> Convenience : Access your network resources from any location
> Mobility : You're no longer tied to your desk, as you were with a wired connection
> Productivity : Helps your staff get the job done and encourages collaboration
> Easy setup : You don't have to string cables, so installation can be quick and cost-effective
> Expandable : You can easily expand wireless networks with existing equipment
> Security : Advances in wireless networks provide robust security protections
> Cost : Because wireless networks eliminate or reduce wiring costs, they can cost less to operate than wired networks
To future-proof your network, you need to incorporate wireless technology into your structured cabling system. Plan on complete wireless coverage, which, oddly enough, means more cabling not less. It also means going through the alphabet soup of wireless networking and infrastructure standards.
> Site Survey
The stratospheric growth in the use of mobile devices has meant that the provision of wireless communication within the majority of buildings has become not only expected, but in many instances mandatory. Both mobile and public safety operators face the challenge of delivering comprehensive coverage within a building in an affordable manner. The ability to achieve good quality coverage from external base stations is increasingly difficult. Our comprehensive range of in-building coverage systems, provides solutions for small to medium and large buildings ensuring high quality wireless coverage is achieved throughout. The systems are designed by certified network design professionals.
> Campus & Stadia
Delivering high capacity wireless coverage across campus or stadia infrastructure or small dense urban areas has become a key requirement for wireless operators across the world. The advent of smartphones which are heavily in use in these environments puts increased pressure on the capacity load of the network, particularly due to the scale and nature of such complexes. The ability to provide full and comprehensive coverage when and where it is needed is key. Our high capacity DAS and coverage products provide an infrastructure capable of supporting multi sector and multi band systems for both public safety and cellular operators thus ensuring users of both services can make full use of their communications networks.
> Coverage Extension
Extending the reach of wireless communications into rural or remote areas is a growing problem for all types of network operators. The very nature of the environment means that services such as power are difficult to deliver and very often it is both impractical and uneconomical to deliver coverage using a traditional base station approach. We use frequency shifting and band shifting repeaters to deliver an easily deployable, low cost and low maintenance coverage system which is equally applicable for both public safety and cellular wireless.
> WLAN Roaming
WLANs are relatively inexpensive to deploy compared to wired networks, and because throughput is directly related to the proximity of WAPs, network managers often install WAPs to provide overlapping signals. Using this overlapping design, coverage (radius) area is traded for improved throughput. Note that these overlapping signals must be in non-overlapping channels. This scenario, however, requires WLAN roaming. WLAN roaming plans consider that as a user moves away from a WAP and is therefore losing signal strength, his connection should seamlessly jump to a WAP that provides a stronger signal.
> Point-to-Point Bridging
It is not always feasible to run a network cable between two buildings to join their respective LANs into a single Layer 3 broadcast domain. If the two buildings are a reasonable distance apart and preferably in direct line of sight with each other, wireless bridges can be configured. It takes two WAPs to create one logical two-port bridge. In this mode, WAPs are operating in a dedicated point-to-point bridge mode and therefore are no longer operating as wireless access points for clients.
Site surveys, originally introduced to make the most of scarce resources, are sometimes seen as unnecessary in this age of inexpensive WAPs, where wireless saturation seems so economical. Maybe the days of serious physical surveying, where one would look under the ceiling tiles, are long gone, but you should still perform surveying to determine the optimal locations for WAPs to minimize channel interference while maximizing the range. Whether you are performing an in-depth site survey or a rudimentary one, you should ask the following questions :
- Which wireless system is best suited for the application ?
- Does a line-of-sight requirement exist between antennas ?
- Where should the WAP be located so that it is as close as possible to clients ?
- What potential sources of interference are in this building ?
- Should any federal, provincial, or local regulations and legislation be considered in this deployment ?
Some WAPs have an auto configuration option with which, after listening on the network, they can auto configure themselves for the least-used wireless channel. This is not always desirable, though. For example, if a WAP is installed on the sixth floor of a multi-WAP, multistory building, it might select a channel that it perceived to be available. If that channel is already used by a WAP on the first floor, a client on the third floor could have difficulty staying connected because the channels overlap there. Overlapping channels in a wireless network perform similarly to an overcrowded wired network plagued by continuous collisions. Undoubtedly, performance will suffer and clients might not be able to establish consistent connectivity to the wireless network. This problem could be more easily solved with rudimentary planning and by using nonoverlapping channels.
A wireless local-area network (LAN) uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you're connecting to that business's wireless network. A wired network connects devices to the Internet or other network using cables. The most common wired networks use cables connected to Ethernet ports on the network router on one end and to a computer or other device on the cable's opposite end. In the past, some believed wired networks were faster and more secure than wireless networks. But continual enhancements to wireless networking standards and technologies have eroded those speed and security differences.
