Revenue from sales of IEEE 802.11 wireless Lans dipped to $352m (£241.8m) in the first quarter, from $363m in the fourth quarter of 2001, according to Seamus Crehan, an analyst at Dell'Oro. Over the same period, Ethernet switch sales declined about 2%, he said.
Both markets were probably hit by a typical first-quarter decline in enterprise investment in network equipment, according to Crehan. Wireless Lan revenue was up sharply from a year earlier, when it came in at $235m.
Meanwhile, first-quarter Ethernet switch sales, reflecting the generally weak economy, were down substantially when compared with the first quarter 2001 total of $3.1bn.
The wireless Lan market should show strong growth for the year as a whole, as it did in the consumer segment in the first quarter, said Crehan.
"It is still very healthy. I think what we've seen is a dichotomy in the market where consumer was still very strong but enterprise was down," he added.
Another possible factor in the enterprise decline was sales leader Cisco Systems' introduction of a new line of wireless Lan products in April, which some companies may have been waiting for.
Wireless Lans that use the IEEE 802.11a standard, a faster alternative to the widely used 802.11b technology that came on the market late last year, accounted for just $9.5m of the total revenue in the first quarter.
Dell'Oro expects to see that segment grow in 2002, but in the overall market 802.11a still will have a relatively small impact this year, said Crehan.
"802.11b still has an awful lot of legs, and the prices are still coming down," he said. "I don't think there's going to be a mass migration [from 802.11b to 802.11a]."
Cisco led in wireless Lan market share with 15.7%, followed by low-price equipment makers Linksys Group with 14.3% and Buffalo Technology with 12.7%.
The Ethernet switch market dipped 2% from the fourth quarter to this year's first quarter, with overall revenue remaining at about $2.7bn, according to Crehan. Cisco, the revenue leader in this market as well, gained share to 67% from 63% in the previous quarter.
Cisco performed well in one fast-growing product category: fixed-configuration switches with Layer 3 routing capabilities, according to Crehan. As prices decline, demand for Layer 3 functionality is expanding from the large chassis-based switches typically found in the core of a large network to smaller switches in departments and medium-sized companies.
