Wireless broadband access is a crucial part of any carrier and enterprise network. It has been a big argument among expertise which type of technology should be leveraged to fulfill the business needs. They argue which of the broadband technology is the best fit to propose solution and based on which criteria the right technology should be selected. In this paper we have elaborated on five key technologies...
Predictions abound on the growth of mobile data traffic driven by smart phones and tablet PCs that come with an expectation of broadband Internet connectivity everywhere and a demand for high quality video. The FCC's National Broadband Plan indicated that mobile data traffic in North America would increase by roughly 20 to 45 times between 2009 and 2014, and current data suggests these numbers may...
Spurred by the increasing demand for mobile broadband services and the growing number of devices supporting multiple radio access technologies (e.g., cellular, WiMAX, Wi-Fi, Bluetooth), much research is being done to improve the user experience while addressing issues related to network efficiency, congestion, interference, and cost to operators, service providers, manufacturers, and consumers alike...
Nowadays networks are characterized by the abundance of diverse Radio Access Interfaces (RAI) in the same operating area. The various wireless interfaces can belong to the same Radio Access Technology or not. In such a scenario, a mobile user will be able to select selfishly one of the available radio interfaces in order to enhance its own performance. Therefore, the radio access selection policy...
This paper describes an approach for providing wireless broadband access in urban areas by deploying the cognitive radio technology operating in geographically unused TV bands. It is shown, through system simulations performed for real-life urban settings, that a wireless network equivalent to that of cellular operators' next generation mobile broadband (based, e.g., on HSPA or LTE) can be rolled...
The telecommunications infrastructure citizen-oriented has become a necessity in cities that wish to direct themselves to a new information society. One of the technological alternatives for these infrastructures is municipal wireless networks. These municipal wireless networks offer flexibility, speed of installation and less implementation costs for cities. For this reason, it is considered of interest...
Wireless network operators often offer wireless broadband services by using different wireless technologies such as WiMAX, WiFi and HSPA. Each wireless technology often uses a separate and stand alone network architecture, and thus operations and management may easily become a complex and expensive task. In this paper we present the design and implementation of an all-IP heterogeneous network where...
Wireless broadband and metro Wi-Fi are sweeping through municipalities, campuses, enterprises and public safety organizations creating a buzz of excitement and anticipation unseen in the communications arena since the advent of the Internet. In this networking landscape mesh networks are emerging as the wireless technology of choice, offering a cost-effective solution for providing low cost, reliable...
Providing users of multi-interface devices the ability to roam between different access networks is becoming a key requirement for service providers. The availability of multiple mobile broadband access technologies together with increasing use of real time multimedia applications is creating strong demand for handover solutions that can seamlessly and securely transfer user sessions across different...
With the maturation and acceptance of broadband wireless technology and standards (e.g. mobile WiMAX, EVDO, HSPA), forward-looking service providers are beginning to augment their coverage with new broadband wireless networks and offering new higher-speed services. At the same time, we see that on-the-go transit and ride-sharing vehicles are beginning to see a market for offering wireless access throughout...
In the recent years, wireless mesh network (WMN) has evolved as a new paradigm for broadband wireless Internet access. The self-configurability, open wireless infrastructure, and different management styles of WMN make them vulnerable to malicious attackers. As a first step to secure WMNs, it is critical to incorporate an authentication mechanism for mesh clients. The existing proposals are primarily...
Support for mobile workers is an important component of an enterprise's overall IT infrastructure. The rapid evolutions in both wireless broadband and handheld device technologies demand a set of guidelines that provide maximum user benefit while maintaining a manageable support model. This article describes what to consider when evaluating handheld devices for corporate standardization.
