Ericsson Stalls on 3G Femtos

Despite the hype surrounding femtocells, Ericsson AB (Nasdaq: ERIC), the world's dominant WCDMA vendor, says the 3G home base station market is not mature enough for it to introduce a 3G femtocell.

Ericsson has already developed a GSM femtocell as part of a home gateway that includes a WiFi access point, a home router, and a DSL modem. The vendor says this product is ready for deployment, although no operator has launched the service yet.

But as for the 3G flavor of femtos, Ericsson is prepared to follow the market, rather than lead.

"We plan to release a 3G femto when we believe the market is ready, which for the moment is believed to happen in 2009," says Ulf Ewaldsson, vice president and head of Product Area Radio at Ericsson.

Analysts say Ericsson's decision is due to the fact that the high-volume, low-cost nature of the small home base stations threatens the vendor's core macro cellular infrastructure business.

"Femtocells serve to further commoditize the cellular base station market," says Heavy Reading senior analyst Patrick Donegan. "Hence Ericsson welcomes the femtocell about as much as IBM welcomed the PC."

Ericsson is presumably not keen on spurring the commoditization of its business, especially considering the financially disastrous second half of the year it is having. The vendor issued a shocking profit warning in the third quarter, which resulted in the swift departure of its CFO, and it has also predicted a weak fourth quarter, with margin pressure weighing on the infrastructure business. (See Profit Warning Slams Ericsson , Ericsson Warns on Q3, Ericsson CFO Steps Down, , Ericsson Predicts Weak Q4, and Ericsson Hangover.)

In the Unstrung Insider report, "3G Home Base Stations: Femto Cells & FMC for the Masses," chief analyst Gabriel Brown wrote: "One reason why Ericsson, like other large vendors, may have been cautious about this market is that even optimistic sales projections would barely make a meaningful contribution to the firm's revenues."

Brown adds that Ericsson's 3G product timeline might sincerely reflect its research and development plans as well as concerns about certain unresolved technical issues.

"It's likely Ericsson doesn’t see the market developing until 2009 and the schedule simply reflects prudent R&D investment," says Brown. "The vendor has also long argued that the potential problems of femtocell interference with the macro network have been underestimated by competitors."

Ericsson isn't the only vendor going cautiously here. Nokia Networks is staying clear of producing its own femtocells.

NSN's home access offering is a network gateway with open interfaces so that femtocells or other customer premises equipment can be certified to interface with it. Airvana Inc. is NSN's first femtopartner. (See Femto Players Gun for Gateways, NSN Intros 3G Femtocell, NSN, Airvana Team, and Thomson, NSN Team.)

re: Ericsson Stalls on 3G Femtos Interference control between macro and femto layers is tricky but apparently some vendors know how it do it. Seems like Ericcson might be simply running late on this one...

re: Ericsson Stalls on 3G Femtos It may well be true that Ericsson is careful on 3G femto cells because of its stake in 3G macro cells, but I do agree with them on the interference issue. Even though its "easier" to do network planning with CDMA or WCDMA (than with TDMA, or even OFDMA), it is not trivial. Self-installable base stations are unlikely to make it easier. Although this is unlikely to be a show-stopper, it's the kind of thing people tend to gloss over when talking about the wonders of femto cells.

The main issue remains: How much does a femto base station need to cost to make it an attractive business model?

This is one of the key issues, but it is one that people have put a lot of work into.

Not just vendors (ipAccess, Ubiquisys etc) but the carriers too have done a lot of modelling.

Quite alot of this has been presented in 3GPP and 3GPP2 and is accessible through their websites.

The Femto Forum is working on an 'open' model people can see and examine, but it isn't done yet.


Qualitatively, two arguments make sense:
- One of the biggest problems with cdma systems is 'near-far. To the extent femtocells remove a lot of terminals from being 'far' (loud, lots of interference) and make them 'very, very near' and hence quiet that helps the whole network.

- The inbuilding attenuation that makes coverage bad alsop acts well as isolation.

Now, I fully agree that hand-waving isn't modelling and what will matter are the corner cases, but the analysis so far does look promising.

Of course, to make this work does require some sophisticated smarts and RRC in the femtocell - that is the secret sauce of the maufacturers.
