Starlink and Other Satellite Direct-to-Cell Services Effects on the Telecom Sector

It will be interesting to see how satellite direct-to-cell technologies impact the established telecom sector. Companies such as Starlink, AST SpaceMobile, Lynk Global, and others are aiming to deliver flawless satellite-based mobile device connectivity, therefore eliminating, in many cases, the requirement for conventional cell towers.

So we can assume 1. Removal of Coverage Gaps: Especially in Rural and Remote Areas. The current challenge is providing service in far-off locations because it is costly and challenging since traditional telecom networks depend on cell towers. By using satellite direct-to-cell service, rural and underdeveloped areas can have flawless access, and it will have a big impact on established mobile network operators who rely on coverage restrictions as an advantage.

2. Change of Network Infrastructure Spending: MNOs spend billions on 4G/5G cell towers and fiber backhaul. Should satellite-based coverage prove dependable and reasonably priced, and it will, sooner rather than later, reliance on terrestrial networks will, well, decrease significantly. Spending will shift; building more ground towers, I am not so sure that's the way to go.

3. Competition. Now, and for a while longer, traditional roaming agreements bring in enormous income. Satellite direct-to-cell skips conventional roaming so users can stay connected without requiring several carrier agreements. This will have a huge impact on the way big telecom companies make money.

4. Now, MNOs oversee the whole telecom ecosystem. Many telecom companies will try to team up with satellite companies to create hybrid solutions (satellite plus terrestrial coverage) instead of competing. T-Mobile & Starlinks partnership will include satellite services in their network. This will allow T-Mobile to maintain their position. AT&T's partnership with AST SpaceMobile is a move to not be left behind. Either way, I, for one, am looking forward to global coverage by one provider. Sure, rising competitiveness and pricing pressure will follow, so MNOs will have to lower prices to stay competitive.

5. Expansion of IoT and Industrial Connectivity: Now it's IoT devices in remote areas (agricultural, shipping, and mining) depending on unstable cellular coverage or costly satellite-based services. Direct-to-cell provides seamless connectivity for driverless cars, smart agriculture, supply chain tracking, and emergency services, so we will see IoT expansion.

6. Regulatory challenges and national security: I'm not sure, but data privacy and security, well, national security, I can imagine there will be some issues with satellite companies operated from another country. Let's see.

Even if satellites offer environmentally friendly coverage, launching and maintaining them is not cheap. Low-energy satellite designs might become the main emphasis of future solutions. And yes, satellite direct-to-cell services will transform the telecom sector; however, it will take a while before they totally replace terrestrial networks, with lots of hybrid solutions at first, satellite providers and conventional networks working together, and telecom reselling or rebranding satellite services. Regardless, a change toward a worldwide connectivity market will favor those who value satellite alliances and include next-generation connectivity into their product lines as early as they can.

Encryption key (Kc)
The SIM includes the algorithm (A8) that generates the 64-bit encryption key (Kc). We calculate the encryption key by applying the same random number (RAND) from the authentication process to the encryption key generation algorithm (A8), using the single subscriber authentication key (Ki). The MS and the BS use the encryption key (Kc) to encrypt and decrypt the data. However, a passive GSM interceptor can remotely extract the encryption key, calculate it, and then use it for real-time decryption.

The UM interface of the GSM mobile radio standard uses the BCCHA broadcast control channel (BCCH), a point-to-a unidirectional multipoint channel (downlink). The BCCH transmits a repeated pattern of system information messages describing the identity, configuration, and available functions of the base transceiver station (BTS).

BCCH manipulation
A special technique. GSM interceptors (IMEI/IMSI catchers) use BCCH manipulation to create a “virtual power effect” of up to several hundred watts. A GSM interceptor uses this to trick the handsets that will always dial the “BTS” with the strongest signal. In addition, by changing the Cell ID (all other network parameters remain the same—MCC, MNC, LAC) and the ARFCN, the interceptor forces the mobile phones in the area to send registration requests and, in this way, to collect the phone ID.

BTS
A Cell Tower. The base transceiver station contains the equipment for sending and receiving radio signals (transceivers), antennas, and equipment for encrypting and decrypting communication with the base station controller (BSC).

