System
Introducing the WaveACCESS NET Product
Family
The WaveACCESS NET system is a radio-based, high-capacity, high bit rate, low-cost packet switched wireless system that operates in the 2.4 Ghz ISM unlicensed band to provide point-to-multipoint wireless Internet access. It is designed to provide communications for several hundred users simultaneously accessing the Internet or intranet.
WaveACCESS NET employs Frequency Hopping SpreadSpectrum (FHSS) technology at data rates of 3.2 and 1.6 Mbps. The fully digital FHSS radio provides protection against interference and enables operation of collocated systems, thereby increasing overall data throughput. WaveACCESS NET has been optimized for IP traffic and provides high-speed networking at distances of several miles.
The WaveACCESS NET system consists of a central site known as the base station, and up to several hundred remote sites. The base station is where the system links to a backbone, for example, telephony, satellite, wireless, or digital cable data transmissions. The WaveACCESS NET CU232 sits at the base station.
The remote sites are the user locations, where remote WaveACCESS NET xDR232 units act as LAN adapters.

WaveACCESS NET 2400 Installation Guide |
Introducing the WaveACCESS NET 2400
System
The WaveACCESS NET system is comprised of the following:
■WaveACCESS NET CU232: A wireless point-to-multipoint central unit that can support up to 60 remote units at a data rate of 3.2 Mbps each. Using unique RFStacker™ technology, up to ten WaveACCESS NET CU232 units can be collocated in a single site, creating a cell of up to 600 remote units at a data rate of up to 25 Mbps. A remote unit does not necessarily indicate a single user (for example, an MDR232 can support an entire LAN). Therefore, the actual number of users the WaveACCESS NET CU232 is able to support is considerably higher than the number of remote units.

System
■WaveACCESS NET SDR232: A standalone wireless LAN adapter (remote unit), including a built-in antenna, designed to connect to any computer’s Ethernet adapter card and allow fast linking of any workstation to the Internet or Intranet. This allows the user access to the full bandwidth, without having to share the capacity with multiple users on a network.
Figure 1-2 WaveACCESS NET xDR232
■WaveACCESS NET MDR232: A multidrop remote unit, including a built-in antenna, that provides a bridging function and enables a complete LAN to be connected over a wireless network. This unit has particular application for a small office environment, in which a single MDR232 would enable all the computers to access the Internet.

Sectorization of the Central Site
WaveACCESS NET CU232 units are typically installed in business or residential areas which do not have well-defined boundaries. It is not always possible to place the base station, with the central units and antennas, in the optimal location. Therefore, the WaveACCESS NET system provides the ability to sectorize the base station by using multiple CU232 units, each of which covers a sector of the total area to be covered.
This allows an increase in cell range from approximately two miles, for an omnidirectional 8dBi antenna, to approximately seven miles for a 20dBi panel antenna.
If you have many users in one area, you may have more than one CU232 covering the same area to provide optimal throughput for all the users.

Introducing the WaveACCESS NET 2400
System
WaveACCESS NET Ruggedized Unit
The WaveACCESS NET 2400 units are fully ruggedized and suitable for outdoor installation, in weather conditions of -40°C to 55°C.
An internal antenna is embedded in each unit, although there is also an option to use an external antenna for wider coverage. A single flexible cable is used to transmit data and supply the unit’s power. The WaveACCESS NET 2400 product now includes a power/data adapter that connects to the AC power supply directly and provides an Ethernet connection.
While the WaveACCESS NET 2400 system is fully compatible with the previous WaveACCESS NET version, it provides enhanced functionality, as follows:
■Firstly, the fact that the unit is ruggedized and has an embedded antenna precludes the need for a long RF cable connecting the indoor unit to its external antenna (with its inevitable losses). Thus, the signal quality and the effective ranges are improved.
Increased maximum range enables ISPs to accommodate more users with a higher data rate in that cell and at the same level of service. This benefits both ISPs and users of the system, as users with a low data rate use more bandwidth when transmitting the same data, than users with a higher data rate.
■Secondly, the WaveACCESS NET 2400 units custom cable connects to both the AC power supply and the Ethernet via a single box, as opposed to the two boxes (one each for power supply and Ethernet) in the previous version. The cable itself is thin and easy to manipulate and enables the unit to be placed up to 100 meters from the power supply.
■Thirdly, the WaveACCESS NET 2400 is easier to install.

