Sony Ericsson's GC85 EDGE laptop card

This is a capable GPRS data card, which will deliver faster near-3G throughput when connected to a network that supports EDGE.

Mobile professionals requiring an always-on data connection when out on the road now have a number of choices of PC Card to use in their notebooks. At the slower end of the spectrum are GPRS and GPRS/HSCSD cards like Vodofone Mobile Connect Card and Sony Ericsson's GC79, which will manage download speeds of up to 56Kbps (that is, dial-up modem speed). The fastest available mobile data cards are the recent crop of 3G products, which claim broadband-like speeds of up to 384Kbps. In the middle is a GPRS/EDGE card such as Sony Ericsson's GC85, reviewed here, which -- on mobile networks that support EDGE (Enhanced Data Rates for GSM Evolution) -- can achieve near-3G speeds of 247Kbps.
