WLAN TECHNOLOGY

Introduction

Virtualization, cloud computing, and wireless technologies are fundamentally changing enterprise computing, providing revolutionary gains in productivity and cost savings. Powerful enterprise WiFi applications can now be delivered to almost any device, anywhere, at any time and take advantage to enterprise.

In-store Mobility Solution

  • Mobile applications in retail are not new. Over the years, barcode scanning enabled mobile applications in the retail storefront, in the back room and in warehouse locations that have helped retailers reduce operating costs by improving productivity and providing greater supply chain visibility. Mobile applications such as inventory tracking, shelving, labeling, etc. started as competitive differentiators and now have become an integral part of how retailers conduct business. Leading retailers have even used in-store mobility technologies to improve the sell-side of their business with customer-facing applications and store manager applications to foster a better in-store experience.

  • The rapid rate of evolution in mobility technology and elevated concerns regarding credit card data security, are bringing about a new phase in retail mobility with a brand new set of challenges and opportunities. The most urgent and compelling issue that retail IT faces today is to keep existing applications running. Aging mobility infrastructure and, more importantly, legacy investments in mobile devices are no longer supportable. Add to that recent compliance mandates and it is clear that retail IT has a major overhaul of its mobility infrastructure in sight. The good news is that the costs of making such changes can be easily contained by choosing the right IT strategy and the right in-store mobility infrastructure.


Secure Wi-Fi For Healthcare Applications

  • Most healthcare organizations have existing WLAN access points, many originally installed several years ago, offering one or two services to clinicians, employees or guests. Recent advances in Wi-Fi technology and enterprise WLAN functionality make it possible now to deploy all major healthcare IT services over a single, unified WLAN. Multi-purpose Medical Mobility (MMM) networks can provide comprehensive network-edge connectivity with full communication reliability and end-to-end Quality of Service.


The WLAN In The Hospitality Industry

  • WLAN technology can help hospitality venues create differentiated services that reduce operational expenses, improve customer satisfaction, increase brand value and drive the growth of revenue. Business and leisure travelers now view Wi-Fi connectivity as a necessity, one that influences their choice of lodging.

  • WLAN systems for the hospitality industry must be capable of supporting critical internal applications (e.g. VoWLAN, check-in, room audit) and providing guests with connectivity on a single network while maintaining complete separation between internal and hotspot traffic. The sensitive nature of credit card Point of Sale/check-in transactions and gaming applications requires that IT managers institute policies that vigorously guard against the interception of data. VoWLAN demands the ability to support end-to- end QoS, Call Admission Control, and fast inter-AP/inter-subnet mobility. Deployment of the “centralized” WLAN architecture, with “thin” APs managed by a controller, is the best way to support hospitality applications while ensuring network security.


Enhance Learning For Primary School

  • Backpacks overloaded with outdated textbooks and crumpled worksheets are becoming a thing of the past.

  • Students delight in learning through games, having real-time chats with experts, and exploring the world through virtual field trips. With digital learning, students stay engaged and learn faster. Teachers can tailor lessons to students’ individual education needs, provide one-on-one help, and easily measure progress. Many K-12 school districts have already embraced one-to-one computing initiatives, in which students have their own laptops. Many other districts are exploring the budget-friendly bring-your- own-device (BYOD) course, in which students use their own laptops and tablets in the classroom. Regardless of the method to equip students, digital learning leads to an explosion of laptops, tablets and other mobile devices in the schools.


Bring-Your-Own-Device (BYOD) Solution

  • Today’s growing demand for anytime, anywhere network access to enterprise resources has expanded to include the use personal mobile devices such as laptops, tablets, smartphones, e-readers and more.

  • From the executive who purchased an iPhone to boost personal productivity to the college professor who re-designed his curriculum to take advantage of new tablet-based education applications, users in all types of organizations are bringing a myriad of consumer devices to work. And when they do, they expect access to business applications and content, not just the Internet.

  • In response to this consumerization of IT, many organizations are allowing employees to choose their laptops and use their own smartphones and tablets at work in support of bring-your-own-device (BYOD) initiatives. While organizations may still require access to confidential resources via a company-owned device, they are creating more flexible policies that also allow access via personally-owned devices.

  • As a result, the number of devices per employee is growing from a one-to-one relationship to a one-to-many relationship. A single user today will interchangeably connect to the network using a laptop, smartphone and tablet throughout the day.
    The benefits to organizations that embrace BYOD initiatives include the ability to quickly respond to user needs, boost user productivity, and in many cases, reduce expenses.


