Wi-Fi in Mobile Handsets Still on the Increase

In February 2009, ABI Research found that dual-mode cellular/Wi-Fi mobile handset shipments were set to double between 2008 and 2010. ABI analysts have now confirmed that a similar pattern will hold true for the period 2009-2011.

This year is on track to see 144 million handsets shipped, with forecasts for 2011 at just over 300 million.

"Wi-Fi's penetration into handsets has more momentum than the bad economy," says industry analyst Michael Morgan. "It has become a must-have item much as Bluetooth did earlier. But just having Wi-Fi in the handset isn't enough. You have to have a reason for customers to use it. Until now it has been predominantly for data use, with voice struggling to find its niche."

However mobile operator attitudes to Wi-Fi have been changing. At first many feared that Wi-Fi would take (voice/data) traffic off their networks, resulting in lost revenue. Now they're starting to realize that it may instead mean an increase in available network capacity.

How mobile service providers view Wi-Fi is largely a function of their particular circumstances, says Morgan. "Verizon has not enthusiastically embraced Wi-Fi in its handsets, while AT&T has. AT&T was thrown into the pool by the iPhone. Previously people did access data, but the iPhone led people to use Wi-Fi to a degree never seen before. Traditionally cautious Verizon hasn't been thrown into that situation yet, but they are warming up to Wi-Fi."

Wi-Fi benefits depend on a carrier's circumstances too. Consider T-Mobile: a wireless carrier that owns no landline assets. It used Wi-Fi to deliver an improved in-home service that it couldn't achieve before. In contrast, AT&T does have landline assets. Here Wi-Fi's benefit is to take a load off the AT&T mobile network.

"The picture may be unique to each carrier," Morgan concludes, "but in the end Wi-Fi can offer most operators those two key benefits: extended reach and/or network load reduction."

Digital Transformation Growth Defies Market Volatility

The forward-looking CEO's commitment to ongoing investment in Information Technology (IT) is persistent. Worldwide IT spending is forecast to total $4.4 trillion in 2022 -- that's an increase of 4 percent from 2021, according to the latest worldwide market study by Gartner, Inc.   "This year is proving to be one of the noisiest years on record for CIOs," said John-David Lovelock, vice president at Gartner . Regardless, digital transformation remains a high priority across the globe. Geopolitical disruption, inflation, currency fluctuations, and supply chain challenges are among the many market volatility factors vying for attention, yet contrary to what Gartner saw at the start of 2020, enterprise CIOs are accelerating IT investments in 2022. Digital Transformation Market Development As a result, purchasing and investing preferences will be focused on areas including data analytics, cloud computing, seamless customer experiences, and IT security. Inflation impacts on

IoT Device Management Demand Gains Momentum

More forward-thinking CIOs and CTOs are focused on the adoption of the Internet of Things (IoT). Management challenges are top of mind for those who have already deployed a large number of sensors and associated network edge devices. Device management services are evolving in response to a greater breadth of new device technologies such as edge intelligence and related connectivity solutions, as well as the customer scalability and security of IoT deployments. But forward-looking suppliers are also preparing for a world where 41.3 percent of the connected devices will be using some form of Low Power Wide Area (LPWA) technologies by 2026. IoT Device Management Market Development Since IoT customers increasingly need to manage a larger fleet of connected devices, ABI Research now forecasts that IoT device management services will exceed $36.8 billion in revenues by 2026. Standardization is beginning to play a bigger role in device management services, as more connected devices use LPWA t

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service.
