From the monthly archives: "October 2012"

 For those of you that haven’t seen the movie “Groundhog Day“, it’s a 1993 vintage movie starring Bill Murray and Andie MacDowell in which the main character, Bill Murray playing a weatherman named Phil Connors, is stuck in a time loop, reliving the same day over and over again. So I feel like it’s Groundhog Day. Again.

Mea Culpa, I started thinking this way about the football team I coach. We just relive it over and over each practice and each game, and I’m like Phil Connors, trying everything to break out of the loop but I digress here. This context is about the state of the LTE marketplace. 

So the US LTE market is searching around for equilibrium and has temporarily stabilized on operators offering LTE as a premium service with ATT and Verizon coming in at nearly the same costs per Megabyte at various usage points, the large OEMs offering nearly the same eNB/EPC packages everywhere (with the same old incentives etc…) in the same old business models, hearing about the upcoming small cell revolution ad infinitum, the daily PRs about an iPhone/iPad killer, the yearly iPhone/iOS release hype, Samsung and Apple lawsuits over LTE, on and on. Maybe I’m just being cranky but there seems to be a whole lot of ho hum same as it ever was marketing and product and service designs just being recycled. 

Networks aren’t being run autonomously by SON (yet)…heck most large US operators haven’t invested in Remote Electrical Tilt (RET) for their sites yet. There’s no LTE roaming yet. 

Even 

the most interesting developments are ghosts like SuperWifi (whitespace radio), Lightsquared’s GPS fizzle, news like Clear just turned down their heat considerably with their TDD LTE plans, and band 12 deployments are nowhere, VoLTE is LaTE. 

I mean, even TDD-LTE and 802.11ac are becoming increasingly blurry to the point it’s hard to tell which is which. The future of Release 10 and VoLTE etc aren’t here yet so I can’t consider these things.

There are a couple of outliers, like the crazy things that Lemko claims and so on but I’m talking about real change.

The future seems promising and a break from the blase but how long are we going to be stuck in this loop? Where is the REAL innovation? Where’s all the startups with the innovative SDR, noise canceling thing we can’t even imagine but will change things forever? I’m ready for more intelligence, faster gratification, less suffering all that good stuff technology promises. 

I can’t stand to read any more PRs about a LTE enabled Band 17 or Band 13 device that is better than an iPhone/iPad that I can have for $200 on a year contract extension.

OK, just feeling a little sorry for myself may this will pass so I’m going to curl up with my Gartner Hype Cycle, maybe watch a little Star Trek and dream… 

 Having spent more than a decade working at an Asian conglomerate, I can appreciate the occasional feelings of corporate loneliness and therefore the need to put out some PRs to get some of the love back. So in this week’s episode, Huawei’s propensity to enable corporate or state espionage in communication networks is being debated publicly (it is an election year in the US) and their response is SingleSON. This SON server can surveil and monitor ALL of your networks, including InterRAT and heterogeneous networks. OK, it sounds a little fishy but let me explain.

So Huawei is advocating a single SON control point for multiple deployed networks. This is really a reasonable approach that allows such things as InterRAT network improvement, traffic steering and ultimately less OPEX via manual intervention.  There’s nothing earth shattering here  so I probably don’t need to go into great detail. They have plenty of good materials handy.

There is this groovy video that explains…

From their site” Automatic control of multi-mode and multi-layer networking has become key to enhanced O&M efficiency. Through self-configuration, self-optimization, and self-maintenance, SingleSON smoothly adapts to single-mode, multi-mode or multi-layer networking, which benefits not only efficiency but also OPEX.”

SingleSON white paper here.

So the timing is a little off but the functionality is good if you are worried about integrating LTE and legacy networks. The SingleSON control point manages via Operational Support System (OSS) interfaces to InterRAT, legacy and Heterogeneous networks and integrates them with a single game plan. From my point of view, I would be tilting towards sunsetting the existing legacy networks and may hesitate to invest in them but each company has it’s bits to bear. Good stuff…

Been following this but wasn’t sure it was on anyone’s else’s RADAR. Today, it popped up in Technology Review so I thought it was good to mention they have an article about it.

What is it? It’s is Network Coding for TCP.

What does it do? It overcomes the congestion and lossy packet problems that cause network throughput drops. Whenever a TCP packet comes out of order or doesn’t arrive, there are a lot of NAKs/ACKs etc.. that have to happen to restart the flow and there is a lot of latency to make that happen. Using some simple algebra that helps recover from errors (not error correction in the typical sense) and new rules, the flow of packets can be greatly accelerated under lossy conditions such as everyday in wireless networks. Papers explaining simulation runs are showing typically between 20% and 40% improvement under lossy conditions. (40% over 0Mbps make it feel huge.)

A startup by Caltech and MIT named CodeOn has been set up to license this groovy game changing technology.

Hope to see this used ubiquitously on the mobile internet! (within the LTE infrastructure and UE)

 Been super busy working on multiple projects, trialing new equipment, writing code, patents ugh. Have been working on getting some information on LTE that’s not protected by an NDA out. Hopefully Today! Happy Friday!

So I’m trolling the internet during a conference call and whoa, what’s this? An article in CNET about LTE speeds. Seems like everyone is interested in LTE all of a sudden. Anyway here’s the page:

 Don’t get me wrong, I laugh at Verizon and AT&T’s LTE implementations but this article makes me want to cry. The REAL reason the speeds in NYC are averaging in the 20MBps range and Sydney is like 40MBps is…

 

Verizon and ATT have 1/2 the bandwidth deployed that Optus (Australia) does! (FCC Hear that?) The US operators’ Verizon (Band 13) and ATT (Band 17) have deployed 10MHz channels in lower 700MHz with 2×2 MIMO whereas Optus (Band 3) has a 20MHz channel with 2×2 MIMO. Double the resource, double the rate.

 

VoLTE

VoLTE

Voice over LTE (VoLTE) is the next big thing. In fact, in 24 months, virtually all LTE enabled smart phones will support it. Curious?
Small Cells

Small Cells

Small Cells, previously known as 'femto' or 'pico' cells are possibly a savior to network operators. They offer capacity and coverage to the end user and are inexpensive for the network operator. Why aren't they everywhere?
