2G/3G Indoor Coverage Planning
2G/3G Indoor Coverage Planning Customers of mobile networks expect to have reliable coverage and adequate capacity wherever they are. This means that all operators need to provide 2G and 3G indoor coverage in key locations as a high-priority planning goal. Indoor coverage planning is significantly different from general coverage planning and requires a different skill set. This Wray Castle course provides the extra knowledge and skills that UMTS and GSM cell planners need to expand their capabilities into the
indoor environment. Delegates will learn how 2G and 3G traffic characteristics vary for indoor cells and how this impacts the chosen solution and cell configuration. The course covers indoor propagation prediction and site survey strategies. This leads into coverage techniques based on copper and fibre distributed antenna systems and radiating cables. Delegates will learn how to determine the most appropriate and cost effective coverage strategy in a range of scenarios. This is backed up with case studies and planning exercises.
Who Should Attend This course is designed for planning engineers working for network operators, cell planning consultancies or software tool manufacturers who wish to move into indoor coverage planning. Although most delegates attending this course will have practical planning experience it is possible to progress directly to indoor coverage planning if the theoretical knowledge is in place.
This course is also useful for delegates who will be working in planningrelated areas or who need to understand planning considerations. This includes network management, Government security or forensic work, legal professionals supporting network operators or local authorities, support staff and those managing planning teams.
Learning Objectives On completion of this course the delegate will be able to:
n
explain how repeaters can be used to provide indoor coverage and calculate repeater gain
n
identify effective strategies and general procedures that enhance the indoor planning process
n
n
identify typical 2G and 3G offered traffic levels, blocking limits and characteristics for a range of indoor coverage scenarios
identify indoor coverage scenarios where it would be better to use a dedicated picocell than a repeater
n
n
use Erlang traffic principles to arrive at suitable cell dimensions
discuss the design of passive and active distributed antenna systems and list factors that determine radiated power and noise contribution
n
outline how packet data capacity can be provided in 2G cells with GPRS and in 3G cells with WCDMA and HSPA
n
explain the design of optical fibre for distributed antenna systems and identify advantages in their use
n
describe key propagation effects in buildings, tunnels and sports stadiums and identify where waveguide effects may occur
n
identify indoor coverage situations where leaky feeder can be used and calculate power levels required for leaky feeder systems
n
describe typical statistical and deterministic indoor propagation models and compare their features
n
perform link budget and balancing calculations on typical indoor coverage systems
n
describe how indoor cells can be integrated into the wider coverage network
n
shortening the learning curve and speeding productive inputs from new team members and freeing more experienced employees’ time
n
evaluating better a system’s capabilities through improved knowledge, leading to superior operations and maintenance performance
n
providing greater confidence in the sale of equipment by anticipating customers’ technical requirements and being able to promote relevant superior equipment performance
Benefits In addition to gaining a good understanding of 2G/3G indoor coverage planning, this course will enable the delegate to deliver operational improvements and generate cost savings or reduce project timelines by: n
improving network design, planning, operations and maintenance
n
avoiding the laborious search through specifications, standards and white papers, while benefiting from a practical analysis and interpretation of such documentation by experienced engineers
n
knowing better where to look to accelerate research and fact finding and facilitate earlier project completion
n
improving the equipment procurement process by better analysis and challenge of technical specifications and supplier responses, thus giving greater certainty to on-target performance and value-for-money purchasing
and, after the course, Wray Castle’s unrivalled post-course support comes into effect.

Prerequisites
Searchable, Full-Colour Notes on CD
Ideally, delegates will have a good understanding of UMTS and GSM air interface operation and an appreciation or experience of cell planning for both technologies. For delegates without this prerequisite knowledge, attendance on our UMTS Air Interface, GSM Air Interface, Cell Planning for UMTS Networks and Cell Planning for GSM Networks courses is strongly recommended.
Along with a paper copy of comprehensive course notes the delegate will receive an electronic version on CD. This provides delegates with an easily transportable and fully searchable reference tool, including all the colour detail of the course presentation.
Follow-on Training
Technical Level 3 This course has been developed for engineering staff requiring detailed knowledge of a specialist area of technology. It assumes some underlying knowledge in broader, related topic areas on which the detailed content is built. It also assumes general engineering skills and knowledge appropriate to the course topic.
Delegates may wish to extend their planning skills into optimization by attending the Introduction to GSM Optimization, Introduction to UMTS Optimization and Cell Planning for LTE courses. Others may extend the range of their knowledge of radio access technologies with the HSPA Principles and Application or our WiMAX courses. TCP/IP Protocol Suite or MPLS Overview may interest those involved in terrestrial communications links for radio.
