what are the most challenges of wireless networks? Explain in detail

Solution

there are several challenges faced in wireless network today some of them are::

1.security

2.connectivity issues

3.power and energy

security: Mobility of users increases the security concerns in a wireless network. Current wireless networks employ authentication and data encryption techniques on the air interface to provide security to its users. The IEEE 801.11 standard describes wired equivalent privacy (WEP) that defines a method to authenticate users and encrypt data between the PC card and the wireless LAN access point. In large enterprises, an IP network level security solution could ensure that the corporate network and proprietary data are safe

connectivity issues::

addressed this issue in various ways, such as adding access points, segmenting networks to maintain appropriate access, limiting the bandwidth of their guest network and implementing management and policy software. Participants said connectivity issues also arise from the addition of applications to the network that operate in a proprietary environment. Some ways to address this issue include working with vendors to either move away from the use of proprietary solutions or to upgrade to an environment that accepts multiple versions of 802.11 standards.

power and energy::

A mobile device is generally handy, small in size, and dedicated to perform a certain set of functions; its power source may not be able to deliver power as much as the one installed in a fixed device.When a device is allowed to move freely, it would generally be hard to receive a continuous supply of power. To conserve energy, a mobile device should be able to operate in an effective and efficient manner.
