Golden rule: Measure with doors open/closed, elevator shafts, and stairwells – these are usual weak spots.
Scenario: A 1990s concrete building with poor macro signal. Legacy 2G microcells exist but no 3G/4G inside. Users complain of dropped calls in elevators and slow data near windows (macro interference).

Results after deployment:
Indoor radio planning for 2G, 3G, and 4G in 2015 required a delicate balance: maintaining legacy voice coverage (2G), supporting soft handover efficiency (3G), and delivering high-throughput MIMO (4G). While 5G has since introduced mmWave and massive MIMO, the principles of link budgets, propagation modeling, and DAS design laid out in guides like this remain timeless.

The book "Indoor Radio Planning: A Practical Guide for 2G, 3G and 4G" (3rd Edition, 2015), authored by Morten Tolstrup and published by Wiley, serves as a comprehensive manual for engineers and practitioners specializing in Distributed Antenna Systems (DAS) and in-building wireless coverage. This edition specifically expands on 4G LTE, Passive Intermodulation (PIM), and Multiple-Input Multiple-Output (MIMO) systems. Core Concepts and Planning Stages
Radio planning for indoor environments focuses on delivering adequate coverage, capacity, and service quality through three primary phases:
Dimensioning: Determining the initial resources needed to meet coverage and traffic requirements.
Detailed Planning: Designing the specific layout of antennas and equipment.
Optimization: Fine-tuning the network post-deployment to resolve interference or performance gaps. Key Technologies Covered
The guide bridges multiple generations of cellular technology, each presenting unique indoor challenges:
2G (GSM): Primarily focused on voice and basic data (GPRS/EDGE). Results after deployment : Indoor radio planning for
3G (UMTS/HSPA): Introduced higher data speeds up to 42Mbps, requiring more complex capacity planning.
4G (LTE): Focuses on high-speed mobile broadband, necessitating advanced antenna systems like MIMO and strict noise analysis. Distributed Antenna Systems (DAS) Architecture
A significant portion of the guide is dedicated to DAS, which distributes the cellular signal throughout a building via a network of antennas:
Passive DAS: Uses passive components like coaxial cables, splitters, and couplers.
Active DAS: Utilizes electronics to boost signals over fiber or Ethernet, making it suitable for very large structures.
Hybrid Solutions: Combines elements of both for cost-effective performance in medium-to-large buildings. Practical Planning Tools and Calculations
Engineers use the guide to perform critical technical assessments, including: Disclaimer: This article is an original educational summary
Link Budget Calculations: Estimating signal loss from the source to the end-user. Traffic Analysis: Predicting user density and data demand.
Interference Modeling: Calculating C/(I+N) (Carrier to Interference plus Noise) ratios to ensure signal clarity.

A robust indoor plan starts with a link budget per technology.
Sample Calculation for LTE 1800 MHz (4G) indoors:
Then, using the indoor path loss model (e.g., COST 231 Multi-wall):
PL (dB) = 32.4 + 20*log10(f) + 20*log10(d) + Σ (Lw * Nw)
