ZDNET’s key takeaways

  • iPhones will support Bluetooth Channel Sounding in iOS 27.
  • Channel Sounding promises secure, fine-ranging Find My device capabilities.
  • Although exciting, adoption will be slow — per usual.

This year’s WWDC is over, and now it’s time for developers to fine-tune their apps and for early adopters to test them ahead of this fall’s public launch of iOS 27. AI dominated the conversation, serving as the foundation for upgrades to Siri, Search, Photos, and more, while some upgrades didn’t make it to the keynote.

One less-discussed iOS 27 feature is support for Channel Sounding, an innovative Bluetooth feature first announced in Bluetooth 6.0, which was released in the fall of 2024. Channel Sounding enables a Bluetooth-enabled device to perform precise localization, enhancing its spatial awareness of distance and direction.

Thanks to Bluetooth’s ubiquity and Apple’s support for Channel Sounding, some of the world’s most popular smartphones will support enhanced location compatibility with third-party Bluetooth headphones, smart locks, trackers, wallets, digital keys, and other location-based peripheral devices. 

Like always, it wouldn’t be an emerging Bluetooth technology if there weren’t a few caveats. More on that in a bit.

What does Channel Sounding mean for iPhone?

Channel Sounding’s most valuable benefit to consumers is its ability to democratize the Find My network. In a perfect world, all the devices you’d like to keep tabs on can be easily found in the Find My app, with exact distance and direction measurements, regardless of manufacturer. Channel Sounding aims to make this dream a reality.

With Channel Sounding, iPhone users can expect improved device-tracking functionality with third-party headphones, earbuds, Bluetooth trackers, and more.

As smartphones become digital keys for cars, smart locks, and safes, Channel Sounding promises secure, “centimeter-level accuracy” in location technology, ensuring that only your device can act as a key when within a specific range.

A smarter Find My network

Currently, Apple’s Find My Device feature works best with other Apple devices, specifically those with an ultra-wideband (UWB) chip. If you open Find My to look for your AirPods Pro 3, the Find feature that helps you track them down is enabled by the UWB chips in your iPhone and your AirPods. In its current state, Bluetooth is what can help with general directions, and UWB offers accurate direction and distance.

Conversely, if you misplace your Powerbeats Pro 2, Bluetooth steps in. You can only see where your Powerbeats were last connected to your iPhone via Bluetooth, since the Powerbeats lack a UWB chip.

Also: Will your iPhone support Siri AI? The answer is complicated

However, UWB chips are expensive to manufacture, and not all manufacturers see the need to incorporate them. These chips are more common in smartwatches and smartphones than in single-purpose peripheral devices, such as headphones, earbuds, or Bluetooth trackers.

As a result, if you have an iPhone and want enhanced device tracking, you’re locked into Apple’s ecosystem of UWB-equipped devices, including certain AirPods and AirTags. Yet Apple’s embrace of Channel Sounding will expand your Find My network, allowing Bluetooth technology to fill device location gaps in third-party devices that lack UWB chips.

What’s the catch?

At WWDC, Apple’s announcement of Channel Sounding support included guidance on how developers can begin optimizing their apps for their Bluetooth peripherals for iPhone, along with the requirements for doing so. Apple mandates that for a third-party Bluetooth device to be compatible with Channel Sounding on iPhone, it must support Bluetooth 6.3.

Channel Sounding is available only on iPhones with Apple’s N1 networking chip, which is found exclusively in the iPhone 17 lineup; future iPhones will likely have it or a more advanced chip that supports Channel Sounding.

Also: Every iPhone model that supports the iOS 27 update (and which older ones don’t)

The Bluetooth Special Interest Group, of which Apple is a member, adopted and released Bluetooth 6.3 on May 6, just a month before the latest WWDC. For context, many peripheral devices, such as headphones and earbuds, manufactured as recently as 2025, support Bluetooth 5.4.

So, we shouldn’t expect Bluetooth headphones, speakers, or earbuds to debut with Bluetooth 6.3 anytime soon. However, smartphones, smartwatches, trackers, and smart locks tend to adopt the latest Bluetooth technologies more quickly, especially from manufacturers of several device categories, such as Apple and Google. 

However, even for devices with quicker Bluetooth adoption, it will likely be at least a year before we see any widespread Channel Sounding on iPhone.

You’ve built your small business from the ground up. It’s your pride and joy, your financial security, and a potential legacy for your family. But what happens to your business interests after you’re gone? Without proper estate planning, your small business could face a chaotic future, disrupting operations, hurting employees, and jeopardizing your loved ones’ inheritance.

Business estate planning is your secret weapon. It’s not just for the ultra-wealthy with complex trusts and wills. For small business owners, it’s a crucial tool to ensure business continuity and protect your business value. Here’s how you can craft a comprehensive estate plan:

Know Your Business Inside and Out

The first step in your estate planning process is taking a deep dive into your business affairs. Make a list of all your business assets: equipment, inventory, intellectual property, and real estate.

