Wi-Rider Wireless Technology Trend

“Problem of Heterogeneous Wireless Network”
Although multiples of networks are accessible to the user's device, each of networks is not linked or "networked" with each other. In other words, all the networks are not sharing their information to other network operators, not collaborating to maximize QoS with other networks and not trying to minimize interference with others. It is mainly because the networks of today are designed, installed, managed exclusively by network operators (licensed) or house-hold (unlicensed) within their own network architecture.

“More Wireless Service to Users”
Today, we are being exposed to various wireless network services, and mobile devices are capable of accessing those wireless networks. The currently available wireless connection are cellphone networks (GSP, GPRS,WCDMA, HSPA, CDMA-EVDO), wireless local area network (WiFi - IEEE 802.11 a/b/g/n) and wireless personal area network(bluetooth).
In the near future, a device will have more wireless connection capability, such as WiMax (IEEE 802.16), Ultrawide band, ZigBee, RFID, 60GHz and 4th Generation mobiles (IMT-Advance). Even though today's devices have multiple wireless connection capabilities, carriers are controlling the user wireless connection mostly, while the user's demand and location are being ignored.

“More spectrums for Users”
Wireless networks are being operated on the licensed or unlicensed spectrum. Wireless networks running on licensed bands are being controlled by the carriers, who purchased the spectrum band. The carriers are trying their best to provide the highest quality-of-service and coverage to the users via a centralized classic telecommunications control structure. However they have limitations in improving the user's data throughput, mainly because of the narrow available bandwidth. The carriers expend a large capex budget to purchase the spectrum and build
ing out the network, which ultimately requires the user to provide the ROI via a subscription based telecom model.
On the other hand, wireless networks running on unlicensed bands, such as WiFi, can provide low cost solution for the users, since there is no need to purchase the spectrum and anyone can install the access point. However users are not guaranteed quality of service (QoS) and experience the interference issues since the unlicensed band is being shared with other wireless communications, such as Bluetooth and cordless phones.