A carrier is a company that offers GSM telecommunications services. Cell A single base station serves a cell in personal communication systems (cellular telephone systems). The arrangement of cells allows for the reuse of base station frequencies across cells. The environment of a cell site. The processing of calls from a specific cellular location takes place in this area.
Cell identifier: When a Base Transceiver Station (BTS) or a sector of a BTS is not part of a GSM network, it uses a GSM Cell ID (CID), which is typically a unique number. In some cases, the last digit of the CID represents the sector ID of the cells. TGSM interceptors use this network parameter for what is known as BCCH manipulation. By changing the Cell ID (all other network parameters remain the same—MCC, MNC, LAC) and ARFCN, the system forces the cell phones within the range to send registration requests and, in this way, to collect phone IDs.

Cell location
The base station antenna, along with other transmitting and receiving equipment, links a mobile phone to the network.

Channel coding
Channel coding is the technique of protecting communications signals from signal degradation by adding redundancy to the communications signal.

Fading
A fade is a slow change in signal strength.

Summary and additional

Mobile security is critical in an era where phone interception by hackers, corporations, and governments is routine. Interception invades privacy, enabling control, embarrassment, or even persecution. Despite legal controls on interception technology, widespread warrantless surveillance blurs the line between legal and illegal actions. Cell towers can track mobile phones through their IMEI (phone ID) and IMSI (SIM ID), making users susceptible to monitoring, even in the absence of a SIM card. Most “secure phones” rely on encryption, but this alone can’t protect against advanced interception tools. Skilled attackers can intercept calls, texts, and data traffic, while radio jammers can render even encrypted devices vulnerable. Truly secure phones must detect interception attempts in real time, allow IMEI/IMSI changes, and spoof locations to mislead trackers. Some devices address these threats by detecting and alerting users to interception, supporting automatic ID changes, and enabling location spoofing via cell tower manipulation. Unlike traditional encryption-based solutions, they exploit network vulnerabilities to shield user identities, ensuring communications remain confidential and untraceable.

A5 / 3: even stronger encryption with an open design. Also known as Kasumi. Certain 3G and 4G cellular networks utilize Kasumi.

The GSM cellular standard uses A5/1Stream encryption to protect wireless communication. Initially, it remained secret, but leaks and reverse engineering made it public knowledge. Researchers have identified several serious vulnerabilities in the cipher. Europe and the USA utilize the cipher A5 / 1.

The GSM mobile phone protocol uses A5/2 stream encryption to protect voice. A5/2 was an intentional weakening of the algorithm for certain export regions.

UMTS, GSM, and GPRS mobile communication systems use the block cipher A5/3A5/3. The confidentiality and integrity algorithms in UMTS use KASUMI under the names UEA1 and UIA1. The A5/3 keystream generator in GSM and the GEA3 keystream generator in GPRS both use KASUMI.

ARFCN / EARFCN A radio frequency absolute channel number (ARFCN) in GSM cellular networks identifies a pair of physical radio operators, one for the uplink signal and one for the downlink signal, that transmit and receive in a land mobile radio system. Mobile phones use this network parameter to direct registration requests to the correct BTS (IMEI/IMSI catcher). LTE EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number. The EARFCN number is in the range 0 to 65535.

Authentication Key (Ki)
The 128-bit Authentication Key (Ki) serves for both authentication and encryption key generation. The GSM network uses the key to authenticate the SIM. The operator assigns this key to each SIM card during the personalization process. The design of the SIM card ensures that a smart card interface cannot compromise its Ki.

Camera Lock
When a device has this feature, the user can lock the camera at any time and thus prevent remote activation for spy images and video. This will have monitoring and warning functions directly on the start screen to make it easy to access by sweeping to bring it up.

GPS Removed
Both the software and hardware levels of some devices allow the user to deactivate the GPS module.

Calibration
Devices running on 2G and 3G networks come with a calibration app that you must use to sync the GSM and country code for the SIM, ensuring correct calibration when you activate the device.

Virus-free and Secured by Default
Devices are by default immune to viruses, malware, or spyware. The user cannot deactivate or install the app. Remote code ex*****on" is not possible.

Volatile USB filters safeguard phones from forensic investigations. No forensic device can extract any data or files from the phone. The volatile USB filters cause the motherboard to self-destruct as soon as the phone connects to a PC or service box, putting the phone into protected mode.

Sandbox Setup
We have moved the IMEI engine, IMSI engine, and other software components to a separate partition (sandbox) for faster and smoother operation. We have suppressed the system restart in case of abnormal network properties like IMSI or GSM Interceptor.

Encrypted & Signed Firmware
A signed firmware allows for the verification of any tampering upon request.
