UK hotspot builder The Cloud has opened the first of several city center hotzones: The firm is building city center networks using Wi-Fi across nearly 10 cities, most of which are partly operational, ZDNet UK writes. The City of London (the square mile business district) is one of the most notable of these hotzones. Service runs £11.99 for a week or, with a year's commitment, £11.99 per month. The Cloud resells its network to many aggregators, including BT OpenZone and iPass, resells VoIP access to Vonage, and offers use to Nintendo DS game player owners.
