Clearwire Starting TD-LTE Network Build
Build Begins This Quarter, Launch Still in June of 2013
Clearwire says the company will begin building their TD-LTE network during this quarter, with plans to significantly ramp up the build by the fourth quarter of this year. Speaking at an investment conference this week
, Clearwire re-iterated that their goal is to have 5,000 LTE cell sites up and running by June of 2013. The company had previously suggested they would start the build in the first quarter of this year, claiming
that their LTE network will be capable of top theoretical speeds of 168 Mbps downstream. Clearwire will of course be needing money and some new investors; Google offloaded their investment in the company in the first quarter, and Time Warner Cable sold their 7.8% stake this week

Re: Bullplop! Uh...you're the one who's full of BS. The LTE on ym iPad (VZW) will beat 99% of WiFi hotspots to pieces, as long as I'm in an LTE coverage area (any big city in the Lower 48, plus lots of medium-sized ones) Coverage is reasonable, too.
We aren't talking about Clear WiMAX here, which admittedly has coverage issues, particularly if you're using a mobile device to access their network.
Speaking of Clear, the point of their TD-LTE system will be to deliver breakneck speeds to a small area, offloading users who would normally be clogging up the macro-cellular network at large events, schools, airports and the like. So that way, when you walk into /name of team/ stadium, your service will get better instead of failing altogether.
said by banananaz :It's crappy but at the same time very good spectrum. It's geared towards very dense deployments. Imagine if they are able to come to an agreement with the cable MSOs and deploy on cable lines (sort of like WiFi ap's are today).
The problem is clears crappy 2.6ghz spectrum which can't penetrate buildings for crap. If lte will be in the same range its going to be just as crappy.
You might even look at some situations of where they could deploy on street poles etc. There is a lot of potential if clearwire can keep it's Wimax spectrum holdings (the broad spotty coverage).
Then they could really build out a dense LTE-TD network in a few cities and really own those cities. Almost all the congestion is in urban areas and they plan to make a significant chunk of their cash selling excess capacity to other carriers.
I'm curious if they plan to offer a retail solution to customers directly or keep the LTE-TD network strictly wholesale.
Re: Bullplop! Clear could do that without the MSOs. They just need to go to the cities and power companies and get access to the street lights. They could create a HUGE Network without any issues. An AP every X amount of poles, and all backhauled to the tower. They'd give any DSL and MSO a run for their money. Especially since it'd be totally wireless. They could do mobile that way and fixed.
meh I posted this on another site, but will repost it here. Again, why is everyone so fixated on LTE????? The biggest problem right now that carriers should be concerned about is back haul bandwidth, not wireless coding methods. According to one article written in 2009, at that time, over 90% of Clearwire and Sprint WiMAX towers were connected via microwave back haul. Another site claimed each microwave link had a total capacity of 80mbps. Think about that for a second. In several other countries, individual houses are getting 1gbps+ fiber connections, but here, the entire cell site to be shared amongst hundreds or even thousands is wired at 80mbps??? WiMAX 1 has theoretical max download speeds of 37mbps per user. In my testing across the U.S., even when within 100 feet of a Clearwire/Sprint tower, speeds average around 10mbps. What is switching to LTE towers going to do? I could hook up a fancy new Wireless AC router to my 6mbps DSL line, but what is going to change??? Clearwire should have gone all out with the WiMAX network and gotten speeds as fast as possible on that network before even considering a switch to LTE. Now they have two 4G networks that are only meh at best, as both still dont have the bandwidth to really be 4G networks, and soon will have a fragmented device lineup between WiMax and LTE devices.

Re: meh Yeah, backhaul isn't their problem. You can always increase the number of microwave links. Spectrum and tower placement is their problem. Clear was stingy with WiMax spectrum, and even more stingy with base station placement. Wimax has no peak theoretical per user - peaks are for an entire cell. There is no guarantee per user, as that's dependent on cell load, distance, obstacles, etc.
Moreover, there can be any number of cells on a tower depending on how they want to configure it based on usage in the area. It's quite a bit more complicated than simply whatever the backhaul to the base station is.
Hell, you can have 10GigE to a base station, but if you've only got 10mhz of spectrum allocated (even though Clear has about 150mhz available to them) then you're only gonna get ~40mbps per cell.
Your end-user testing is fatally flawed from the get-go. First of all, Clear throttles connections. They definitely throttle on the upload (i can't recall if it's 1mbps or 1.5mbps, I believe just 1), and the download may or may not be capped as well. Since you aren't a network engineer for Clear, you can't know what network management they've got going on that's affecting speeds. In other words, end-user results are never a good judgement of technology being used, other than to establish minimums. That is, if you're getting 22mbps on an HSPA+ network, you can be sure that you're on 42mbps HSPA+ at least for T-Mobile. However, if you're getting 4mbps you could be on 7.2mbps HSDPA, 21mbps HSPA+ *or* 42mbps HSPA+, since you have no clue about what your cell's overall load is, and thus why exactly you're getting the speeds you're getting.
Switching to LTE is simply moving over to a single wireless standard. Being on a standard means a higher likelihood of device support (at lower prices) in the future, as well as more potential customers (not direct consumers, mind you, but roaming/capacity partners like ATT/Sprint/TMO and Euro roamers).
