Still, many people face communication problems due to weak or inconsistent signals, especially inside buildings where walls, electrical devices, and other obstacles interfere with connectivity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At UCtel, we specialise in helping organisations overcome connectivity challenges. Our team utilises advanced CEL-FI signal boosters and proven methodologies to assess mobile network performance, identify weak spots, and recommend tailored solutions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we\u2019ll break down the ways to check mobile signal strength and improve connectivity in your building. Let\u2019s hit the ground running!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Makes a Good Mobile Signal Strength?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The best way to test cell coverage in a building is to determine its decibel-milliwatts, or dBm for short. Thus, mobile signals are basically radio waves operating within specific frequencies, where strength can range from -30 dBm (the best) to -120 dBm (almost no signal\/dead zones).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Any signal stronger than -107 dBm is considered usable, and it\u2019s rare to find something more potent than -50 dBm in the telco market. Typically, from -115 dBm downwards is useless, as calls would drop, data speed would be painfully slow, texts would take a long time to send, and videos buffer. Around -120 dBm, it is pretty much dead.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are signal ranges and what to expect from each:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Signal Strength (dBm)<\/strong><\/td><td><strong>Expected Result<\/strong><\/td><\/tr><tr><td>-50 to -79<\/td><td>Excellent <\/td><\/tr><tr><td>-80 to -89<\/td><td>Good <\/td><\/tr><tr><td>-90 to -107&nbsp;<\/td><td>Average <\/td><\/tr><tr><td>-108 to -114<\/td><td>Poor <\/td><\/tr><tr><td>&lt; -120<\/td><td>Dead<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Important<\/strong>: This chart is a benchmark. Every carrier has its own dBm to bars conversion standards.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Factors Influencing Signal Strength<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Certain factors can influence the strength of a signal inside a building, which usually include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Weather conditions<\/strong> like storms, rain, and fog distort mobile signals.&nbsp;<\/li>\n\n\n\n<li><strong>Radio frequency interference<\/strong> from wireless technologies such as microwaves, cordless phones, and other appliances reduces signal strength.&nbsp;<\/li>\n\n\n\n<li>The <strong>height of a building, its layout, and building materials<\/strong> like concrete and steel can obstruct signals from reaching devices.&nbsp;<\/li>\n\n\n\n<li><strong>Being too far from the nearest cell tower<\/strong> will result in far-from-optimal connectivity.<\/li>\n\n\n\n<li><strong>Increased user volume <\/strong>in office buildings and densely populated areas causes network congestion.<\/li>\n\n\n\n<li><strong>Physical obstructions<\/strong> and other potential interference sources like trees, other buildings, mountains, etc., block mobile signals.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you measure the mobile signal strength of a building, and it doesn\u2019t hit the benchmark because of one of the above reasons, you absolutely need a mobile phone signal booster or its alternatives. Boosters <a href=\"https:\/\/www.uctel.co.uk\/blog\/bad-signal-commercial-spaces\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>eliminate signal dead zones<\/strong><\/a> and improve its strength to a level of -100 dBm or higher.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Measure Mobile Signal Strength<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Simply access your mobile device\u2019s \u201cfield test mode\u201d to test phone signal strength in decibel-milliwatts. This can be found in the \u201cAbout phone\u201d or \u201cNetwork\u201d settings for Android or by typing in a *#*#4636#*#* code for iPhone. DBms will be represented as RSRP signal strength. But of course, it's more of a DIY method, and you will require professional testers for more precise measurements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But, whatever you choose to check mobile phone signal strength, it\u2019s crucial to know how to accurately take measurements to reflect the true state of a mobile network in your building. So, here are our best practices for how to check phone signal strength and provide proper in-building mobile signals in new and old commercial properties:&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Test signal strength at different points in the building<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Testing signal strength at different pivotal points in a building is also known as grid testing. Test mobile signal strength for the building, highlighting spots where calls frequently drop and areas where people go to make uninterrupted calls. We recommend walking around the property to note areas where you tend to lose network coverage and map them out.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taking several dBm readings and then comparing them is one of the most effective methods for how to check signal strength. Consider getting an expert onboard to properly access your building\u2019s coverage loopholes, simulate emergencies, identify the specific culprits causing poor connectivity inside the building, and determine how to fix the problem.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Grid testing is vital for robust mobile coverage in building areas with signal-related issues and interference.