Furthermore, don’t forget your business debts like loans and outstanding payments. This comprehensive list helps you understand what needs protecting and planning for in your estate planning documents.

Chart Your Business’s Future Course

What do you envision for your business after you’re gone? Should it stay in the family? Be sold to a trusted partner? Wind down entirely? This is where business succession planning comes in. It’s about deciding the future of your business in a way that honors your legacy and sets your team up for success.

Here are some questions to consider:

  • Family Business? Do you have a family member who shares your passion and has the skills to lead?
  • Trusted Partner? Is there a key employee you see as the ideal successor?
  • Time for a Change? Are you open to selling the business to ensure a smooth transition?

There’s no right or wrong answer. The key is to have open conversations with your loved ones and key employees to understand their goals and aspirations. This will guide you in crafting a business succession plan that feels right for everyone involved.

Develop a Rock-Solid Business Succession Plan

This plan outlines who will take over your business and how. You might identify a family member, a key employee, or even an outside buyer. The business succession plan should detail the transfer process, including training and timeline.

Here’s how to craft a plan as strong as your business itself:

  • Identify Your Successor: It could be a family member you’ve been mentoring, a trusted key employee, or even an outside buyer.
  • Groom Your Successor: Start by involving them in key decisions to give them opportunities to learn the ropes.
  • Plan for the Unexpected: Have a backup plan in place. Identifying another potential leader or outline a buy-out option for remaining partners.

An experienced estate planning attorney like Keele & Parke can help you draft a legally sound plan that considers state law and tax implications.

Avoid Conflict with Ironclad Sell Agreements

If you have co-owners, a sell agreement is vital. This agreement dictates what happens to a deceased or incapacitated owner’s share of the business. It prevents conflict among remaining partners and ensures a smooth ownership transition in your overall estate plan.

Wills vs. Trusts: Choosing the Right Tool

A will can designate who inherits your business assets. But the problem is it can be a slow and public process through probate court.

Here’s where a revocable living trust comes in. Think of it as a private vault that holds your business assets during your lifetime. You can name yourself as trustee, so you’re still in control.

Another thing, you can designate a successor trustee to seamlessly take over managing the business if you become disabled or pass away. This avoids probate and keeps things running smoothly for your loved ones and your employees.

Wills are still important for your overall estate plan, especially for personal assets outside the trust. But for your business, a revocable living trust offers flexibility, privacy, and peace of mind.

Minimize Estate Taxes Through Strategic Planning

Nobody wants a big chunk of their hard-earned business value going to the government after they’re gone. That’s where estate taxes come in, and they can be a real burden for your family. But don’t worry, there are smart estate planning strategies you can use to minimize the impact of these taxes.

  • Smart Business Structure: The legal entity you choose for your business can impact your estate taxes. Talk to your estate planning attorney about structuring your business as a limited liability company (LLC) or another entity that might offer tax advantages.
  • Explore Powerful Trusts: There are special types of trusts, like grantor retained annuity trusts (GRATs), that can be used to transfer ownership of your business interests to your heirs while minimizing the taxable value of those assets.

The right strategy for you will depend on your specific situation and goals. That’s why it’s crucial to work with an experienced estate planning attorney and financial advisor. They can help you create a personalized plan that minimizes your estate taxes and protects your legacy.

Don’t Neglect Your Personal Estate Plan

Your business is just one piece of the puzzle. You also need a personal estate plan that includes a will, power of attorney, and healthcare directives. Without it, your loved ones could face a legal mess during tough times. Bills might go unpaid, important decisions could be delayed, and family heirlooms could end up in the wrong hands.

An estate plan ensures your wishes are followed. It names guardians for your minor children, designates beneficiaries for your personal assets (like your home and savings), and appoints someone you trust to make healthcare decisions if you’re unable to. This gives your family peace of mind knowing they’re taken care of, even in your absence.

Life Insurance: A Lifeline for Your Loved Ones

A life insurance policy provides your beneficiaries with a lump sum of cash upon your death. This can be crucial for surviving family members or business partners, especially if they need to buy out another owner’s share through a sell agreement or pay estate taxes.

Regularly Review and Update Your Plan

Life circumstances change, and so should your estate plan. Regularly review your plan, especially after major life events like marriage, children, or changes in your business structure.

Seek Professional Guidance for a Comprehensive Plan

Business estate planning involves complex legal and financial considerations. Don’t try to go it alone. Consult with an experienced estate planning attorney specializing in business succession planning and a financial advisor with experience in small business matters. Their expertise can ensure your estate plan is comprehensive, legally sound, and achieves your goals for business continuity and protecting your loved ones.

Final Thoughts

Safeguarding your business is like protecting your family’s future. Take control. Schedule a consultation with an experienced estate planning attorney today. They’ll guide you through the process and ensure your legacy lives on.
