Belden meets the Need for True Wireless Mobility

Today, we are totally dependent on “network access” to do business, gather information, monitor and analyze the activities around us, and communicate with other systems, networks, and people – all over the world. 

While conventional hard-wired networks meet these conventional needs, a new need is developing: the need for mobility. People are no longer willing to be tied to their desks; they can’t afford it.

Current wireless technology does provide a degree of mobility, but it suffers from a major limitation. These networks were designed solely to carry data. They were never intended to simultaneously handle data, multimedia streams, and voice traffic.

This means your mobile network users face various access problems that are a function of the wireless equipment they’re using, the type of information they’re accessing, and their physical location. This is hardly “mobility.”

In an ideal wireless networking world, none of these factors should arise. Everything should be seamless to the user – seamless mobility.

Only Belden’s Wireless Solution meets this ideal.

 

The Evolution of Wireless Local Area Networks

Classic wired LANs were created to provide fast data access from fixed locations. To turn these LANs into Wireless Local Area Network (WLANs), the standard approach has been to replace the fixed user locations – usually a wall- or floor-jack – with a wireless (radio) access point (AP). Each AP serves a physical area, or “cell.”

IEEE Standards 802.11a, 802.11b and 802.11g define wireless signals in terms of radio frequency, data rate, and other characteristics. These standards are the same as those used in a home network, often known as Wi-Fi®.

However, when this wireless technology is deployed in a cell-based fashion in large enterprise-wide or campus-wide environments, significant implementation, performance, and management challenges arise. In short, a large-scale, cell-based WLAN is achieved at the expense of performance and complexity.

Foremost among these challenges is the fact that cell-based systems are plagued by co-channel interference, which occurs when two AP cells operating on the same channel transmit at the same time. Such interference is the primary cause of diminished system capacity.

Next, even if you can live with co-channel interference, cell-based systems require personnel with deep RF engineering expertise. They need to perform RF site surveys to determine where to place APs, and they must also play a game of give-and-take to identify just the right balance of channelization, acceptable co-channel interference, transmit power, and unique antenna selection for each AP.

With the Belden® Wireless Solution, all of this RF-related complexity disappears. Enterprises cannot help but be surprised by the elegance and simplicity of this solution. There is no need for RF cell planning. In fact, only a rudimentary understanding of wireless is required.

 All-the while, network performance is dramatically improved with seamless mobility, ubiquitous coverage, elimination of co-channel interference, and unmatched system capacity.

 

An Elegant Solution to the Most Difficult WLAN Problems

The Belden Wireless Solution takes a fresh approach to high-performance wireless networking. It starts by eliminating the basic concepts normally considered the very foundation of wireless networks: RF cells and RF cell planning.

Instead, it uses a Channel Blanket topology in which each radio channel is used everywhere – on every access point – thereby creating blankets of coverage. A centralized Belden Wireless Switch combined with Belden Wireless Access Points form an elegant solution that avoids the classic problems of cell-based WLANs.

The result: seamless mobility with no security concerns, no roaming latency, no co-channel interference, robust client connections that simply do not drop, and the ability to design for a guaranteed and predictable level of service.

In addition, you can separate the Belden Channel Blankets to give your IT personnel the unique option of physically segregating different user types (802.11a, b and g), traffic types (voice, data, and video), and roles (private and public zones) onto different channels, thereby guaranteeing quality of service for all users. This is beyond, and in addition to, the traditional way of logically segregating users via VLANs.

 

The Mobility Benefits of Wireless

Easy to plan
No RF expertise is needed. Using Belden's software planning tool, you simply input the square meter coverage and the desired quality of service, and it will tell you how many AP's you need to use and where.

Easy to Deploy, Validate, and Maintain
Power over Ethernet is built into the Belden Switch, so there is no need for a Midspan an Endspan device.

Easy for Users
Users no longer need to consider their proximity to an AP to achieve connectivity. They go wherever they want, secure in the knowledge that their grade of service stays consistent.

Delivers the Highest Wireless Performance
Unlike the case of cell-based WLAN systems, Belden's unique architecture yields an enterprise grade wireless LAN and no tradeoffs between coverage, capacity and mobility.

Ubiquitous Coverage
The Belden Switch prevents co-channel interference by ensuring that only non interfering AP's are permitted to transmit simultaneously on the same channel.

Highest Capacity and Bandwidth
 - Eliminates "edge users"
 - Eliminates client "bunching"
 - Highest capacity through layered blankets
 - Boosts total system bandwidth

Seamless, Zero-Latency Mobility
In the Belden Wireless Solution, the user associates once with the switch, and then proceeds to move freely within the channel blanket, without ever experiencing inter - AP hand-off’s. This ensures that communications are never interrupted or disrupted by mobility.

Wire-Like Resilient Connectivity
The BWS is the only WLAN system that introduces the concept of uplink path diversity. Within the channel blanket multiple AP's can simultaneously hear the clients transmission. The switch selects the optimal point of reception for each packet instance.

A new level of Quality of Service (QoS)
The layered channel blanket architecture of the BWS gives IT unprecedented flexibility to dedicate physical channel bandwidth to one type of use over another.

This is the essence of true triple play convergence the data-voice-video Holy Grail of the WLAN world.
