Wireless ISPs

Before Bequant we were constantly getting complaints like “my Netflix is buffering” or “I am running slow” even though the customers were receiving their full allotted bandwidth. In the last two weeks since implementing the Bequant solution we have not received a single complaint! What a relief. It has been worth every penny. It is a great solution for the shortcomings inherent in the WISP industry.

We tested the Bequant TCP Acceleration (BTA) product for a couple of weeks and the results were impressive. So good in fact, we decided to purchase four devices and are considering buying two more. BTA has definitely provided an improved streaming service experience for our customers across the board, resulting in fewer truck rolls and higher customer satisfaction.


A WISP network can be very challenging for the TCP protocol, due to the latency variability and packet losses inherent to wireless communications. Servers using TCP (the majority) will therefore send data to WISP subscribers more slowly than what the WISP network can actually sustain. When the traffic flows through our BQN node, the Bequant TCP Acceleration (BTA) will not get confused by wireless access networks, and will increase the speed experienced by WISP subscribers, utilizing the unused capacity left by regular TCP. This will improve the quality of experience (QoE), the customer satisfaction and loyalty, and reduce customer support issues.

The DPI Analytics in the BQN node will also show which services are being used the most, and at what times. With that DPI information, the Bequant Bandwidth Management (BBM) functionality can identify and control the speed of some of those services, to avoid congestion situations and save in Internet connectivity costs.

Acceleration Results

This section shows the acceleration obtained with all the live traffic of a WISP network with licensed-band wireless links. The performance of each individual TCP transfer (downlink and uplink) is registered and the accelerated results are compared with the non-accelerated ones to obtain the acceleration percentage (the increase in average speed). Additionaly, you can also look at our Netflix results in different kinds of ISPs.

This chart shows average speeds over a week, with consistent acceleration effect in all network conditions. The image was generated in real time by the BQN online WEB interface, and provides 9 graphs for different categories depending on the download size and internet RTT.

Bandwidth Savings Results

The following graph shows the results of limiting streaming video speed to 2 Mbps per user in a cellular mobile network. The 2 Mbps limitation was enforced during even hours of the day, while no limitation was set on odd hours of the day, and the total volume of traffic sent every hour, for the whole network, was measured for four days. It can be seen that the overall volume of traffic was significantly lower (around 15% lower), and that the peaks in traffic were also lower when limiting to 2 Mbps. All these results were obtained with no customer complaints due to quality.

In a WISP, a higher speed limitations is required, from 3 to 6 Mbps, since subscribers can use high definition TV sets where lower resolutions are more noticeable. It may also make more sense to enforce this speed limitation only during peak hours, and to include software update services to the controlled applications during those times.


Bequant software runs on Bequant Nodes (BQN), which are transparently deployed as a bump-in-the-wire between the access gateway router and the Internet gateway router.

The BQN only needs to be on the path of the traffic to optimize and it is compatible with other network elements such as traffic/QoS policers or shapers. The BQN supports PPPoE, VLAN, QinQ and MPLS traffic seamlessly.
