Want Better Wi-Fi Performance? Try These 4 WAN Optimization Tips

By: Danny Mareco July 21, 2015   0 Category: Strategy, Design, Managed WiFi, Performance

In nearly every industry today mobile devices are being used more than ever before. From schools to healthcare institutions and corporate offices, individuals depend and rely on the uninterrupted use of their smartphones, tablets and wearable technologies. 

For instance, BYOD relies exclusively on users’ utilization of their own mobile devices for work or learning purposes. Healthcare providers are using smartphones and tablets more often these days to provide a higher level of patient care, and students are using mobile workstations during class for an interactive learning experience. 

With more traffic and demand being driven across your network, this new wireless landscape is starting to create some serious Wi-Fi performance issues particularly when it comes to bandwidth.  


In order for these mobile devices to perform as they should, administrators and decision-makers must ensure that their wireless networks have the capacity to support them.

One of the most effective ways to support this dramatic growth in Wi-Fi dependency is through WAN optimization. At it's core it will help you prioritize your traffic and guarantee that your mission critical applications are fully supported. 

WAN optimization can offer your network the boost it needs to increase your wireless network's performance. To help you have better wifi performance, try our 4 WAN optimization tips:

1. Traffic Shaping

In order to make sure that your bandwidth is being used for the right applications at the right times, organizations can implement policies for traffic shaping to limit or restrict usage so that traffic caused by non-work related usage like Netflix and Facebook doesn’t hinder your Wi-Fi performance. 

Organizations can gain increased visibility to identify and control traffic for better bandwidth utilization, so that resources are allocated for mission critical applications.

This will give priority to applications that are actually essential to the business or institution instead of wasting vital bandwidth on those that don’t.

2. Caching

Caching makes better use of the bandwidth you already have, thus providing the illusion of a faster WAN. 

The basic process of caching servers is to store the most recent and most frequently requested data so when that same data is requested later it doesn't have to be pulled from across the WAN or internet again.

For example, the next time a user searches for the same file or data, instead of starting a new search again for that same data a locally stored copied is pulled up which saves a ton of time and resources by not having to load the page as if it was new from across the web.

3. Data Deduplication

To try and put it simply, data deduplication is a process for getting rid of duplicate data. In other words, extra copies of the same data or file are deleted, resulting with in having one stored copy.

To make sure that each single piece of data is in fact the only single instance of that file, the stored information is analyzed replacing and found duplicates with reference points that points to the original stored data.

This reduces the data that must be sent across the network by sending references instead of the original data; on the plus side by reducing the amount of data that must be stored on the network you also save a lot of money too.

4. Data Compression

Data compression contracts the size of the data to limit bandwidth usage. Data is compressed on the WAN link and then automatically decompressed once the data is delivered, which in turn makes the Wi-Fi network more efficient by saving valuable space on the link.

To get a better idea of what this means think of military personnel using abbreviations for commonly used words. Yes they could say each place or action but it's much faster to just say the abbreviations. Using shortcuts to represent common data sets is the core of most compression procedures.


Today's wireless environments are getting more crowded everyday with more traffic being driven over the network than ever before causing serious bandwidth and performance issues.

You have two choices buy more bandwidth or as we've suggested here, maximize your current infrastructure through WAN optimization.
