Wireless Network Limitations – Disadvantages – Drawbacks

Wireless network technologies are either ad hoc or can be based on an infrastructure. Ad hoc wireless network is connected through any specific infrastructure or any central device operating for it like router. The wireless connections which operate via the use of solid infrastructure are equally faster but less expensive. Another type of wireless connections is called WAP or wireless access point.

On a commercial level many WAP (Wireless Access Point)s are wrapped tighter and are connected to provide wireless signals to commercial areas. There is a major difference between ad hoc wireless connection and WAP (Wireless Access Point). WAP (Wireless Access Point) is a device which allows other wireless devices to connect and transfer signals. Ad hoc systems do not require any central point for operation. AD hoc systems are used for when a wireless signals are needed for smaller geographical area. Adhoc systems provide very fast transfer of data because they are faster than WAP (Wireless Access Point).

Security in Wireless Network Connections

Ad-hoc wireless network signals are not really strong as compared to the wireless connection which uses routers to function properly. Wireless networks incur high cost but are really easy to implant. However the actual challenge comes when we try to secure its signals. Insecure wireless network can be attacked by hackers. Wireless connections are not preferred to the banks and other sensitive departments. Where loss of information means loss of everything. Wireless signals are easy to catch as compared to wired signals. For the safety of reliable transfer of data, still the experts prefer wired connections.

Other Limitations to Wireless Networks

When the wireless signals are transferred they are blocked by the certain obstacles as walls, gates and human beings. The strength of wireless signals depends upon the location; if you’re closer to infrastructure you receive signals. For example if a wireless infrastructure is established in any university campus. Students spread throughout the campus can not access the signals because the strength of signals varies from location to location. In short whole university campus cannot be benefited from the single wireless connection. Wireless signals can be hindered by other electronic devices, the rate of frequency and the height from the ground. The fear of the unauthorized users is the biggest concern for people transferring sensitive information. The reason is that if your wireless internet connection is not secured using internet any unauthorized user can exploit the signals or even hack important information. The use of ad hoc wire less technology requires the use of very expensive personal digital devices or PDAs like black berry, palmtops, laptops and smart phones. The recent up gradation of wireless technologies also require you to improve your knowledge about how to make use of any wireless technology. Though wireless technology is very common but still it is an expensive way of remain connected. Wireless network is relatively less stable and efficient than a wired connection. It operates on the rule, the nearer the faster. Initial setup is complicated. Wireless connection requires the set up of stations. Stations are those transmission mediums which help the wireless system to operate.

Cost associated with wireless network

The cost of establishing wireless network can also be termed as one of its limitations. Any 802.11g router can approximately be an expense of about $25 to $125. Laptop card or PCI card can cost up to $50 to $150. This is not it one may also consider the additional costs associated with wireless connection. For example additional cost of connecting a router to DSL modem. If the router connected to the DSL operates at a distance of 100 meters away then an additional router is attached to receive the signals. The cost of managing and upgrading the wireless network can not be neglected at all.
