O2 will offer iPhone 3G for free along with extensive Wi-Fi coverage: AT&T may still be sorting out how Wi-Fi service will be included in its cell plans, but O2 had already provided free Wi-Fi to supplement scanty EDGE service in the UK. The new iPhone 3G will be offered fully subsidized to subscribers of £45 or higher tariffed services, along with 9,500 hotspots through BT OpenZone and The Cloud.

SanDisk buys MusicGremlin: The innovative Wi-Fi-enabled music player was and remains far in advance of the features found in the iPod touch, iPhone, and Zune, but the company behind the product couldn't get a fire lit under it. Sales figures were never disclosed, but it's never been on the list of top-selling players in the market. SanDisk's acquisition will shut down the product and its music service, but it will absorb the people and technology. I met with the founders of the company many years ago, and were impressed by how far ahead they were of everyone in the industry.

Zyxel introduces VOIP-connected Wi-Fi camera: I think they threw a bunch of buzzwords into a blender, but it's rather clever. The camera connects to a network via Wi-Fi, and has SIP (Session Initiation Protocol) embedded. SIP is used for VoIP and as part of gatewaying Internet telephony. The V750W gets its own phone number, and can be controlled remotely through either a real phone using the public telephone network, or a soft phone using SIP. It's being resold, not sold to consumers directly, as a monitoring tool. It includes two-way audio. The camera can also place a phone call if an intruder monitor is tripped. Why not just give it an IP address like other such cameras? SIP, if implemented correctly, can traverse private networks' NAT (Network Address Translation) gateway limits.

BT opens up its hotspot network, while maintaining control: Can BT, by controlling the hardware and network infrastructure, let businesses effectively become new hotspots in its OpenZone network? I discuss this and more in this mobile post.

The notion is that visitors can gain Internet access by using an existing OpenZone subscription, paying a fee (the business can sell vouchers), or being a member of a roaming network. The business customers receive 50 to 500 minutes of use on OpenZone each month themselves, based on their BT contract for broadband.

This business hotspot option extends a previous relationship for residential users with Fon that allows BT home users to flip a switch and become a Fonero.

These kinds of organic extensions of networks have very little impact on the party that's sharing their broadband, because there's almost no work involved. But if enough people opt in, it can have a large impact on the amount of hotspot service that's available. While I have critique Fon for its backside-utility quotient--how readily one can get work done or even make a phone call at many Foneros' locations--the BT business plan assures that hotspots will be in places where people work and gather.