High-Quality Voice Over WLAN Solution

  • The reliable delivery of latency-sensitive voice and video streams mandates the use of transport mechanisms with very low packet loss, jitter, and delay. IP PBX systems already incorporate the necessary mechanisms to deliver these services over local area networks (LANs) and wide area networks (WANs). The introduction of corporate Wi-Fi networks and wireless clients introduces a disruptive new variable in the transportation of latency-sensitive streams, one that must be properly managed and controlled to provide a satisfactory user experience.

  • The underlying protocols for Quality-of-Service (QoS) over Wi-Fi were standardized several years ago, and enterprise wireless LANs now incorporate the relevant standards. However, adhering to the standards alone is not sufficient to build a superior multimedia-enabled wireless LAN. Rather, the network vendor needs to understand the fundamentals of how these protocols work, and then implement network configuration adjustments that dynamically and automatically tune the network to deliver end-to-end QoS.


HD-Quality Video Over WLAN Solution

  • The main technology enablers for video over Wi-Fi are adequate bandwidth, QoS and multicast support. While 802.11n provides a significant bandwidth boost, RF planning is still important to ensure continuous, high-rate coverage. RF management algorithms that include access point and client control, advance Wi-Fi system automatically calculate the optimum channel and transmit power assignments, move clients to the most appropriate access point and optimize the network’s use of available spectrum. Prioritization over-the-air uses the well-understood WMM protocol, which has been tested and interoperability-certified by the Wi-Fi Alliance.


HD-Quality IP Surveillance Over WLAN Solution

  • Video surveillance is being implemented on an unprecedented scale. Public safety agencies, municipalities, maritime ports, transit authorities and other government agencies depend on video surveillance to protect their constituents and property.

  • For law enforcement, video surveillance is essential to deter crime, improve incident response time and provide forensic data. Video surveillance is also essential for organizations that have infrastructures spread over large areas, such as public transportation, university and corporate campuses, retail, construction, logistics, mining, and oil and gas.

  • Today’s surveillance applications use digital cameras, monitors and recorders. Cameras can be remotely controlled, providing better and broader coverage. Ethernet and IP networks are the norm. Compression technology has advanced, as has image quality.


Wireless Intrusion Detection Solution

  • As wireless enterprise networks become more pervasive, increasingly sophisticated attacks are developed to exploit these networks. In response, many organizations consider the deployment of wireless intrusion protection and wireless intrusion detection systems (WIPS/WIDS). These systems can offer sophisticated monitoring and reporting capabilities to identify attacks against wireless infrastructure, while stopping multiple classes of attack before they are successful against a network.

  • Organizations have several options when selecting an architecture for WIDS deployment. These include an overlay approach, which uses dedicated sensors to create an overlay security network; integrated monitoring, which relies on dual-purpose transmission/sensor equipment that also carries customer traffic; and a hybrid approach, which uses elements of both of the other architectures. A closer look at deployment options shows that there are unique benefits and weaknesses associated with each. However, the hybrid model tends to offer the most flexibility and security because it provides focused analysis mechanisms, increased flexibility in deployment and powerful attack detection and response mechanisms. To maximize the benefits of a hybrid approach, however, vendor alternatives must be closely scrutinized to ensure that the vendor provides certain capabilities that are required to fully support a hybrid WIDS deployment. Such capabilities include an integrated identity-based ICSA-certified firewall and extensive wireless intrusion protection capabilities to ensure that the network can respond effectively in the event of an internal or external attack.


Secure Remote Networking Solution

  • Mobility in the corporate world is increasing at an incredible rate with users traveling around the globe and working partially or fully at home. The ability to move and remain fully connected is the paramount concern. The office connection must be pervasive, and it must be available no matter where the user is on the planet. Productivity can not be hindered simply because the user is not in the corporate office. The true key to mobility is making the remote system as easy to use as the corporate network, with the ability to support more than just the traditional data device remotely.


location-and-tracking

  • Enterprises lose millions of dollars a yea rbecause critical equipmentis misplaced, stolen or not maintained properly.As set tracking with Real Time Location Systems(RTLS) over Wi-Fi allows continuous tracking of valuable equipment or 
people over theWLAN. The ability to instantly locate a critical device can reduce not only replacement costs for lost equipment, but also enable far more efficient use of existing inventory. The result is reduced costs as well as improvements inworkflow, security and customer service.



Outdoor MESH Networking

  • Wireless mesh networks allows outdoor environments to be interconnected without any wires and with the security and reliability of a wired network. They solve a wide range of communications challenges across different outdoor environments, making them well suited for public safety, emergency response, oil rigs, video surveillance, large-scale events and transportation hubs.
