Choosing the Right Access Point for Different Environments

This article discusses the best access point options for different environments such as hospitals, universities, and offices. It explains the advantages and considerations for each environment, including factors like network traffic, frequency compatibility, speed, range, and cost.

NETWORKING

1. General Hospital
We will be using 802.11g access point. The other AP mostly used in areas where there is
large network traffic especially the universities where the number of users are so many. This
access Point cover long distances and have maximum speed of about 54Mb/s. The network
that have 802.11g work at the radio frequency of 2.4 Ghz. This bandwidth specification has
(OFDM) modulation that makes the AP, obtain higher data speed. Computers and end
devices that are connected to this kind of AP can fall up to a minimum speed of 11Mb/s. This
feature makes it compatible with 802.11b NICs, and 802.11n NICs devices that can be
connected in the network .This APs have a wider range, this means that there network
frequencies cover a wider area since they can penetrate through walls than 5ghz which
cannot (Jordan & Abdallah, 2012). Although this property makes them to have a low speed
but they are the best to be implemented in this case. Another reason is that 802.11N have
higher frequency. High frequency signals cannot penetrate through walls hence some areas of
the hospital may not be able to have Wi-Fi when this kind of APs are used. Though most of
devices have 2.4 frequency, several APS of 802.11g will have to be mounted in different
locations of the hospital in order to increase the frequency of the network in each corner of
the hospital. Another advantage is that the APs are cheaper hence easily affordable. When
this APs are implemented in the hospital the network flow will run smoothly since there will
be no traffic in the network due to crowd users. This is because in hospitals the number of
users is less.

2. Central university.
We will be using 802.11n access point since the university has a many number of users who may
cause network traffic in other APs. This is because the access point supports both 2.4 GHz AND
5GHz bands, and supports numerous concurrent information streams between the end users and
the AP. These can also referred “Spatial streams” .They use the available multipath to multiplex
i.e-sending data to different destinations (Zhang, Ansari & Tsunoda, 2010). Both bandwidths 2.4
GHz and 5.0 GHz are required in the AP because they have different properties that are required
in the network to be implemented in the university. 802.11n supports an upwards of 200 to 600
Mb/s throughput depending on the number of the data streams that are available in the network.
With the 2.4GHz bandwidth, the network will cover a wide range hence reaching a wide number
of users in the university.
802.11n has high speed since it has both the two bandwidths. This means that the 5GHz will be
used in video streaming by the students within the floor. The uploading and downloading speed
of this bandwidth is a bit higher. This can also be used in making of video calls due to its high
speed. While 2.4 GHz has low speed which can be used in offices that require browsing of light
files in the university. Furthermore, the range of the AP is also to be considered, since it has both
the frequencies it will have a wide area of coverage that is required by the university. It connects
to laptops and desktops of all Wifi and network standards. Lastly the interference of frequencies
from 802.11n is little (Doefexi, Armour, Lee, Nix, & Bull, 2013) .This is because the 2.4 GHz
bandwidth has 11 channels that end devices uses when connected to the network while 5 Ghz has
23 channels and because few devices support this property of the Aps there will be minimal
interference of the wireless network frequencies thus high network speed. Also the 2.4 Ghz
penetrates through walls and flows of the building hence reaching and covering a wide area.
Thus 802.11n will be the best standard of the AP that will be connected to the switch since it has
severally properties that fit the requirements that are supposed to be added in the existing
network.
