Wlan & Structured Cabling

Technology Overview

Keep Users Connected with Wireless LANs, Organizations worldwide are deploying wireless networks to increase productivity, enhance collaboration, and improve processes.

Instant interaction, text paging, voice services, and network access while traveling are transforming the business environment.

IEEE Standards for Wireless

  1. 802.11a – for 54 Mbps 5 GHz Band (Operational Frequency)
  2. 802.11b – for 11 Mbps 2.4 GHz (Operational Frequency)
  3. 802.11g – for 54 Mbps 2.4 GHz (Operational Frequency)

The following components work together to create a unified wireless network:

  1. Client Devices: These connect desktop and mobile devices to the wireless LAN in 802.11a-, 802.11b-, or 802.11g-compliant networks. Most of today’s laptops are wireless-enabled, and many specialized wireless client devices are now available.
  2. Access Points:These help connect wireless devices to networks, providing ubiquitous network access for many wireless environments.
  3. Network Unification:This is critical for network control, scalability, security, and reliability. Integration into existing networks enables system wide functions including security policies, intrusion prevention, and RF management.
  4. Network Management: As wireless networks grow in scale and complexity, management becomes more critical, requiring central design, control, and monitoring.
  5. Mobility Services: A comprehensive wireless network provides built-in support for leading-edge applications such as wireless voice over IP, location services, advanced security, and other emerging technologies.

Structured Cabling System(SCS)

Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems.

Structured cabling falls into six subsystems:

Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications, using category 5 (CAT 5E) category 6 cable (CAT 6), category 6A (CAT 6A) & category 7 (CAT 7) and modular sockets. These standards define how to lay the cabling in a star formation, such that all outlets terminate at a central patch panel (which is normally 19 inch rack-mounted), from where it can be determined exactly how these connections will be used. Each outlet can be ‘patched’ into a data network switch (normally also rack mounted alongside), or patched into a ‘telecoms patch panel’ which forms a bridge into a private branch exchange (PBX) telephone system, thus making the connection a voice port. Lines patched as data ports into a network switch require simple straight-through patch cables at the other end to connect a computer. Voice patches to PBXs in most countries require an adapter at the remote end to translate the configuration on 8P8C modular connectors into the local standard telephone wall socket. No adapter is needed in the U.S. as the 6P6C plug used with RJ11 telephone connections is physically compatible with the larger 8P8C (RJ-45) socket and the wiring of the 8P8C is compatible with RJ11. In the UK, an adapter must be present at the remote end as the 6-pin BT socket is physically incompatible with 8P8C.

It is common to color code patch panel cables to identify the type of connection, though structured cabling standards do not require it, except in the demarcation wall field.

Cabling standards demand that all eight connectors in Cat5/5e/6 cable are connected, resisting the temptation to ‘double-up’ or use one cable for both voice and data.

On this given technology road map, we, at Wizertech, understand all possible edges for an end to end physical connectivity( structured cabling) and have a wide range of product line & service line. Wizertech has certified engineers on Structured Cabling System (SCS) who are technically qualified to supervise & install any sized Building wide or Campus Wide cabling architecture.
