In compliance with new FCC rules, Aperto Networks began shipping broadband wireless access systems in the overlapping 5.8 GHz U-NII and ISM bands. The new FCC rules (Part 15.247) allow the use of additional digital modulation techniques in the ISM band and thus enable higher peak usable power for 5.8 GHz non-spread spectrum wireless access systems than for U-NII systems. Aperto said the enhancements more than double the coverage footprint for carriers. The improved coverage comes from a combination of higher power radios that increase cell radius from 5 to 8 miles, 20 Mbps capacity in a narrow 6 MHz channel size, and improved interference resilience that enables multiple service providers to operate in the same area. Aperto said that by operating in the 5.8 GHz ISM band, it is boosting available spectrum by 25%, an increase from 16 to 20 non-overlapping 6 MHz channels, versus the typical competitive norm of 5 wide channels.

- Aperto Networks offers point-to-multipoint PacketWave base stations, subscriber units, and associated radios and antennas in 2.5, 3.5, 5.3 and 5.8 GHz frequency bands. Aperto’s base station leverages advanced TDMA and bi-directional burst mode transmission to operate with adaptive TDD or FDD radios.
- Last month, Aperto introduced a new carrier class point-to-point wireless bridge that could be used as an alternative to leased T1/E1 connections for providing Wi-Fi hotspot backhaul. The PacketWave 600 Series Wireless Bridge provides a dedicated air interface at a 20 Mbps data rate to locations as far as 30 miles (48 km) from the carrier’s wireless base station.
- Aperto Networks is a start-up based in Milpitas, California. The company has raised $57 million in funding.
