WIFI, 3G and 4G networks are rapidly changing how the public
uses the internet. The Cisco Certified Network Associate with Wireless
course trains information technology professionals to operate Cisco’s
equipment, which serves the general public when accessing a wireless
server. This article contains basic information about the job duties
information technology professionals will perform after passing the CCNA
Wireless certification exam.
Clients are an essential part of wireless networks. They
require a specific section in CCNA Wireless because not all clients are the
same. Wireless clients are differentiated by three types of characteristics:
•Wi-Fi client adapter: Most devices produced today come with
built-in wireless adapters. Older devices can be outfitted with an external
wireless networking card. Different cards might have different physical
characteristics and capabilities.
•Wireless client software: Client software, such as the
Intel ProSet, AirPort Extreme for MAC, Windows AutoConfig Service, Apple iOS,
and Google Android, can be configured for the client to associate with an AP.
Different software applications can have different feature sets and different
supports for the underlying physical card capabilities.
•Client security settings: There are several possible
security configurations to achieve wireless security. Some clients support only
some security types, thus limiting the type of wireless network you can join.
Most clients enable you to associate to a detected network
(broadcasted SSID) or configure a specific profile. In all cases, you must
configure the network name (SSID), the operating mode (ad-hoc or
infrastructure), and some security settings (that will be different depending
on whether the SSID uses Pre-Shared Key Security or Enterprise [EAP/802.1x]
security). The way each of these three items is configured (sequence, menu
names, configuration possibilities) varies from one client to the next.
ABCO Technology’s Cisco Wireless course is a full hands-on
class that prepares you to function in the wireless internet environment.
