service. It offers up to 25
Mbps speed over the broadband network.
3. Cisco
On March 15, 2000 Cisco
Systems completed its acquisition of Aironet Wireless Communication, Inc, a
company that develops Wireless LAN technologies for all businesses.
- Cisco’s in-building products support 1,2,5 and 11 Mbps
speeds over the 2400-2483.5MHz spectrum
- Cisco’s building-to-building products have a range of up to
25 miles that delivers speeds of up to 11 Mbps that doesn’t require
licensing.
Outside
of Aironet WLAN offerings, Cisco’s other offerings include Cisco WT2700
Wireless Technology Suite. A new broadband wireless solution designed to
enable new opportunities for emerging and competitive service providers by
offering differentiated service in the competitive broadband environment.
Utilizing new techniques in modulation technology, the WT2700 is a broadband
packet-based solution that offers data rates in both traditional
line-of-site operations and obstructed environments never before feasible
for wireless. Up to 44 Mbps of fully duplexed data transfer in
non-line-of-site (NLOS) environments are delivered within an area of
coverage of up to 30 miles.

4. EndGate (www.endgate,com,
408-737-7300)
EndGate makes a complete line
of millimeter-wave wireless access equipment. EndGate’s systems can be
deployed as broadband wireless local loop networks and Internet access
systems in the 32-40 GHz range. Other EndGate systems can be used for
high-capacity point-to-point wireless connections to link different sites or
buildings bypassing more-expensive wireline backbone.
5. Ericsson
(www.ericsson.com)
Ericsson’s
Beewip system is a high performance broadband wireless IP access system
intended for small and medium business customers. It provides “always
on” connection up to 3 Mbps for the end-user. The system offers excellent
use of spectrum and high quality of services. A pilot system is being
installed at Tele2 in Oslo in the ITU standardized 3.5 GHz frequency band.
Beewip
is based on IP and open standards. Beewip is the ideal solution for
residential, small business and home office use, where unrestricted
high-speed access to Internet and other data services are needed.
6. Fuzion
Claimed
by Fuzion to be one of the most advanced and fastest broadband networks
available, Fuzion’s Broadband network is composed of Asynchronous Transfer
Mode (ATM) 25 protocols employing Lucent technology switching and Adaptive
Broadband’s radio equipment (AB Access) components.
- Fuzion cell
site is equipped with at least one full DS3 connected to a Qwest OC-48 fiber
optic backbone.
- Decentralized
architecture designed to eliminate delays inherent in “multiple hops”
and its products eliminate the need for routers and CSU/DSU devices.
- Fuzion
offers FlexBand, MicroBand, MacroBand, PrivateBand and VitalBand products
that can be incrementally upgraded depending on business case.
- Fuzion
products utilize TDD/TDMA traffic management.
7. Lucent Technologies
Lucent Technologies “On Demand” Wireless Access
operates at speeds up to 45 Mbps per link over the air. OnDemand is a highly
dynamic, point-to-multipoint, fixed wireless access network designed for
service providers who own spectrum between 10 and 42 GHz.
It has the following features and benefits:
- A point to multipoint architecture that shares hub costs over
a broad customer base
- An Asynchronous Transfer Mode-based (ATM) Time Division
Multiple Access (TDMA) air interface for dynamic and optimal bandwidth
allocation to different customers in real-time mode
- A programmable modulation schemes for easy capacity upgrades
8. Motorola’s Aspira
Architecture for Broadband
Motorola’s
Aspira architecture conceived in cooperation with Cisco is a blueprint of
wireless Internet with IP implementation. It addresses the market
requirements beyond wireless broadband because it extends the architecture
to IP and internetworking where Cisco is the dominant player. While users
may implement wireless Broadband in isolation to address specific
inter-building connectivity, Aspira architecture and products coming out of
this architecture should be reviewed by telecommunications service providers
and large private network implementers (like Fedex and UPS) on its own
merits.
Motorola
has implemented networks in Japan based on interim implementations of this
architecture. Go to Motorola and Cisco site for more on this architecture.
