Hotspots are wi-fi regions where internet is easily available for devices which have a wi-fi receiver, which almost all smart phones, laptops and tablets have. This forces people to look for hotspots in every cafe they go to every neighborhood they pass though. Most of the private hotspots are locked and require a key which is known by the owner of the house. For people who do not have access to 4G networks, wi-fi is the only option for these people.
There is another technology that is available in select cities which offers wi-fi like feasibility and speeds such as 4G. This is WiMAX from WiMax technologies. The inclusion of Wimax in smart phones and laptops has begun with a few manufacturers creating mobile phones that are capable of accessing internet through Wi-max. The best part about wi-max is that it is available in throughout the town and is very penetrative. Places where it is even hard to get a mobile network, wi-max can easily reach these areas and help you do you office work. In places such as the middle of parks in big cities to every cafe and house in the city comes under this network. Even homes can utilize these wi-max networks by utilizing routers that obtain wi-max networks and supply it to other computers in the home. The speed of wi-max reached up to 10Mbps data speeds and more than 6Mbps upload speeds. Manufacturers are producing mobile LCD screens that will provide wireless televisions that will help in watching live television anywhere. VoIP is being run on wi-max signals, where receiver is embedded into the VoIP console and it can be ported anywhere like a wireless mobile phone. Although wimax networks are being phased out for the more expensive 3G and 4G networks which charge high data rates for anyone vying for them, they still are present a few cities.
