![]() I am sure he did this because he realized that I knew a little something about what was going on as it has never happened before. When we couldn't resolve the problem he said he would (Shocker!) schedule a service call to my home. The servie rep said that they too use a 'version" of ookla so if i wanted to use the app I had installed it would be fine. but as we chatted I mentioned that I was using ookla speedtest to verify connectivity speeds. With them on the phone we went through the usual reboot modem, etc etc. I though it was my provider and contacted them. Once I had the website I could use it with only a slight degradation in speed (per ookla). All worked great at first but after a couple days the wifi speed degraded and it began to take forever to find a website, (over 2 minutes). I use Spectrum for my internet access at home, (don't have many options).Īnyway, the new Linksys unit became my primary with two of the old units set up elswhere in the house to act as children/secondary units. However, upload speeds and latency were disappointing showing the carrier still has some fine tuning to do.I recently upgraded my home wifi with a new Linksys MX4200. The test’s blazing download speeds showed strong support for the carrier’s HSPA+ capabilities and handily outpaced the rival 3G networks. The test showed average download speeds of 2.8 Mbps, average upload speeds of 278 kbps and latency of 480 ms. A bit of a letdown, but still very close to what Sprint Nextel’s 3G network provided Editor score: 7/10 The final test was on AT&T Mobility’s HSPA+ network using the Samsung Captivate and running the same speed test application. The results seemed to contradict the carrier’s network coverage maps claiming HSPA+ capabilities where I conducted the tests, instead showing speeds more in line with traditional HSPA capabilities. The device, using the same speed test application, provided an average download speed of 864 kbps, average upload speed of 595 kbps and latency of 150 ms. Editor score: 8/10 Next up was a similar Samsung Vibrant running on T-Mobile USA Inc.’s HSPA+ network. So while speeds were down considerably compared with the devices WiMAX capabilities, coverage was far superior to its faster cousin. The network download speeds were at the low end of the 600 kbps to 1.4 Mbps advertised by the carrier, though upload speeds were at the higher end. ![]() An average of three successive tests using the same Epic 4G device, but with the WiMAX radio turned off, produced average download speeds of 845 kilobits per second, average upload speeds of 635 kbps and latency of just over 200 ms. First up was Sprint Nextel’s CDMA2000 1x EV-DO Revision A-based network. Editor score: 9/10 Following my return from the trip, I decided to see how those numbers compared with the 3G offerings by some operators. While not the true 4G capabilities expected to of a network labeled at “4G,” the service matched its advertised speed claims, though continued lack of coverage is still a concern. The speeds posted by the service were roughly in line with the 6 Mbps downlink and 1 Mbps uplink speeds advertised by both Clearwire and Sprint Nextel. Latency typically ranged between a low of 100 ms up to around 200 ms. ![]() Further localized testing showed occasional download speeds of nearly 9 Mbps with upload speeds topping at just over 1.1 Mbps. During my “official” test of speed measurements the phone managed to post average download speeds of 5.3 megabits per second, upload speeds of just over 1 Mbps and latency of around 120 milliseconds. To this device I downloaded a “Speed Test” application that provided data for downlink, uplink and latency. Epic 4G device that was running Google Inc.’s Android operating system. ![]() To test network speeds I enlisted the help of a Samsung Electronics Co. Coverage at ground level out and about in Chicago also proved strong, though the 46th floor room I was staying at in the city did see signal strength dip, though I was able to remain connected to the network. Coverage moving closer to the interior of the enormous building slipped a bit, but was still sufficient. Coverage at the McCormack Convention Center was not surprisingly strong, especially nearer the outside windows and close to meeting rooms set up by both Clearwire and Sprint Nextel. network was fairly robust on the different environments encountered. Coverage from the Clearwire Corp./Sprint Nextel Corp. Last week’s 4G World event in Chicago gave me the opportunity to try a commercially launched WiMAX network for the first time and for the most part I came away impressed. ![]()
