Metricom’s Ricochet modem was slated as the first device to offer a high-speed mobile internet connection. This modem worked with laptops and desktops to offer connection speeds of up to 128 KBs per second [!!], producing a connection that was 10 times faster than normal wireless speeds and twice as fast as a normal wired modem at the time it was manufactured. Released in 2000, the Ricochet used radio frequency technology, operating in the 902-928 MHZ range (allowing it to function like a small radio), hopping frequencies with spread-spectrum technology.
The Ricochet modem would transmit data to larger radios that parent-company Metricom had placed in strategic locations in certain cities around the U.S (think lampposts). At least one of the shoe-box sized radios in a 10-mile radius was associated with a T1 or T3 landline, which allowed for the high-speed connection through the device. The Ricochet searched for the nearest available radio, which would transmit the appropriate data to the nearest radio that was connected to a landline.
Why was it better than other wireless modems?
1. This technology would ensure that a user stayed connected no matter what if they were working from a covered service area.
2. The high speed of this technology was a great improvement. Comparable to dual channel ISDN speed in many of the covered cities, this modem provided fast downloading speed to most users.
3. The ‘hopping’ technology also allowed for increased security–it’s a little hard to hack into a system that is changing from frequency to frequency, radio to radio.
4. The cost of this unit (around $100) and the monthly service charge (about $75) was a great deal. The monthly charge covered unlimited usage, which saved users major dough.
Prior to the development of this technology, wireless data could cost up to $25 per MB for downloads at around 10 kbps. Metricom, however, was offering unlimited wireless access at $29.95 (for 28.8 kbps) monthly prior to their new service.
The modem’s power source was a 7.6 VDC, lithium-ion replaceable and rechargeable battery that had up to six hours of juice to keep it going, and it connected to a users PC or laptop through a USB or serial port.
The Ricochet was compatible with Windows 98/2000, Pentium II, MAC 9.0 and PowerPC G3 and G4 and was available in over 35 cities nationwide. Higher speeds were available in hubs like Atlanta, Dallas, Philadelphia and San Francisco, while slower speeds were available in Seattle and Manhattan.
About the size of a small notebook, the Ricochet has a small antenna to pick up the radio signals, weighing in at about 10 ounces.
After going out of business in 2001, the media weighed in on the demise of Ricochet. Some reporters argued that $80 a month for service was outlandish, while others explained that the customer service was poor and that the business model just didn’t work.
