The extended channel lengths over which the ZinWave 2700 DAS operates using these cabling systems (see 2.4)
93
enables centralised location of all equipment within even the largest buildings. This in turn:
94
•
provides enhanced network security by allowing all vulnerable devices to be placed in one secure location;
95
•
reduces equipment and support costs;
96
•
provides the ability to remotely maintain and upgrade WLAN APs etc.

The components
100
The ZinWave 2700 DAS units are:
101
•
the ZinWave
2700 Hub Unit (HU):
which comprises a ZinWave 2700 Hub, a stackable 1U high 19” rack mount
102
device, supporting four independent RF (370 - 2500 MHz) service inputs/outputs, together with up to eight ZinWave 2780
103
Small Form Pluggable (SFP) optical fibre transceiver modules (see clause 3.1);. Each ZinWave 2780 SFP module
104
supports a ZinWave 2760 antenna unit
105
•
the ZinWave
2760 Multi-service Antenna Unit (AU):
a small enclosure designed for unobtrusive installation with
106
separate antennas in an office environment
107
•
the ZinWave
2776 Narrow-band Antenna Unit (AU):
a wall-mounted enclosure designed for installation with a
108
separate antenna in an office environment.

The technology
112
ZinWave’s patented technology renders conventional MMF a practical transmission medium for wideband, high
113
frequency, radio frequency (RF) signals by extending the bandwidth of legacy, in-situ, cabling to permit the transmission
114
of multiple RF signals, supporting different services, at original carrier frequency over long distances using low cost
115
uncooled transceivers.
116

2.4
The system
119
The ZinWave transceivers within the hub and antenna units are “fibre agnostic” i.e. they can be used with either 50/125
120
mm or 62.5/125
µ
m MMF. ZinWave 2700 channels can be up to 550 metres long provided that the MMF cable has a
121
modal bandwidth of at least 500MHz.km @ 1300 nm.
122
123
This length of channel is more than adequate to facilitate a high quality, broadband, in-building coverage extension
124
system for multiple, simultaneous wireless feeds for 2G/3G Base stations, WLAN APs, TETRA etc
125
126
Without ZinWave’s technology, such distances can only be achieved in most scenarios by expensive re-cabling of
127
buildings using coaxial cables or single mode optical fibre, or by reverting to narrowband techniques which restrict the
128
systems’ capability.
129
130
The ZinWave DAS is ideally suited to applications where multiple cellular and/or WLAN services are required and can be
131
easily configured for various deployment scenarios such as .at campuses, large high-rise buildings and multi-tenanted
132
units.
133
134
NOTE:
In the US and Canada, only the use of the Cisco® Aironet ®1200 WLAN access point (Model AIR-AP1231-A-K9) is
135
approved for connection to the 2700 hub for providing WLAN services.
136
137
NOTE:
Optimal performance of the ZinWave 2700 DAS may require the re-termination of the optical fibres within legacy
138
multimode optical fibre infrastructures installed using components meeting the above mentioned standards. This is
139
dealt with in detail in clause 4
140
141
NOTE:
Channels lengths of up to 2000 metres can be delivered, using the same 2700 System components, over SMF cabling.

Integrated management software
145
Management of the ZinWave 2700 system is implemented by proprietary software which allows remote configuration via
146
the World Wide Web, Telnet and/or SNMP. The management system allows Hub and Antenna Unit health monitoring
147
and provides a flexible approach to both RF to Transceiver Distribution (see 4.8) and Gain Mapping (see 4.9).
