The Importance of Wireless Access Points for Your Business

Let’s first look at what a wireless AP is, and why it’s important. A professional-grade AP (for example a Ruckus R770) is a device in a wireless local area network (WLAN) that acts as a communication hub for wireless device users to connect to a wired network.

In the context of commercial wireless installations, APs are strategically positioned throughout a business environment to expand the coverage area of the wireless network and support the number of concurrent users typical for that environment.

Here’s a breakdown of the key functions and considerations for APs in a commercial setting:

Functionality

Connectivity: APs provide a wireless connection point for devices like laptops, smartphones, and tablets to connect to the organization’s network and, by extension, to the internet.

Network Extension: In large or densely structured commercial spaces where a single router’s wireless signal may not suffice, multiple APs ensure comprehensive coverage across the entire area.

Traffic Management: APs can manage network traffic, directing data packets to the correct devices and helping to maintain network efficiency and speed.

Key Features for Commercial Use

Dual-Band Operation: Many commercial-grade APs operate on both the 2.4 GHz and 5 GHz wireless frequencies, allowing for more devices to connect without interference.

Scalability: Commercial environments often require the network to scale with the business. APs can be added as needed to accommodate growth.

High Capacity: Designed to support a large number of simultaneous connections without degradation in performance, crucial in high-density settings like offices or public spaces.

Security: Commercial APs come equipped with advanced security features to protect the network and data, including WPA/WPA2 encryption, VLAN support, and guest network capabilities.

PoE (Power over Ethernet): Many APs support PoE, allowing them to receive both power and data connection over a single Ethernet cable, simplifying installation and reducing wiring needs.

Planning for Wireless Access Point Installation

If you are researching implementing a revised wireless connectivity strategy for your space, it pays to plan how the installation should be done. That means assessing your business wireless needs and taking stock of all the devices that will be using the network at any given time.

Take the time to consider:

  • What are the traffic demands?
  • What coverage areas need to be included?
  • What are the implications for device compatibility across your network?
  • Are there indoor as well as outdoor spaces that require coverage?
  • What sightlines are available, and are there any considerations where sightlines are obstructed?

You will be better off if you can answer these questions and keep a current record of everything you can provide to a cabling company. The more information a structured cabling company has about your space, the better they can perform, and avoid unforeseen challenges. For example, if multiple buildings in a location are expected to share a network, how far are they apart, and what is between those buildings that may cause logistical barriers to clear connectivity?

The Role of A Wireless Site Survey
