4ipnet presenta los puntos de acceso EAP760 y EAP767 AC1750 Dual Band para soluciones de WLAN de alto rendimiento

TAIPÉI, 30 de julio de 2014 /PRNewswire/ -- En el día de hoy 4ipnet, un proveedor líder en soluciones de LAN inalámbrica competitivas e integrales para satisfacer las demandas de Wi-Fi del mañana, anunció el lanzamiento de sus más recientes puntos de acceso interior 802.11ac: el EAP760 y el EAP767. Con velocidades de datos de hasta 1,3 Gbps en 5 GHz, funcionalidad avanzada de grado empresarial y un atractivo precio, los dos puntos de acceso ayudarán a que organizaciones y empresas satisfagan los requisitos de la mayoría de los escenarios de despliegue de siguiente generación. Cuando se los combina con el completo paquete de autenticación de usuario, aplicación de política y características de gestión centralizada de los controladores de WLAN de la serie WHG de 4ipnet, las necesidades de Wi-Fi de hoteles, universidades y empresas pueden ser fácilmente satisfechas.



La principal diferencia entre el EAP760 y el EAP767 es que el EAP760 se presenta con antenas externas, mientras que el EAP767 contiene antenas internas. Los usuarios pueden elegir un modelo, dependiendo de los requisitos estéticos o de cobertura de cada uno. Asimismo, el EAP760 presenta un exclusivo enlace descendente PoE (Power over Ethernet) que puede permitir al APs (punto de acceso) suministrar energía a otros dispositivos basados en IP (protocolos de Internet). Por ejemplo, los operadores de redes pueden desplegar fácilmente una cámara IP junto al EAP760, sin necesidad de cableado adicional.

En términos de similitudes, ambos modelos soportan la más reciente tecnología 802.11ac y presentan dos radios que pueden operar en las bandas de 2,4 y 5 GHz respectivamente. Tres secuencias espaciales posibilitan índices de hasta 450 Mbps en 2,4 GHz y 1,3 Gbps en 5 GHz, permitiendo que se concrete un verdadero rendimiento similar al del cable. El mayor rendimiento también ayuda a aliviar la congestión de la red, acortando el tiempo de uso promedio de cada cliente, lo que a su vez aumenta la capacidad de la red. Por último, ambos modelos soportan 802.3 en PoE, eliminando la necesidad de las tradicionales fuentes de energía durante el despliegue.

Aunque la tecnología 11ac refiere en gran parte al aumento en las velocidades de datos, los EAP760 y EAP767 incluyen mucho más que la mera velocidad de transmisión. A través de QoS inalámbrico, equidad en el tiempo de uso, tecnología de band steering y conversión multidifusión a unidifusión, los APs posibilitan la multiplicación de los beneficios que aporta la 11ac y mejoran aún más el rendimiento inalámbrico. Además, los APs pueden proporcionar seguridad de grado empresarial a través de características tales como la autenticación 802.1X, el cortafuego de capa 2 y el aislamiento de estación. Con el EAP760 y el EAP767, los operadores de red pueden ofrecer un excelente rendimiento y un ambiente inalámbrico seguro, reduciendo los reclamos de los clientes y eliminando los riesgos de seguridad. Por último, cuando se los despliega junto con los controladores WHG de 4ipnet, los administradores pueden configurar un equilibrio de cargas y un roaming (itinerancia) sin fisuras, a la vez que realizan una gestión centralizada de todos los APs. Considerando todos los aspectos, las empresas y las organizaciones encontrarán que la solución de 4ipnet satisface sus necesidades de LAN inalámbrica a un precio mucho más asequible, maximizando el retorno sobre la inversión.

