What are the advantages and disadvantages of a Wireless LAN?

Wireless LANs have advantages and disadvantages when compared with
wired LANs. A wireless LAN will make it simple to add or move 
workstations, and to install access points to provide connectivity in areas
where it is difficult to lay cable. Temporary or semi-permanent buildings
that are in range of an access point can be wirelessly connected to a LAN to
give these buildings connectivity. Where computer labs are used in students,
the computers (laptops) could be put on a mobile cart and wheeled from
classroom to classroom, providing they are in range of access points. Wired
network points would be needed for each of the access points.
A WLAN has some specific advantages:
 It is easier to add or move workstations
 It is easier to provide connectivity in areas where it is difficult to lay
 Installation can be fast and easy and can eliminate the need to pull
cable through walls and ceilings
 Access to the network can be from anywhere in the school within
range of an access point
 Portable or semi-permanent buildings can be connected using a
wireless LAN
 Where laptops are used, the ‘computer suite’ can be moved from
classroom to classroom on mobile carts
 While the initial investment required for wireless LAN hardware can
be similar to the cost of wired LAN hardware, installation expenses
can be significantly lower
 Where a school is located on more than one site (such as on two sides
of a road), it is possible with directional antennae, to avoid digging
trenches under roads to connect the sites
 In historic buildings where traditional cabling would compromise the
façade, a wireless LAN can avoid drilling holes in walls
 Long-term cost benefits can be found in dynamic environments
requiring frequent moves and changes
 They allows the possibility of individual pupil allocation of wireless
devices that move around the school with the pupil.
