5G FAQ

5G differs from 4G in several fundamental ways beyond just speed. While 4G LTE offers peak speeds of around 1 Gbps, 5G targets up to 20 Gbps. Latency drops from 30–50 ms on 4G to as low as 1 ms on 5G, which is critical for real-time applications.

Architecturally, 5G uses a cloud-native core network (5GC) rather than 4G's Evolved Packet Core (EPC). 5G introduces network slicing, which allows a single physical network to run multiple virtual networks with different performance characteristics. 5G also uses a wider range of radio frequencies — including millimetre wave spectrum above 24 GHz — and advanced antenna technologies like Massive MIMO and beamforming that were not part of 4G standards.

The main benefits of 5G fall into three categories aligned with its three service pillars. First, for consumers, 5G's enhanced Mobile Broadband (eMBB) capability means significantly faster internet speeds, support for high-quality video streaming, augmented reality, and reliable connectivity even in crowded venues like stadiums and airports.

Second, for industry, Ultra-Reliable Low-Latency Communications (URLLC) enables new applications such as remote industrial automation, real-time machine control, autonomous vehicles, and telemedicine — applications that were impossible over 4G due to latency and reliability limitations. Third, for the emerging IoT ecosystem, Massive Machine-Type Communications (mMTC) allows billions of low-power sensors and devices to maintain reliable connectivity with minimal energy use, enabling smart cities, environmental monitoring, and precision agriculture.

In mobile telecommunications, a "generation" refers to a major revision of the international mobile standard, typically defined by a new set of performance targets and technical specifications. Each generation introduces new radio technology, network architecture, and capabilities. The first generation (1G) introduced analogue voice calls in the 1980s. 2G brought digital voice and SMS. 3G introduced mobile internet. 4G LTE enabled broadband mobile internet. 5G extends this with ultra-high speed, ultra-low latency, and massive connectivity.

Generational standards are set by international bodies — primarily the ITU (International Telecommunication Union) and 3GPP (3rd Generation Partnership Project) — ensuring global interoperability so that 5G devices and networks from different manufacturers and countries work together.

5G works by transmitting data over radio frequency (RF) spectrum using a digital encoding standard called 5G NR (New Radio), specified by 3GPP. User devices (called UE — User Equipment) communicate wirelessly with 5G base stations (called gNBs — next-generation Node Bs) using OFDM (Orthogonal Frequency Division Multiplexing) waveforms.

The base stations are connected to the 5G Core (5GC) network via high-speed backhaul links (typically fibre optic). The 5GC handles authentication, session management, and routing of data to and from the internet or private networks. Key enabling technologies include Massive MIMO (using tens to hundreds of antennas per base station), beamforming (directing radio energy toward specific users), and flexible spectrum use across low, mid, and high frequency bands. For a detailed explanation, see our How 5G Works page.

5G operates across three broad frequency ranges. Low-band 5G uses frequencies below 1 GHz (such as 600 MHz and 700 MHz), providing wide-area coverage similar to current 4G but with 5G capabilities. These signals travel far and penetrate buildings well but offer limited bandwidth — typically 100–300 Mbps in practice.

Mid-band 5G, particularly around 3.5 GHz (the n77/n78 band), is the global workhorse of 5G deployments. It balances coverage (several kilometres per cell) with throughput (300 Mbps to 3+ Gbps) and is the primary band used for 5G in most urban areas worldwide. High-band 5G — known as mmWave — uses frequencies from 24 GHz to 100 GHz, offering extreme throughput (potentially 20 Gbps) but very short range (typically under 300 metres) and poor building penetration. mmWave is used in specific high-density hotspot scenarios.

Network slicing is a cloud-native capability introduced with the 5G Core that allows a single physical network to be logically divided into multiple independent virtual networks — called "slices" — each configured with specific performance characteristics.

For example, a network operator could create one slice with ultra-low latency and high reliability for an autonomous vehicle application, another slice with high bandwidth for video streaming, and a third slice optimised for low power and large device count for IoT sensors — all operating simultaneously on the same physical infrastructure. Each slice is isolated from the others, ensuring that one application cannot degrade another's performance. This makes 5G far more versatile than previous networks, which could not differentiate performance by application type.

Non-Standalone (NSA) 5G uses an existing 4G LTE core network as its anchor — the 5G radio access is added on top of 4G infrastructure. This allows faster and more economical rollout since operators reuse their existing core network investment. NSA provides higher speeds than 4G but does not unlock all 5G features such as network slicing or ultra-low latency URLLC, because it still relies on the 4G core's architecture.

Standalone (SA) 5G deploys a complete 5G Core (5GC) network alongside the 5G radio access. SA mode unlocks the full 5G feature set including network slicing, edge computing, ultra-low latency for URLLC applications, and the complete separation of user and control planes. SA is the target architecture for advanced 5G deployments but requires greater infrastructure investment and migration from existing 4G core networks.