In recent years, providing Wi-Fi has become a norm in the hospitality industry – a service expected not as a luxury, but as an amenity. However, faced with large numbers of concurrent users, increasing number of mobile devices per user, and increasingly bandwidth-hungry applications, many hotels quickly realized the need for user and network management. The Iberostar resorts in the Dominican Republic (Iberostar Bavaro Suite, Iberostar Dominicana, Iberostar Punta Cana, Iberostar Grand Hotel Bavaro, Iberostar Hacienda Dominicus, and Iberostar Costa Dorada) were confronted with the same issues, and set out to search for a feasible and cost-effective Wi-Fi solution. The fundamental requirements defined by Iberostar’s management team were detailed user authentication, role-based policy assignment, and quick account generation, all of which were aimed at addressing the deluge of smartphones, tablets, and other Wi-Fi enabled devices.

After evaluating 4ipnet’s proposed solution, Iberostar’s team found that it could fulfill all of their needs, and was very pleased with the results. They decided to deploy WHG711 Wireless LAN Controllers and HSG1250 Hotspot Gateways across the six Dominican Republic resorts, with each controller accompanied by a wireless ticket generator set that would help front desk staff quickly print account credentials for guests. At the touch of a button, tickets with login credentials and matching QR codes could be printed, allowing guests to connect to the network without the troublesome login process.

The primary issue that 4ipnet’s solution resolved was unauthorized Internet access, which was a major point of concern for Iberostar from the security and reliability standpoint. After the 4ipnet system went online, every user was required to authenticate before accessing the hotel network, regardless of being a guest or hotel staff. Users would then be applied different usage policies such as firewall rules or bandwidth limitations depending on their pre-assigned role. Finally, the hotel could limit the usage time for each guest account. The fine-grained user control and network management features helped Iberostar maintain a secure and high performance public Wi-Fi environment.

Other features found useful by Iberostar included the customizable captive portals and built-in billing plans. Customizable captive portals allowed each resort to tailor the user login pages with their own logo and visual identity. At the same time, the on-demand account billing plans allowed the hotel to monetize Wi-Fi, turning its wireless network into an additional revenue stream for increased ROI. In summary, 4ipnet’s WLAN solution not only greatly enhanced the hotel network’s security and performance, but also dramatically improved customer experience. Keeping guests happy and returning with quality Wi-Fi service was Iberostar’s primary objective, and 4ipnet’s solution helped accomplish that feat.

4ipnet Teams Up with NTT-AT to Deploy Enterprise-grade Wireless Infrastructure at Aoyama Gakuin University for Extended Wi-Fi Access

Through its partnership with NTT-AT, 4ipnet successfully delivered a comprehensive and competitive wireless LAN solution for higher education.

4ipnet, a leading provider of competitive and comprehensive wireless LAN solutions for meeting tomorrow’s Wi-Fi demands, today announced that it has delivered a revamped wireless infrastructure to Aoyama Gakuin University in Tokyo, Japan to address increasing BYOD needs. Designed and implemented by 4ipnet’s partner NTT Advanced Technology (NTT-AT), the solution aimed to enhance the mobility and e-learning experience at the university, and turned out to be a great success.

Proud of its 130-year history, Aoyama Gakuin University relocated its campuses in Aoyama and Sagamihara in 2013. The university consists of 9 undergraduate departments, 12 graduate schools, and more than 20,000 students in total. In recent years, the dramatic increase in usage of smartphones and tablets on campus have put an unpredicted amount of stress on the university’s existing WLAN infrastructure, resulting in poor Wi-Fi connectivity. Although the university realized that upgrading the WLAN infrastructure was necessary, providing a reliable Wi-Fi service for over 20,000 students was not an easy task. In addition to controlling the total cost of ownership, the deployment was expected to be time-consuming and difficult. Therefore, the university began its search for a solution that could provide reliable wireless access under a limited IT budget.

Mr. Mishima, an Assistant Professor from the Institute of Information and Media, recalls the situation: “In 2009, we deployed some APs, but only in certain public areas such as dining halls and common rooms. Since professors and students were increasingly using notebooks or tablets in lectures, they needed high performance Wi-Fi.” Acknowledging the need for an infrastructure upgrade, Mr. Sakata, a Research Associate and colleague of Mishima’s, consulted with NTT-AT on how to address these Wi-Fi needs, and was extremely surprised by the response he received.

