All the communications between stations will go through AP. Access point is like a router. As mentioned all the stations e. It converts protocol from wireless Here all the stations or clients receive the packet but the client whose address matches with the destination field will decode and process the received packet. Compared to ad hoc wireless networks, infrastructure mode offers the advantages of scale, centralized security management, and improved reach.
Wireless devices can connect to resources on a wired local area network LAN , which is common in business settings. More access points can be added to improve congestion and broaden the network's reach. The disadvantage of infrastructure mode wireless networks is the additional cost of AP hardware. Ad hoc networks connect to devices in a peer-to-peer P2P manner, so only the devices themselves are needed.
No access points or routers are necessary for two or more devices to connect to each other. In short, infrastructure mode is typical for long-lasting or permanent implementations of a network. Homes, schools, and businesses do not usually use the P2P connections used in ad hoc mode because they're too decentralized to make sense in those situations.
Ad hoc networks usually exist in short-lived moments in which some devices need to share files but are too far from a network to work. A small operating room in a hospital might configure an ad hoc network for some wireless devices to communicate with each other, but they're all still disconnected from that network, and the files are inaccessible.
If just a few devices need to communicate with each other, however, an ad hoc network will work fine. One limitation of ad hoc networks is that, at some point, the hardware won't be able to accommodate the traffic. That makes infrastructure mode necessary. In this case, it would be ideal if you know what kind of network connection you can use. Moreover, a lot of devices that are Wi-Fi-enabled are only capable of connecting to infrastructure-mode networks—not to ad-hoc ones.
So, what is the difference between infrastructure and ad-hoc wireless networks? In this article, we will discuss that. Here is a quick run-down of the topics we will discuss:.
Most people are familiar with Wi-Fi networks functioning in infrastructure mode. Basically, when devices are connected on this network, they communicate through a single access point, which, in general, is the wireless router.
They can be connected to the same wireless network, but they are not directly communicating with each other. What happens is, one device sends packets to the access point and the packets are sent to the other laptop.
In this type of wireless network, the devices can connect directly to each other. For instance, you are inside a hotel room without Wi-Fi and you want to directly connect two laptops to each other.
You can do so by forming a temporary Wi-Fi network through ad-hoc mode.

Oct 17, Wireless networking offers some obvious convenience over its wired counterparts, such as Ethernet networks and those that work over the telephone or via electrical wiring in your house.
However, wireless networking also has some drawbacks. It's a good idea to know a little about the pros and cons before you start your network. This chapter is from the book.
