PCCW Drops Navini

PCCW Ltd. (NYSE: PCW; Hong Kong: 0008) has dropped broadband wireless access vendor Navini Networks Inc. as a supplier of its U.K. network rollout.

In May this year PCCW’s local subsidiary, U.K. Broadband, announced plans to launch a 3.4GHz wireless broadband service in the Thames Valley area, using kit from both IPWireless Inc. and Navini. The network can potentially cover approximately 300,000 homes in west London (see PCCW Fixes UK Wireless and IPWireless Powers PCCW).

The company is now attempting to extend the service throughout the U.K., ploughing a reported $40 million into the commercial rollout of up to 60 base stations next year.

“We will be engaging in a phased rollout approach in urban areas starting in 2005,” marketing manager Hannah Williams tells Unstrung. “We have now been given funding for next year because our soft launch in the Thames Valley was successful. We are taking a prudent and balanced approach to that program.”

Despite the earlier partnership, Navini will not be included in such plans. “We were using both IPWireless and Navini Networks in the trial, but will be working with IPWireless as we progressively rollout. The technology [from IPWireless] was more in fitting with what we wanted to do,” says Williams.

IPWireless is attempting to court carriers with its high-speed time-division duplex (TDD) data system, which conforms to universal mobile telecommunications system (UMTS) standards but -- unlike standard cellular systems -- uses unpaired spectrum, sending and receiving data on one channel rather than two (see IPWireless Flies the TDD Flag and IPWireless Fattens Its Wallet for more detail on the vendor’s offering).

In contrast, Navini Networks is one of a glut of startups now talking up the nascent 802.16 market (see WiMax Gets 'Smart').

Navini is still listed as a partner in a statement on U.K. Broadband’s Website. The same blurb also notes the service provider will in the future “support the emerging WiMax standard for portable wireless broadband.”

Such a move now seems a distant venture. “The IPWireless technology we are using is based on UMTS-TDD and has the same future technology roadmap as 3G,” adds Williams. “It possesses the same qualities as the WiMax standard, ie portable, non-line-of-sight, broadband access. The difference is it is available and up and running today, whereas WiMax seems to be some time away. That is the reason for our decision.”

Navini could not be reached for comment by press time.

re: PCCW Drops Navini
Since PCCW is one of the investors of IPWIRELESS so they have no choice but to promote IPWIRELESS technology.

Navini walked into a trap setup by PCCW and IPWIRELESS.

As if anyone cares.
Since PCCW is not buying anything anytime soon anyway. Navini knows the game very well having run a gazillion trials all over the world.
They are lucky not to be sucked down with this one further and saving the little funds they have.

re: PCCW Drops Navini
Found this in a report on FCC filings. Presumably they are talking about the 2.5 GHz spectrum that Nextel-Sprint own. If you link this with Nortels CEOs key-note at CTIA, things seem to being forward fast now for IPWireless...

Nextel Bullish on TD-CDMA

In separate studies, Nextel said it evaluated TD-CDMA technology, which it said is capable of operating on 5MHz, 10MHz, or 20MHz carriers in a TDD mode. An FDD mode has recently been developed, too.

"TD-CDMA FDD could support much higher bandwidth to the end user devices or increase system capacity significantly -- attributes that a carrier could combine to offer never-before-seen levels of service," said Nextel.

Nextel should think about it carefuly.
TD-CDMA is no good, dont work with voice and uplink data is no good.
Softbank in Japan test ipwireless TD-CDMA equipment but it does not work good. Softbank will use WCDMA.

re: PCCW Drops Navini
What Softbank said about uplink data rate and voice performance of IPWIRELESS TD-CDMA equipement is correct.
Checked with the guys at Woosh and they said the same thing, they can only get uplink data rate of 50 kbps if they are lucky. They could only get 10kbps when they use 5mhz carrier.
For voice they can only get few users per sector and IPWIRELESS told them that they could get more than 20 users....this is shocking....
IPWIRELESS is known for lying they said.
Woosh will go bankrupt soon with this kind of service.
Does anyone know what happened to that operator in Malaysia who selected IPWIRELESS few years back? Have not heard from it lately.

re: PCCW Drops Navini
What did Softbank say? Missed that one, is there a link?

Have not heard specific numbers as you quote on IPW/Whoosh, but have heard generally the same comments (poor uplink datarates, very low voice capacity), as well as high latency, low & highly flucuating uplink datarates. And not just at Whoosh also see Airdata (Germany), Sentech (S. Africa). Malaysia was to be AtlasOne in conjunction with Thales (France) as partner. Not sure what happened to that one but do not think it went ahead for whatever reason. Navini is there, as is Soma.

Would also note at the same time these comments/complaints would appear to be the same for other vendors as well, again not hearing such specific numbers though.

re: PCCW Drops Navini
Who cares what Softbank said, the bottom line is they kicked IPWIRELESS out and going for WCDMA.
The same for T-Mobile, they tested out IPWIRELESS gears and at the end they selected Flarion.

Check out the below link for complaints from Sentech customers on IPWIRELESS technology.

Simply put TD-CDMA doesnt work !!!!
This is the reason why none of the telecom vendors is developing the technology.

re: PCCW Drops Navini
TD-CDMA is works in small office or in small area like WI-FI.
It does not work in outdoor because interferene from many sites and because of interference between uplink timeslots and downlink timeslots.
People in Japan like FLARION, IBURST and NAVINI better for wireless braodband. IPWIRELESS people lies too much.

re: PCCW Drops Navini
Dear Mr. Toshi,
I assume that you have hands on experience with IP Wireless TD-CDMA equipment.
Please share with me the experience that you have with latency, spectrum efficiency, uplink throughput and downlink data throughput.
Currently we are evaluating IP Wireless and other wireless broadband technologies and just want to make sure that we select the right one.

UTSTARCOM who is IP WIRELESS reseller has presented to us some performance index but we find it's difficult to believe them. Especially when we hear many complaints about IP Wireless products.


Thank you in advance.
