What are the advantages and disadvantages of Ad Hoc WLAN and Infrastructure WLAN ?
369820
Ad Hoc is cheaper as it does not need a router. But infrastructure is much better for sharing things between 3 computers or more, because each computer only needs one network connection if there are 3 units, instead of 1 to connect each pair of computers. So, if you have 2 computers, ad hoc is better and if you have 3 or more infrastruvture is better. SSID and ESSID are security systems for protecting unauthorized users to use the network.

WLAN is used in many situations and companies.\nYou should try in supply chain area, were logistics use PDA's to get info and send to their ERP's. \nSAP WM has a standard solution and you can get cases from www.sap.com. \n\nAnother interesting example is more as a commodity than strategy. WIFI in metting rooms, during SW migrations/upgrades when several consultants arrive and WIFI is a quickiest and low cost way to deplace and insert all this temporary people wihtin your LAN

no hassle of tangled cables\nlow maintenance cost\nless baggage to carry\nand above all......... no need to hide any connections when u r hacking

A wireless LAN or WLAN is a wireless local area network that uses radio waves as its carrier: the last link with the users is wireless, to give a network connection to all users in the surrounding area. Areas may range from a single room to an entire campus. The backbone network usually uses cables, with one or more wireless access points connecting the wireless users to the wired network.

Wireless g is a protocol the Wi-Fi uses.\n\nCheck out http://en.wikipedia.org/wiki/WiFi for more.

I would suggest picking up a wireless router. you could do an ad-hoc network but if you want to share the internet connection, your best bet is to use a small router. for about $50 dollars you can pick up a Linksys WRT54G and have all your bases covered.   ofcouse you'll need wireless network cards for each of the computers. the documentation with the linksys router will guide you through the process. also check out some info on wireless security. (see sources)

They have the same range.  WPA and WEP are types of encryption and do not have a bearing on the actual output or transmission power associated with them.\n\nWPA is much more secure than WEP, just for your info.

you should be able to disable the windows wlan control through control panel if you really want

I agree with the first answer.\n\nyou have to consider:\n-topography of location (is the area surrounded by mountains, or is the location a 'free-space' type?)\n-type of network to be built (wired or wireless?)\n-distances of endpoints (if you're opting for wireless)\n\nfor your reference:

802.11b is a global standard (a rare thing indeed!). Therefore with a multi-lateral roaming platform in place WiFi has the potential to become the de-facto standard for international remote-access wireless data services and utlimately, with VoIP, for voice too.\n\nI have 802.11b built in to my note book and do not have to have anything else except a WiFi area.\n\nthe letter after 802.11 is for the later upgraded editions.

I would suggest a solution of Wireless LAN Bridging (WiFi) ... It would be very effective in 1 Km distance it would give throughput of 24-36 Mbps which is quite enough for most applications. check Cisco, D-Link , and USrobotics devices and solutions.

This depends entirely upon the system you have, what OS it runs, and whether or not you are using the software included with your device, or those built into your OS.  It also makes a difference whether you are trying to set up an ad-hoc network, or connect to an existing network that may be passworded

Not bad, but Linksys and Dlink are generally better for routers.  Most routers have the same features these days so there is not a huge difference in practice.  Where I have found the most issues is on the wireless client side, as some interfaces, like US wifi clients, just will not work properly on some PCs.

I presume you refer to the mobile ad-hoc network (MANET).\nMANET is a self-configuring network of mobile routers (and associated hosts) connected by wireless links—the union of which form an arbitrary topology. The routers are free to move randomly and organise themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. Such a network may operate in a standalone fashion, or may be connected to the larger Internet. Minimal configuration and quick deployment make ad hoc networks suitable for emergency situations like natural or human-induced disasters, military conflicts, emergency medical situations etc.\n\nMANET is extremely vulnerable to malicious node presence and to certain types of attacks that can occur. To address these concerns, several secure routing protocols have been proposed recently: SAODV, Ariadne, SEAD, CSER , SRP, SAAR, BSAR, and SBRP.\n\nIf you are talking specifically about WiFi connections as it relates to "ad hoc" as opposed to "infrastructure". In the case of "infrastructure" WiFi network, there is a specific "hub" or access point (AP) is predefined to act as the central connecting point. In case of "ad hoc", the WiFi device can connect to any and all other WiFi systems at will.\n\nThere are advantages of ad hoc WiFi, but without pre-set and shared security the ad hoc infrastructure is exposed to anyone malicious or not to connect. By it's nature, ad hoc WiFi mode allows others to initiate connections to your system without much security.

Security! \n\nSecurity should be a big part of any presentation concerning wireless connectivity.\n\nAdditionaly you could discuss its uses (RFID, networking, etc...)\nCost\nInfrastructure comparison to wired connectivity\nAccess

Surely you cant compare\n\nWLAN is a type of network not restricted to one geographical area, an example of it is the Internet as well as 3G (but more focused on mobile/cell phones).\n\nPDA is a type of a handheld computer, so what ways can you say WLAN has an advantage over PDA and vice versa?
