WiFi eats wired for breakfast...

For most small to medium sized businesses, a wireless network has become the order of the day. Running cables throughout the office is not only time consuming but also expensive. A wireless network is cost effective and also a lot less cumbersome to set up. For a small business, a wireless network offers many benefits, the most prominent being:

  • Easy to setup and access
  • Scaling is easier and faster
  • Flexibility for employees

Ok, so let’s say that you do understand the usefulness of a reliable wireless network and are sold on upgrading to a wireless network. However if you do not have the experience, building one can be a little tricky. It is definitely not as simple as plugging in your router and connecting your device. Here are a few tips that will surely help you build the right network for your business needs.  

 

1) Plan your network for growth

One of the common mistakes that businesses make is not understanding the importance of access points. It is quite common that the network load is not considered when determining the number of access points required. You may think in terms of the number of users but users rarely operate a single device. Each user usually has multiple devices such as a laptop, smart phones, and a tablet. Additionally,  other office devices must be considered such as printers, video conferencing equipment, and security cameras. It is therefore important to err on the side of caution by installing multiple access points. This helps not only in preventing network congestion but also prepares you for additional network load coming from new hires in times of growth. Our rule of thumb is one enterprise-grade wireless access point every 1000 square feet. And don’t forget to professionally mount them on the ceiling in optimized locations. 

 

2) Backup dual internet access

Without high speed internet, your whole office probably comes to a stand still. You need internet for communicating with your customers, using web tools, research, reading this blog and much more. Unfortunately, ISPs do go down from time to time. And when it’s your ISP that goes down, you need the peace of mind that comes with having a secondary backup ISP! We are so much dependent on the internet that businesses cannot function with service disruptions. However, we can safeguard against this by signing up with two different internet providers. This way you have a fall back option when one of the ISPs goes down.

Using dual internet access does not have to be a costly affair. You can have a more dependable ISP as your primary and keep a lower-tier plan from another provider as a backup. If the idea of managing two separate ISPs seems intimidating, it is advisable to seek professional help. 

 

3) Choose the right hardware

The most important factor contributing to a reliable wireless network is hardware. It is important to understand that there is a limited spectrum available that is shared among various devices and is influenced by external interference, such as your neighbors’ wireless network. Choosing the right hardware therefore should be on top of your list because it can help mitigate the negative influence of external factors outside of your control.

Wave 2 802.11ac have become the norm when it comes to access points. Getting anything other than 802.11ac would not make any sense today. The access points come with 1x1, 2x2, 3x3, 4x4 radio/antenna chain. The 1x1 supports one receive stream and one transmit stream, while the 2x2, 3x3. and 4x4 support 2, 3 and 4 streams respectively. Therefore investing in a 4x4 is a worthwhile investment and will support your future expansions. In most of our corporate installations, we tend to prefer Cisco Meraki or Aruba wifi gear. 

 

4) Choose the right cable

A solid underlying wired network goes a long way in ensuring a fast wireless network. Your cables are responsible for delivering sufficient bandwidth to your access points without which your WiFi network will become sluggish. Therefore, using the recent cable standards such as CAT6 for your LAN wiring would be a good investment. This also allows you to connect certain devices such as printers, IP cameras, etc to the wired network thereby freeing the spectrum from wireless dependent devices such as laptops, and mobiles devices. Also plan on running two cables to each wireless access point because current and future standards will need the extra wired bandwidth. 

 

5) Setup guest WiFi

If you have customers, or other visitors that frequent your office, they would most likely want to use your WiFi to connect to the internet. If your network does not have a separate network for guests, it can pose a serious threat to your network security. Business grade access points on the other hand support multiple wireless networks also called SSID (service set identifier). This gives you significant flexibility as well as security. You can now give guests internet access without giving them access to your internal network. These SSIDs can also be assigned different policy, encryption, authentication, etc. in order to ensure added level of security.

 

6) Choose the right channel

When you are setting up your wireless network you probably are in a great rush to finish things off. You may therefore be tempted to use the default channel on your router. This may work well if you are doing this for your home. However, if your office is located in a commercial or business area then you will be fighting with your neighbors for the same airspace, meaning frequent interference that hampers your wireless network. You can easily mitigate this by changing the channel when setting up your device. Business grade access points also come with the capability to monitor neighboring wireless networks and dynamically manage channels. Having such a capability can be a great asset if you are working in high density WiFi areas.We find that if you’re constantly having to tinker with your channels manually, then you should probably upgrade to a more enterprise-grade option that can handle this for you automatically. 

 

7) Don’t ignore the dual band

Your router probably offers simultaneous dual band. This means you have 2.4 Ghz and 5 GHz bands available for use. It is advisable to use the 2.4 GHz band for IoT devices while reserving the 5 GHz band for laptops. This can help keep the 5 GHz band less congested. Further, as the 5 GHz band has shorter range, it allows you to use additional access points without the risk of interference in high density airspace. Most enterprise wifi equipment will simultaneously use the 2.4 GHz and 5 GHz bands and will automatically steer your devices to the best option available.

Building a robust and future ready wireless network is quite a challenge but it is certainly worth taking on. If you plan the entire project, use the right hardware and configurations, it will ensure that you have a fast, versatile, and capable network equipped for the unexpected. This is a crucial business requirement and if you have even a sliver of apprehension about your ability to set up and roll out a wireless network at your workplace, it is advisable to get professional help.
