks. The main complementary network technologies used for mobile data offloading are Wi-Fi, femtocell and Integrated Mobile Broadcast." [Mobile data offloading. Wikipedia]

"A wireless network is any type of computer network that uses wireless data connections for connecting network nodes. Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks." [Wireless network. Wikipedia]
