Most 4G Wireless Networks Arrive in 2012 to 2014

Yet another market study has uncovered delays in the planned migration to forth-generation wireless networks. Infonetics Research recently published their 4G Strategies: Global Service Provider Survey.

Senior Infonetics analysts asked operators about their 4G network build-out plans, deployment strategies, challenges, technical and commercial drivers -- plus, the 4G services, applications, and devices they plan to offer.

"Better spectral efficiency tops the list of technical drivers for service providers upgrading to 4G," notes Richard Webb, directing analyst for WiMAX, microwave, and mobile devices at Infonetics.

"We asked service providers around the world when they anticipate their 4G networks will be complete with commercial services running. Two-thirds said 2012 to 2014, which is a realistic timeframe when an equipment and device ecosystem based upon an IMT-Advanced definition of 4G seems likely," adds Stéphane Téral, Infonetics Research's principal analyst for mobile and FMC infrastructure.

Infonetics surveyed knowledgeable purchase decision-makers at wireless service providers in Europe, the Middle East, and Africa (52 percent), North America (24 percent), Asia Pacific (24 percent), and Central and Latin America (5 percent) that operate a wireless network and have plans to deploy 4G.

Infonetics 4G Survey Summary Results Follow:

- 82 percent of service provider respondents plan to follow the W-CDMA to LTE deployment scenario, and of those, 53 percent plan to deploy HSPA+ before LTE.

- Half of the service providers believe 4G downlink speed will be between 25Mbps and 50Mbps at service launch, while 42 percent believe downlink speeds will be in excess of 50Mbps, suggesting that operators are getting more ambitious.

- 82 percent of service providers say they plan to launch mobile VPN services, showing the growing importance of the mobile enterprise business.

- Service providers appear to have sorted out their voice migration strategy (which was unclear in a similar Infonetics survey conducted last year), with IMS identified as the key architecture.

- Over half of the service providers surveyed plan to offer voice services over 4G one year after commercial launch.

Mobility-as-a-Service Creates Disruptive Travel Options

Building on significant advances in big data, analytics, and the Internet of Things (IoT), more innovative transit service offerings aim to increase public transport ridership and reduce emissions or congestion within metropolitan areas. By providing these services through smartphone apps, the transit services also significantly increase user convenience, providing information on different human mobility offerings -- including public transport, ridesharing, and autonomous vehicles. Mobility-as-a-Service Market Development According to the latest market study by Juniper Research, Mobility-as-a-Service (MaaS) subscribers will generate $53 billion in revenue for MaaS platform providers by 2027 -- that's rising from $5.3 billion in 2021. Let's start with a basic definition. MaaS is the provision of multi-modal end-to-end travel services through single platforms, by which users can determine an optimal route and price. The study identified a monthly subscription model as key to incr

Robocall Mitigation Solutions to Halt Criminal Threats

If you answer the phone and hear a recorded message instead of a live person, it's likely a robocall. A robocall is a phone call that uses a computerized autodialer to deliver a pre-recorded message. In 2020, the U.S. Federal Trade Commission (FTC) received 2.8 million consumer complaints about robocalls. Offering solutions to robocalling and associated fraudulent business practices, computerized mitigation platforms are an integral part of the solution. Platforms that are focused on actionable systems to disrupt unsolicited and potentially criminal phone calls help telecom service providers and industry regulators. Issues of whether one-size-fits-all developments are sufficient to be effective across the spectrum need to be addressed, and whether a single telecom network operator working unilaterally with a third-party platform could compromise desired or mandatory industry-wide standards. Robocall Mitigation Market Development According to the latest worldwide market study by Jun

Secure Digital Workspace Apps Enable the Future Enterprise

In early 2020, as the world responded to the COVID-19 pandemic disruption, many organizations were forced to rapidly transform their communications networks and IT infrastructure to support an unprecedented shift to remote work. Before the pandemic, approximately 38 percent of employees were remote full-time or had a flexible work arrangement where they split time between home and office locations. During the pandemic, the percentage of remote workers that CIOs had to support reached almost 72 percent. Future Enterprise Technology Market Development Enterprise leaders have been forced to adapt to a new state, shifting from traditional office-based operations to distributed workforce environments that must still provide the same level of connectivity, security, and efficiency across the organization. According to the latest worldwide market study by International Data Corporation (IDC), addressing connectivity across geographies and transforming networks to become more virtual and agile