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Test one network at a time<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Wondering <a href=\"https:\/\/www.uctel.co.uk\/blog\/6-reasons-why-4g-mobile-connection-is-slow\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>why your 4G is so slow<\/strong><\/a> while 5G works perfectly? Some networks provide better 4G or 5G coverage in some areas. Therefore, it\u2019s essential to test mobile signal strength across all carriers. Identifying gaps in their coverage is critical, especially in commercial buildings, where there may be more areas with weak signals than strong ones.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Forget the bars<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The mobile signal bars in the upper right corner of your mobile device are mostly there as a visual representation of a mobile connection. It\u2019s basically the Joe Bloggs of signal strength testing and doesn\u2019t paint the full picture. While bars are an easy point of reference for laymen, they can vary greatly and often depend on the phone manufacturer and carrier network.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Generally, a full bar doesn\u2019t equate to great coverage, and it\u2019s recommended to ignore the bars when you check phone signal strength in office buildings or for your commercial property.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Face important key performance metrics<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">One important KPI to monitor when accessing a building\u2019s signal strength is the radio frequency quality. Many factors like weather, network congestion, and more will affect network quality. From our experience, one of the most common determinants of signal strength is RF interference. Therefore, learning how to perform a phone signal test in a building without spectrum analysis is a waste of time. It involves identifying these RF factors, such as trees, building materials, and other signal degradation sources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Book a professional survey<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you're asking yourself, \u201cHow do I test my phone signal?\u201d, DIY testing can indeed provide valuable insights. Yet, a professional mobile signal survey offers a more comprehensive and accurate evaluation of your building\u2019s connectivity landscape. At UCtel, we conduct in-depth surveys to identify and address signal strength issues by:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Using advanced tools like analysers and spectrum scanners;<\/li>\n\n\n\n<li>Testing signal strength at multiple points, including hard-to-reach areas;<\/li>\n\n\n\n<li>Measuring critical metrics like RSRP, SINR, and RSRQ for each carrier;<\/li>\n\n\n\n<li>Providing a detailed report that highlights signal strength, quality, and coverage gaps throughout your building, along with visual maps and actionable insights.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to Provide Robust Mobile Signal Strength for Office Buildings&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once you\u2019ve tracked down your building\u2019s signal strength, it\u2019s time to start exploring solutions for providing robust mobile signal strength in office buildings and commercial properties.

Private 5G network<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">5G is the future of wireless connectivity, which is slowly being rolled out in every part of the world. However, you can take matters into your own hands by adopting a <a href=\"https:\/\/www.uctel.co.uk\/private-5g-networks\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>private 5G network<\/strong><\/a>, which is similar to the public 5G network but allows owners more control over it. This next-gen dedicated private network has wide and deep coverage, low latency, strong security, and is easy to deploy. This is a robust solution for every commercial building, such as hospitals and factories, that rely on fast and reliable networks for smooth operation.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When to Seek Professional Help for Phone Signal Strength Issues<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing when to call in experts can save time, effort, and money while ensuring reliable and long-lasting solutions to your connectivity problems inside commercial or residential buildings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Persistent issues beyond DIY fixes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019ve tried repositioning your devices, installing signal boosters yourself, or even moving to areas with fewer obstructions, but the problems persist, this indicates more complex issues, such as poor network infrastructure in your locality or incorrectly configured boosters and repeaters. In this case, professionals can conduct an in-depth analysis of the signal environment, identify root causes, and implement effective solutions tailored to your specific needs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Need for comprehensive signal surveys<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If you wonder how to check signal strength of all available network operators in your area to optimise connectivity inside your building, professional signal surveys provide a detailed assessment of signal strength, interference levels, and dead zones throughout your space. You\u2019ll also get data-driven recommendations for the optimal placement of signal-enhancing equipment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Complex environments<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In commercial, industrial, or large residential buildings, multi-story offices, or facilities with unique layouts, measuring mobile signal strength and achieving its consistency is a challenging task. Specialists have the required knowledge and expertise not only to do precision testing and detect major causes for poor signal but also to design custom solutions that will really help.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When reliable communication is critical<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In businesses like healthcare, finance, or customer service, uninterrupted communication is non-negotiable.
