1. Plan

A successful WiFi deployment starts with a detailed plan phase.

This phase begins with gathering initial specifications such as WiFi coverage, number of clients, types of devices and defining critical business applications.

Services available in the "Plan Phase" are WiFi consultancy, network and WiFi surveys.

2. Design

Combining the initial customer specification and information gathered during planning we can start the consultative detailed design phase.

Coverage, capacity, applications, security are just some of the key elements taken into consideration for our designs while capturing the future aspirations of the network.

3. Integrate

Experience is the key element to success when installing and integrating wireless networks and with nearly 15 years’ experience there isn't a lesson we haven’t learnt.

Our engineers are extensively trained in physical installations, working at height, health and safety and they have active involvement in continually improving our processes. We have performed installations across Europe in the most complex of environments from manufacturing plants, warehousing, corporate offices, high streets and shopping malls.

4. Optimise

Validate the installed WiFi network against specifications and refine configurations for optimum performance.

Optimising ensures what was detailed in the planning and design phases have been delivered on. Taking the results from a validation survey and fine tuning adjustment as required.

5. Maintain

Upon successful project completion it is time to maintain.

Maintenance ensures the ongoing performance and support required by networks. Maintenance services are tailored to each specific network and customer need.

Is it time to take the 802.11ac Wi-Fi plunge?

802.11ac's mind-bending specifications will allow you to enjoy speeds of up to 1Gbps which is the Holy Grail if you are looking to rip out those nasty cable runs and start wirelessly transferring large files such High Definition video and Audio, but what does that mean for businesses?

The new standard will take the choice cuts of the current standard and evolve those technologies. One of the key features of the 802.11n standard is MIMO (Multi-in Multi-out) this technology revolutionised the wireless industry, 802.11ac will expand this technique with MU-MIMO (Multi-User Multi-in Multi-out) Currently AC's life is only in phase one which only supports SU-MIMO (Single-User Multi-in Multi-out) This essential means that only one client rather than multiple clients can take advantage of potentially up to eight spatial streams. AC is yet to be ratified and MU-MIMO won't be a working feature until phase two of the AC standard which may not arise until 2015.

Other matters to consider are range and interference. AC supports wider channel widths such as 80MHz and 160MHz. Typically as the channel width increases the power will decrease to compensate. This will have an effect on the overall range of the access point and therefore the potential coverage area will be less, more access points may be required to cover the same area as a 802.11n access point. Also as widths increase the available usable channels will decrease, using 80MHz for example will hog four channels of the 5GHz spectrum leaving it more open to co-channel interference. Using the full 160MHz will leave virtually nothing.

No one can deny that AC has huge potential to take wireless networking to the next level but in its current state it is just not ready. Wireless's reigning champion 802.11n is still the weapon of choice for enterprise level projects and will be for some time. Most manufactures for enterprise level wireless products are holding back until AC's potential can be fully harnessed before releasing any product.
