The LMS4000 900MHz Radio Network, which operates in the 900MHz ISM band, offers the
following features and benefits:
• Excellent Propagation Characteristics: LMS4000 900MHz radio networks provide
excellent coverage to non-line of sight installations using WaveRider’s proprietary
indoor diversity antenna and extended coverage to installations using external high-
gain antennas.The 900MHz ISM band is more suited to NLOS (non-line of sight)
wireless Internet applications than other ISM bands because it has superior
propagation performance, demonstrating the following benefits:
• Lower free-space, cable and foliage loss
• Better wall and glass penetration
• More signal recovery from diffraction and reflection
• High-speed Channel: The LMS4000 900MHz Radio Network provides a raw channel
bit rate of 2.75Mbps, which translates to peak FTP rates of 2Mbps.
• High-performance Polling MAC: WaveRider’s patented Polling MAC algorithm
takes advantage of typical usage patterns found in Internet transactions, such as Web
browsing and email, to provide an operating capacity of up to 300 end users per RF
