Wireless Networks

High levels of cost reduction and increased efficiency can only be achieved with smart grids.

D-Link launches the DAP-2310 access point. Supporting the 802.11n standard, it offers Wireless N connectivity with 300 Mbps transfer speeds and advanced features accessible through very simple management, making it ideal for environments where it is desirable to simplify the configuration and maintenance of the wireless network environment.

AMS Technologies introduces the AireBeam 2012 series: the latest generation of backhaul solutions, featuring the G80-MX mid-range and G80-LX long-range bridges (70/80 GHz point-to-point backhaul solutions).
Whether connecting just two buildings or an entire city, LightPointe's new 70/80 GHz backhaul solutions are ideal for carrier-grade Gigabit Ethernet transmission.

Today's businesses rely on wireless networks and internet access to enable their employees to work as productively as possible. According to an IDC report, the Wireless LAN market grew by 20.7 percent in the first quarter of 2011, demonstrating the increasing importance of wireless networks across all sectors.

Libelium presents its new Vehicle Traffic Monitoring Platform, capable of measuring the flow of Bluetooth devices on a given street, highway, or passageway, differentiating between hands-free devices in vehicles and pedestrian phones. Sensor data is transmitted via a ZigBee multi-hop radio, through an internet-connected gateway, to a remote server. The traffic measurements can then be analyzed to accurately determine vehicle congestion or pedestrian traffic.

The ZOOM ADSL X7 n model 5790 is a modem/router/access point, Wi-Fi signal amplifier, which offers the following features:  

The dramatic increase in mobile devices with internet access, such as tablets and smartphones, has driven up the demand for Wi-Fi systems in urban areas. Public transportation is one of the environments where these systems can play a particularly important role. In Spain, they are already used by Madrid's Municipal Transport Company (EMT) buses, the 516 intercity bus line, and will soon be implemented on RENFE trains. The high number of people consuming bandwidth in these environments will require reliable and adaptive systems, and in this regard, Ruckus Wireless recommends intelligent Wi-Fi systems, such as access points with ChannelFly technology.

According to an announcement by Digi International, Siemens AG is using Digi X-Grid™ solutions to enhance its smart meter product with an internet-based energy management and consumption platform for consumers. The Digi X-Grid solution is an "extended grid" that enables real-time IP-based control and monitoring of household energy devices beyond just electricity meters.

Wireless LANs used to be more modest: they consisted of a group of easily identifiable devices and connected workstations, with simple infrastructure. Today, depending on the size of the company using it, a WLAN may have to operate with tablets, laptops, smartphones, and many other devices, some authorized and some not, and with the accidental security threats these could pose.

The way we use the internet has changed dramatically in recent years. Today, we expect reliable coverage in every corner of our homes. To make this a reality, D-Link has launched two new PowerLine solutions designed to offer users improved coverage, high-speed connectivity, and protection against dead spots: the Wireless N Gigabit PowerLine router (DHP-1565) and the PowerLine Passthrough family (DHP-P500AV and DHP-P501AV).

Moxa, distributed by Tempel, presents the new generation of access points, the AWK-6222, which can act as an Access Point, Bridge or Client in outdoor environments. 

The Xacon WiBe combines the features of a WiFi/3G access point and router to provide and improve available mobile coverage. It continuously analyzes radio base stations (BTS), selecting the one that offers the best transmission quality and highest speed at any given time.

It appears that by the end of this year there will be over one billion wireless devices worldwide*. Users of these devices are increasingly demanding the best possible connection to get the most out of their wireless network. To meet this demand, D-Link introduces the revolutionary SmartBeam™ technology.

This mobile router is an ideal solution for providing secure global communications to your remote systems, equipment, or networks. Using this mobile router, there are no distance limitations for remote site monitoring.

Microchip expands its MiWi™ Development Environment (DE), which provides a complete ecosystem for designing wireless star and mesh products.

TP-LINK, a manufacturer of networking products for consumers and businesses, presents the TL-WA901ND wireless access point, which achieves a data transfer rate of 300 Mbps, making your Internet connection run smoothly, without interruptions and at maximum speed.

In order to increase productivity, companies are looking for ways to reliably and securely connect their various branches and remote workers to their corporate networks, while adjusting their investment to increasingly tight IT budgets.

The Xacom AT-2200 is a 3G signal repeater that provides improved mobile coverage for UMTS networks. It is designed to help resolve coverage issues and enable data transmission in a variety of indoor spaces, such as offices or homes, up to 150 m²².

There are numerous aspects that a clock tree must consider regarding the radio cards of fourth-generation WiMAX or LTE (Long-Term Evolution) wireless base stations. In addition to the restrictions imposed by the OFDM (Orthogonal Frequency-Division Multiplexing) protocols themselves, analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), as well as RF mixers, present serious overlap and filtering problems. This article focuses on the challenges related to modulation elements.

Ciena, the networking specialist, offers telecom operators technology capable of supporting mobile data traffic for the 270 million cars in Europe that will be interconnected in the near future. Carrier Ethernet solutions prevent the saturation and bottlenecks that such demand will generate with currently available networks.
