DISCUSSION 1:

In an RF WLAN, data can be sent in one of two connection modes: ad hoc mode and infrastructure mode. Ad hoc mode is commonly known as peer-to-peer mode, and in this type of WLAN two or more computer systems can communicate directly with each other. Its formal name in the 802.11 standard is Independent Basic Service Set (IBSS) (Olenewa, 2014). This mode is useful for a quick and easy setup of a wireless network anywhere that a network infrastructure does not already exist (Olenewa, 2014). However, the drawback is that the wireless clients can only communicate among themselves and do not have access to an internal wired network.

On the other hand, the second wireless network mode is the infrastructure mode, which is also known as the Basic Service Set (BSS). Infrastructure mode consists of at least one wireless client connected to a single Wireless Access Point (WAP). When this type of network is expanded and more than one WAP is used, the network evolves from a BSS to an Extended Service Set (ESS). In an ESS both WAPs use the same Service Set IDentifier (SSID) to remain on the same network and provide users with uninterrupted wireless access. A drawback of ESS WLANs is that all wireless clients and APs must be part of the same network for users to be able to roam freely between one AP and the other (Olenewa, 2014).

DISCUSSION 2:

Surprisingly there are only two types of WLAN modes which are Ad Hoc mode and Infrastructure mode. Starting off with Ad Hoc, this mode communication is made between devices wirelessly without the need to use an access point. According to Olenewa (2014), Ad Hoc is known by peer-to-peer mode with having its formal name of Independent Basic Service Set (IBSS) using 802.11 guidelines. Syncing up RF, devices can transmit and receive data with ease quickly. People would mainly use this mode when an internet connection doesn’t exist in an area and data needs to be transferred quickly. The one drawback is devices can only connect with each other transferring data and can not connect to a wireless network to collect data that isn’t already on one of the devices. The second mode of WLAN communication is Infrastructure Mode. This type is basically one device connected to an access point. It is also known as a Basic Service Set (BSS) .To get it to work, there can be multiple devices connected with a wired connection but there can also be devices that are connected wirelessly. The devices don’t connect to each other like Ad Hoc but use an access point instead to transfer data. If one AP is not enough, there can be multiple AP using the same SSID which turns the service into an Extended Service Set (ESS). ESS is a way to connect devices by making the reach of Access points wider by making zones. The drawbacks of using infrastructure mode is security, having a network connection already installed, and the range the connection has.
