Worldwide shipments of cable modem units are picking up, with growth of seven per cent between the first and second quarters of this year.
Revenues also rose, by six per cent to $235.8m (£149.3m), according to a report from Infonetics Research.
The group's Cable Aggregation Hardware and Cable CPE quarterly worldwide market share and forecast also reported that global cable modem termination system (CMTS) revenues reached $120.5m in the second quarter of 2003, a 41 per cent increase from the previous quarter.
"The cable modem termination system (CMTS) market is finally picking up again after a three-year downturn," said Michael Howard, principal analyst of Infonetics Research and lead author of the report.
"Worldwide CMTS revenue jumped 41 per cent between the first and second quarters of 2003, and we expect it to rise enough to match last year's totals despite rumblings that this was going to be another down year for CMTS."
Infonetics said the top two vendors in the CMTS market, Cisco and Arris, continued to increase their market share.
Cisco now leads, with 41 per cent worldwide port market share and 43 per cent revenue market share. Motorola lies in third place.
"Adding voice and wireless functionality to modems is going to drive cable CPE sales in the coming years," added Richard Webb, Infonetics Research's London-based analyst.
Webb added that cable modems have long been commodity products with thin gross margins, but he predicted an increase in integrating them with routers and wireless/security devices.
Such a trend may inhibit growth in standalone units but could boost sales of multi-functional devices, he added.
"The wireless access gateway market is in its infancy but is now beginning to accelerate significantly, as with all 802.11-based products, particularly in the consumer market," he said.