Preparation
Tower Pipe Installation
It is recommended that towers have a wind rating of 100mph with 5, 10, or 15 CU232s. Each CU232 will experience 80 kg (175 lbs) of wind load at 100mph w/wind factor normal to CU232. The tower should be able to support 1, 2, or 3 sets of CU232s.
The installation height of the antenna must be approximately 15 m above the surrounding average building height, or as specified by the field RF engineer.
The pipes to which the CU232s will be attached should be mounted either on a tower, or on the sides of a building near the roofline, at a height specified by the field RF engineer.
When tower installation is performed, the pipe should be installed around the tower with an angular separation of 72 degrees. In certain instances, it may not be possible to install the support pipe at 72 degree intervals. The ability to swing the CU232 from side to side over an arc of approximately 45 degrees is required. One of the support pipes should be mounted on the tower so that it faces North. A subsequent pipe can then be installed at 72 degree increments from the reference Northward facing pipe.
When performing the installation of five CU232s on a building, the support pipes should be located on a common wall. The other three CU232s can be installed on the other three sides of the building. The clearance requirements should comply with
Figure 2-1.
The minimum distance between any CU232 support pipe and other wireless telecommunication equipment should be
two meters.

Electrical Power Requirements
This section provides guidelines for the installation of AC or 48VDC electrical power to the base station, as follows:
■General Requirements, page 2-7.
■CU232 Power Requirements, page 2-7.
General Requirements
All the AC wiring and over-current protection must be provided in accordance with the National Electric Code (NFPA-70) and local electrical codes. An appropriate earth-ground connection is required before the commercial AC service can be connected. The base station AC input power is single phase, nominal 120/208 or 120/240 Vrms, 50/60 Hz. Nominal voltage is defined as 120 Vrms between line(s) to ground, and 208 Vrms or 240 Vrms line to line.
CU232 Power Requirements
Each CU232 requires 24-48VDC, 15 Watts, which is supplied by the power/data adapter.

Grounding and Lightning
Protection Bonding Requirements
This section provides information on grounding and lightning protection requirements for a WaveACCESS NET base station, as follows:
■General Requirements, page 2-7.
■Lightning Protection, page 2-10.
General Requirements
The WaveACCESS NET base stations are susceptible to lightning surges due to their association with towers and antennas. Therefore, it is imperative that all base station components be properly grounded, providing a low impedance path to earth. The grounding conductors must be as straight and short as possible and should not have any sharp bends or loops.
The CU232 cable shield must be bonded at the top and bottom of the vertical run, and where it comes near the equipment. The tower or metallic support of the antenna must also be bonded to the grounding system. In addition, the surge protection device must be bonded to a nearby ground bus bar that is connected directly to the grounding electrode system.
All metallic objects within 2 meters (6 feet) of the grounded equipment must be bonded to the grounding system.
All base station equipment must be bonded to a grounding electrode system, for example, buried ring ground, copper clad rod, electrolytic rods, metallic water pipe, and so on.
2-8 |
WaveACCESS NET 2400 Installation Guide |
WaveACCESS NET 2400 Base Station Site
Preparation
The minimum requirement for buried ground conductors is #2 AWG bare, solid, tinned copper wire. Exterior ground
conductors must be either solid, bare, tinned copper or stranded, insulated (for sunlight resistance) copper cable. The interior ground cable must be stranded copper with green insulation type THAWN or equivalent.
All grounding system material, namely, cable, connectors, buses, and so on, must be made of high quality materials that are resistant to deterioration and that require little or no maintenance.
An exothermic weld is recommended for grounding connections, where practical. All below-grade connections must be exothermically welded. In addition, compression type, long barrel, two-hole (0.75" center) lugs or double crimp “C” Taps are also acceptable. The metal contacts to which connections are made must have a bare bright finish, and be coated with an anti-oxidation material.
Refer to Lucent Technologies 401-200-115, Grounding and Lightning Protection Guidelines for Wireless System Base Stations, for detailed requirements regarding grounding and lightning protection bonding.
!WARNING:
The equipment warranty can be voided if the guidelines detailed in the National Electric Code (NFPA 70), Standard for Installation of Lightning Protection System (NFPA 780, 1995 edition), Lucent Technologies 401-200-115, and Lucent Technologies Equipment Drawings referred to in this document are not followed.
Refer to Appendix C for a checklist of the verification of the grounding requirements that can be performed.
