It has lowest cost and good range of signal which cannot be easily obstructed
. It has a major problem of like the home appliance can obstruct the frequency of the bandwidth
b. IEEE 802.11a
. It was found in the year of 1999 with the frequency of 5GHz and the maximum speed of 54Mbps, with the range of 100ft in indoor and 450ft outdoor
. This standard has the 12 non-overlapping channel in which it has 8 point for indoor and 4 point to point
. the problem in this is that it has highest cost and a shorter range of signal which can be easily obstructed
c. IEEE 802.11g – Data rates 54Mbps in the 2.4 GHz or 5 .It was found in the year of 2003 with the frequency of 2.4GHz and the maximum speed of 54Mbps and the range of 125ft . It has a good signal and cannot be obstructed easily and has the fastest maximum speed. . It will cost more than 802.11b
d. IEEE 802.11n
. It was found in the year of 2009 with the frequency of 2.4/5GHz with the speed of 600Mbps and a range of 225ft indoor and 825ft outdoor
. It has the fastest maximum speed and the are signal range which is more resistance from the outside.

ManageEngine Desktop Central is prone to a security-bypass vulnerability related to the password-reset feature. An attacker can exploit this to reset the application’s administrator password and gain administrative privileges. On 27 March 2015, a proof of concept (PoC) exploit code was released on multiple websites such as Seclist.org and PacketStormSecurity.com. Open source research did not reveal any instances of this vulnerability in the wild. However, this does not mean that malicious actors…

From my reference materials from Cisco and previous work history, I firmly believe that the #1 issue surrounding the deployment of a wireless network is wireless security. Specifically, passive monitoring, unauthorized access, and DoS attacks. Passive Monitoring – wireless networks are intentionally designed to propagate data throughout buildings and areas, almost always resulting in the radio signals traveling beyond the limits of the area. By default, wireless devices are configured for maximum…
