Since March 2004, our focus as an innovative router supplier has been on mobile broadband. Here are all the ground-breaking technologies of the day we have pioneered across the years.

  • • 2004: UMTS-TDD
  • • 2005: FLASH-OFDM
  • • 2006: iBurst
  • • 2007: 3G/HSDPA (3.6Mbps)
  • • 2008: 3G/HSUPA (7.2Mbps)
  • • 2009: 3G/HSPA+ (21Mbps)
  • • 2010: 3G/DC-HSPA+ (42Mbps)
  • • 2011: 4G/LTE (Long Term Evolution)


We identified several unique advantages with 4G/LTE:

Ambitious coverage plans

As operators deploy 4G/LTE, they are working on widening out their footprint of radio coverage. Many of them are attaining more attractive radio frequencies that will help boost coverage throughout the rural areas. The lower the frequency band, the wider the coverage; even if at risk of lower speed to the end user. The goal is to maximize coverage as capacity is something that'll be increased as part of the ongoing 4G/LTE development. With the acquisition of such radio bands (and refarming existing bands), a high speed mobile broadband network will be as widely available as 2G/GSM has been to date.


Low Round-Trip Latency - Perfect weather for your online gaming and conferencing!

A low round-trip latency is a key weather condition for online gaming and audio/video conferencing. Some of us online gamers here at Dovado identify this to be the most critical component as it reflects on the entire realtime user experience of the Internet. Unlike previous mobile broadband technologies (up until the introduction of 3G/HSPA), the latency between the computer and the mobile network was considered too high to for a realtime audio/video conference; forcing people to take long frustrating pauses between responses.

With the introduction of 4G/LTE, the average latency between your home and the 4G/LTE mobile network (and back to your home) is approximately 20 milliseconds (currently, reaching a low of 11ms!) as opposed to 50-300ms on previous networks. This is very much in par with Cable Internet, ADSL and in some cases; Fiber To The Home! The 4G/LTE infrastructure suppliers have mentioned numerously that the average latency time will drop as the 4G/LTE networks evolve during the coming few years. Online gamers know how critical this feature is as it will make a big difference when it comes to winning or losing their online game!


Uplink Speed - A really sweet bonus!

In many cases with 4G/LTE, the uplink speed tends to be faster than most downlink speeds on other forms of fixed/mobile broadband! This will allow you to upload that photo album or video to social networking sites and friends in no time. A higher uplink speed will also ensure that the other end of your video conference will get to see a far clearer picture of you with a far smoother flow of frame rates than ever before. Though most 4G/LTE operators do not advertize this capability, we see it as a major bonus and quite a game changer for the Internet experience as it widens out the potential for new applications that were previously underserved in terms of bandwidth. Uplink speeds are usually between 10-50Mbps.


Downlink Speed - Your ultimate reason to go for 4G!

Please read our observances & recommendations surrounding radio interference.

This applies to 4G frequencies close to WLAN at 2.4GHz, ranging from 2300-2600MHz

According to the website of the Swedish Post and Telecom Agency (PTS), the 4G/LTE networks operate on the 2500-2690MHz bands in Sweden. This is also the case in many other parts of the world as well (Europe, Middle East, Africa and parts of Asia in particular). As these frequencies are on the close border with those of WLAN (a radio interface which is available in most routers, operating within the 2400-2484MHz range), there has been observed interference between the two.


Here is what we have observed and verified in a 3rd party radio frequency test lab:

  • • Using the modem directly within the router will provide good speeds if your WLAN-connected computer is situated very close to the router.
  • • Widening out the gap between the computer and router will result in a speed drop (on the Internet connection) for that particular computer.
  • • The reason for this is because WLAN outputs more power with distance in order to compensate any loss. In doing so, the interference becomes more apparent as Internet speed drops. This is normal behaviour for WLAN and mobile devices in general. The further the distance, the more power.


A simple solution to this phenomenon:

  • • Create a gap of at least 50cm between the 4G/LTE USB modem and the router with the help of a USB cable. Most USB modems tend to include a USB extension cable, so please check the modem packaging box.
  • • Maximum cable length tested is 5 meters, however we have not done any long uptime tests with such lengths and therefore cannot guarantee performance based on that.
