AMR-NB G.729 CDMA iLBC DSP + Howler Tech. Nice.

Thursday, February 12th, 2009

Don’t bother reading on if the headline means nothing to you. It’s geekery time. It is most definitely time for the ’science bit’.

Yes.

Howler Tech is live.

Dan Lane and Ed Hodges — regular contributors here at Mobile Industry Review — have come out of the shadows.

If you’ve ever spoken to them or their colleague Jay Fenton (also a contributor now and again), you’ll have had to smile politely when they tell you they’re in ’stealth’ mode.

They’ve spent many a networking evening dying to tell everyone about what they’ve been up to. But the actual stuff they’ve been working on is not that far off rocket science. Indeed, if you’ve ever watched any of the Terminator: Sarah Connor Chronicles episodes, Dan, Ed and Jay should be looking over their shoulders for any 6ft blonde Terminator T-888s out to neutralise them. I’ve not seen Caraya, their product/service in the flesh. But I’ve seen the bits and pieces that make it up. And it does look a bit SkyNet to me.

The sort of thing that a lot of telecoms industry giants should have seen coming and snapped up last year.

I expect there’s still potential to buy the company for a decent sum now, but I reckon the valuation will sky rocket shortly. Enough to justify the simmering telecoms warchests, I’m sure.

Wossit do? Well I can tell you, because it’s sort-of public.

It converts voice.

Quite a simple ask, you might think. But no. The fact that I can’t walk down sodding Tottenham Court Road without losing a signal or talk to you on my Blackberry Bold, or hold a decent audio conference with chaps abroad — that shows that voice isn’t fixed yet. It’s not fixed because we’re now using a plethora — a veritable PLETHORA — of communications codecs to transmit voice.

Try this on for size: You’re in the States on a CDMA Sprint mobile handset right? Our colleague is on a landline in Canada. We all dial into a conference bridge. I call from my 3Skypephone using SkypeOut.

How many codecs d’ya reckon are in use?

Yeah. No wonder the quality’s shit. My voice has to be transcoded in real time (or, more likely after 2-3 seconds of annoying delay) from one format to another format and another.

Echo.

Did… did… did you… can you … can you hear me? Hello?

Rubbish!

Enter Caraya. Software based packet processing. Instead of vomiting out maybe a few hundred channels (MAXMIUM) like the usual kit out there, Caraya — combined with a few smart Terminator SkyNet style chips — knocks out thousands upon thousands of channels simultaneously.

Nice.

So that cash you’re blowing on codec conversion systems? Give Howler a call. If you’d like an intro let me know or simply hit’em up at http://www.howlertech.com/.

PS: When Howler is sold for $100m, remember you heard that prediction here first.

And, er, I’ll carry your briefcase, Ed.

Nokia goes after US with “lots of devices”

Tuesday, May 6th, 2008

The US has always been a bit of a thorn in the side of the US – it’s never managed to get a real foothold over there and it’s been losing market share hand over fist. But not one to give up, it’s revealed that it’s planning to get more handsets into the US, according to Reuters, which quotes Nokia chief designer Alastair Curtis as saying: “In the next few months [US] operators will carry a lot of new products from us” and it will be producing a raft of new products specifically for American consumers, with most of its efforts going into CDMA devices.

It’s probably a good time for Nokia to go after the US: Motorola’s still struggling to come up with successor to the Razr and Samsung could be on the back foot after losing its CEO recently. That said, Nokia’s previously efforts into CDMA haven’t really done it justice: it called off a CDMA device partnership with Sanyo last year and at the time indicated it would be leaving CDMA alone for the foreseeable. It looks like Nokia is serious about having another crack at the US: can’t wait to see what it comes up with.

Deutsche Telekom to buy Sprint?

Monday, May 5th, 2008

According to German paper Der Spiegel, Deutsche Telekom is considering going shopping and acquiring US carrier Sprint Nextel, with a view to merging it with its own T-Mobile USA.

It’s a fascinating rumour but I’m not entirely convinced that this isn’t just an idle ‘what if?’ scenario from some Deutsche Telekom exec. Granted, for anyone considering an acquisition of Sprint, it’s a great time – the company’s been struggling of late, its share price is down and it could be snapped up for a bit of a bargain price. It would mean a big step up for T-Mobile in the US, catapulting it into the top tier of operators.

But the major reason to say no to such a deal? The tech. T-Mobile uses GSM, while Sprint Nextel uses CDMA and is trying to get a WiMax network up and running at the same time. The integration problems don’t put any acquisition in a favourable light.

Telstra bids adieu to its CDMA network

Tuesday, April 15th, 2008

Telstra has finally received the go ahead from the Aussie government to close down its CDMA network, after three months of waiting. The telco had hoped to close it down in January of this year, after its 3G network reached the same coverage levels, but was prevented by the government.

The country’s communications minister said at the time that Telstra had problems with handheld coverage, how customers were informed about the changeover and issues with how its 3G handsets were being sold. Telstra has now satisfied the government that it’s fixed up all the issues and can shut off CDMA.

While the network was still popular with some users, notably farmers, the vast majority of users had already migrated to Telstra’s 3G network, known as Next G, so it was only a matter of time til it bit the dust. That said, the postponement of the network earlier this year threw a sour note into the relationship between the new Rudd government and Telstra – hopefully the closure will go some way to restoring their mutual appreciation.

Sprint: looking at Deutsche buy, Nextel spin off?

Monday, March 10th, 2008

Rumour mills are great fun. And there’s been some great rumours coming out of the US mobile industry in the last couple of days, both concerning Sprint Nextel and what might be its next move in the face of some ongoing financial troubles.

The first rumour comes from suggestions by analysts that T-Mobile parent Deutsche Telekom might be interesting in buying Sprint to stave off pressuring resulting from the US price cutting frenzy. It doesn’t sound an altogether likely scenario to me. There’s the question of all the incompatible technologies – T-Mobile’s GSM, and Sprint’s CDMA and WiMax. Granted, T-Mobile would get some more customers, but Sprint it losing those at a rate of knots and would land itself in a technological and regulatory minefield.

The other rumour, courtesy of Seeking Alpha is that Sprint has hired Morgan Stanley with a view to spinning off Nextel, with an announcement due shortly. While this would seem equally daft at first glance – Sprint would lose all the investment it put into Nextel not long after acquiring it – there could be some sense here. After the massive writedown Nextel generated in the last set of Sprint’s results, why not admit it didn’t work out, give up trying to merge the two companies and their networks and just focus on CDMA and WiMax?
