Voice and gaming suck on Clear - Sprint 4G? HAHAHA

2009-10-31 20:41:57

I've been using Skype the past week and there's no way Clear could be thinking of using this network for voice. The latency is so bad, there's huge delays in conversation and drop outs. Like everyone else with WiMAX, the ping to the first hop is 50ms and higher, and the very best rating I get from pingtest.net is borderline B rating, VoIP can suffer and videogames. So I've been videogaming, playing Quake Live and the only servers I can compete on with Clear are the Seattle servers that I get 70ms pings to. SF, LA, Chicago, Dallas, all these other servers my 100ms+ ping makes me easy picking for the other players. I could go back to Comcast and get 20ms pings to these same servers, but I'm stuck in a location currently where I can't get a wired connection. One thing that stumps me is why the Clearwire customers, who use similar and less sophisticated technology than WiMAX, are able to get 2-3ms pings to the first hop and pings on average, 40ms lower than Clear. Information from wimax.com suggestions there's a huge latency performance problem with Clear WiMAX. quote:Quality of Service (QoS) is what determines if a wireless technology can successfully deliver high value services such as voice and video. The chief detractors from good QoS are latency, jitter and packet loss. Solve these issue and you have a carrier-grade service. Very simply put, WiMAX offers a very low latency across the wireless span. Most ven-dors have products where latency is less than 10 milliseconds from base station to CPE (and vice versa). To put this in perspective, latency must be measured end-to-end. VoIP, for example, is highly susceptible to latency. If latency exceeds 150 milliseconds for ex-ample, the quality of the conversation begins to drag. At or above 200 milliseconds many listeners may find a conversation unintelligible. In the case of WiMAX, the large majority of latency will not occur on the air link be-tween subscriber and base station but rather on the wired portion of the connection be-tween the subscriber and what ever the "other end" might be (web site server, IPTV server or VoIP called party). The figure below illustrates how any latency on the wireless portion of a network is minimal relative to that on the wired portion of a network.

Clearwire To Recieve New Funding

2009-11-09 10:50:04

Clearwire Corp. will be receiving at least $1.5 billion of new funding from its partners. It is said Sprint will provide $1 billion and its Clearwire joint venture partners, a group which includes Comcast Corp., Intel Corp, Time Warner Cable Inc. and Bright House Networks LLC, would kick in another $500 million. This should help with the rollout of the network in many new cities. http://online.wsj.com/article/SB10001424052748704402404574524152073150702.html?mod=googlenews_wsj

Access to Clear Modem?

2009-11-06 12:42:02

Is there a way to change settings for the Clear modem. Like for example according to people Ive spoke with both the router and the modem have DHCP turned on which could affect signal and quality of speed. So I was wondering if there's a homepage for the modem with all the settings there that I can access. Like how for linksys routers it's 192.168.1.1 I just got it 2 days ago in Raleigh, NC. So far it's OKAY. The webpages are loading kinda slow though when compared to TWC. However I think it's cuz we're in the middle of the transition. Also I was using it on my mom's laptop wirelessly connected to the Linksys router. I have the Clear Voice as well which so far seems to be exactly the same as TWC phone service. But my main issue is to get to the Motorola modems home page so I can look at the settings. IS that possible or not?

I'm going to check out the service after work today. Anyone have it yet? Does anyone LIKE it? From what I have been seeing, people are having horrible latency problems.

[General] Signal Strength/Range: Clear vs Clearwire

2009-07-08 13:20:11

I originally posted this as a review... but it might have been better to post it here. Sorry for the repeat posting. I have been using clearwire for almost exactly one year and have been very happy with the service. I live about five miles from the nearest tower (located in Sedro Woolley, WA) and with the modem on my roof I can reliably get between 1 and 3 bars of signal strength. The DL speeds will vary from 300-2000 kbps while the UL speed is almost always 256 kbps. I have the 1.5 mbit service so I am pretty happy with the results especially since I have no other options for high speed access. The connection is negatively impacted by heavy rain and snow... but for the most part, like 95% of the time, I have a good connection. So... along comes the wimax upgrade offer from clear. More speed at the same price seems like a good deal to me. So get the new modem, install it in the same position as the existing modem and get zero signal. I wander all over my roof with the modem looking for any sign of a signal and get nothing. Bummer. Does anyone know how the source signal strength of the wimax compares to that of their existing service? I spent about 30 minutes on the phone with clear customer service last night. While they were polite and easy to understand they seemed to be quite inexperienced in dealing with connection issues. We kept on going back to changing the location of the modem... to which I responded I have already tried that. The call ended with the tech telling me there wasn't anything he could do for me. What have other people's experiences been like with this upgrade process? Soo... I'm still running clearwire with a pretty solid connection although lately the quality seems to be dropping. Perhaps this is their way to force people into making the upgrade. [Update] I just got done looking at the clear website and according to their coverage maps they don't even have clear service in my area. Which makes me wonder... why did they offer to send me an upgrade? [Update 2] I just talked to the guy at the local clearwire shop and he said that the service was turned on but not officially announced. He also said that the clear wimax had less range than the normal clearwire service... 6.9 miles vs 10 miles. I assume that these ranges are over estimates but that the roughly 30% reduction in range is accurate. From the sounds of it he had been many calls about this issue.

clear shareholders meeting tomorrow

2009-11-09 14:42:57

Clear is holding their third quarter earnings conference call tomorrow afternoon. http://investors.clearwire.com/phoenix.zhtml?c=198722&p=irol-newsArticle&ID=1341957&highlight= I plan on listening in to see what they have to say about their progress with the new wimax system. Their second quarter financial report has some interesting stuff in it about how they were expecting an increase in "churn" with their pre-wimax customers. "Churn" is the rate of subscribers dropping their subscriptions. For the second quarter I think the churn rate was 2.8%. It will be interesting to see what the churn rate is now that the pre-wimax system has been turned off and all those customers outside of the wimax range have to terminate their service.

Clear vs. Energy Efficient Windows (Motorola Modem)

2009-11-02 21:49:24

I signed up for Clear today (Dallas/Ft. Worth) and bought the Motorola standalone modem (box says motorla WiMAX CLEAR Modem, Wave 2, CPEi 25150). I took it home and hooked it all up and started doing speed tests. With the modem perched on my window sill, I got 1 bar, occassionally 2 bars. With the window open and the modem untouched, I got 5 bars. Here are the speedtests: Closed window Opened window I was on the phone with tech support for over an hour trying all sorts of different things, but the clear verdict was that my windows were causing massive signal disruption. The windows are very energy efficient. My electric bills are usually under $30/month for my 750 sq. ft. apartment and considering I have tons of electronics, I can thank those windows for some good savings...but when it comes to WiMax, they are a killer. Clear is planning to send a tech out here to help troubleshoot and come up with a solution. Otherwise, I'll have to cancel and go back to using Time Warner :\ Does anyone else have experience with this Motorola modem and energy efficient windows?

Service was out about 10 hours in my location. First time it has been that long.

Max speedtest on test tower - Las Vegas

2009-11-08 06:38:37

This was preformed on a new tower array we were testing. Although a customer would not be provisioned for this service level. I though some of you fans may appreciate seeing this.

VoIP on other service?

2009-09-30 05:06:19

Can one have clear phone as a standalone? Tempting..