“First, I asked about the deployment in classrooms. The number of APs and the plan given really amazed me! They were very precise about where the APs should be deployed through simulation of the building structures and calculating radio wave interference based on the floor plans. I never imagined that this was possible! We held an on-site investigation later on, but the results were almost the same as the original suggestions.” Sakata continued, “The proposed 4ipnet APs were very attractive in terms of cost performance. Therefore, we could increase the number of APs without exceeding the budget, and extend the Wi-Fi coverage beyond what we had originally imaged. Moreover, we realized that it is possible to deploy more APs when necessary, as the network is very scalable.”

“The pressure from students and faculty members has been substantially relieved. The achievement was not only due to the high performance of deployed APs, but also the optimized placement locations,” said Sakata with a smile. “They helped us think in the shoes of the actual Wi-Fi users, and provided us with accurate, concise, and flexible feedback. This is the most important reason why we can rely on them.”


Through its partnership with NTT-AT, 4ipnet has successfully delivered a fully-featured and .competitively-priced WLAN solution to Aoyama Gakuin University. After the deployment, the number of Wi-Fi related complaints has drastically decreased, reflecting both the reliability of 4ipnet’s solution and the high quality of initial deployment planning. With BYOD becoming ubiquitous and mobile usage rising rapidly, institutes of higher education will find that 4ipnet offers a flexible and effective managed wireless network, catering to all types of needs and situations.

4ipnet Wireless Access Point Optimization Part 8 of 8

Today we're putting an end to the wireless access point optimization series by introducing DHCP snooping and layer 2 firewall. Thanks for following through!

DHCP Snooping

In order for a device to begin using network services after connecting to an access point, it must first obtain an IP address from the network’s DHCP server. This is a point of vulnerability, as attackers can install their own DHCP server and assign clients arbitrary IP addresses and default gateways. In the worst case, a rogue DHCP server controlled by a hacker could potentially cause network administrators to lose control of their entire network, which is a major security flaw.

The DHCP SNOOPING feature on 4ipnet APs prevents this type of network failure by allowing network administrators to specify the IP and MAC addresses of trusted DHCP servers. As a result, the APs will filter out DHCP messages from unrecognized servers, preventing them from ever reaching client devices. Although DHCP attacks are typically not as big of a concern for small-sized networks, enterprise and government networks requiring the tightest of security measures will find DHCP snooping to be a beneficial added-layer of security.

Layer 2 Firewall

For security purposes, network administrators may sometimes want to block specific types of traffic directly at the access point, preventing them from ever reaching associated wireless devices, such as applications running on specific ports, or traffic originating from specific IP addresses. For example, if a school discovers that students are using the school’s network to play online games during class time, the school may want to block the port(s) that are used by the game to serve content. To address requirements such as these, 4ipnet access points are equipped with a LAYER 2 FIREWALL feature that help network administrators enforce usage policies.

Although firewall features are also available on 4ipnet wireless LAN controllers, there are a few major reasons for blocking packets directly at the network edge (at the access points):

Figure: Layer 2 Firewall can be configured to prevent unnecessary traffic from entering the wireless medium, improving overall performance


  1. Specific types of packets from the wired end of the access point will not be flooded out onto the wireless medium, decreasing interference and increasing overall wireless throughput.
  2. Malicious traffic from wireless clients can be blocked before ever entering the network, limiting the amount of potential damage.
Series Conclusion:

By introducing the various performance and security features on 4ipnet access points, the difference between consumer and enterprise-grade APs should now be much clearer – many of these features deal with applications and usage scenarios only found in large-scale deployments. In today’s smartphone and tablet environment, it is not uncommon to see an average of five to ten Wi-Fi enabled devices in traditional households. However, public Wi-Fi hotspots such as coffee shops, hotels, or office buildings may have ten times that amount or even more. The need for enterprise-grade APs is real. Enterprises and organizations have to address the ever increasing number of mobile devices and the seemingly insatiable desire for bandwidth. 4ipnet’s wireless LAN solution is well-aligned to help organizations of all types and scales face this rapidly evolving Wi-Fi landscape.
