Wi-Fi for Voice and Video
Design Cisco or Meraki wireless around real-time voice and video, testing roaming, contention and prioritisation with the client devices people actually use.

Average response is not a resolution time or a contractual guarantee. Support scope and response commitments are agreed for each engagement.
Wi-Fi for voice and video needs consistent delivery, not simply a high headline download speed. MCI Network Services designs and reviews Cisco and Meraki wireless environments for the applications and devices your staff use in calls, meetings and mobile workflows. We examine airtime, roaming, prioritisation and the complete network path. The objective is to understand why a conversation becomes difficult and to build a service that supports the agreed workload without promising that one wireless setting can resolve every quality problem.
Coverage and capacity
Design Wi-Fi around the spaces, devices and traffic that depend on it.
Secure access
Align authentication, segmentation and guest access with the wider network.
Measured performance
Validate roaming, interference and user experience instead of relying on signal bars.
Identify the application and endpoint behaviour
A dedicated voice handset, a laptop meeting client and a room collaboration system can have different radio and traffic characteristics. We record the device families, software versions and typical use patterns. A design based on one endpoint should not automatically be applied to another, particularly where power-saving behaviour, supported bands or roaming capabilities differ.
We also ask when problems occur. Calls failing while walking, audio deteriorating in crowded rooms and video freezing only on external meetings suggest different investigation paths. The requirements define whether mobility is essential, how many simultaneous sessions are expected and which areas need service. This gives the project a useful target beyond the broad statement that the Wi-Fi should be faster.

Plan RF coverage for the client population
Coverage needs to support a two-way link with the actual endpoints. We assess placement, cell overlap and power levels against the relevant device and application guidance. Raising access-point power can make its signal easier to see without improving the client’s return transmission. The design considers that balance rather than treating maximum power as a universal fix.
Capacity is assessed separately. Real-time sessions can be sensitive to contention and retransmissions even when average bandwidth appears modest. We examine channel reuse, widths and the number of active clients in busy areas. An additional access point may help in a properly designed layout, but uncontrolled overlap can create more competition for airtime and make performance less predictable.

Review quality-of-service treatment end to end
Supported wireless prioritisation mechanisms can help classify traffic, but their usefulness depends on the wider path. We review how applications mark traffic, how the wireless and wired network interpret it and what happens at the WAN edge. A priority setting on the access point cannot guarantee that an external provider or congested upstream link treats the flow in the same way.
We agree which traffic should receive preferential treatment and avoid granting it indiscriminately to every application. Misclassification can reduce the value of the policy and make troubleshooting harder. The handover records the intended markings and trust boundaries, allowing the operations team to identify whether a later application or endpoint change has altered the behaviour the design relied on.
Different environments. The same care.
Built around the work
your network supports.
Finance, banking and the wider private sector. We start with the systems and people that depend on your connections.
Finance & banking
Market-data paths, routing and provider coordination on clients’ behalf.

Reliable access between people, workplaces and business applications.
Office network design ↗Data centres & cloud
Network boundaries, workload connections and operational ownership.
Data centre networks ↗Test mobility and authentication together
For mobile voice, roaming behaviour needs direct observation using representative devices. We assess supported assistance and fast-transition features alongside the security method, but the client still plays an important role in deciding when and where to roam. A configuration checkbox is not proof that every handset completes a transition quickly enough for the application.
We follow agreed routes while monitoring the call or session and the relevant network events. This distinguishes a radio coverage problem from authentication delay, addressing changes or an upstream path interruption. Where the endpoint requires a supported software update or a different profile, that work is coordinated with its owner. The network should not be repeatedly retuned to compensate for an unresolved client defect without evidence.
Separate wireless faults from application-path faults
A call can suffer even while the wireless link remains stable. We review DNS, firewall handling, WAN capacity and the path to the collaboration service where relevant to the scope. Observations from the application can help correlate quality symptoms with network events. We avoid diagnosing every poor call as interference simply because the user is connected wirelessly.
Testing includes busy and normal conditions where practical. We compare representative sessions and record the client, location and time. A short successful call during an empty-office visit does not establish performance during a full meeting schedule. The acceptance record states what was exercised and identifies any operating-period monitoring needed to complete the evidence.
Keep the service aligned with changing use
The final design or remediation plan records client assumptions, RF principles, priority treatment and validation results. New handset models, meeting software or room layouts can change demand and compatibility, so the operating process should include appropriate review. Monitoring is most useful when it connects symptoms to affected locations and applications rather than reporting only that access points remain online.
MCI can provide a targeted review or include real-time applications in a broader Wi-Fi validation survey. Share the affected devices, call platform and typical symptoms to establish the scope. We will distinguish what the wireless network can improve from dependencies that require action by endpoint, application or connectivity providers, keeping the recommendation tied to the actual user experience.