Yes. Oman has seen 5G network rollouts across major urban areas. The Sultanate's telecom sector is regulated by the Telecommunications Regulatory Authority (TRA) of Oman, which manages spectrum licensing and network standards. 5G deployments in Oman have followed the global pattern of beginning in major cities such as Muscat and progressively extending coverage.

This website is an independent educational resource and does not track or report on the specific coverage areas, speeds, or status of any particular operator's 5G network. For current coverage information, we recommend consulting your mobile operator directly.

Oman's diverse geography has a significant impact on 5G network design and coverage. The coastal urban areas around Muscat benefit from relatively flat terrain and high population density, making them ideal for mid-band 5G deployments with dense infrastructure. The Al Hajar mountain range creates propagation shadows that require careful site planning, and some remote mountain communities may rely on low-band 5G or non-5G connectivity for an extended period.

Oman's vast desert interior presents large areas of open, flat terrain that is physically ideal for radio propagation but economically challenging to cover due to low population density. The country's extensive coastline creates unique propagation conditions where signals can reflect off the sea surface. For an in-depth analysis, visit our Network Environment page.

Telecommunications in Oman are regulated by the Telecommunications Regulatory Authority (TRA), which operates under the Ministry of Transport, Communications and Information Technology. The TRA is responsible for issuing spectrum licences, establishing technical standards for network deployments, enforcing quality of service requirements, and protecting consumer interests in the telecom sector.

The TRA's framework aligns with international ITU standards, ensuring that Oman's 5G deployments conform to global technical specifications. For regulatory information, spectrum assignment details, and official telecommunications policy, the TRA website is the authoritative source.

Yes. To connect to a 5G network, your device must contain a 5G-compatible modem chip. 4G LTE phones cannot connect to 5G radio access nodes, even in areas with 5G coverage. If your device only supports 4G LTE, it will continue to use the 4G network and will not be affected by 5G deployment — it simply will not access 5G speeds.

5G smartphones became widely available from 2020 onwards. Most flagship and mid-range smartphones released from 2021 onward include 5G modems. When purchasing a new device, look for 5G NR (New Radio) compatibility, and check that the supported 5G bands match those deployed by networks in Oman — particularly mid-band bands such as n77 or n78 (around 3.5 GHz).

Yes. 4G LTE devices continue to function normally in areas where 5G is also deployed. 5G networks are designed to coexist with 4G LTE. In non-standalone (NSA) mode — the most common early 5G deployment approach — the 4G LTE network remains as the foundational layer, and 5G is added on top for devices that support it.

Your 4G device will continue to receive 4G service in these areas. The presence of 5G infrastructure does not interfere with or degrade 4G service for existing devices. The only limitation is that a 4G-only device will not benefit from the higher speeds and lower latency of 5G.

5G modems, particularly when actively transmitting and receiving data at high speeds, can consume more power than 4G modems. Early 5G modems were notably power-hungry, but modem technology has improved significantly with each generation. Modern 5G chips (such as those from Qualcomm, MediaTek, and Samsung Exynos/Modem) are engineered for efficient 5G operation, and the gap in power consumption compared to 4G has narrowed considerably.

In everyday use, a 5G phone connected to a 5G network may show slightly reduced battery life compared to the same device using 4G, particularly when actively using high-speed 5G data. Many 5G smartphones include settings that allow users to switch between 5G and 4G to manage battery life according to their preferences.

International health and scientific authorities, including the World Health Organization (WHO), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), and national health agencies in countries where 5G is deployed, have reviewed the scientific evidence and concluded that 5G technology, when deployed within established exposure guidelines, does not pose a known risk to human health.

5G operates using radio frequency electromagnetic fields (RF-EMF), which are non-ionising radiation — they do not carry enough energy to break chemical bonds or damage DNA, unlike ionising radiation such as X-rays or gamma rays. The ICNIRP guidelines set conservative exposure limits based on the full body of scientific research. 5G network deployments are required to comply with these limits. For the most current scientific consensus, the WHO's electromagnetic fields programme and ICNIRP publications are the authoritative sources.

This is a nuanced question. Individual 5G base stations, particularly mid-band Massive MIMO arrays, may have higher total transmitted power than a single 4G antenna. However, due to beamforming technology, the radio energy from a 5G base station is directed in focused beams toward devices rather than radiated uniformly in all directions as in 4G. This means that in locations not directly targeted by a beam, the actual RF exposure can be lower than from a 4G antenna radiating omnidirectionally.

Furthermore, 5G networks are required to operate within the same ICNIRP exposure limits that govern 4G and all other mobile network technologies. Regulatory bodies require operators to demonstrate compliance with exposure limits before deploying infrastructure. The additional frequency bands used for mmWave 5G are also non-ionising and do not have deeper penetration into the body than lower frequencies.
