This diagram depicts enterprise private network (EPN) using frame-relay and dial-up.
"An enterprise private network is a computer network built by a business to interconnect its various company sites (such as production sites, offices and shops) in order to share computer resources." [Enterprise private network. Wikipedia]
"Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a dialed connection to an Internet service provider (ISP) via telephone lines. The user's computer or router uses an attached modem to encode and decode Internet Protocol packets and control information into and from analogue audio frequency signals, respectively. Dial-up internet is sometimes used where Broadband internet access is not available; primarily in rural or remote areas." [Dial-up Internet access. Wikipedia]
The example "Enterprise private network" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"A cable television headend is a master facility for receiving television signals for processing and distribution over a CATV system. The headend facility is normally unstaffed and surrounded by some type of security fencing and is typically a building or large shed housing electronic equipment used to receive and re-transmit video over the local cable infrastructure. One can also find head ends in power line communication (PLC) substations and Internet communications networks." [Cable television headend. Wikipedia]

This circle-spoke diagram sample illustrates the proximity marketing.
"Proximity marketing is the localized wireless distribution of advertising content associated with a particular place. Transmissions can be received by individuals in that location who wish to receive them and have the necessary equipment to do so.
Distribution may be via a traditional localized broadcast, or more commonly is specifically targeted to devices known to be in a particular area.
The location of a device may be determined by:
(1) A cellular phone being in a particular cell.
(2) A Bluetooth or WiFi device being within range of a transmitter.
(3) An Internet enabled device with GPS enabling it to request localized content from Internet servers.
(4) A NFC enabled phone can read a RFID chip on a product or media and launch localized content from internet servers.
Communications may be further targeted to specific groups within a given location, for example content in tourist hot spots may only be distributed to devices registered outside the local area.
Communications may be both time and place specific, e.g. content at a conference venue may depend on the event in progress.
Uses of proximity marketing include distribution of media at concerts, information (weblinks on local facilities), gaming and social applications, and advertising." [Proximity marketing. Wikipedia]
