If the average British family consumes 190Gb of data per month, imagine how that translates into business data consumption. Combined with the UKs trail blazing adoption of SaaS where 41% of businesses have adopted at least one cloud service. Without a solid WLAN infrastructure you risk a glitchy G Suite, sluggish Salesforce and unstable Amazon Web Service (AWS).

Picking the right PoE

For a service as mission critical as business Wi-Fi, selecting the right switches to power the network is crucial. For many practical reasons Power over Ethernet is the most popular choice for powering wireless access points.

There are six crucial elements to consider
before selecting a switch:

 

 
 
 
 
 
 
  1. PoE power budget and compatibility

    Each access point requires power. Firstly, check whether your access point needs a PoE or PoE+ connection. Then assess the power budget required by each wireless AP. The power budget for each device tells you the minimum power budget required from each port on your network switch. These two pieces of information will instantly narrow your choice of switch.

    When specifying switches, you need to understand the difference between PoE and PoE+ and how it affects your network.

    • PoE (802.3af) is the original standard which has a maximum of 15.4W per Ethernet port which equates to 12.95W that can be delivered up to 100 meters from the switch.

    • PoE+ (802.3at), almost doubles the available power budget, providing up to 30W per port, of which 25.5W can be delivered up to 100 meters from the switch.

    In other words, PoE+ has a higher power budget per port and will future proof your network with the latest backwards compatible power over Ethernet standards.

  2. Port speed

    Picking switches with Gigabit ports ensures high speed data transfer between the switch and the ceiling mounted access point so your team benefits from the fastest available wireless speeds.

  3. VLAN or Virtual LAN

    Many smart switches include the L2 functionality required to create VLANs. A virtual LAN has many practical and security benefits, it enables you to logically group users based on their role in the business. For example, create a separate network for the data hungry marketing department, therefore guaranteeing plenty of bandwidth for the sales team. Alternatively, add an extra layer of security by preventing people outside the Finance and HR teams from accessing sensitive data accounting and HR applications like Oracle, Sage and QuickBooks.

  4. Port security

    Wireless security is second nature. Security for fixed location devices like access points shouldn’t be overlooked when considering your networks overall integrity. MAC Binding is one of the most efficient ways to prevent rogue devices connecting to your network; it effectively locks a specific device to a single port on your switch. In other words, if someone unplugs an access point and tries to connect a laptop, the port will shut down because the MAC address has changed so you avoid unauthorised devices on the network.

  5. Port density

    As a rule of thumb picking switches with a higher port density provides better value for money by making better use of limited space and power. For example, three 8 port switches will support up to 21 individual devices. In this scenario, at least one port on each switch is used to connect to the network and you will need 3 power outlets, one for each switch. However, a single 24 port switch will power 23 devices and require just one power outlet.

  6. Configuration and management

    There are two options for setting up and managing switches, Command-Line Interface (CLI) or General User Interface (GUI). CLI is specific to each switch manufacturer, whereas GUI is a universal web interface enabling people with a networking background to install, configure and trouble shoot the switch without any additional training.
