Wireless communication taken analogically simply refers to the channel of telephony communication that does not apply the use of wires (Bose, 2010) . Such a channel makes use of electromagnetic waves available in the atmosphere (Bose, 2010) . Wireless communication employs the transmission of voice and or data within a defined channel and a set frequency bandwidth (Bose, 2010) . Wireless communication is able to have an extensive coverage from a small geographical location and possibly able to reach a global scale depending on the specific technology put in use (Bose, 2010) . These technologies are able to grant the consumer with flexibility to roam even globally and yet remain connected to broadband services (Bose, 2010) . Luckily, these warless communication technologies are able to integrate multiple services such as data and voice within a singular network (Bose, 2010) . This study aims to analyze some of the wireless technologies applied today in the commercial mobile telephony platform and outline some of the positive and negative attributes. Specifically, the study shall concentrate on the discussions centered on 3G, 4G, WWAN, and WIAMX wireless cellular technologies.
The third generation in cellular technology popular shortened as 3G is the subsequent mobile or wireless telephony technology that successes the 1 st and the 2 nd generation (1G and 2G) of the 1980’s and 1990’s respectively. In essence, 3G is faster than its two predecessors offering packet-switched data at a greater speed more efficiently. 3G sufficiently and efficiently offer multimedia applications supports in mobile telephony. The need for increased working speeds also necessitated the rise of the 4G or fourth generation technology. With data rates of up to 100 Mbps, 4G offers the fastest data rates possible for a wireless cellular technology. The ability of such data speeds makes it possible for organizations to include as part of their communication channels such options as IP-based voice and even online streaming of media (Pereira & Sousa, 2004) . In other words, first, 3G and 4G cellular technologies advantageously are able to offer broadband capabilities when the end user is on the go and are not hindered by the traditional fixed telephone (Pereira & Sousa, 2004) . Secondly, they thus enable an end user to access broadband anywhere around the globe and thus make worldwide roaming possible while still connected to broadband services (Pereira & Sousa, 2004) . Luckily, 4G cellular technology also offers a consumer seamless handoff between base stations (Pereira & Sousa, 2004) . That is to say, 4G is able to offer a consumer with seamless connection to multiple networks that are able to achieve greater speeds at the same time within a given locality. Thirdly, 3G and 4G cellular technologies are able to offer a platform with expandable bandwidth hence is able to overcome the limitations of bandwidth limits (Pereira & Sousa, 2004) . In other words, these technologies are very flexible thus granting endless possibilities (Hanzo, Haas, Imre, O'Brien, Rupp, & Gyongyosi, 2012) . Finally, both 3G and 4G offers room for upgrade and as a result with time may provide a path for even better, more subtle and more powerful cellular technologies (Pereira & Sousa, 2004) . Mobile telephony technologies are very dynamic and ever changing. One of the key disadvantages is that the frequent upgrades are resource intensive and thus the costs of such upgrades are very high. Unfortunately, the billing structure may not be clear to both the client and the service provider (Pereira & Sousa, 2004) . As such may lead to exploitation especially of the client by the service provider (Pereira & Sousa, 2004) .
Delegate your assignment to our experts and they will do the rest.
An organization planning to diversify its channels of intra-organizational and inter-organizational communication are at the advantage of using 3G, 4G, WWAN, and WIAMX to facilitate real time information exchange between internal and external stakeholders. Such communication channels include communication channels such options as IP-based voice and even online streaming of media (Pereira & Sousa, 2004) . Real time communication is thus able to improve business information exchange and promote business growth.
Worldwide Interoperability for Microwave Access (WiMAX) is a system of interoperable wireless broadband able to offer clear outdoor signals. However, when compared to 4G, its data rates are quite slower and speed together with the associated costs will more often than not depend on how far the access point is from the transmitter. WiMAX operates on a fixed access approach (Hanzo et al., 2012). Therefore, even the geographical area covered may also not be wide and as such may not be able to offer a worldwide coverage like 3G and 4G. The design of the WiMAX system is entrenched to the stationery user and as such not applicable for a worldwide roaming consumer (Hanzo et al., 2012).
Wireless Wide Area Network (WWAN) on the other hand is a mobile telephony technology that is able to connect different geographical localities and thus possibly cover a wide geographical space (Wei & Gitlin, 2004) . Therefore, consumers can keep communication with other consumers sited in other base stations different from theirs (Wei & Gitlin, 2004) . In this case, the consumer does not bear the costs f\of roaming between other networks as this is taken care of by the client’s service provider.
In general, depending on the given particular need that a consumer may have preference of either of the above technologies may vary from one consumer to another. For example, a client who wants to be connected to broadband services anytime and anywhere around the globe would definitely prefer a technology, which is able to offer him or her roaming capabilities. In such a scenario, 4G wireless cellular technology would be the most appropriate technology of choice since the customer is not only granted roaming possibilities but is able to do so seamlessly and still with far greater data rates per unit time.
As a way of enhancing service provision to its customers and for the customers to enjoy an improved user experience of the internet through their phones, wireless communication organizations and their users have been using wireless application protocol (WAP). However, WAP invokes serious security concerns and as such, this study opposes its application because of these security weaknesses. Primarily the application of WAP and especially through the WAP gateway does not guarantee end–to–end security (Wei & Gitlin, 2004) . The passage of unencrypted data through the WAP gateway can pose security threats especially considering the fact that vendors of the WAP gateway may not be keen at monitoring such information as often as required (Wei & Gitlin, 2004) . In other words, as much as the WAP is a good tool for mobile internet use experience, it can be highly compromised.
In summary, technology and including wireless mobile telephony is improving human lifestyle and livelihood. Wireless cellular technology is improving how human beings are able to communicate with each other especially if set apart by distance. However, in the midst of such applications, the flaws and weaknesses of such technology can also compromise human safety if not looked into carefully.
