Es­sen­tial Com­po­nents for Wi-Fi Call­ing for ‘Al­ways-On’ So­ci­ety

Voice&Data - - PREEONPLDES -

As tech­nol­ogy ad­vances, the de­mand for an ‘al­ways-on’ so­ci­ety is be­com­ing more preva­lent. The num­ber of mo­bile de­vices con­tin­ues to in­crease ex­po­nen­tially and added pres­sures on the net­work mean mo­bile net­work op­er­a­tors (MNOs) need to do more to en­sure cus­tomers are con­stantly re­ceiv­ing a re­li­able and ro­bust ser­vice that meets their de­mands.

While mo­bile op­er­a­tors might take com­fort as the mar­ket looks to­wards pro­jected growth, there are other areas of the world that are de­vel­op­ing. They are find­ing new ways to be­come more re­source­ful, but this is ac­tu­ally hin­der­ing the ser­vice pro­vided by MNOs. New build­ings are be­ing de­signed and built in more en­vi­ron­men­tally friendly ways and the ‘green’ ma­te­ri­als – such as the metal-ox­ide coat­ing on glass win­dows – are in fact im­ped­ing mo­bile sig­nals to users in­side. This makes it harder for MNOs to de­liver the ser­vice their cus­tomers want (and pay for) which re­sults in a dis­sat­is­fied cus­tomer base. This is a prob­lem no net­work op­er­a­tor can af­ford to have in such a fiercely com­pet­i­tive en­vi­ron­ment.

It has quickly be­come ap­par­ent that Wi-Fi can be uti­lized to solve this is­sue, and many MNOs have re­alised that by lever­ag­ing ex­ist­ing Wi-Fi net­works – which have be­come ubiq­ui­tous al­ready – con­sumers can still ben­e­fit from all of their sub­scrip­tion pack­ages through ser­vices like Wi-Fi call­ing. While voice over Wi-Fi isn’t a new tech­nol­ogy, pro­vid­ing car­ri­er­class na­tive Wi-Fi call­ing is a lu­cra­tive op­tion for MNOs. Un­like over-the-top (OTT) ser­vices like Skype and What­sApp, Wi-Fi call­ing is in­te­grated into the phone rather than via a third party app. How­ever, it does mean that the MNO needs to hand over crit­i­cal in­for­ma­tion and de­liver ser­vices on an in­fra­struc­ture that isn’t their own. This is a com­plete change in mind­set for op­er­a­tors, as sud­denly it means qual­ity of ser­vice (QoS) is out of their hands, they have to re­lin­quish con­trol to a wire­less in­fra­struc­ture they can’t guar­an­tee, and ef­fec­tively, put their rep­u­ta­tion on the line.

In or­der to make sure this doesn’t cre­ate a prob­lem, it’s cru­cial that MNOs in­vest in a wire­less in­fra­struc­ture that is ready to sup­port a car­rier-class ser­vice. This is also true for en­ter­prises wish­ing to build their own, wholly-owned net­works. Su­pe­rior, en­ter­prise-grade wire­less net­works can be de­fined by their abil­ity to de­liver the fol­low­ing:

High-den­sity, high­per­for­mance

There shouldn’t be a dip in cov­er­age or call qual­ity be­cause more clients want to use the net­work. A strong ra­dio fre­quency (RF) sig­nal from a smart an­tenna will help to mit­i­gate in­ter­fer­ence by con­tin­u­ously op­ti­miz­ing the RF path to the client in real time. The smart an­tenna en­sures the client main­tains the high­est pos­si­ble data rates even in poor RF con­di­tions, this helps re­duce the neg­a­tive ef­fects of dropped pack­ets and jit­ter on real time data traf­fic.
