In-Building Wireless Network Design Services

Today's wireless world is comprised of PDAs, WLAN, Wi-Fi, 2-way radio, wireless phones, pagers and wireless laptops. Such equipment creates an ever-growing challenge to the IT and Telecom managers. With nearly a decade of wireless technology, application, design, and installation expertise, WG is uniquely qualified to provide the right solution based on your industry requirements.

  • Circles on the floor plan do NOT represent RF propagation and coverage accurately 
  • CAD software based solution provides a much more precise design approach 
  • Software simulated RF propagation/coverage is 95% accurate and over 70% less time consuming

 

WLAN Survey

 

Cellular Bi-directional Amplification is very important for any municipal, business and educational facility that has no in-door coverage. 

WG design engineers utilize the facility's floor plans and data from a pre-installation survey to create a detailed system design from a computer-generated model that predicts the RF propagation within the facility. A link budget is also included with the design that depicts power levels throughout the system, identifies cable routes and equipment locations, and provides an uplink noise analysis. Typical systems are designed to achieve a -85 dBm or better throughout 95% of the required coverage area unless otherwise specified.

 

Standard Procedures 

During the initial system design, several basic decisions must be made regarding the type of equipment and the configuration which is to be employed. However, before these decisions can be made it is first necessary to establish the volume and type of traffic to be transmitted and where it is to be terminated. It is important that not only the initial traffic requirements be considered but also the needs for future growth. Inaccurate growth forecasting can result in an excessive initial investment if the growth is overstated . Alternatively, predictions, which are too small, can necessitate expensive modification or expansion of the system soon after it is operational. 

Usually one of the first decisions which is made is whether the system will employ analog or digital techniques. Most new routes will favor the use of digital radio equipment, since this design offers greater economy and flexibility for the transmission of digital data traffic; a feature which will become increasingly important in the future. Early digital microwave systems were very limited in the amount of traffic, which could be accommodated within a given band, but with improved, and more sophisticated modulation techniques this factor is becoming less of a consideration. Even when voice or other analog traffic is predominant, the relatively low cost of pulse code modulation multiplexing equipment, when compared to frequency division multiplexing equipment, will often favor the use of digital radio. However, analog radio may be more desirable if there is a requirement for carrying video signals or if a very high concentration of voice circuits are needed, such as may be necessary for a long-haul telephone system. 

The next step in the preliminary planning should be to decide on the degree of reliability or availability which the system is required to yield. Most non-technical people posed with such a question would probably respond with answers like: "The best possible, " "It must always be available when needed," or possibly "Communications are vital to my business and no service interruptions can be tolerated." Unfortunately, these answers are of little value or help to the microwave system design who requires a specific numeric value upon which to base the design. The appropriate selection of this value is of paramount importance, since it will affect many subsequent design decisions and the over-all cost of the system. 

Table 1 provides the relationship between reliability and outage time, but it is almost impossible to predict the duration and frequency of each individual outage, which will contribute to this total value. Further, the outage time will be composed of two different reliability figures. Equipment malfunctions can be expected to be relatively rare, particularly if standby assemblies are furnished, but may be of long duration. If the microwave station is remotely located, it may take an hour or more to dispatch a technician and remedy the fault. Service interruptions due to propagation conditions will be more frequent but of short duration—typically a few seconds. The permissible outage time will affect such factors as: 

  • Operating frequency band
  • Maximum path length
  • The need for diversity
  • Equipment failure protection
  • Antenna size
  • Transmitter output power
  • Equipment selection

 

The major factors which influence the choice of the frequency band in which the proposed microwave system will operate are: 

  • The required traffic capacity
  • The classification of the user
  • The length of the path
  • Frequency congestion in the area
  • Weather conditio

 

Table 1: relationship between reliability and outage time 

Reliability % Outage time % Outage time per year
0 100 8760 hours
90 10 8760 hours
98 2 175.2 hours
99 1 87.6 hours
99.9 0.1 8.8 hours
99.95 0.05 4.4 hours
99.99 0.01 53 minutes
99.995 0.005 26 minutes
99.999 0.001 5 minutes
99.9999 0.0001 32 seconds

 

The objective of path is to design a microwave system that meets system traffic and reliability requirements at a minimum cost. The final system path design documentation contains:

 

  • Structure types and heights
  • Site layout reports
  • Site acquisition reports
  • System transmission design

 

Customer Quotes


Pyramid Lake Paiute Tribe

"WirelessGuys' work was very timely. They worked quickly through any issues that came up and got everything done right and on time. Some companies throw their hands up when they run into obstacles. WirelessGuys tackled the issues, worked through them and still finished in a timely manner. They also brought significant expertise to our project in terms of their antenna and cabling work as well as their advanced project management skills."

Sober Living by the Sea

"After speaking with Steven Williams and his team, their expertise and technical know-how was very apparent. They basically sold themselves. During the installation, I was quite pleased with the knowledge, project management skills and technical know-how they brought to the table."
